  • SQL Saturday Birmingham #328 Database Design Precon In One Week

    - by drsql
    On September 22, I will be doing my "How to Design a Relational Database" pre-conference session in Birmingham, Alabama. You can see the abstract here if you are interested, and you can sign up there too, naturally. At just $100, which includes a free ebook copy of my database design book, it is a great bargain and I totally promise it will be a little over 7 hours of talking about and designing databases, which will certainly be better than what you do on a normal work day, even a Friday....(read more)

  • Does multiple files in SQL Server when using RAID help reduce conflicts in growth and file-locking?

    - by Dr Giles M
    I've been reading around and get the impression that if you are using RAID then using multiple SQL Server files within a filegroup won't yeild any more improvements, and the benefits are purely administrative (if you started to run out of space or wanted to partition off data into managable chunks for backups/balancing the data around your big server room). However, being a reasonably savvy software person, it's not unthinkable to hypothesise that, even for smaller databases that SQL Server will perform growth and locking operations (for writes) on a LOGICAL file basis, so even if you are using RAID, it seems to make sense to have multiple files in a file group to balance I/O, or does the time taken to reconstruct the data from distributed filegroups outweigh the benefits of reduced locking? I'm also aware that the behaviour and benefits may be different for tables/indeces/log. Is there a good site that distinguishes the benefits of multiple files when RAID is already in place?

  • Always use dtexec.exe to test performance of your dataflows. No exceptions.

    - by jamiet
    Earlier this evening I posted a blog post entitled Investigation: Can different combinations of components effect Dataflow performance? where I compared the performance of three different dataflows all working to the same overall goal. I wanted to make one last point related to the results but I thought it warranted a blog post all of its own. Here is a screenshot of one of the dataflows that I was testing: Pretty complicated I’m sure you’ll agree. Now, when I executed this dataflow in the test it was executing in ~19seconds however in that case I was executing using the command-line tool dtexec. I also tried executing inside the BIDS development environment and in that case it took much longer – 139seconds. That’s more than seven times as long. The point I want to make is very simple. If you are testing your dataflows for performance please use dtexec. Nothing else will suffice. @Jamiet

  • Survey: How much data do you work with?

    - by James Luetkehoelter
    Andy isn't the only one that can ask a survey question. This is something I really curious about because many of the answers or recommendations or rants in blogs are not universably applicable to every database - small databases must sometimes be treated differently, and uber databases are just a pain (and fun at the same time). So, how would you classify most of the databases you work with: 1) Up to 50GB 2) 50-500GB 3) 500GB - 2TB 4) DEAR GOD THAT"S TOO MUCH INFORMATION! Share this post: email it!...(read more)

  • Should we have a database independent SQL like query language in Django?

    - by Yugal Jindle
    Note : I know we have Django ORM already that keeps things database independent and converts to the database specific SQL queries. Once things starts getting complicated it is preferred to write raw SQL queries for better efficiency. When you write raw sql queries your code gets trapped with the database you are using. I also understand its important to use the full power of your database that can-not be achieved with the django orm alone. My Question : Until I use any database specific feature, why should one be trapped with the database. For instance : We have a query with multiple joins and we decided to write a raw sql query. Now, that makes my website postgres specific. Even when I have not used any postgres specific feature. I feel there should be some fake sql language which can translate to any database's sql query. Even Django's ORM can be built over it. So, that if you go out of ORM but not database specific - you can still remain database independent. I asked the same question to Jacob Kaplan Moss (In person) : He advised me to stay with the database that I like and endure its whole power, to which I agree. But my point was not that we should be database independent. My point is we should be database independent until we use a database specific feature. Please explain, why should be there a fake sql layer over the actual sql ?

  • Design patterns to avoiding breaking the SRP while performing heavy data logging

    - by Kazark
    A class that performs both computations and data logging seems to have at least two responsibilities. Given a system for which the specifications require heavy data logging, what kind of design patterns or architectural patterns can be used to avoid bloating all the classes with logging calls every time they compute something? The decorator pattern be used (e.g. Interpolator decorated to LoggingInterpolator), but it seems that would result in a situation hardly more desirable in which almost every major class would need to be decorated with logging.

