  • Web-based data generator

    - by John Paul Cook
    One of my coworkers told me about Mockaroo , a web-based data generator. I needed some test data for upcoming blog posts, so I decided to give it a try. It’s pretty good. I had to use Firefox because of problems running Mockaroo on Internet Explorer 11. Using the defaults except for changing the format to SQL, it generated output that looked something like the following. Mockaroo is so good that it generates fake data that could accidentally be real, such as email addresses. Consequently, I edited...(read more)

  • Best way of accessing data on different pages

    - by Gaz83
    I'm looking for a way to load data into properties/variables etc and have this information accessible to all the pages of my app. I want the information to be loaded via a background thread to keep UI thread free. Some of the pages will have various properties of their controls binding to these global properties. Here is what I tried. Created a static class. All pages could access the data but can't bind. Changed the static class to a Singleton and used DependencyProperty's. All pages could access data and binding worked fine but cross-threading issues when accessing via background threads. I have read in various places on this subject but haven't really come up with the best method yet for my situation.

  • Master Data Management - The Trend Towards Multi-Domain and Other Realities

    - by Mala Narasimharajan
    In my quest to keep my fingers on the pulse of MDM, I recently found a pretty interesting article.  The article was published in Information Week and provides some interesting statistics from a recent survey conducted by the analyst firm, The Information Difference.  Let's take a look: Of the 130 organizations surveyed, 53% have live operational MDM implementations 81% of those with live operational MDM implementations report broad success - a huge improvement over 2011's 54% 64% developed a business case prior to their MDM deployment, while a daring 32% went ahead without a business case.    The article goes on to talk about the shift in vendors from focusing on customer data and product information management to one that is oriented around multi-domain master data management as well as other realities around MDM.  Take a look at the article.

  • Importing Data From Excel Using SSIS - Part 1

    Recently while working on a project to import data from an Excel worksheet using SSIS, I realized that sometimes the SSIS Package failed even though when there were no changes in the structure/schema of the Excel worksheet. I investigated it and I noticed that the SSIS Package succeeded for some set of files, but for others it failed. I found that the structure/schema of the worksheet from both these sets of Excel files were the same, the data was the only difference. How come just changing the data can make an SSIS Package fail? What actually causes this failure? What can we do to fix it?

  • I need to get past my permissions to recover data

    - by adsmz
    Due to some mishaps, I am unable to boot into Kubuntu at all. However, my data is still on the hard drive. I managed to get one of the other two computers to which I have access to read the disk by booting into a liveCD session of kubuntu. The only storage medium to which I have access is a 30 GB data stick. Here's where the trouble starts: In music alone, I have to back up about 60 GB. Obviously this is going to have to be split into chunks and moved over to the second spare PC until I can reinstall Kubuntu on my laptop. All of the data that needs backed up is behind a permissions wall, so while I can view it, I can't interact with it directly. I know copying and moving through the terminal can get around this with sudo cp or sudo mv, but is there a way to first compress multiple folders in a single archive, then move it? (While we're on the subject, what compression method would be best for large volumes of music in MP3, WAV, and OGG format?)

  • How can I extract the original image stream from a System.Drawing.Bitmap object?

    - by skolima
    I am embedding images into my assembly using .resx files. Upon runtime, I need to save the images into standalone files, restoring the original content. How can I extract the original file stream from an System.Drawing.Bitmap instance? I know I can create a stream using Bitmap.Save(), but this transcodes (and in effect - inflates) the images, even when saving a PNG back as PNG. Or perhaps my mistake is reading them from Resource as Bitmap in the first place?

  • How to prevent leaving an Icon in System Tray on exit?

    - by Malfist
    My program puts an icon in the system tray because the user may minimize to it. However, if the application crashes, or I stop the app from running in VS it leaves the icon in it until I hover over it with the mouse. Sometimes I'll look down there and there will be 10 or so icons. I can I make sure the icon goes away?

  • What difference between Web Apps & Descktop app shoud one keep in mind to model the system right?

    - by simple
    Sometimes it seems like some architectural techniques are not for the Web application I am building and then I just go and code =(, Though I really want to make a habit to architect system before moving to the code, as when I just code I endup writing some useless components which then I rewrite =(, So can you just point out some differences between web apps and desktop ones ?

