Advanced applications, the need for a new data model emerges due to the limitations of traditional relational database management systems (RDBMS). Key challenges include managing complex data types, executing new operations, and facilitating recursive queries. Such requirements highlight the 'impedance mismatch' often encountered in RDBMS, particularly as computer applications evolve. This document discusses the role of object-oriented programming languages in implementing recursive queries and addresses the necessity of object database management systems to effectively handle these complex demands.
