Database organization

How the database is organized by LN is described here.

All application data that is used by LN is stored in database tables in the RDBMS. To keep the majority of the LN processing independent of the RDBMS, LN uses a data dictionary. The data dictionary includes domain, schema, and referential integrity information that is stored in a database independent manner.

Many tables are required, a convention is used for naming tables, columns within tables, and indexes to data within the tables.

The data dictionary and the naming conventions used by the LN database drivers to access data that is stored in the RDBMS is described. How LN data types are mapped to the database data types is also discussed.
