• Virtual storage access method — (VSAM) is an IBM disk file storage access method, first used in the OS/VS2 operating system, later used throughout the Multiple Virtual Storage (MVS) architecture and now in z/OS. Originally a record oriented filesystem, VSAM comprises four data… …   Wikipedia

• Queued sequential access method — In IBM mainframe operating systems, a queued sequential access method (QSAM) is one of the access methods for files, or more properly data sets. QSAM files are unkeyed, with the records placed one after another, according to entry order. A… …   Wikipedia

• Basic direct access method — In IBM mainframe operating systems, basic direct access method (BDAM) is an access method to read and write data sets directly. In BDAM, the programmer has complete control of the organization of the file. Placement and retrieval is done by… …   Wikipedia
