  • New videos available #dax #ssas #powerpivot

    - by Marco Russo (SQLBI)
    The collaboration I and Alberto started with Project Botticelli is starting producing content. At this point we have three videos available: DAX in Action shows the power of DAX in PowerPivot solving common patterns not so easy or fast to solve in other languages DAX: Calculated Columns vs. Measures shows the difference between calculated columns and measures in DAX Introduction to DAX has a content corresponding to the title! The first two videos are freely available, the third one is longer and visible only to subscribers. The goal for this series of video is to reach advanced Excel users and BI developers that are new to DAX. If we should categorize this content, it’s a sort of level 200 session in a conference. I don’t expect readers of this blog to watch this video (if not for the sake of curiosity!) but if you have to explain this subject to anyone else and you have other priorities… well, you can add this post to the list of resources you provide for studying the subject!

  • My Last "Catch-Up" Post for 2010 Content

    - by KKline
    I did a lot of writing in 2010. Unfortunately, I didn't do a good job of keeping all of that writing equally distributed throughout all of the channels where I'm active. So here are a few more posts from my blog, put on-line during the months of November and December 2010, that I didn't get posted here on SQLBlog.com: 1. It's Time to Upgrade! So many of my customers and many of you, dear readers, are still on SQL Server 2005. Join Kevin Kline , SQL Server MVP and SQL Server Technology Strategist...(read more)

  • How to avoid or minimise use of check/conditional statement in my scenario?

    - by Muneeb Nasir
    I have scenario, where I got stream and I need to check for some value. If I got any new value I have to store it in any of data structure. It seems very easy, I can place conditional statement if-else or can use contain method of set/map to check either received is new or not. But the problem is checking will effect my application performance, in stream I will receive hundreds for value in second, if I start checking each and every value I received then for sure it effect performance. Anybody can suggest me any mechanism or algorithm to solve my issue, either by bypassing checks or at least minimize them?

  • Which stages of the requirements analysis process in mobile requirements engineering are the most challenging ones?

    - by user363295
    I'm doing a research on formulating a requirements analysis model as a stage of requirements engineering for mobile-application development by considering the limitations and the needs of it ( agility and etc.. .), what I'm trying to figure out is that which parts of this process (requirements analysis for mobile development) are the most challenging ones ( so i can focus more on) , and if there is any stage that u think I need to include or exclude (exp. some may think a quality plan may or may not be necessary and etc.) to make it more clear below is the list of few of the areas in which I can focus on ( by the way your suggestions can be anything out of the below list.) -Requirements specification -Prototyping -Requirements Prioritization -Focusing on quality functions

  • Approach for packing 2D shapes while minimizing total enclosing area

    - by Dennis
    Not sure on my tags for this question, but in short .... I need to solve a problem of packing industrial parts into crates while minimizing total containing area. These parts are motors, or pumps, or custom-made components, and they have quite unusual shapes. For some, it may be possible to assume that a part === rectangular cuboid, but some are not so simple, i.e. they assume a shape more of that of a hammer or letter T. With those, (assuming 2D shape), by alternating direction of top & bottom, one can pack more objects into the same space, than if all tops were in the same direction. Crude example below with letter "T"-shaped parts: ***** xxxxx ***** x ***** *** ooo * x vs * x vs * x vs * x o * x * xxxxx * x * x o xxxxx xxx Right now we are solving the problem by something like this: using CAD software, make actual models of how things fit in crate boxes make estimates of actual crate dimensions & write them into Excel file (1) is crazy amount of work and as the result we have just a limited amount of possible entries in (2), the Excel file. The good things is that programming this is relatively easy. Given a combination of products to go into crates, we do a lookup, and if entry exists in the Excel (or Database), we bring it out. If it doesn't, we say "sorry, no data!". I don't necessarily want to go full force on making up some crazy algorithm that given geometrical part description can align, rotate, and figure out best part packing into a crate, given its shape, but maybe I do.. Question Well, here is my question: assuming that I can represent my parts as 2D (to be determined how), and that some parts look like letter T, and some parts look like rectangles, which algorithm can I use to give me a good estimate on the dimensions of the encompassing area, while ensuring that the parts are packed in a minimal possible area, to minimize crating/shipping costs? Are there approximation algorithms? Seeing how this can get complex, is there an existing library I could use? My thought / Approach My naive approach would be to define a way to describe position of parts, and place the first part, compute total enclosing area & dimensions. Then place 2nd part in 0 degree orientation, repeat, place it at 180 degree orientation, repeat (for my case I don't think 90 degree rotations will be meaningful due to long lengths of parts). Proceed using brute force "tacking on" other parts to the enclosing area until all parts are processed. I may have to shift some parts a tad (see 3rd pictorial example above with letters T). This adds a layer of 2D complexity rather than 1D. I am not sure how to approach this. One idea I have is genetic algorithms, but I think those will take up too much processing power and time. I will need to look out for shape collisions, as well as adding extra padding space, since we are talking about real parts with irregularities rather than perfect imaginary blocks. I'm afraid this can get geometrically messy fairly fast, and I'd rather keep things simple, if I can. But what if the best (practical) solution is to pack things into different crate boxes rather than just one? This can get a bit more tricky. There is human element involved as well, i.e. like parts can go into same box and are thus a constraint to be considered. Some parts that are not the same are sometimes grouped together for shipping and can be considered as a common grouped item. Sometimes customers want things shipped their way, which adds human element to constraints. so there will have to be some customization.

