A web and document databases (WDDB) is a system to manage efficiently local documents and semantic connection to remote databases. WDDB integrates search engine, query treatment and document management and provide a powerful mechanism to guide the access of information sources distributed all over the world. One WDDB system includes a local document database, a web connector, and a web recogniz...

We argue that a fully object-oriented database management system is a very suitable basis of every modern CASE environment. We describe how the features provided by an OODBMS are exploited to build a CASE tool or environment. We discuss especially problems concerning inter-document consistency constraints and multi-user support. We nally sketch the features which are still missing in OODBMSs.

Cloud storage systems have seen a growing number of clients due to the fact that more and businesses governments are shifting away from in-house data servers seeking cost-effective ease-of-access solutions. However, security cloud is underestimated in current practice, which resulted many large-scale breaches. To change status quo, this paper presents design ShieldDB, an encrypted document data...

A key problem facing engineering companies is the capture, control and recall of product design information from design and manufacturing staff. A solution to the problem proposed in this paper is the integration of design schematic diagrams with all other design documentation into a system of product books. This system unifies the many editors and computer tools used by engineering and ancilla...

As XML becomes the standard for electronic data interchange, benchmarks are needed to provide the comparative performance analysis of XML management systems (XMLMS). Typically a benchmark should adhere to four criteria: relevance, portability, scalability and simplicity [1]. The data structure of a benchmark for XML must be complex enough to capture the characteristics of XML data representatio...
