Using Data Express

The easiest way to learn about Data Express is to complete a few simple tasks. This guide takes you through configuring Data Builder, loading metadata into the Data Express Knowledge Base, using Data Masking to implement masking rules on a small amount of data, using Data Subset Extraction to create a simple subset of data, and finally using Data Subset Extraction twice more to create subsets of data using referential integrity. Please note that some of the subsetting examples also mask data, showing that Data Express can do both functions in one method invocation.

The three Data Express modules (Data Builder, Data Masking, and Data Subset Extraction), and the ODBC Extension contain all the tools you need to perform these tasks.

Machine IDs and Company Codes

A Machine ID and Company code pair is essentially an identifier for your Data Express working environment or workspace. The Machine ID is the higher-level identifier, while the Company code must be identified by a Machine ID. You can create a new Machine ID and a new Company code for each test environment, or you can create new Company codes under a single Machine ID as needed for each test environment you want to create.

Note: A single machine ID can correspond to numerous company codes. A new company code can be created only if an existing machine ID is first selected.

Sample Data

Data Express includes sample XDB tables for the Data Express Knowledge Base and a corresponding XDB source database called TUTORIAL , which is used throughout the exercises in this tutorial. The database and its sample tables are installed automatically during product installation.
