  • Unit 2 File Concepts and File Structure
    UNIT 2 FILE CONCEPTS AND FILE STRUCTURE Structure 2.0 Objectives 2.1 Introduction 2.2 File Organisation 2.2.1 Sequential File Organisation 2.2.2 Indexed Sequential File 2.3 Random Access File Organisation 2.4 Multi-key File Organisation 2.4.1 Multilist File Organisation 2.4.2 Inverted File Organisation 2.5 Summary 2.6 Answers to Self Check Exercises 2.7 Keywords 2.8 References and Further Reading 2.0 OBJECTIVES In the preceding Unit of this block you have learnt about the Database Concepts and various types of databases and database models. You have seen that the files are main ingredient of databases. In this Unit you will learn the concepts of files in the computer environment and also how such files are organised. After the completion of this unit, you will be able to: define what is file organisation and discuss its different types; understand various file organisation techniques; and discuss various types of indexes used in file organisation. 2.1 INTRODUCTION Generally speaking, a file consists of a collection of records. A key element in file management is concerned with the ways in which the records themselves are organised inside the file, since this affects system performances heavily as far as record finding and access are concerned. Here, by “organisation”, we refer to the logical arrangement of the records in a file (their ordering or, more generally, the presence of ``closeness’’ relations between them based on their content), and not to the physical layout of the file as stored on a storage media.
