LN Database Organization

All application data 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 stored in a database-independent manner.

Many tables are required and a convention is available to name:

• Tables
• Columns in tables
• Indices to data in the tables.

We will describe the data dictionary and the naming conventions LN database drivers use to access data stored in the RDBMS. We also discuss how LN data types are mapped to Oracle data types.
