• How do you track third-party software licenses?

  - by emddudley

  How do you track licenses for third-party libraries that you use in your software? How did you vet the licenses? Sometimes licenses change or libraries switch licenses--how do you stay up to date? At the moment I've got an Excel spreadsheet with worksheets for third-party software, licenses, and the projects we use them on (organized like a relational database). It seems to work OK, but I think it will go out-of-date pretty quickly.

• How to Schedule Backups with SQL Server Express

  - by The Official Microsoft IIS Site

  Microsoft’s SQL Server Express is a fantastic product for anyone needing a relational database on a limited budget. By limited budget I’m talking free. Yes SQL Server Express is free but it comes with a few limitations such as only utilizing 1 GB of RAM, databases are limited to 10 GB, and it does not include SQL Profiler. For low volume sites that do not need enterprise level capabilities, this is a compelling solution. Here is a complete SQL Server feature comparison of all the SQL Server...(read more)

• Many-to-many relationships in pharmacology

  - by John Paul Cook

  When I was in my pharmacology class this morning, I realized that the instructor was presenting a classic relational database management system problem: the many-to-many relationship. He said that all of us in nursing school must know our drugs backwards and forwards. I know how to model that! There are so many things in both healthcare and higher education that could benefit from an appropriate application of technology. As a student, I'd like to be able to start with a drug, a disease, a name of...(read more)

• Slowly Changing Dimensions handling in PowerPivot (and BISM?)

  - by Marco Russo (SQLBI)

  During the PowerPivot Workshop in London we received many interesting questions and Alberto had the inspiration to write this nice post about Slowly Changing Dimensions handling in PowerPivot. It is interesting the consideration about SCD Type I attributes in a SCD Type II dimension – you can probably generate them in a more dynamic way in PowerPivot (thanks to Vertipaq and DAX) instead of relying on a relational table containing all the data you need, which usually requires a more complex ETL process....(read more)

• 24 Hours of PASS next week, pre-con preview style

  - by drsql

  I will be doing my Characteristics of a Great Relational Database , which is a session that I haven’t done since last PASS. When I was asked about doing this Summit Preview version of 24 hours of PASS, I decided that I would do this session, largely because it is kind of light and fun, but also because it is either going to be the basis of the end section of my pre-con at the summit or it is going to be the section of the pre-con we don’t get to because we are so involved in working out designs that...(read more)

• Stairway to T-SQL DML Level 5: The Mathematics of SQL: Part 2

  Joining tables is a crucial concept to understanding data relationships in a relational database. When you are working with your SQL Server data, you will often need to join tables to produce the results your application requires. Having a good understanding of set theory, and the mathematical operators available and how they are used to join tables will make it easier for you to retrieve the data you need from SQL Server.

• Wait Statistics in Microsoft SQL Server

  - by KKline

  When it comes to troubleshooting in relational databases, there's no better place to start than wait statistics. In a nutshell, a wait statistic is an internal counter that tells you how long the database spent waiting for a particular resource, activity, or process. Since wait statistics are categorized by type, one look will quickly tell the variety of problem that needs your attention, assuming you know meaning for Microsoft's lingo for each wait type....(read more)

• Look-up Tables in SQL

  Lookup tables can be a force for good in a relational database. Whereas the 'One True Lookup Table' remains a classic of bad database design, an auxiliary table that holds static data, and is used to lookup values, still has powerful magic. Joe Celko explains....

• A Tale of Identifiers

  Identifiers aren't locators, and they aren't pointers or links either. They are a logical concept in a relational database, and, unlike the more traditional methods of accessing data, don't derive from the way that data gets stored. Identifiers uniquely identify members of the set, and it should be possible to validate and verify them. Celko somehow involves watches and taxi cabs to illustrate the point.

• Manipulating XML Data in SQL Server

  When the average database developer is obliged to manipulate XML, either shredding it into relational format, or creating it from SQL, it is often done 'at arms length'. A shame, since effective use of techniques that go beyond the basics can save much code, "It really helped us isolate where we were experiencing a bottleneck"- John Q Martin, SQL Server DBA.

• What is occurring in the world of server-side technologies in regards to the mobile app boom?

  - by Akromyk

  With mobile technologies becoming increasingly popular what is happening on the server-side with most of these apps when they need to communicate with a back end? I'm used to the world of technology from 10 years ago when most resources were accessed by requesting a dynamic web page that behind the seen used a server-side language to get the information it needed from a relational database. Is this still the case, and if not, what are the big changes?

• Mimicking Network Databases in SQL

  Unlike the hierarchical database model, which created a tree structure in which to store data, the network model formed a generalized 'graph' structure that describes the relationships between the nodes. Nowadays, the relational model is used to solve the problems for which the network model was created, but the old 'network' solutions are still being implemented by programmers, even when they are less effective.

• Basics of SQL Server 2008 Locking

  Relational databases are designed for multiple simultaneous users, and Microsoft SQL Server is no different. However, supporting multiple users requires some form of concurrency control, which in SQL Server's case means transaction isolation and locking. Read on to learn how SQL Server 2008 implements locking.