  • Drop in service for account management, authentication, identity?

    - by Mike Repass
    I'm building an Android app and associated set of web services for uploading/downloading data. I need a basic (no frills) solution for account management (register, login, logout, verify credentials/token). What open source / third party solutions exist for this scenario? I need: create a new account db based on a salt simple web service to create a new account simple web service to authenticate supplied credentials and return some sort of token That's it, I can get by without 'fancy' email activation or password reset for the time being. Are there off-the-shelf components for this? Should I just use a 'blank' django or rails app to get this done? Seems crazy for everyone to be doing CREATE TABLE user_accounts ... Thoughts? Thank you.

  • Clustering Strings on the basis of Common Substrings

    - by pk188
    I have around 10000+ strings and have to identify and group all the strings which looks similar(I base the similarity on the number of common words between any two give strings). The more number of common words, more similar the strings would be. For instance: How to make another layer from an existing layer Unable to edit data on the network drive Existing layers in the desktop Assistance with network drive In this case, the strings 1 and 3 are similar with common words Existing, Layer and 2 and 4 are similar with common words Network Drive(eliminating stop word) The steps I'm following are: Iterate through the data set Do a row by row comparison Find the common words between the strings Form a cluster where number of common words is greater than or equal to 2(eliminating stop words) If number of common words<2, put the string in a new cluster. Assign the rows either to the existing clusters or form a new one depending upon the common words Continue until all the strings are processed I am implementing the project in C#, and have got till step 3. However, I'm not sure how to proceed with the clustering. I have researched a lot about string clustering but could not find any solution that fits my problem. Your inputs would be highly appreciated.

  • How to model the components of a non Information System?

    - by Adel C Kod
    So I am working on a project that's related to the Kernel code(specifically related to the TCP/IP stack of the kernel). I need to build some models to describe the functionality and components of my system. Initially I thought about Class Diagram, it can describe the general architecture of my system but it doesn't make sense since my code is VERY structured(written in standard C). I also thought about DFDs, they'd describe the processes of my system, and how the data is flowing. But they contain something which doesn't really fit in; data-storages. I have no databases here(at all). For the functionality, other team members suggested using Activity and Sequence diagrams, which is kinda okay with me, but what about the system components? So basically my question is; I want to describe the components of my system; what do you suggest as a meaningful diagram to follow? (Again, the project is a research low-level systems-oriented project with almost no user-interface at all)

  • Is ROA a specific form of doing SOA?

    - by JohnDoDo
    I have read somewhere that ROA (Resource Oriented Architecture) is SOA (Service Oriented Architecture) with specific constraints added. SOA is the abstract concept of combining discrete pieces of software and ROA is an implementation of SOA with all of the constraints of RESTful services applied to it: SOA = the concept ROA = the concept + specific implementation details I also had my share of posts saying that ROA is different than SOA, then simply fallback to statements like "ROA is REST" and "SOA is SOAP" and presenting the same more or less pertinent comparisons and differences between SOAP and REST. So just to clear up my confusion: Is ROA a specific form of doing SOA?

  • Is there a correlation between complexity and reachability?

    - by Saladin Akara
    I've been studying cyclomatic complexity (McCabe) and reachability of software at uni recently. Today my lecturer said that there's no correlation between the two metrics, but is this really the case? I'd think there would definitely be some correlation, as less complex programs (from the scant few we've looked at) seem to have 'better' results in terms of reachability. Does anyone know of any attempt to look at the two metrics together, and if not, what would be a good place to find data on both complexity and reachability for a large(ish) number of programs? (As clarification, this isn't a homework question. Also, if I've put this in the wrong place, let me know.)

  • Saving all hits to a web app

    - by bevanb
    Are there standard approaches to persisting data for every hit that a web app receives? This would be for analytics purposes (as a better alternative to log mining down the road). Seems like Redis would be a must. Is it advisable to also use a different DB server for that table, or would Redis be enough to mitigate the impact on the main DB? Also, how common is this practice? Seems like a no brainer for businesses who want to better understand their users, but I haven't read much about it.

