Database Systems.Paul Beynon-Davies, Palgrave Macmillan ISBN ISBN abbr. International Standard Book Number ISBN International Standard Book Number ISBN n abbr (= International Standard Book Number) → ISBN m 1-4039-1601-2 The main aim of this work is to provide one readable text of essential core material for further education, higher education higher education Study beyond the level of secondary education. Institutions of higher education include not only colleges and universities but also professional schools in such fields as law, theology, medicine, business, music, and art. and commercial courses on database systems. The current volume is designed to form a consolidated, introductory text on modern database technology and the development of database systems. It is true that database systems hold a prominent place in most contemporary approaches to the development of information systems. It is this practical emphasis on the use of database systems for information systems work that distinguishes the current volume from other texts on the subject. This work therefore forms a companion volume to Information Systems: An Introduction to Informatics in Organisations (Beynon-Davies, 2002) and to e-Business (Beynon-Davies, 2003), also published by Palgrave Macmillan. The current version has been revised to reflect the successful style and organisation of the Information Systems text. The text is built from the author's experiences of consultancy in this area, as well as in running a number of academic and commercial courses on database technology and database development for several years. Two types of changes have been made to the third edition: presentational and content. In terms of presentation, the structure of the chapters has been re-organised and the parts re-sequenced to make for a better educational experience. The third edition has been expanded considerably. * The part on database system fundamentals has been extended with a number of chapters, particularly with a chapter defining the concept of data and a chapter considering the important place of database systems in the informatics infrastructure for electronic business * A new part has been added which extends the discussion on the SQL SQL in full Structured Query Language. Computer programming language used for retrieving records or parts of records in databases and performing various calculations before displaying the results. database sublanguage (database, language) sublanguage - One of the languages associated with a DBMS, for example a data-definition language or query language. * Chapters on the ORACLE DBMS (DataBase Management System) Software that controls the organization, storage, retrieval, security and integrity of data in a database. It accepts requests from the application and instructs the operating system to transfer the appropriate data. and the Microsoft Access A database program for Windows, available separately or included in the Microsoft Office suite. Access is programmable using Visual Basic for Applications (VBA). Access can read Paradox, dBASE and Btrieve files, and using ODBC, Microsoft SQL Server, SYBASE SQL Server and Oracle data. DBMS have been updated * New chapters have been included on the database development process and requirements elicitation * The part on trends has been reorganised around four chapters: distributed processing The first term used to describe the distribution of multiple computers throughout an organization in contrast to a centralized system. It started with the first minicomputers. Today, distributed processing is called "distributed computing." See also client/server. , distributed data, parallelism An overlapping of processing, input/output (I/O) or both. 1. parallelism - parallel processing. 2. (parallel) parallelism - The maximum number of independent subtasks in a given task at a given point in its execution. E.g. and complex data. This latter chapter now includes coverage of semi-structured data and XML XML in full Extensible Markup Language. Markup language developed to be a simplified and more structural version of SGML. It incorporates features of HTML (e.g., hypertext linking), but is designed to overcome some of HTML's limitations. * The chapter on database systems and the Web has been updated Many chapters have been updated since 2000, and the structure of a number of chapters changed to provide a more coherent presentation of key topics. The sequencing of parts has also changed in response to requests for a more natural flow of topics. The text is organised into ten parts: Fundamentals, Data Models, DBMS Interface, Database Development, Planning and Administration of database Systems, DBMS, DBMS--Kernel, DBMS--Standards and Commercial Systems, Trends in Database Technology. Applications of Database Systems. The presentation of the book is designed to be used within some structured learning activity. Each part of the book begins with a section summarising the key elements of the database systems domain considered, and each chapter is designed as a learning unit aimed at imparting a number of key concepts in the area of database systems. |
