1.A database is designed, built, and populated with data for a specific purpose." It has anintended group of users and some preconceived applications in which these users are interested.
2. A database management system is a collection of programs that enables users to create andmaintain a database (Fig. 4-1). The DBMS is hence a general-purpose software system thatfacilitates the processes of a defining, constructing, and manipulating database for variousapplications. Defining a database involves specifying the types of data to be stored in the database,along with a detailed description of each type of data. Constructing the database is the process ofstoring the data itself on some storage medium that is controlled by the DBMS. Manipulating adatabase includes such functions as querying the database to retrieve specific data, updating thedatabase to reflect changes in the mini-world, and generating reports from the data.
3. Big data analysis requires a cloud-based solution- -a networked approach capable of keepingup with the accelerating volume and speed of data transmission. This means that clusters of serversand software such as Hadoop and enterprise control language (ECL), which help find hiddenmeaning in large amounts of data, are distributed throughout the cloud on high-bandwidth cables.Using the cloud-based approach, a Google marketing analyst may be sitting in Silicon Valleyinputting information requests, but the data is being processed simultaneously in Tokyo, Amsterdamand Austin, Texas.
4.The name cloud computing was inspired by the cloud symbol that is often used to represent theInternet in flow charts and diagrams. Clouds can be classified as public, private or hybrid.Businesses often use applications available in the public cloud; they also frequently create a privatecloud just for data and applications belonging to their company.
5. Mobile commerce is an effective and convenient way to deliver electronic commerce to consumers fromanywhere and at anytime. Realizing the advantages to be gained from mobile commerce, many major companies have begun to offer mobile commerce options for their customers.
6.Compared to an electronic commerce system, a mobile commerce system is much morecomplicated because components related to mobile computing have to be included.I The followingoutline gives a brief description of a typical procedure that is initiated by a request submitted by amobile user.
7.Office Automation (OA) is the application of computer and communications technology to improve the productivity of clerical and managerial office workers. In the mid-1950s, the term wasused as a synonym for almost any form of data processing, referring to the ways in whichbookkeeping tasks were automaled.
8. Graphics- - Information that, may be in the form of numbers and words, then keyed into acomputer and displayed on a screen in a graph, chart, table, or other visual form that makesit easier to understand.
9. Computer-base approaches to education can enhance almost all other forms of distance education.
