Data is the major source of functional information and is essential for strategic planning, performance monitoring, resource allocation and other management functions. Data audit is needed to combat data quality problems.

With the help of right software you can easily gain access and interrogate data maintained on computer. They enable you to access data records and deal effectively with bulk data. Advanced audit software helps you to examine records for preciseness, integrity, completeness, validity, continuity, density and uniqueness. In addition, you can also verify calculations, make computations, compare data on separate files, select and print audit samples along with summarizing and re-sequence of data.

Data cleansing refers to the process of discovering or rectification of corrupt or inaccurate records from a database. The purpose of data cleansing is to identify incomplete, inaccurate and irrelevant data which is either replaced, changed or removed. The errors detected in the data may be a result of various data dictionary definitions of similar entities in different stores or corrupted during transmission or storage.

The process of data cleansing involves following features:

1.Data audit: The data is audited with the use of statistical methods to discover errors and omissions.
2.Workflow specification: To find and remove any abnormality is performed by a sequence of operations on the data which is known as workflow. The process is quite significant in achieving the end product of high quality data.
3.Workflow execution: The workflow is performed after its description is finished and accuracy is verified.
4.Post processing and controlling: Once the cleansing workflow is executed the outcome is audited to ascertain accuracy of the results. The data that could not be rectified during workflow execution is corrected manually.

Data migration refers to the process of transferring data between storage types, formats or computer systems. They are quite beneficial to companies who upgrade to new computer systems. The data on the former system is mapped to the new system offering a design for data extraction and data loading. The design relates old data formats to the advanced formats and needs. Data cleansing is done to improve data quality, remove the information which is of no use and to retain the data that well matches the needs of the upgraded system.
