System and Data processing. A paper by a student in Business Management at University College Wisdom
Aurel Kodra, a student in Bachelor 2nd year in Business Management at University College Wisdom (Albania), wrote this paper for the CSB Pilot Course.
Information processors deal with different tasks, based on the task environment and the space of problems that arise.
Information processing theory describes the problem-solving processes, the characteristics of the information systems that perform these processes, and the nature of the environment in which these processes operate.
An information processing system is a system that takes information (a finite state sequence) into one form and processes (transforms) this information into another form through an algorithmic process.
An information processing system consists of 4 main parts, or subsystems:
An object can be considered an information processor if it receives information from another object, and transforms that information before passing it on elsewhere. This term can be used to describe any change that occurs in the information life span.
Information processing is an input-output function, which connects two initial states with the final state of information. The link may be probabilistic or deterministic.
What is DBMS ?
DBMS is a set of programs that control the organization, placement of data and retrieval of data in the database. DBMSs are separate based on the data structure they contain. DBMS accepts data requests from an application and directs the operating system to transfer data. Questionnaires should be accessed in a way that adapts to the format of the applicable protocols. When using the DBMS, the information system can be easily changed as the information organization requirements change. New categories of data can be added to the database without disruption to the existing system. Database servers are dedicated computers that maintain it and can execute DBMS and related software. Usually these servers are computers with many processors, with abundant memory and independent arrays in the form of strings. The hardware part of the database starter, connected to one or more servers through a high-speed channel, is also used in high-volume transaction processing. DBMSs are at the heart of most database applications.
Relational DBMS in the 70s
Edgar Codd worked at IBM in San Jose, California, in one of the offices that were engaged in hard disk development. He was dissatisfied with Codasyl's navigation model, especially in the "search" part. In 1970, he marked a considerable number of notes explaining a new approach to database building. In these letters, he describes a new system of storing and working with data. Instead of storing the row in some kind of linked list. This system can be very inconvenient in working with extended databases. The relational model had a solution to this problem by dividing the data into normalized tables.
In 1998, database management was dedicated to creating new models in database management. The researchers realized that the old methods were becoming very complex and that they needed automatic management. Surajit Chaudhuri, Gerhard Weikum and Michael Stonebraker were the pioneers who grammatically influenced the approach to data management. They believed that database management needed more modular access and that they had too many unnecessary specifications for users. Since these changes are now more likely, the database is not limited to monolithic entities, so they created more flexibility in management. There are several ways in which database management has affected the field of technology. Mobile devices can store much more data than contact information, search engines can locate data on the World Wide Web (WWW). Online have become very popular in e-business. Consumers and businesses can make more secure payments through various websites.
