ADABAS
Adabas, a contraction of “adaptable database system," is a database package that was developed by Software AG to run on IBM mainframes. It was launched in 1971 as a non-relational database. As of 2019, Adabas is marketed for use on a wider range of platforms, including Linux, Unix, and Windows. Adabas can store multiple data relationships in the same table. History Initially released by Software AG in 1971 on IBM mainframe systems using DOS/360, OS/MFT, or OS/MVT, Adabas is currently available on a range of enterprise systems, including BS2000, z/VSE, z/OS, Unix, Linux, and Microsoft Windows. Adabas is frequently used in conjunction with Software AG's programming language Natural; many applications that use Adabas as a database on the back end are developed with Natural. In 2016, Software AG announced that Adabas and Natural would be supported through the year 2050 and beyond. Adabas is one of the three major inverted list DBMS packages, the other two being Computer Corpor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural (4GL)
Adabas, a contraction of “adaptable database system," is a database package that was developed by Software AG to run on IBM mainframes. It was launched in 1971 as a NoSQL, non-relational database. As of 2019, Adabas is marketed for use on a wider range of platforms, including Linux, Unix, and Windows. Adabas can store multiple data relationships in the same table.

Model 204
Model 204 (M204) is a database management system for IBM and compatible mainframe computers developed and commercialized by Computer Corporation of America. It was announced in 1965, and first deployed in 1972. It incorporates a programming language and an environment for application development. Implemented in assembly language for IBM System/360 and its successors, M204 can deal with very large databases and transaction loads of 1000 TPS. Product description Model 204 relies on its own type of bitmap index, originally devised by Bill Mann, and combines the use of hash table, B-tree, and partitioned record list technologies to optimize speed and efficiency of database access. It has been described as "one of the three major inverted-list atabase systems... the other two being" ADABAS and ADR's Datacom/DB. Although M204 is a pre- SQL (and pre- relational) database product, it is possible to manually map the files of an M204 database to approximate SQL equivalents and provid ...
