What is a Data Dictionary?

Data dictionary, referred to as meta-data, is a repository of data about data.

Metadata is information about each dataset or schema, such as a table, event file, or column. For example, the metadata related to the specific laptop you are using includes the model number, manufacturing details, compliance ID, and so on. Through these extended details — metadata — one can easily navigate through different laptop models and locate similar to yours in no time. 

In general, a database table looks like this:

Name EmailEmployee IDGender
Monika monika@yahoo.com1100F

And, its metadata looks like this:

Column NameDefinition Data typeRequired
Name This column refers to the first name of the employeeString Yes
EmailThis column refers to the personal email ID of the employees VarcharYes
Employee IDThis column refers to the unique ID that is given to every employee in the companyNumeric Yes
GenderThis column refers to the gender of the employeeStringNo

Database Note Taker is an open-source tool. It is easy to use, provides an intuitive platform solution to the data dictionary and documentation needs. Database Note Taker offers relevant databases for developers and concerned staff — in only HTML format — with the metadata stored in the SQL server.

  • Developer friendliness: While developing new databases, developers might make new database relation copies; this does not interfere with the actual project files, so they remain excluded from the real data dictionary. Moreover, database Notetaker is not limited to a particular database platform, making it an agile tool for developers working in different coding environments.
