After initial index creation in a SQL Server database, everything is properly ordered, which means that the logical index page order perfectly matches the physical index page order within the datafile. This is the ideal scenario and it allows for maximum query performance. If the table contains data that never changes, the index will remain perfectly ordered.

In this article, the Document step of the Continuous Integration workflow will be described. After the Sync step is successfully completed, in this step, database documentation is created, using the latest changed database version.

In order to perform any continuous integration or delivery process, an important requirement – to be able to pull out the database (which you previously versioned in source control), automatically and repeatedly, to recreate the database in a QA environment at a click a button (or scheduled on a commit).

Apart from numerous factors, poor index maintenance can be a reason for decreased SQL Server performance. If a database contains tables with numerous entries, that get updated frequently, it is most likely that high index fragmentation will occur. For smaller indexes, high fragmentation does not necessarily degrade the performance of the queries that are run on a table. But for the larger tables, with indexes that consist of 1000 pages and more, fragmentation could cause noticeable performance issues. Luckily, performing index maintenance tasks on a regular basis can eliminate the risk of degrading performance significantly. The most effective ways for treating index fragmentation are reorganize and rebuild index operations.

Database status overview
Every database in a SQL Server environment has two basic states: full availability (online state) or full unavailability (offline state).

In the Understanding SQL Server database static data and how it fits into Database lifecycle management, we covered topics from the basics (what is the static data, why it is used), followed by the explanation of how to version control the static data, meaning how to initially commit, how to track changes and how to apply static data from SQL source control to a database.

When working with databases, availability and performance are of paramount importance. Performance of a database is based on multiple factors, key among them is being able to process queries quickly. That can be facilitated using indexes. Indexes are like the table of contents in a book, providing shortcuts to where the information is located. Otherwise, you would have to start reading the book from start until you find the information neededIt’s the same with databases, if it weren’t for indexes, for every query there would need to be an entire table scan.