  • How should I compress a file with multiple bytes that are the same with Huffman coding?

    - by Omega
    On my great quest for compressing/decompressing files with a Java implementation of Huffman coding (http://en.wikipedia.org/wiki/Huffman_coding) for a school assignment, I am now at the point of building a list of prefix codes. Such codes are used when decompressing a file. Basically, the code is made of zeroes and ones, that are used to follow a path in a Huffman tree (left or right) for, ultimately, finding a byte. In this Wikipedia image, to reach the character m the prefix code would be 0111 The idea is that when you compress the file, you will basically convert all the bytes of the file into prefix codes instead (they tend to be smaller than 8 bits, so there's some gain). So every time the character m appears in a file (which in binary is actually 1101101), it will be replaced by 0111 (if we used the tree above). Therefore, 1101101110110111011011101101 becomes 0111011101110111 in the compressed file. I'm okay with that. But what if the following happens: In the file to be compressed there exists only one unique byte, say 1101101. There are 1000 of such byte. Technically, the prefix code of such byte would be... none, because there is no path to follow, right? I mean, there is only one unique byte anyway, so the tree has just one node. Therefore, if the prefix code is none, I would not be able to write the prefix code in the compressed file, because, well, there is nothing to write. Which brings this problem: how would I compress/decompress such file if it is impossible to write a prefix code when compressing? (using Huffman coding, due to the school assignment's rules) This tutorial seems to explain a bit better about prefix codes: http://www.cprogramming.com/tutorial/computersciencetheory/huffman.html but doesn't seem to address this issue either.

  • Sources of requirements? [closed]

    - by user970696
    I was reading a book about SW engineering the other day and it went like: Sources of both functional and non-functional requirements are: law (for specific cases) business and user requirements etc. //what else then? So the question is, what other sources of requirements there are when an analyst is gathering the information? Lets consider a desktop app for mobile operator. As for the comment, I do not think this is a broad question as the books usually mention 1-2 sources. I would like to know more, if anyone can help.

  • How do I debug a cluster running Microsoft server 2003?

    - by alcor
    I'm sole developer of a complex critical software system, written in Visual C++ 2005. It's deployed on a classical Microsoft cluster scenario (active/passive), that has Windows Server 2003 R2. If a server A goes down, the other one (B) starts and take the ownership of its duties. You have to know that: Both servers have the same Microsoft patches/fixes, same hardware, same everything. Both servers use the same memory storage (a RAID-6 through fiber channel). This software has a main module that launches the peripheral modules. if a peripheral module crashes, the main module restarts it. When I switch the application in one of the two servers (let's say the B server) two of the peripheral modules of the main applications just started to crash apparently without reason about 2 seconds after the start of the peripheral module. What could I do to analyze/inspect/resolve this weird situation?

  • Desktop GUI Client - Remote RDBMS communication

    - by magom001
    Sorry if I am asking a trivial question but I have been searching for a while without any luck. I need to design a system and I am looking for advice on the technology that should be used. The layout is very simple: it is a sales application with a centralized database and multiple clients. Each salesperson has GUI app installed on his/her laptop that should be able to connect to the database to retrieve data and upload data (i.e. register new orders). My question is the following: how should the communication between the client and the server be implemented? I doubt that connecting directly to the RDBMS is a good idea... Should I use web-services? XML-RPC? How to implement authentication and encode the data? Thanks for your advice!

  • How can I pull data from PeopleSoft on demand?

    - by trpt4him
    I work in IT at a university and I'm working with about 5 different departments to develop a new process for students to apply to a specific school within the university (not the university as a whole). We're using a web-based college application vendor and adding the applicant questions for the school itself to the main university application. Currently the main application feeds into PeopleSoft. The IT staff here is building a new table to hold just our school's applicant data. I want to be able to access that data from PeopleSoft for use in external applications, but our IT staff doesn't really seem to understand what I'm requesting, as they simply tell me I can have access to the PS query tools. The problem is, I don't want to run just ad hoc queries, I want to be able to connect from outside PeopleSoft and show current data within the external app. I am unable to find documentation or get a clear answer to my question. Does PeopleSoft support access via a web services API or anything similar, and does that sound like the right direction for me to take?

  • Where’s my MD.050?

