Directory properties
- Strongly typed and structured information, like RDBMS
- Object-oriented, hierarchical
- Multi-vendor interoperability due to..
- open standard access protocols
- core standard schema
- Extensible schema
- Highly distributable
- But no notion of “Join” or “report generation”, etc.
- Notion of “referential integrity” not in protocol - implementation-dependent
