REST ASSURED! Data Warehouse™


Do you have confidence in the quality of your data warehouse application?

REST ASSURED! Data Warehouse™ is a complete solution specifically developed for testing Data Warehouse applications. Our proprietary solution gives you the assurance you need that your mission-critical application will always perform flawlessly.

Why is Testing a Crucial Step in Implementing a Data Warehouse Application?
Over the past few years, more and more companies have been looking at data warehousing technology as the preferred way to exploit enormous amounts of database information, and to support managerial decision-making.
Two key characteristics of Data Warehouse applications pose a complicated challenge for any organization contemplating a Data Warehouse initiative:
How can we be sure the enormous amount of data is accurate and reliable, especially when it comes from multiple systems with different data structures?

Choose a Comprehensive Testing Solution for Flawless Data Warehouse Performance
Once you appreciate that the value of your Data Warehouse application relies upon the accuracy and reliability of your data, you quickly come to realize that comprehensive testing focused on data accuracy is essential.

Test Levels of the Data Warehouse Tests
Our data warehouse tests cover both the sensitive process of data extraction from the legacy system and the load to the data warehouse, as well as the display of this information to the end user.

The main Tests Involved in Ensuring the Accuracy of a Data Warehouse Application:
• Single file extraction tests
•  Relations between tables
•  Historical data test
•  Test "live” and full data
•  Display and use data warehouse information

Rest assured in the accuracy and reliability of your data warehouse application when you use a proven methodology based on years of real-world experience.
Tesnet Group’s REST ASSURED! Data Warehouse™ solution is based upon our proprietary methodology that delivers consistently outstanding results. Our proven methodology relies on years of real time experience in complicated data warehouse testing projects like yours.

Methodology Highlights
Count on a Proven Data Warehouse Testing Methodology Based on Real-World Experience.

Tesnet Group’s REST ASSURED! Data Warehouse™ solution is based upon our proprietary methodology that delivers consistently outstanding results. Our proven methodology relies on years of real-world experience in complicated Data Warehouse testing projects. A comprehensive formula provides you with high quality software, shorter implementation time, and minimal risks.

REST ASSURED! Data Warehouse™ Methodology
Our tests for your data warehouse cover both the sensitive process of data extraction from the legacy system and the load to the data warehouse, as well as the display of this information to the end user.

Test levels of the Data Retrieval Process
 There are four levels in testing data extraction and ETL (extract, transform, and load) processes:
• Single file extraction tests, where we test the extraction of single files
• Testing the entire set of the ETL. extractions rules are defined and tested for each file
•  Initial extraction tests and delta data extraction tests
•  ETL transformation rules for transforming files to the final format of the data warehouse (a highly complicated process)
•  ETL load rules for the final load of data to the warehouse

Relations between tables
Here, we examine the reliability of relations between tables (data integrity) within the ETL load process. Our objective is to ensure that your data integrity is maintained in the data warehouse, regardless of the loading sequence of the processes within the ETL.

Historical data change test
A significant feature of your data warehouse is your ability to manage and present the history of all changes made to an entity (for example, the entire history of customer address changes). Because managing historical data and retrieving the correct picture of an entity, within a given time frame, has always been a vexing issue, we consider it a challenge and devote particular attention to all options. We thus focus our tests on the way history records are managed and presented.
 
Test "live” and full data
The test designs for the previously described processes have been based on creating data under "laboratory conditions” to examine maximum population possibilities with minimum test cases. These tests include extreme conditions as well various combinations of the data population.
However, we must also test your system to see whether it works properly with a massive data population. Furthermore, we take into account that the real population includes corrupted data or cases not handled by the rules.

Display and use of data warehouse information
To complete the test, we test the reports, queries, views, OLAP cubes, EIS tools, and other means of displaying and using the information in the data warehouse. These tests validate the correctness of the information provided to the end user. During this stage, and due to the high processing demands of displaying data warehouse information, we perform load testing in order to ensure adequate response time.

Integrative Testing Automation
Automated testing tools are an integral component of our REST ASSURED! Data Warehouse™ Methodology. Tesnet Group uses leading automated testing tools, and augments them with our proprietary SMART Functions™; a sophisticated set of utilities that allow us to maximize the power of market-ready tools, and accelerate the testing process while increasing effectiveness.
By combining automated testing tools with Tesnet Group’s SMART Functions™, you enjoy shorter implementation time and increased test coverage, while significantly reducing manpower involvement.
