Stairway to Database Design Level 2: Domains, Constraints and Defaults

A clear understanding of SQL Data Types and domains is a fundamental requirement for the Database Developer, but it is not elementary. If you select the most appropriate data type, it can sidestep a variety of errors. Furthermore, if you then define the data domains as exactly as possible via constraints, you can catch a variety of those problems that would otherwise bedevil the work of the application programmer.  Read more...

Stairway to Database Design Level 1: Data Elements

Before you start to think about your database schema or tables, you need to consider your data: the type of data it is, the scale you use for values. It needs to be unique, precise and unambiguous. Then you need to name it in such a way that it can be generally understood. Joe Celko explains...  Read more...

Designing Databases for Rapid Resilience

As the volume of data increases, DBAs need to plan more actively for rapid restores in the event of failure. For this, the intelligent use of filegroups is important, particularly when the Enterprise Edition of SQL Server offers the hope of online restores. How, though, should you arrange your data on the different filegroups? What happenens if the primary filegroup gets corrupted? Why backup and restore indexes?  Read more...

Physical Database Design Consideration

There are lots of things to think about when you design a physical database. What data types should I use? What column is appropriate for the primary key? Are there particular indexes that I should use to improve performance? How should I implement data integrity rules? This list goes on and on. In this article Greg Larsen will be exploring different physical database design elements.  Read more...

Constraints and the Test-Driven Database

Bad data always seems to appear when, and where, one least expects it. Sam explains the great value of a defensive approach based on constraints to any team that is developing an application in which the data has to be exactly right, and where bad data could cause consequential severe financial damage. It is perhaps better seen as creating a test-driven database.  Read more...
