摘要：
The RElational Data Access System (REDAS) is a data retrieval software package designed to provide convenient access to a database containing real-time as well as more static types of data. It provides the applications programmer with a high-level interface to the system database. REDAS is implemented in the C programming language under the UNIX operating system. It was designed such that the application program and database interface is a high-level interpretive language implemented as postfix strings. Various operators are provided for manipulating several types of records, for performing relational operations, for string manipulation operations, and for arithmetic operations. The algorithms for accessing the database are implemented as part of the application level programs and are thus data dependent. In contrast, the interpreter and associated software are data independent and are portable to other applications.
