The results of the inference process are visible as regular views, accessible through SQL. Furthermore, to process intensional knowledge, an inference engine is coupled with the RDBMS. The database becomes a complete source of knowledge, both extensional and intensional.

The clauses of Prolog code are decomposed and stored in the RDBMS founding reusable components of Logic Program. To express intensional knowledge the Prolog language syntax is used in the form of clauses. The technology tackles the above problems by introducing rule-based processing (intensional knowledge processing) to the database systems.
It also briefly presents a prototype system implementing the Jelly View technology called ReDaReS. satisfying specific constraints etc.) This paper covers a part of the Jelly View technology, which provides a new, practical methodology for knowledge decomposition, storage, and retrieval within RDBMS. In particular, the following two categories of problems are hard to solve: Traversal of Structurally Complex Data Structures (such as graphs, trees, terms, lists etc.) and Search for Admissible Solutions Under Specified Constraints (finding specific subsets of a given set, generation of structural solutions.

It is implemented to provide better security to the user's password within the Online Password Management System (OPMS) in order to protect the user's data within the database from hackers and other forms of unauthorized access.ĭata processing capabilities of Relational Database Management Systems are limited. The algorithm's complexity is increased by increasing the amount of diffusion (multiplicative additive block) in a single round. Increasing the size of the key from 128 bits to 512 bits will increase the complexity of the algorithm. In this paper, we propose and describe the new design and preliminary implementation of a more secure encryption algorithm based on IDEA, and it is named DS-IDEA. In addition, a new attack during round six of IDEA's operations has been detected. Having the largest number of weak keys is one of the drawbacks of IDEA. The fundamental design of the algorithm is using three different algebraic operations: bitwise Exclusive OR, multiplication modulo, and addition modulo. IDEA block cipher operates with 64-bit plain text block and 64-bit cipher text block, and a 128-bit key controls it. International Data Encryption Algorithm (IDEA) is one of the encryption algorithms that is widely used for security purpose. This paper addresses the relational database threats and security techniques considerations in relation to situations: threats, countermeasures (computer-based controls) and database security methods.
Therefore, most of the firms are taking account of possibility of threats as measures to their database systems. RDBMS refers to relational database management systems that are using a relational model that developed by the researcher Codd at IBM laboratory.ĭatabase protection means disallowing illegitimate users to access the database and its sensitive information whether intentional or accidental.

Such functions contain services plus privileges for authorization to keep legitimate users (authorized) to access the database. Therefore, they deploy systems or applications have functions, services, and tools for data maintenance and management packed into the so-called Relational Database Management System (RDBMS). Organizations must ensure its information and data be secured and confidential. Technology evolution has produced more powerful systems that relate to economic impacts in the recent decade. The history of database research backs to more than thirty years, in which created the concept of the relational database system that has become the most fundamental change for organizations strategy.
