چکیده
Storing structured documents in object-oriented databases and fragmenting them according to their logical structure gives way to more expressive querying mechanisms, as compared to conventional document-management systems. At a rst stage, however, such an approach does not come out too good with regard to the performance of certain other basic operations. Thus, our database-application framework for document storage has been extended so that document-type-speci c semantics can be re ected with documents' database-internal representation. In this article, the dimensions of con gurability are described. Further, we say how the parameters are speci ed and how the non-trivial problems with regard to the realization have been solved. We discuss which (not-yet-existing) database features might have been advantageous in this context.

متن کاملThe Prospects of Publishing using Advanced Database Concepts
Publishing is a distributed process which is characterized by the cooperation of different experts. The approach of the Integrated Publication and Information Systems Institute (IPSI) to support electronic publishing is to build an integrated publication environment. The publication of electronic documents demands enhanced support from publishing tools and imposes new challenges on database tec...
متن کاملAdministering Structured Documents in Digital Libraries
In this chapter we argue that hyperdocuments administered by digital libraries have to be structured according to standardized storage and exchange formats in order to allow for the manipulation functionality required in digital library construction, maintenance and use. We demonstrate how SGML and its extension, HyTime, can play this structuring role, and how multimedia documents structured ac...
متن کاملAn OODBMS-IRS Coupling for Structured Documents
Requirements of modern Hypermedia Document Systems include support for structured documents and full DBMS and IRS functionality. An objective of DBMSs is to store and facilitate updates of highly structured and typed data. In conventional IRSs, however, documents are perceived as at. Uncertainty, on the other hand, is a principal notion in the IRS context. In order to combine the advantages of ...
متن کاملQuery Optimization for Structured Documents Based on Knowledge on the Document Type Definition
Declarative access mechanisms for structured document collections and for semi-structured data are becoming increasingly important. In this article, using a rule-based approach for query optimization and applying it to such queries, we deploy knowledge on the Document Type De nition (DTD) to formulate transformation rules for query-algebra terms. Speci cally, we look at rules that save navigati...
