Data Dictionary

A database management system has an entity-relationship diagram, data dictionary, and data model as some of its key components, which are tools for the users who are managing the database. One of them is the data dictionary. The data dictionary can also be called metadata. By definition, metadata is a generic concept in the world of information and technology. An example of metadata could be meta-information about a media file or an image file, like author, location, last updated, size, etc. The contents of a data dictionary are names, attributes, and properties of main data elements which are captured during an experiment or stored in an information system, for example, databases. We can also call it a central repository of information about the main data.
