====== Object-Oriented Database (OOD) ======
[[dido:public:ra:xapend:xapend.a_glossary:start| Return to Glossary ]]

**Object-Oriented Databases (OODs)** store data models created by [[dido:public:ra:xapend:xapend.a_glossary:o:oop]] 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 tools, which require a table to be set with the information. Some may choose to use an Object-Relational Database (ORD), which is a combination of an[[dido:public:ra:xapend:xapend.a_glossary:o:oo]] and [[dido:public:ra:xapend:xapend.a_glossary:r:rdbms | Relational Database]]. Other similar types of database solutions that differ from object-orientated databases include document database tools, graph database tools, key-value store tools, and more. Many object-orientated database software is available at no cost and developers have many free database software options.

To qualify for inclusion in the Object-Oriented Database category, a product must:

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