Chapter 1 Introduction To Databases Pdf Databases Computer Program 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. Relational databases a relational database consists of a number of 2 d tables. here is one: for each table, there is one row per record, technically known as a tuple. each record has a number of fields, technically known as attributes. Transaction: an execution of a db program key concept is transaction, which is an atomic sequence of database actions (reads writes). each transaction, executed completely, must leave the db in a consistent state if db is consistent when the transaction begins. A database is a collection of information that is organized so that it can be easily accessed, managed and updated. computer databases typically contain aggregations of data records or files, containing information about sales transactions or interactions with specific customers.
