Merging of bibliographic data bases in the leader retrieval system.
Steven Alan Russell · 1983
.rhe LEADBR Document Retrieval System consists of two components, both of which are currentJ y programmed in Pascal. The retreival component, which is responsible for processing user queries and returning relevant documents, is well sui ted for the language. The connectivity component, which is responsible for producing internally stored information, consists of file sorts and merges. These applications are not Pascal oriented. Another problem with Pascal is that lack of standardization causes lack of portability. This project involved the programming of connectivity in 1974 ANSI COBOL and producing the documentation necessary for its implementation. Tile final product is a highly structured, highly portable, and easily maintained system which provides the input necessary for the retrieval component of LEADER. This paper contains descriptions of all the programs, plus instructions for the use of the LEADER retrieval files.
