Testing Methods and Tools for Data Extract and EDW Loading

Data Warehouses play a vital role in Big Data. Companies rely on Data Warehouses for collecting information on their business operations, markets, and client behavior to identify patterns, and collect the results to identify more business opportunities and operational improvements.

Typical Testing Methods -

The data in the data sources is validated directly in the Data Warehouse, The data is validated from the data sources through each step of the extract, including the final load in the Data Warehouse

Testing Tools for Data Extract and EDW Loading

SQL Server Integration Services (SSIS), Informatica PowerCenter, OpenText Integration Centre, Cognos Data Manager

Testing Methods and Tools for Big Data Analytics

Big Data Analytics refers to the process of collecting, organizing, and analyzing large sets of data to discover patterns and reporting useful information. Specific areas within analytics include Predictive Analytics, Enterprise Decision Management, Retail Analytics, Predictive Science, Credit Risk Analysis, and Fraud Analytics.

Testing Methods for Big Data Analytics

Validating the Dashboard Report Model, Checking the Source Record Count and Target Record Count, Authentication Testing, Data Level Security, Bursting the Reports, Buzz Matrix Validation, User Acceptance Criteria, Time Series Functions Validations, End-to-End Testing

Tools for Big Data Analytics

Apache Falcon - Falcon simplifies the development and management of data processing pipelines with a higher level of abstraction taking the complex coding out of data processing applications by providing out-of-the-box data management services.

Testing Methods and Tools for Performance Testing and Failover Testing

Identify response time, maximum online user data capacity size, and maximum processing capacity with Performance Testing. Failover Testing validates the recovery process and ensures data processing continues correctly when switched to other data nodes.

Testing Techniques for Performance and Failover Testing

Static/Default Installation, Backup/Restore, Data Replication, Rolling Installation

Testing Tools for Performance Testing and Failover Testing

SandStorm, JMeter, Nagios, Zabbix, Ganglia, JMX Utilities, AppDynamics, Jespen
