Basics terms of Database Systems understanding:
Data: Data is the raw material from which useful information is derived. Data is a collection of facts which is unorganized but can be made organized into useful information. Data can be defined in many ways. Information science defines data as unprocessed information. In computer science, data is anything in a form suitable for use with a computer. Data is often distinguished from programs. A program is a set of instructions that detail a task for the computer to perform. In this sense, data is thus everything that is not program code.
Information: Information is data that have been organized and communicated in a coherent and meaningful manner. Data that have been processed in such a way so as to increase the knowledge of the person who uses the data is known as information. Data is converted into information, and the information is converted into knowledge. Knowledge; information evaluated and organized so that it can be used purposefully.
Meta Data: Data that describe the properties of other data is known as Metadata
Meta Data = data about data
Database: A database is a collection of information that is organized so that it can easily be accessed, managed, and updated. In one view, databases can be classified according to types of content: bibliographic, full-text, numeric, and images.
DBMS: The database management system (DBMS), is a computer software program that is designed as the means of managing all databases that are currently installed on a system hard drive or network. DBMS is a collection of interrelated data and a set of programs to access those data. Data management is a discipline that focuses on the proper generation, storage and retrieval of data. Different types of database management systems exist, with some of them designed for the oversight and proper control of databases that are configured for specific purposes. In database management system (DBMS), data files are the files that store the database information, whereas other files, such as index files and data dictionaries, store administrative information, known as metadata.
Knowledge: Knowledge is the body of information and facts about a specific subject. Knowledge implies familiarity, awareness, and understanding of information as it applies to an environment. A key characteristic of knowledge is that “new” knowledge can be derived from “old” knowledge.
Database System: Database system is a system to achieve an organized, store a large number of dynamically associated data, facilitate for multi-user access to computer hardware, software, and data, that it is a computer system with database technology:
• Data constitute the building blocks of information.
• Information is produced by processing data.
• Information is used to reveal the meaning of data.
• Accurate, relevant and timely information is the key to good decision making.
• Good decision making is the key to organizational survival in a global environment.
