Automatically Creating UML Database Diagrams for SQL Server

SQL Server database developers seem reluctant to use diagrams when documenting their databases. It is probably because it has, in the past, been difficult to automatically draw precisely what you want, other than a vast Entity-relationship diagram. However, you can do it without buying any third-party tool, just using some existing Java-based open-source tools; and can even automate it entirely, using SQL and PowerShell. Read more...

SQL Server Security Audit Basics

SQL Server Server Audit has grown in functionality over the years but it can be tricky to maintain and use because it lacks centralization and analysis tools.

How do you script an enterprise-wide audit solution? How can you hope to analyse the log data you get? Feodor gets you started. Read more...

Whereas this has always been easy to do in PowerShell, it was always painful to do in C# or VB because it meant having to build your own MAML file. Michael completes his three-part series by summarising, in a wallchart, how to go about it. Read more...

There are some obvious advantages to having the Query Store, but what is the performance impact that it is likely to have on a busy OLTP database server? It is early days, of course and until we get more experience we have to rely on Microsoft's estimate of a performance impact of 3-5% on average. However, this will depend on a number of factors such as usage an the way it is configured. Enrico explores some of these factors in order to give a clearer picture of what you should expect.

The Practical Problems of Determining Equality and Equivalence in SQL

In theory, it is easy to determine whether data is equal to, greater than or lesser than a value. Real-world data types can be surprisingly tricky, even for gauging data equivalence. Because SQL cannot remain aloof from any application's data types, you need to be aware of the ways and pitfalls of individual datatypes and how you can test for equality, equivalence, similarity, identity and all that jazz.
