# Properties overview

Derby lets you configure behavior or attributes of a system, a specific database, or a specific conglomerate (a table or index) through the use of properties.

Examples of behavior or attributes that you can configure are:

- Whether to authorize users
- Page size of tables and indexes
- Where and whether to create an error log
- Which databases in the system to boot

- Scope of properties
- Persistence of properties
- Precedence of properties
- Dynamic versus static properties
