This book provides practitioners and IT professionals in companies with a compact reference work. It delivers well-founded information and quick access to answers to questions and tasks that arise in the daily use of DB2/2 on OS/2 servers in the network as well as in client/server environments. Furthermore, the book deals with practical application development and extensively covers SQL and the Query Manager. It is particularly aimed at practitioners and IT professionals in companies who already have experience with medium (e.g., AS/400) and large IT systems (e.g., ES/9000). Basic knowledge of the relational model and database products such as DB2 or SQL/DS is therefore assumed. The book is of particular interest to professionals who are involved in downsizing existing mainframe applications to OS/2 servers in the network.
