Chapter 1 Introduction To Databases Pdf Databases Client Server Model Database: it is a collection of interrelated data. these can be stored in the form of tables. a database can be of any size and varying complexity. a database may be generated and manipulated manually or it may be computerized. A typical dbms has a layered architecture. the figure does not show the concurrency control and recovery components. this is one of several possible architectures; each system has its own variations. Database systems are composed of complex data structures. in order to make the system efficient in terms of retrieval of data, and reduce complexity in terms of usability of users, developers use abstraction. This lecture introduces the concepts of database systems and management, emphasizing the structure and design necessary for efficient data storage and retrieval.
