Distributed data processing
Distributed Data Processing (DDP)[1] was the term that IBM used for the IBM 8100 (1975) and its successor, the IBM 3790 (1979). Datamation described the 3790 in March 1979 as "less than successful."[2] [3]
DDP was used by IBM to refer to two environments:
Each pair included a Telecommunications Monitor and a Database system.[4] The layoring involved a message, containing information to form a transaction, which was then processed by an application program.[5]
Development tools such as Program Validation Services (PVS) were released by IBM to facilitate expansion.[6]
Use of "a number of small computers linked to a central computer"[1] permitted local and central processing, each optimized at what it could best do. Central systems, sometimes multi-processors, grew to handle the load.[7]
Lower case DDP
Hadoop[8] adds another term to the mix: File System.
Tools added for this use of ddp include new programming languages.
