The Teradata product is referred to as a "data warehouse system" and stores and manages data. The data warehouses use a "shared nothing" architecture, which means that each server node has its own memory and processing power. Adding more servers and nodes increases the amount of data that can be stored. The database software sits on top of the servers and spreads the workload among them. Teradata sells applications and software to process different types of data. In 2010, Teradata added text analytics to track unstructured data, such as word processor documents, and semi-structured data, such as spreadsheets. Teradata's product can be used for business analysis. Data warehouses can track company data, such as sales, customer preferences, product placement, etc. Teradata has a supplier diversity program . "
