Course Description
Overview
This Aster Data Basics course will cover the challenges of big data and the solutions that the Aster Data platform provides. The course will also discuss in detail how Aster Data tables are created, loaded and queried so users can become better prepared for large table joins and advanced analytics. This course will also discuss options to tuning queries with logical partitioning and columnar capabilities. This course will be 50% hand-on training and 50% lively discussion.Objectives
Upon completion of the Aster Data Basics course, students will be able to:
- Be familiar with Aster Data terms and understand the challenges that big data brings
- Be able to discuss the different options to creating Aster Data tables and the impact of their design on specific environments
- Understand how to design a fundamental Aster Data solution
- Have hands-on experience with querying Aster Data.
- Be able to discuss what to do and what not to do in order to query and design an Aster Data solution effectively
- Learn about Map Reduce and its functionality and strengths
- Gain enormous experience and knowledge in running a wide variety of Aster Data analytics
- Have the confidence necessary to be a solid performer on Aster Data
Audience
- Anyone involved in an Aster Data project or for any person who is or will soon be working with big data
- Managers, DBAs, developers and any IT or business professionals who are involved in managing, designing or querying an Aster Data system
