Abstract	The Software Information Base (SIB) [1] was developed at FORTH as a repository system for re-usable software components. Originally intended to support the development of very large software systems within the ESPRIT ITHACA project, it has since been adapted to other application domains and in its current version (known as the Semantic Index System) provides a general tool for documenting and indexing large collections of interrelated heterogeneous data such as engineering designs, museum collections, organograms, etc. The SIB consists of a knowledge-base component built upon the TELOS knowledge representation language [5] and a collection of user and application interfaces, among them a TELOS parser, a graphical browser, static analyzers for various common programming languages, an interface to relational DBMS, and others. Information is entered into the system either automatically, e.g. by loading it from a relational database or by static analysis of a program module, or manually by means of a forms-based entry facility. Once the data is in the system, the user may browse it using the graphical interface or run a set of certain pre-de ned queries against it. In this paper, we present the design of an ad-hoc query facility for the SIB, which allows the user to write queries in a high-level, SQL-style language and have the system execute them. Our goal was to build a query language that was close to existing relational DB languages, su ciently powerful to express fairly sophisticated queries, and easily optimizable. A rst version of the query language has now been speci ed, and implementation of the query processor is under way.
