The Importance of Data-Bases in the Process of Knowledge Sharing Inside of an Eco-Bio-Economic Cluster

The term „database” refers to a structured collection of data, used to model aspects of reality in a way that allows useful information to be extracted. In order for the data resource to be well defined and documented, easily administered and interrogated, derives the need to use a proper database management system.
A Database Management System (DBMS) is an interface between users and the database and is designed to store data in an organized manner and to provide full software support for the development of databases IT-apps. A DBMS must ensure the minimizing the data processing cost, reduce response time, the IT apps flexibility and, of course the data protection. Within a cluster-type strategic alliance, an important part in the knowledge-sharing process returns to the database, which is organized in distinct areas of interest, using methods set by After Action Review, or SMART, or other methods organized under complex procedures. The Knowledge Economy Index Report represents an independent review of databases in different countries, based on innovation, creativity, increased production / sustainable consumption and exports.

Aspects of the design of distributed databases

Distributed data – data, processed by a system, can be distributed among several computers, but it is accessible from any of them.

A distributed database design problem is presented that involves the development of a global model, a fragmentation, and a data allocation. The student is given a conceptual entity-relationship model for the database and a description of the transactions and a generic network environment. A stepwise solution approach to this problem is shown, based on mean value assumptions about workload and service. A management system of a distributed database (SGBDD) is a software system that enables management and distributing BDD transparent to the user. A SGBDD consists of a single database which is decomposed into fragments, poassibly some fragments are multiplied, and each fragment or copy kept on one or more sites under the control of a local DBMS. Each site is capable of processing user queries in the local system, independently of the rest of the network, or is able to participate in the processing of data in other sites in the network. To say that a DBMS is distributed CLE should be less global demand.
