Efficient Retrieval of Structured Documents From Object-Relational Databases

چکیده
This paper proposes a new and efficient method to represent, store and retrieve structured documents from object-relational databases. Its main contribution consists of a codification scheme for document structures that assigns codes to documents as an additional attribute. Thus, retrieval conditions on the structure of documents can be evaluated by applying these codes, avoiding traversing object references. The paper also gives some clues to the construction of a repository of structured documents over objectrelational tables, so that query conditions regarding the contents, structure and metadata of documents are executed by the underlying database system.

Querying XML Documents
Web-based simulation environments will need to maintain a large collection of documents. Information about simulation models and results from multiple sites will need to be stored. This information should be held in a widely utilized and highly viewable format. The eXtensible Markup Language (XML) is a new standard that supports data exchange on the World-Wide Web. It is sophisticated enough, s...
متن کاملStorage and Retrieval of XML Documents Using Object-Relational Databases
This paper describes general storage and retrieval methods for XML documents using object-relational databases. The storage method decomposes tree structure of XML documents into nodes, and stores them in relational tables according to the node types. By using this method, being independent of DTDs or element types, any XML documents can be stored in databases. Also it is possible to utilize in...
متن کاملManaging XML documents in object-relational databases
XML becomes the standard for the representation of structured and semi-structured data on the Web. Relational and object-relational database systems are a well understood technique for managing and querying such large sets of structured data. In our approach, the nested-relations data model is the basic model for representing XML data in object-relational database systems. Using the partitioned...
متن کاملA DOM-Based Approach of Storage and Retrieval of XML Documents Using Relational Databases
This paper describes a novel approach of storage and retrieval of XML documents using relational databases. In this approach, an XML document is decomposed into nodes based on its tree structure, and stored into relational tables according to the nodes types. Our approach enables us to store XML documents using a fixed relational schema without any information about XML schema, and DTD. For the...
متن کاملAn Efficient Data Extraction and Storage Utility For XML Documents
In this paper, a mechanism to provide selective extraction of data objects from XML documents, the storage of these documents in an object-relational database, and retrieval and reconstruction of XML documents from extracted data objects is discussed. The motivation is provided by a need for a Workflow Process Repository in a Workflow Management System (WFMS) [6], namely METEOR WFMS, to store m...
