Course Details

Dimensional modeling is a core of data modelling development and one of the methods to store the data for easy retrieval of the data from the database. A dimensional model consists of fact tables and lookup tables. Dimensions and hierarchies can be represented as lookup tables. Attributes are the non-key columns in the lookup tables. In designing data models for data warehouses, schema types used are Star Schema and Snowflake Schema. Dimensional data modeling training teaches how to Design the Dimensional Model in a proficient manner.

Dimensional Data Modeling Training Overview

Our training deliver modern perspective of developing data. The sessions cover characteristics of data model, normalization and entity relationships. The classes range from basic to advanced techniques over the spectrum of skills that we teach with workshops, exercises and homework.
