Combined query language (CQL): an interactive query language with procedural features

Interactive query languages provide easy to use interfaces to database systems. However, they lack the power of the host languages to perform manipulations on data. This thesis presents an interactive query language Combined Query Language (CQL) that has some features of procedural languages. CQL allows users to interactively manipulate da tabases and perform calculations on data. CQL is a self contained interactive query language that com bines the computational power of a host language (like FORTRAN) with the convenience and flexibility of the common interactive query languages. Users of CQL would not have to use a host language for most of the database applications. CQL uses the low level data base management routines devel oped for another thesis.' * Robert Fabbio's masters thesis.
