Data is a collection of known facts that can be recorded and that have implicit meanings. Comment Database Database is a collection of related data or operational data extracted from any firm or organization. In other words, a collection of organized data is called database. Comment DBMS (Database Management System) DBMS is a collection of programs that enables users to create, maintain, and manipulate a database. The DBMS is a general purpose software system that facilitates the process of defining, constructing, and manipulating database. Comment Database Systems A database system comprises a database of operational data, together with the processing functionality required to access and manage that data. The combination of the DBMS and the database is called database systems. Comment Database Catalog A database catalog contains complete description of the databases, database objects, database structure, details of users, and constraints etc. that are stored. Comment Program-data independence In traditional file processing, the structure of the data files is ‘hard-coded” into the programs. To change the structure of the data file, one or more programs that access that file, should be changed. The process of changing can introduce errors. In contrast to this more traditional approach, DBMS access stores the structure in a catalog, separating the DBMS programs and the data definition. Storing the data and programs separately is known as program-data independence. Comment User View The way in which the database appears to a particular user is called user view. Comment DBA (Database Administrator) DBA is a person who is responsible for authorizing access to the database, coordinating and monitoring its use, and acquiring software and hardware resources as needed. Comment End User End users are the people who want to access the database for different purposes like, querying, updating, and generating reports. Comment Canned Transactions Standardized queries and updates on the database using carefully programmed and tested programs. Comment Deductive Database System A deductive database system is a database system that supports the proof-theoretic view of a database, and ,in particular, is capable of deducing are inferring additional facts from the given facts in the extensional database by applying specified deductive anxious are rules of inference to those given facts. Comment Persistent object Object-Oriented database systems are compatible with programming languages such as c++ and JAVA. An object that is stored in such a way that it survives that termination of the DBMS program is persistent. Comment Meta Data Information about the data is called Meta data. The information stored in the catalog is called Meta data. The schema of a table is an example of Meta data. Comment Transaction processing application A transaction is a logical unit of database. The processing includes one or more database operations like, insertion, deletion, modification and retrieval. The database operations that form a transaction can either be embedded within an application program on they can be specified interactively via a high-level query language such as SQL.
