Referential Integrity, Stored Procedures, and Triggers
Go Up to Using InterBase Databases
All relational databases have certain features in common that allow applications to store and manipulate data. InterBase also provides other database-specific, features that can prove useful for ensuring consistent relationships between the tables in a database. These include:
- Referential integrity. Referential integrity provides a mechanism to prevent master/detail relationships between tables from being broken. When the user attempts to delete a field in a master table which would result in orphaned detail records, referential integrity rules prevent the deletion or automatically delete the orphaned detail records.
- Stored procedures. Stored procedures are sets of SQL statements that are named and stored on a SQL server. Stored procedures usually perform common database-related tasks on the server, and return sets of records (datasets).
- Triggers. Triggers are sets of SQL statements that are automatically executed in response to a particular command.
