ABSTRACT
This chapter focuses on the formatting and structuring of information through documents. It provides an overview of organizing and retrieving information, focusing first on the database and then on the document itself. The chapter considers some of the problems concerning documents: problems of definition and relationship, and of text analysis. It provides an examination of document markup, instructions facilitating the storage and reuse of electronic documents, and metadata for facilitating access to documents. It then became necessary to examine the optimum way to structure data or to develop data models to support specific applications. Relational databases use one type of database structure, which has been widely adopted in database systems. Knowledge-based text processing systems and expert systems use many forms of knowledge representation. Multimedia database management systems are being designed to manage such databases.
