Questions & Answers

Q: What are the main problems of a relational schema while designing a database?

The main problems include a lack of support for data type conversions, composite databases, multi-valued attributes, and derived attribute support.

Q: How does the introduction of object-based databases solve these problems?

Object-based databases support complex data types and multi-valued attributes, making database design easier for programmers and application designers.

Q: What is object-relational mapping?

Object-relational mapping is the process of mapping a relational schema to an object-based database, allowing programmers to embed SQL into native programming languages.

Q: How does object-relational mapping benefit programmers?

Object-relational mapping allows programmers to merge SQL with object-oriented features, eliminating the need for explicit SQL support in native programming languages.

Summary & Key Takeaways

• Object-based databases address the limitations of relational schema by offering support for data type conversions and complex attributes.

• By incorporating features from object-oriented programming languages, object-based databases simplify database design for programmers and application designers.

• Object-relational mapping allows programmers to embed SQL into native programming languages, making querying more efficient.
