Working with UltraLite databases


UltraLite databases (.udb files) are relational databases. They contain the following objects:

The schema and schema file 

The database schema is a description of the database. It is the collection of tables, indexes, keys, and publications within the database, and all the relationships between them.

You do not alter the schema of an UltraLite database directly. Instead, you create a schema (.usm) file and upgrade the database schema from that file by calling a built-in UltraLite function in your application.

A schema file is also used in the initial creation of a database to specify the structure of the database.
