While, the Information Retrieval System (IR) is the activity of gathering information resources which related to information need from a collection of information resources. Usually, we use metadata or full-text indexing in order to make a search on data requires. Information Retrieval Systems are used to overcome what has been called as information overload. Many universities and public libraries use Information Retrieval System to provide access to books, journals and other documents. For instance, Web search engines such as Google, Yahoo and Bing, are the most visible IR applications. There are several functions that DBMS performed to make sure the integrity of the data and data consistency in the database such as data storage, retrieval and update, A user-Accessible catalogue, transactional support, concurrency control services, recovery services, Authorization services, support for data communication, integrity services, services to promote data independence and utility services. Meanwhile, an information retrieval process begins when a user enters a query into the system. Queries are formal statements of information needs, for example search strings in web search engines. In information retrieval a query does notShow MoreRelatedDatabase Management Systems953 Words   |  4 Pagesprescribed book Chapters 1 - 3: Chapter 5: Chapter 6: Chapter 7: Chapter 12: Chapter 14: Chapter 16: Revise as for Assignment 01 Entity relationship modelling Advanced data modelling Normalisation of database tables Transaction management and concurrency control Distributed database management systems Database connectivity and web development Question 1 What is a composite entity, and when is it used?