  • Software Architecture: Quality Attributes

    Quality is what all software engineers should strive for when building a new system or adding new functionality. Dictonary.com ambiguously defines quality as a grade of excellence. Unfortunately, quality must be defined within the context of a situation in that each engineer must extract quality attributes from a project’s requirements. Because quality is defined by project requirements the meaning of quality is constantly changing base on the project. Software architecture factors that indicate the relevance and effectiveness The relevance and effectiveness of architecture can vary based on the context in which it was conceived and the quality attributes that are required to meet. Typically when evaluating architecture for a specific system regarding relevance and effectiveness the following questions should be asked.   Architectural relevance and effectiveness questions: Does the architectural concept meet the needs of the system for which it was designed? Out of the competing architectures for a system, which one is the most suitable? If we look at the first question regarding meeting the needs of a system for which it was designed. A system that answers yes to this question must meet all of its quality goals. This means that it consistently meets or exceeds performance goals for the system. In addition, the system meets all the other required system attributers based on the systems requirements. The suitability of a system is based on several factors. In order for a project to be suitable the necessary resources must be available to complete the task. Standard Project Resources: Money Trained Staff Time Life cycle factors that affect the system and design The development life cycle used on a project can drastically affect how a system’s architecture is created as well as influence its design. In the case of using the software development life cycle (SDLC) each phase must be completed before the next can begin.  This waterfall approach does not allow for changes in a system’s architecture after that phase is completed. This can lead to major system issues when the architecture for the system is not as optimal because of missed quality attributes. This can occur when a project has poor requirements and makes misguided architectural decisions to name a few examples. Once the architectural phase is complete the concepts established in this phase must move on to the design phase that is bound to use the concepts and guidelines defined in the previous phase regardless of any missing quality attributes needed for the project. If any issues arise during this phase regarding the selected architectural concepts they cannot be corrected during the current project. This directly has an effect on the design of a system because the proper qualities required for the project where not used when the architectural concepts were approved. When this is identified nothing can be done to fix the architectural issues and system design must use the existing architectural concepts regardless of its missing quality properties because the architectural concepts for the project cannot be altered. The decisions made in the design phase then preceded to fall down to the implementation phase where the actual system is coded based on the approved architectural concepts established in the architecture phase regardless of its architectural quality. Conversely projects using more of an iterative or agile methodology to implement a system has more flexibility to correct architectural decisions based on missing quality attributes. This is due to each phase of the SDLC is executed more than once so any issues identified in architecture of a system can be corrected in the next architectural phase. Subsequently the corresponding changes will then be adjusted in the following design phase so that when the project is completed the optimal architectural and design decision are applied to the solution. Architecture factors that indicate functional suitability Systems that have function shortcomings do not have the proper functionality based on the project’s driving quality attributes. What this means in English is that the system does not live up to what is required of it by the stakeholders as identified by the missing quality attributes and requirements. One way to prevent functional shortcomings is to test the project’s architecture, design, and implementation against the project’s driving quality attributes to ensure that none of the attributes were missed in any of the phases. Another way to ensure a system has functional suitability is to certify that all its requirements are fully articulated so that there is no chance for misconceptions or misinterpretations by all stakeholders. This will help prevent any issues regarding interpreting the system requirements during the initial architectural concept phase, design phase and implementation phase. Consider the applicability of other architectural models When considering an architectural model for a project is also important to consider other alternative architectural models to ensure that the model that is selected will meet the systems required functionality and high quality attributes. Recently I can remember talking about a project that I was working on and a coworker suggested a different architectural approach that I had never considered. This new model will allow for the same functionally that is offered by the existing model but will allow for a higher quality project because it fulfills more quality attributes. It is always important to seek alternatives prior to committing to an architectural model. Factors used to identify high-risk components A high risk component can be defined as a component that fulfills 2 or more quality attributes for a system. An example of this can be seen in a web application that utilizes a remote database. One high-risk component in this system is the TCIP component because it allows for HTTP connections to handle by a web server and as well as allows for the server to also connect to a remote database server so that it can import data into the system. This component allows for the assurance of data quality attribute and the accessibility quality attribute because the system is available on the network. If for some reason the TCIP component was to fail the web application would fail on two quality attributes accessibility and data assurance in that the web site is not accessible and data cannot be update as needed. Summary As stated previously, quality is what all software engineers should strive for when building a new system or adding new functionality. The quality of a system can be directly determined by how closely it is implemented when compared to its desired quality attributes. One way to insure a higher quality system is to enforce that all project requirements are fully articulated so that no assumptions or misunderstandings can be made by any of the stakeholders. By doing this a system has a better chance of becoming a high quality system based on its quality attributes
