Answer:

It is a process that extracts information from internal and external databases, transforms it using a common set of enterprise definitions, and loads it into a data warehouse.

Explanation:

Extraction, transformation, and loading can be defined as a process that extracts information from internal and external databases, transforms it using a common set of enterprise definitions, and loads it into a data warehouse.

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.

A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.

Mazyrski [523]
