About Data Warehouse Test
This assessment provides a framework of roles and responsibility for big data engineers and Data Warehouse administrators that can be quickly applied to the current environment.
Data warehouse is a central repository of information that can be analyzed to make more informed decisions. Data flows into a data warehouse from transactional systems, relational databases, and other sources, typically on a regular cadence. It stores current and historical data for the entire business and feeds BI and analytics. Data warehouses use a database server to pull in data from an organization’s databases and have additional functionalities for data modelling, data lifecycle management, data source integration, and many more.
This test helps recruiters assess candidates proficient in Online Analytical Processing (OLAP) , a category of software that allows users to analyze information from multiple database systems at the same time. It is a technology that enables analysts to extract and view business data from different points of view.
Data Warehouse uses a multi-dimensional data model, a snowflake schema where dimension tables are broken down into sub dimensions which are commonly used for business intelligence and reporting in OLAP data warehouses.
