Dimension_Table

One of the set of companion tables to a fact table, contains the attributes that are used to constrain and group data when performing database queries. Tables that define calendar periods, for example, are good examples of dimension tables.

Aggregate_Data

Data that is the result of applying a process to combine data elements. The data may be taken either collectively or in summary form. For example, in a daily sales report, invoice totals and summary totals from invoices are aggregate data, whereas the individual items that are sold are atomic data.

In a Star Schema, one large central table that typically contains one or more numerical measures or facts, such as Calls Handled, Total Time on Inbound, Dollars Sold, and so on.
A database table that consists of the measurements, metrics, or facts of a business process. It is often located at the center of a star schema, surrounded by dimension tables. Revenue tables often are categorized as fact tables.

Star_Schema

The common term for the dimensional database model, because of its characteristic star-like structure. Dimensional modeling is a database-design technique that is used for data warehouses and data marts. Every dimensional model is composed of one large central table that is called a fact table , and a set of smaller tables that surround it and are called dimension tables . Fact tables typically contain one or more numerical measures or facts, such as Calls Handled , Total Time on Inbound , Dollars Sold , and so on. By contrast, dimension tables most often contain descriptive attributes, such as Agent Name , Queue Name , Time Period , and so on.
