Today, databases are an integral part of most modern applications designed to store large amounts of data and to request from many users. To solve business problems in such conditions, databases are scaled, often horizontally on several physical... see more

A distributed system database performance is strongly related to the fragment allocation in the nodes of the network. An heuristic algorithm for redistributing the fragments is proposed. The algorithm uses the statistical information relative to the reque... see more

The paper analyzes the tasks that are performed during the processing of distributed data. The object of research is the process of automation of control in distributed systems and the organization of processing distributed data. During the study, a data ... see more

The advent of digital systems for the production and transmission of information decisively influences human progress and represents the future in any field of social life. In order to survive, organizations must correlate the objectives to the new trend ... see more

Databases represent a highly developed form of data organisation. The efficient use of databases by their beneficiaries is a permanent and stringent concern. The first part of the article presents a short development of the way data are organise... see more

This paper applies a model for distributed databases and transactions with a distinction between global and local correctness criteria. The global requirements per system are weaker than the local requirements per site. The paper presents an application w... see more

In this paper, two algorithms were introduced to describe two algorithms to describe and compare the applying of the proposed technique in the two types of the distributed database system. The First Proposed Algorithm is Homogeneous Distributed Clustering... see more

One of the algorithms in cryptography that can be used for school database security is the IDEA (International Data Encryption Algorithm) algorithm. The IDEA algorithm is one of the cryptographic algorithms that has various applications in secure data tra... see more
