The DBC 1012 Data Base Computer was introduced by Teradata Corporation in the early 1980s as a back end data base management system for mainframe computers. The DBC 1012 harnessed multiple Intel microprocessors, each with its own dedicated disk drive by interconnecting them with the YNET switching network in a massively parallel system. The DBC 1012 was designed to manage databases up to one Terabyte (1,000,000,000,000 characters) in size. The major components of the DBC 1012 architecture included :

• Mainframe Resident Software to manage users and transfer data
• Interface Processor (IFP) - the hardware connection between the mainframe and the DBC 1012
• YNET - a purpose built system interconnect that supported broadcast and sorting
• Access Module Processor (AMP) - the unit of parallelism: includes microprocessor, disk drive, file system, and database software
• System Console and Printer
• TEQUEL (TEradata QUEry Language) - an extension of SQL
