e-Government implementation and applications have gained a growing attention in the last decade. Countries seek to apply and extend the use of e-Government, and international organizations evaluate e-Government implementation and its impacts. The benefits of e-Government sound to be worthy while the costs of e-Government implementation sound to be costly. A clear implementation plan is a must to avoid...
Enterprises and cloud service providers face dramatic increase in the amount of data stored in private and public clouds. Thus, data storage costs are growing hastily because they use only one single high-performance storage tier for storing all cloud data. There’s considerable potential to reduce cloud costs by classifying data into active (hot) and inactive (cold). In the main-memory databases research,...
Data warehouse (DW) testing is a very critical stage in the DW development because decisions are made based on the information resulting from the DW. So, testing the quality of the resulting information will support the trustworthiness of the DW system. A number of approaches were made to describe how the testing process should take place in the DW environment. In this paper we will present briefly...
String matching algorithms play a vital & crucial role in many applications such as search engines, object identification, hand written recognition, name searching in large databases, data cleansing, and automatic spell checking. Many algorithms have been developed to measure string similarity but most of them designed mainly to handle Latin-based languages. In this paper, we propose a new algorithm...
Most of the current work on skyline queries mainly dealt with querying static query points over static data sets. With the advances in wireless communication, mobile computing, and positioning technologies, it has become possible to obtain and manage (model, index, query, etc.) the trajectories of moving objects in real life, and consequently the need for continuous skyline query processing has become...
Nowadays, rules make part of any software system including real-time applications and games, meanwhile an event can trigger many different rules according to the conditions controlling these rules. Although rules are core part to many kinds of systems, its maintenance and update are not easy without affecting the whole application. Hence, many systems have presented rules as a separate layer from...