    Reports. They're supposed to look nice. They're supposed to be a method by which people can get vital information into their heads. And that's obvious, right? So obvious that you're undoubtedly getting ready to close this tab and go find something better to do with your life. "Why is Adam wasting my time with this garbage?" Because apparently, it's not obvious. In the world of reporting we have a number of different types of reports: business reports, status reports, analytical reports, dashboards,...(read more)

  • Data Masking for Oracle E-Business Suite

    - by Troy Kitch
    E-Business Suite customers can now use Oracle Data Masking to obscure sensitive information in non-production environments. Many organizations are inadvertently exposed when copying sensitive or regulated production data into non-production database environments for development, quality assurance or outsourcing purposes. Due to weak security controls and unmonitored access, these non-production environments have increasingly become the target of cyber criminals. Learn more about the announcement here.

  • Defaults for Exporting Data in Oracle SQL Developer

    - by thatjeffsmith
    I was testing a reported bug in SQL Developer today – so the bug I was looking for wasn’t there (YES!) but I found a different one (NO!) – and I was getting frustrated by having to check the same boxes over and over again. What I wanted was INSERT STATEMENTS to the CLIPBOARD. Not what I want! I’m always doing the same thing, over and over again. And I never go to FILE – that’s too permanent for my type of work. I either want stuff to the clipboard or to the worksheet. Surely there’s a way to tell SQL Developer how to behave? Oh yeah, check the preferences So you can set the defaults for this dialog. Go to: Tools – Preferences – Database – Utilities – Export Now I will always start with ‘INSERT’ and ‘Clipboard’ – woohoo! Now, I can also go INTO the preferences for each of the different formats to save me a few more clicks. I prefer pointy hats (^) for my delimiters, don’t you? So, spend a few minutes and set each of these to what you’re normally doing and save yourself a bunch of time going forward.

  • How should I evaluate the Database Solution for Large Data Application

    - by GµårÐïåñ
    Background I have been tasked to write an application that will be a combination of document and inventory management in VB.net which will be used to store document images in TIFF, PDF, XPS, TXT, DOC, PPT and so on as binary data that can be retrieved for viewing, printing, and possible OCR to be searchable as well along with meta data such as sender, recipient, type of document, date, source, etc. So the table would probably be something like: DOC_NAME, DOC_DATE, NOTES, ... DOC_BINARY (where the actual document will be put inside) Help Please I need help with understanding how to evaluate my database options. What my concern is finding a database solution that will not become unstable due to size restrictions, records limitations and performance. Some of the options are MS_SQL, SQL Express, SQLite, mySQL, and Access. Now I can pretty much eliminate Access right off the bat as it is just too limiting and not scalable. I can further eliminate SQL Express because of the 2 GB limit and again scalability. So I believe that leaves me with MS_SQL, SQLite and mySQL (note, I am open to alternatives). And this is where I need help in understanding how to evaluate those databases. The goal is that the data is all in one place (a single file) that will make backup and portability easier. For small volume usage, pretty much any solution will hold for a while, but my goal is to think ahead and make sure its able to withstand heavy large volume usage as well. Another consideration is also the interoperability with .NET and stability of such code to avoid errors and memory leaks. How should I evaluate my database options for this scenario?

  • Oracle Database 12c By Example – SQL Developer and Multitenant

    - by thatjeffsmith
    As you may have heard, Oracle Database 12c is now available. In addition to the binaries and docs going out, we also published a few new Oracle By Example (OBE) chapters. You can find those links here on our product page. Do you know who found these, practically the minute they were published? An enterprising DBA-extraordinaire who was just happening to be presenting at the ODTUG KScope13 conference in New Orleans. He thought it would be a good idea to download the new software over a hotel WIFI, install and create a new multitenant database, watch a few OBEs, and then demo that live for his ‘SQL Developer for DBAs‘ session. Pretty crazy, right? Well, he did it, and I was there to watch. Way cool. You can listen to @leight0nn tell his story in his own words via this ODTUG interview with @oraclenered. In case you’re too giddy to sit through the video, I’ll give you a preview – he succesfully cloned a pluggable database in about a minute with only a couple of clicks using Oracle SQL Developer 3.2.20.09 while connected to a 12c database.

