Stored Program Controlled Network: Data Base Administration System - Architecture and Data Base Design

The No. 2 Data Base Administration System (DBAS) administers data bases stored in Automatic Intercept Systems (AISS), Traffic Service Position Systems (TSPSS) and Billing Validation Applications (BVAS). This administration consists of providing an initial load of data, ongoing updates, audits, and various reports. In general, the No. 2 D B A S serves as the telephone company's (Bell operating and, possibly, independent telephone companies) interface to data stored in these aforementioned systems. 1.1 Transition from No. 1 DBAS to No. 2 DBAS The No. 2 D B A S supersedes the No. 1 D B A S (previously known as the File Access Subsystem, FAS) and subsumes the responsibilities of the No. 1 D B A S for administering data in the A I S . This is accomplished by retaining the application software used on the No. 1 DBAS, and 1779 running it on the No. 2 DBAS processor in timeshare with new software that was written to administer TSPS and BVA data bases. Retaining the original software to perform the AIS administration was less costly than writing a totally new set of programs for this purpose, even though modifications to the existing software were required. 1.2 Basic software architecture
