Bedrock's model components use XML to import and export database structure as well as data. The definition of databases, their tables, and each tables' columns and records can be nested within each other and defined in a single XML file, or can they can be separated into different files. Using separate files is generally recommended for maintainability's sake, using one file per table definition, one file per database definition, and data exports grouped by table in separate files.

The following tags are used to define database properties and attributes.

Table definitions can contain both table schemas as well as corresponding data. For most cases, it is recommended that you do not combine table schema definitions with actual record data. The only exception being in cases where a particular table must include some initial data at the time of creation (i.e. an admin account record for a users table).
