- I have done a paper evaluation of some of the commercial OODBMS vendors. I can't
- disclose the one selected. However, I would suggest a book that might provide some
- info ...
-
- Object Data Management by R.G.G. Cattell
-
- Also I have looked at these issues in my evaluation (not in any particular order).
- Data Model
- language interface (we needed C++). Dynamic typing ? etc.
- Persistence
- By type inheritance or allocation ?
- Operations
- - clustering
- - Version and Configuration Mgmt
- - Relationships
- - Referential Integrity
- - query support
- - collections / composite object support
- Concurrency Control & Lock Mgmt
- - is the granularity at the object level ?
- - how are deadlocks handled / detected (can they detect them accross
- databases
- Transaction Management
- - do they have long & short transactions
- - can they be nested
- Change Notification / Triggers
- Architecture
- - extensibility
- - ability to handle large amounts of data (scalability)
- - distributivity (accross hetrogenous machine architectures)
- - possible performance impacts
- Administration Utilities
- Authorization and Security
- Schema Evolution
- Performance
- - being a paper eval, we had to depend on published benchmarks / vendor
- supplied numbers and references
- Development Enviornment
- - could we use existing tools to develop code ?
- - how easy was it to migrate existing code to the ODB.
- References
- - this was quite informative as I got to speek with a number of existing users
- and people who had done extensive evaluations.
-
-
- Hope this helps.
