Database refactoring

The Process of Database Refactoring: Strategies for Improving , A database refactoring is a simple change to a database schema that improves its design while retaining both its behavioral and informational semantics. A database refactoring is a small change to your database schema (the table structures, data itself, stored procedures, and triggers) which improves its design without changing its semantics. Database refactoring is a technique which supports evolutionary development processes.

How to test database schema changes

Database Testing: How to Regression Test a Relational Database, For database changes that do not require a schema change (e.g. testing different hardware or configuration settings) we can spin up a new SELECT * FROM sys.fn_trace_gettable (@file, DEFAULT); DECLARE @file varchar (255); SELECT @file = path FROM sys.traces WHERE is_default = 1; SELECT * FROM sys.fn_trace_gettable (@file, DEFAULT); As a result, you will get a resultset with all events captured by this trace that are stored in available files.

Heap: How to Test Database Changes the Right Way, Well, as I see it, it is a matter of combining what is already there. The scenario described above: Write a database migration; Apply the database To test this solution, we must create an SQL Server Audit that captures the group of object modification events. In our case it is: SCHEMA_OBJECT_CHANGE_GROUP; This group tracks create, alter, and drop events on schema and its objects like table, view, stored procedure, function, etc. Creating an SQL Server Audit

Changing Database schemas & unit tests, Today's post describes how to use Default Trace. Test Case. To demonstrate you the advantages and drawbacks of various database schema Our initial method for testing database changes was largely based around synthetic, isolated benchmarks. When testing out a new schema, we would copy a small amount of production data onto an isolated machine and run some example queries.

Database refactoring catalog

This catalog is organized into​ A database refactoring is a small change to your database schema which improves its design without changing its semantics. This catalog is organized into several categories of database refactoring: Structural. A change to the table structure of your database schema. Data quality. A change which improves and/or ensures the consistency and usage of the values stored within the database.

Catalog of Database Refactorings, A structural database refactoring changes the structure of a table, column or view so as to improve your database design without changing its semantics. Appendix A. Database Refactoring Catalog This appendix summarizes the database refactorings that I have discovered over the years as well as some refactorings identified by others (Sadalage 2003). It is important to have a catalog of refactorings such as this to provide a common language that agile DBAs and application developers can use when working together to evolve database schemas.

Catalog of Database Refactorings, A data quality database refactoring is a change which improves and/or ensures the consistency and usage of the values stored within the database so as to database refactoring reference catalog. It describes over 60 database refactorings, presenting data models overviewing each refactoring and the code to implement it.
