Directory Service Implementation

Introduction

The Directory Service implemented here uses a set of reference tables in a relational database. Data access is by means of Java Database Connectivity (JDBC).

Use of SQL is restricted to standard SQL that is recognized by all major relational databases. But the implementation is only tested so far with an Oracle database.

The Database tables

The database tables and other objects for the directoryservice are the core of the directory system.

These tables are either the source tables or views to the source tables, or they are derived tables that are regularly updated from source data in the configuration database. This is completely automated with scripts and all tables remain functional during the update.
