A Document Management System Based on an OODB
نویسنده
چکیده
Efficient document management is extremely important as a tremendous volume of documents are produced and accessed by modern information systems. A document management system is described in this paper. The system stores SGML documents in an ObjectStore object-oriented database and is capable of storing, within one database, different types of documents by accommodating multiple DTDs. We create an object type for all DTDs and store each DTD as an object of that object type. We create an object type for each element definition in a DTD and store each element of an SGML document as an object. This database representation is advantageous to declarative query and fine-grained modification of documents. The system supports automatic creation of object types and insertion of documents into the database. Two different interfaces are provided for the user to retrieve, modify, and delete documents. The system supports declarative query of documents, which can be made with respect to their contents or

Bulk Loading into an OODB: A Performance Study
Object-oriented database (OODB) users bring with them large quantities of legacy data (megabytes and even gigabytes). In addition, scienti c OODB users continually generate new data. All this data must be loaded into the OODB. Every relational database system has a load utility, but most OODBs do not. The process of loading data into an OODB is complicated by inter-object references, or relatio...
متن کاملA Knowledge Based System Converting ER Model into an Object-Oriented Database Schema
In this paper, we discuss a knowledge based system, KERO, which implements a methodology converting an entity-relationship (ER) model into a structurally objectoriented database schema. A set of rules that can convert most semantic constructs of ER models into an OODB schema is discussed. Our method is an improved one which can properly convert many-to-many relationships with non-key attributes...

ÐObject-oriented database system (OODB) supports an object-oriented data model with the functionality of persistency and transaction semantics. In order to facilitate the use of OODB, the Object Database Management Group (ODMG) defined a standard for object database management system. On the other hand, the Object Management Group (OMG) defined the Common Object Request Broker Architecture (COR...

Keyword Spotting is a well-known method in document image retrieval. In this method, Search in document images is based on query word image. In this Paper, an approach for document image retrieval based on keyword spotting has been proposed. In proposed method, a framework using relevance feedback is presented. Relevance feedback, an interactive and efficient method is used in this paper to imp...

In this paper we present Document analysis and classification system to segment and classify contents of Arabic document images. This system includes preprocessing, document segmentation, feature extraction and document classification. A document image is enhanced in the preprocessing by removing noise, binarization, and detecting and correcting image skew. In document segmentation, an algorith...
