Both SQL Server express and MySQL are two of the Relational Database Systems (RDBMS) available today. Both are freely available and meant for running smaller or embedded databases, yet there are also significant differences between them.
Simple-Talk.com has published my very first article on their site. This article is introducing Change Data Capture – the new concept introduced in SQL Server 2008. Change Data Capture records INSERTs, UPDATEs, and DELETEs applied to SQL Server tables, and makes a record available of what changed, where, and when, in simple relational ‘change tables’ rather than in an esoteric chopped salad of XML. These change tables contain columns that reflect the column structure of the source table you have chosen to track, along with the metadata needed to understand the changes that have been made.
