   Object-oriented databases store data models created by object-oriented programming language. Programmers can create, modify, and store object datasets within these databases. Object-oriented databases require a query language in order to retrieve the information stored inside. Often used by engineering companies and science laboratories, object-oriented databases can hold more complex data than [relational database](https://www.g2.com/categories/relational-databases) tools, which require a table to be set with the information. Some may choose to use a object-relational database, which is a combination of object-oriented and a relational database. Other similar types of database solutions that differ from object orientated databases include [document database](https://www.g2.com/categories/document-databases) tools, [graph database](https://www.g2.com/categories/graph-databases) tools, [key-value store](https://www.g2.com/categories/key-value-stores) tools and more. Many object-orientated database software are available at no cost and developers have many [free database software](https://learn.g2.com/free-database-software) options.

- Provide data storage
- Store the data in object-based data models
- Allow users to create, store, and modify object data models
