Datasets provide data values for Insertion, Substitution and Row-Internal Synchronization rules. The datasets associated with the columns defined in the rule indicate which type of data will be entered into the specified target table and column. A wide variety of datasets (see below) are available to provide a range of realistic looking data.

For example, a column containing customer last names could be "Masked" by implementing a Substitution rule on it using the Names, Surnames, Random dataset. When the Substitution rule is executed as part of the run of the masking set, random last names would be generated and substituted in for each real customer last name. Thus the true last name of the customer would be hidden (preserving privacy and security) but the remaining data would still be referentially relevant and usable as a test system.

A dataset is associated with the target tables column when the rule is created and can be changed at any time simply by editing the rule.

Datasets have options which provide further configuration information. Each dataset offers configuration options specific to its requirements. For example, the Dates, Random dataset offers the ability to set the starting and ending points of the date range.

Note: It is quite possible to add your own custom dataset to the Data Masker system. All that is required is to place a simple text file (with a special naming convention) in the datasets directory. Please see the User Defined Datasets help page for more information on how to build your own datasets.

The datasets are installed when the Data Masker software is installed. By default the datasets are stored in a directory named DataSets located below the Data Masker installation directory. The location of this directory can be changed through the use of the configuration options on the Misc. Setup Tab.

The Datasets

Listed below are the datasets currently available with the Data Masker software. More datasets are added all the time - and we are always interested in hearing new ideas. If you have a requirement which cannot be fulfilled by the datasets below please do let us know by emailing us at Support@DataMasker.com.
