A database is an organized collection of data that can be accessed electronically from a computer system. It is also known as a computer file. A database may be simple, or it may be complex and involve the use of modeling techniques. The development of a database can be formal or informal, but in either case, the end result is always the same: an organized collection of data. However, a database must be secure, and it must be easy to maintain.
A good data catalog helps data scientists understand the data before they start working on a query. In fact, a recent study by Forrester and Forbes revealed that 75% of data scientists hate the task of looking for data, which takes up 75% of their time. A good data catalog can make this process less stressful for data analysts. By creating a comprehensive catalog, a business analyst will spend less time finding data and more time working on solving a problem.

A good database should have active metadata. Active metadata helps users access and manage data from multiple sources. This makes building and maintaining data management applications more efficient. It helps organizations find and evaluate complex lineages across systems and use cases. A data dictionary can be very useful for a variety of data management applications. If the content of a data dictionary is rich and well-structured, it can help users understand its meaning. Therefore, active metadata can help business professionals make the most of the data they have.