  • Google doesn't always show rich snippets when the site uses structured data [duplicate]

    - by Sam Se
    This question is an exact duplicate of: Google Structured Data [on hold] 1 answer I'm so tired of the Google structured data recipe. After some days, it loses the image and the extra information. Then I test it again, and it shows again. Some other days in the future it might go away even if it is still showing in test tool. What i can do? I tried with RDFa and schema.org microdata.

  • SQL Server 2000 need to prevent logons whilst performing a backup for a side by side migration

    - by pigeon
    I'm looking for a way to prevent logons from occurring in order to take a full backup of a Database to migrate from its current SQL Server 2000 instance to a new SQL 2005 instance. A friend of mine suggested running a script which would put the DB into a rollback state. Not being a DBA my DDL is very poor and running a script that I don't understand may not be the best idea. One option which might be easier is to simply detach and copy, to the new server. Any suggestions would be greatly appreciated.

  • A different interface for the Sql Server Reporting Service?

    - by AngryHacker
    I have a SQL Server 2005 SQL Reporting Services implementation. It seems that the only way to actually access the reports is for the users to use Internet Explorer. The web page uses an ActiveX control to do its printing (and probably other functions as well). Does SSRS have a different way to access its functionality via the web browser? Like maybe Java or HTML based? If so, how do I actually turn it on? The reason I am asking is because the security is being tightened and ActiveX controls will be banished, thus the users won't be able to print.

  • Q&amp;A: Will my favourite ORM Foo work with SQL Azure?

    - by Eric Nelson
    short answer: Quite probably, as SQL Azure is very similar to SQL Server longer answer: Object Relational Mappers (ORMs) that work with SQL Server are likely but not guaranteed to work with SQL Azure. The differences between the RDBMS versions are small – but may cause problems, for example in tools used to create the mapping between objects and tables or in generated SQL from the ORM which expects “certain things” :-) More specifically: ADO.NET Entity Framework / LINQ to Entities can be used with SQL Azure, but the Visual Studio designer does not currently work. You will need to point the designer at a version of your database running of SQL Server to create the mapping, then change the connection details to run against SQL Azure. LINQ to SQL has similar issues to ADO.NET Entity Framework above NHibernate can be used against SQL Azure DevExpress XPO supports SQL Azure from version 9.3 DataObjects.Net supports SQL Azure Open Access from Telerik works “seamlessly”  - their words not mine :-) The list above is by no means comprehensive – please leave a comment with details of other ORMs that work (or do not work) with SQL Azure.

  • A little on speaking and evaluations...

    - by AaronBertrand
    Buck Woody ( blog | twitter ) just published a great post on session evaluations , and a lot of his points hit home for me. The premise is that the evaluations are not really meant for the attendee or the event organizers, but so that the speaker can get better and make the next session better. In light of this, at least in my opinion, the existing evaluation forms (and the way attendees tend to fill them out) do not achieve this at all. It may be a little more work for events to generate a more...(read more)

    - by merrillaldrich
    A while ago I wrote a post, Visualize Disaster , prompted by a real incident we had at my office. Fortunately we came through it OK from a business point of view, but I took away an important lesson: it’s very easy, whether your organization and your team is savvy about disaster recovery or not, to have significant blind spots with regard to recovery in the face of some large, unexpected outage. We have very clear direction and decent budgets to work with, and the safety and recoverability of applications...(read more)

  • SQL language drawbacks, The Third Manifesto

    - by David Portabella
    Sometime ago I read about SQL language drawbacks (the basic language specification, not vendor specific), and one of the drawbacks was that the language does not allow to create a set of tuples that don't come from a table. For instance, SELECT firstName, lastName from people; this creates a set of tuples coming from the table people. Now, if I don't have this table people, and I want to return a constant, I'd need something like this to return a set of two tuples (this would not require to have a table): SELECT VALUES('james', 'dean'), ('tom', 'cruisse'); Why I would need that? Because of the same reasons that we can define constants (not only basic types, but objects and arrays also) in any advanced programming language. Workarounds, Yes, I could create a temporal table, fill the data, and SELECT from that table. This is a hack, to overcome the drawbacks of the poor SQL language. I think that I read about this somewhere in "The Third Manifesto", but I don't find the paragraph/example talking about this concrete drawback anymore. Do you know a reference about it?
