A database administrator (DBA) uses Db2, which is DBMS or database server, to create and use Db2 databases. The Db2 DBMS operates as the server to manage data in databases across a multiuser environment, enabling many concurrent users to access the same data simultaneously. The Db2 DBMS also...
Mainframe sites tend to use a hierarchical model when the datastructure(not data values) of the data needed for an application is relatively static. For example, a Bill of Material (BOM) database structure always has a high level assembly part number, and several levels of components with sub...
Db2 is a line of data management products from IBM. It includes a well-known relational database management system (RDMS) that IBM introduced in 1983 to run on its MVS (Multiple Virtual Storage)mainframeplatform. The name DB/2 originally referred to IBM's shift from a hierarchical database ...

In a scale-out environment,what is a benefit of running DB2 pureScale compared to other solutions?() A. Provides a highly available cluster of Power Systems enabling near linear scalability and disaster recovery across different...
Such systems ran primarily on mainframe computers. While RDBMSes also ran on mainframes -- IBM's Db2 being a pointed example -- much of their ascendance in the enterprise was in Unix midrange computer deployments. The RDBMS was a linchpin in the distributed architecture of client-server ...
The Microsoft Service for DRDA (Distributed Relational Database Architecture) is an Application Server (AS) that enables DRDA Application Requester (AR) clients, such as IBM DB2 for z/OS and DB2 for IBM i, to execute static SQL statements mapped to SQL Server stored procedures. The DRDA Servi...
