Repository

What is a repository?

A repository is a central location where data is stored. It can be data related to system requirements, policies, processes, software, projects, platforms, or employees of an organization. A repository serves as a directory used to manage a variety of data, sometimes including the management of different file versions. Repositories can support both software development and enterprise management.

In most cases, the basis of a repository is a database that can be stored locally on a hard disk or centrally on a server. In addition, there is a so-called data dictionary (data catalog), which contains representation forms, object definitions and relationships between individual data objects. The data catalog does not contain data records to be stored, but information about these data, i.e. metadata. Before physical data can be stored, the underlying data model must define a logical and conceptual framework. These schemas determine the structure of the database and how the data is modeled.
