Which types of database uses software written in small reusable chinks as elements within database files?

Databases that utilize software written in small reusable chunks as elements within database files are often referred to as object-oriented databases. These databases store data in the form of objects, which can encapsulate both data and behavior, allowing for more complex data representations. Additionally, some NoSQL databases, like document stores, can also leverage reusable components within their structure to enhance flexibility and scalability.
