NOMAD is a data management product that can easily access and combine data from a variety of sources including leading relational DBMS' such as DB2 for z/OS and z/VM, Teradata, and IDMS, as well as non-relational DBMS' such as IMS and IDMS. In addition, NOMAD can access QSAM sequential files and is, especially, efficient at accessing the complex hierarchical structures of VSAM files, typically, in use by banking, insurance, and other industries. Data from these sources can be accessed directly through a number of tools we provide.

NOMAD - a Relational and Hierarchical DBMS

Since NOMAD is itself a database management system that can be either relational or hierarchical, data extracted from the numerous heterogeneous systems mentioned above (databases and files) can be transformed, combined and loaded into a NOMAD database.  Utilizing built in functions, NOMAD can quickly aggregate or summarize the data where it can be used for further reporting and analysis.

Data stored in NOMAD databases can be in the form of a data mart, operational data store (ODS), or a data warehouse based on the requirements of the organization.  NOMAD allows users to combine data stored in a NOMAD data mart or warehouse with live or current data for comparison reporting.

Where a data warehouse implementation tends to serve the entire enterprise, a division or at least multiple departments, a data mart is a repository of data gathered from operational data and other sources that is designed to serve a particular group of users. The emphasis of a data mart is on meeting specific needs in terms of analysis, content, presentation, and ease-of-use. In addition, a data mart often uses aggregation or summarization of the data to enhance query performance.

NOMAD’s data management power stems from the breadth of its language and its unified architecture.  NOMAD’s comprehensive data definition language provides extensive support for data types, including arrays and time series, powerful defaults and flexible security and integrity constraints, including full support for rule-based referential integrity. Equally important, NOMAD’s unified architecture includes self contained procedural facilities that deliver everything expected in a traditional programming language.

Storing the data mart or data warehouse in a NOMAD database allows security at not only the database level but record and field level based on groups and user levels.

Implementing a data mart with NOMAD often can be achieved within a fraction of the time and money of traditional data mart or data warehouse approaches.

For years, NOMAD has been used to simplify large amounts of diverse production data that spans across the enterprise and creates something that is accessible and meaningful to the right audience for improved decision making.