    - by Dave Burke
    A question that I’m sometimes asked is “where’s my MD.050 in OUM?” For those not familiar with an MD.050, it serves the purpose of being a Functional Design Document (FDD) in one of Oracle’s legacy Methods. Functional Design Documents have existed for many years with their primary purpose being to describe the functional aspects of one or more components of an IT system, typically, a Custom Extension of some sort. So why don’t we have a direct replacement for the MD.050/FDD in OUM? In simple terms, the disadvantage of the MD.050/FDD approach is that it tends to lead practitioners into “Design mode” too early in the process. Whereas OUM encourages more emphasis on gathering, and describing the functional requirements of a system ahead of the formal Analysis and Design process. So that just means more work up front for the Business Analyst or Functional Consultants right? Well no…..the design of a solution, particularly when it involves a complex custom extension, does not necessarily take longer just because you put more thought into the functional requirements. In fact, one could argue the complete opposite, in that by putting more emphasis on clearly understanding the nuances of functionality requirements early in the process, then the overall time and cost incurred during the Analysis to Design process should be less. In short, as your understanding of requirements matures over time, it is far easier (and more cost effective) to update a document or a diagram, than to change lines of code. So how does that translate into Tasks and Work Products in OUM? Let us assume you have reached a point on a project where a Custom Extension is needed. One of the first things you should consider doing is creating a Use Case, and remember, a Use Case could be as simple as a few lines of text reflecting a “User Story”, or it could be what Cockburn1 describes a “fully dressed Use Case”. It is worth mentioned at this point the highly scalable nature of OUM in the sense that “documents” should not be produced just because that is the way we have always done things. Some projects may well be predicated upon a base of electronic documents, whilst other projects may take a much more Agile approach to describing functional requirements; through “User Stories” perhaps. In any event, it is quite common for a Custom Extension to involve the creation of several “components”, i.e. some new screens, an interface, a report etc. Therefore several Use Cases might be required, which in turn can then be assembled into a Use Case Package. Once you have the Use Cases attributed to an appropriate (fit-for-purpose) level of detail, and assembled into a Package, you can now create an Analysis Model for the Package. An Analysis Model is conceptual in nature, and depending on the solution being developing, would involve the creation of one or more diagrams (i.e. Sequence Diagrams, Collaboration Diagrams etc.) which collectively describe the Data, Behavior and Use Interface requirements of the solution. If required, the various elements of the Analysis Model may be indexed via an Analysis Specification. For Custom Extension projects that follow a pure Object Orientated approach, then the Analysis Model will naturally support the development of the Design Model without any further artifacts. However, for projects that are transitioning to this approach, then the various elements of the Analysis Model may be represented within the Analysis Specification. If we now return to the original question of “Where’s my MD.050”. The full answer would be: Capture the functional requirements within a Use Case Group related Use Cases into a Package Create an Analysis Model for each Package Consider creating an Analysis Specification (AN.100) as a index to each Analysis Model artifact An alternative answer for a relatively simple Custom Extension would be: Capture the functional requirements within a Use Case Optionally, group related Use Cases into a Package Create an Analysis Specification (AN.100) for each package 1 Cockburn, A, 2000, Writing Effective Use Case, Addison-Wesley Professional; Edition 1

  • Suggestions for connecting .NET WPF GUI with Java SE Server

    - by Sam Goldberg
    BACKGROUND We are building a Java (SE) trading application which will be monitoring market data and sending trade messages based on the market data, and also on user defined configuration parameters. We are planning to provide the user with a thin client, built in .NET (WPF) for managing the parameters, controlling the server behavior, and viewing the current state of the trading. The client doesn't need real-time updates; it will instead update the view once every few seconds (or whatever interval is configured by the user). The client has about 6 different operations it needs to perform with the server, for example: CRUD with configuration parameters query subset of the data receive updates of current positions from server It is possible that most of the different operations (except for receiving data) are just different flavors of managing the configuration parameters, but it's too early in our analysis for us to be sure. To connect the client with the server, we have been considering using: SOAP Web Service RESTful service building a custom TCP/IP based API (text or xml) (least preferred - but we use this approach with other applications we have) As best as I understand, pros and cons of the different web service flavors are: SOAP pro: totally automated in .NET (and Java), modifying server side interface require no code changes in communication layer, just running refresh on Web Service reference to regenerate the classes. con: more overhead in the communication layer sending more text, etc. We're not using J2EE container so maybe doesn't work so well with J2SE REST pro: lighter weight, less data. Has good .NET and Java support. (I don't have any real experience with this, so don't know what other benefits it has.) con: client will not be automatically aware if there are any new operations or properties added (?), so communication layer needs to be updated by developer if server interface changes. con: (both approaches) Server cannot really push updates to the client at regular intervals (?) (However, we won't mind if client polls the server to get updates.) QUESTION What are your opinions on the above options or suggestions for other ways to connect the 2 parts? (Ideally, we don't want to put much work into the communication layer, because it's not the significant part of the application so the more off-the-shelf and automated the better.)
