This paper describes the design of the Cipherbase system. Cipherbase is a full-fledged SQL database system that achieves high performance and high data confidentiality by storing and processing strongly encrypted data. The Cipherbase system incorporates customized trusted hardware, extending Microsoft’s SQL Server for efficient execution of queries using both secure hardware and commodity serve...

Typical Cloud database services guarantee high availability and scalability, but they rise many concerns about data confidentiality. Combining encryption with SQL operations is a promising approach although it is characterized by many open issues. Existing proposals, which are based on some trusted intermediate server, limit availability and scalability of original cloud database services. We p...

An Internet based Distributed Control System (DCS) is presented in this paper for monitoring real time data using ordinary web browser. Each DCS will be connected to the central server which will be the system web server. The proposed system is based on the three-tier client-server model. The application server is written in C#.Net. SQL database server 2005 is used for all the DCSs local databa...

DITSE (Distributed Transaction Services Environment) is a distributed heterogeneous multi-database system which provides SQL to allow users to transparently access multiple databases on different machines. It also provides OLTP (On-Line Transaction Processing) services which contribute to develop reliable distributed applications. DITSE follows the most popular commit protocol, two-phase commit...

Corrector is a client-server web application which provides immediate feedback to students during practice sessions by automatically validating the proposed answers. The teacher needs only focus on solving comprehension problems with clever explanations. Corrector is especially well fitted to help teaching SQL, the language used in relational database systems. Indeed, some questions admit many ...
