Course Introduction

This hands-on course provides the knowledge and skills needed to design and build a data warehouse using North America leading-edge products. The most important point is that you will gain practical Data warehousing and BI project experience working with SQLServer, and complete Microsoft BI solution including SSIS, SSRS and SSAS.

Your will learn How to:

    • Design and build comprehensive Data Warehousing, big data warehouse and data lake solutions
    • Implement special data modeling techniques and define metadata
    • Analyze business requirements
    • Develop a data model & generating a multidimensional database using Erwin.
    • Generate and maintain database objects such as Tables, Primary Key, Foreign Key, Unique Key, Indexes,

    Views, and Triggers etc. using Erwin.

    • Define Extraction, transformation and loading (ETL) process and use ETL tool – DataStage to load data into

    data warehouse

    • Develop comprehensive ETL project by using Microsoft SSIS  Develop Business Intelligence (BI)

    solutions with SSRS and SSAS.

    • Extend data mining by using Microsoft enterprise miner
    • Microsoft PowerBI data analysis
