The DBMS software is more like a wrapper around the physical database, which provides us with an easy-to-use interface to store, access and update data. Data is that resource, for which DBMS was designed. The motive behind the creation of DBMS was to store and utilise data. Metadata is data about the data.

A document database is a type of nonrelational database that is designed to store and query data as JSON-like documents. Document databases make it easier for developers to store and query data in a database by using the same document-model format they use in their application code. The document model works well with use cases such as catalogs, user profiles, and content management systems where each document is unique and evolves over time. Document databases enable flexible indexing, powerful ad hoc queries, and analytics over collections of documents. A document database is a great choice for content management applications such as blogs and video platforms.

A flat file database uses a simple structure and, unlike a relational database, cannot contain multiple tables and relations.

Applying varying limitations on user access or actions. The limitations placed on or removed from users can apply to objects such as schemas, tables, or rows or to resources such as time CPU, connect, or idle times.
