Dimensional Data Modeling Online Training

DIMENSIONAL DATA MODELING ONLINE TRAINING @ VIVANTA IT LABS
Dimensional Data Modeling Online Training course designed to make you an expertise in Dimensional Data Modeling and learn all that is required for how to create accurate data models for complex Business Intelligence solutions.



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 and
Dimensional Data Modeling Online Training Overview
Vivanta IT Labs aims to equip students with the structured and practise based knowledge in this area. Dimensional data modeling online training deliver modern perspective of developing data.
