Data model: OODBMS vs. RDBMS
For this coursework two kinds of data models can be used. The object oriented data model, Object Oriented Database Management System(OODBMS), or the relational data model, Relational Database Management System(RDBMS). The differences between these two models and the data model to be used are described in this chapter. 1.1
Enumeration of some specifications of OODBMS and RDBMS
RDBMS have been around for more than 20 years, OODBMS are relatively new;
RDBMS can handle >10.000.000.000 records, OODBMS up to 10.000.000.
OODBM is good for storing complex descriptions (e.g., a plant schematic), RDMSs appropriate for simple, “flat” data.
RDBMS control the DB market (>90%), OODBMS own
