What is object-oriented database PDF?
Object-oriented databases (OOD) are database systems that can work with complex data objects – that is, objects that mirror those in object-oriented programming languages – as well as simple data objects.
What are object-oriented databases?
An object-oriented database (OOD) is a database system that can work with complex data objects — that is, objects that mirror those used in object-oriented programming languages. In object-oriented programming, everything is an object, and many objects are quite complex, having different properties and methods.
What is database Introduction to database?
A database is an organized collection of data, generally stored and accessed electronically from a computer system. It supports the storage and manipulation of data. In other words, databases are used by an organization as a method of storing, managing and retrieving information.

What is object database with example?
Object databases may be used for real-time applications whereby they can extend memory beyond the operating system’s own virtual memory limit. Examples of object-oriented databases are ObjectStore (www.ignitetech.com) and Versant Object Database (www.versant.com).
Why do we use object-oriented database?
Object databases are commonly used in applications that require high performance, calculations, and faster results. Some of the common applications that use object databases are real-time systems, architectural & engineering for 3D modeling, telecommunications, and scientific products, molecular science, and astronomy.
Why is object-oriented database important?
Object-oriented databases provide a number of advantages over relational databases like ease of extensibility, custom data models, provision for modelling complex data structures and faster access time.
