Chapter 7. Temporal Tables

Databases that serve business applications often support temporal data. For example, suppose a contract with a supplier is valid for a limited time only. It can be valid from a specific point in time onward, or it can be valid for a specific time interval—from a starting time point to an ending time point. In addition, on many occasions, you need to audit all changes in one or more tables. You might also need to be able to show the state in a specific point in time, or all changes made to a table in a specific period of time. From a data integrity perspective, you might need to implement many additional temporal-specific constraints.

This chapter introduces temporal problems, deals with manual solutions, shows out-of-the-box solutions in SQL Server 2016, and deals with the following topics:

  • Defining temporal data

  • Using temporal data in SQL Server before version 2016

  • System-versioned tables in SQL Server 2016

  • What kind of temporal support is still missing in SQL Server...
