system a database management system is the software system that allows users to define create and maintain a database and provides controlled access to the data. a database management system dbms is basically a collection of programs that enables users to store modify and extract information from a database as per the requirements. http ecomputernotes.com fundamental what is a database advantages and disadvantages of dbms ۳ traditional file storage method http ecomputernotes.com fundamental what is a database traditional file processing system the file storage method is a group of files storing data of an organization. ۴ important characteristics of file processing system each file is independent from one another. each file is called a flat file. each file contained and processed information for one specific function such as accounting or inventory. files are designed by using programs written in programming languages such as cobol c c . the physical implementation and access procedures are written into database application therefore physical changes resulted in intensive rework on the part of the programmer. as systems became more complex file processing systems offered little flexibility presented many limitations and were difficult to maintain. http ecomputernotes.com fundamental what is a database traditional file processing system ۵ limitations of the file processing system i file based approach ۱. separated and isolated data ۲. duplication of data ۳. data dependence ۴. difficulty in representing data from the user s view ۵. data inflexibility ۶. incompatible file formats ۷. data security ۸. transactional problems ۹. concurrency problems ۱ . poor data modeling of real world http ecomputernotes.com fundamental what is a database traditional file processing system ۶ components of the database system environment there are five major components in the database system environment hardware software data users procedures http ecomputernotes.com fundamental what is a database advantages and disadvantages of dbms ۷ components in the database system environment hardware the actual computer system used for keeping and accessing the database. software the actual dbms. data the most important component of dbms environment from the end users point of view http ecomputernotes.com fundamental what is a database advantages and disadvantages of dbms components in the database system environment users – individuals who can access or retrieve data on demand using the applications and interfaces provided by the dbms. the users can be naive users users who need not be aware of the presence of the database system or any other system supporting their usage. online users those who may communicate with the database directly via an online terminal or indirectly via a user interface and application program. application programmers those who are responsible for developing application programs or user interface. sophisticated users users who interact with the system without writing programs. instead they form their requests in database query language. data base administrator dba the person or group

a database advantages and disadvantages of dbms type of database systems on the basis of the number of users single user dbms multi user dbms on the basis of the site location centralized dbms parallel dbms distributed dbms client server dbms http ecomputernotes.com fundamental what is a database type of database system ۱ users single user dbms the database resides on one computer and is only accessed by one user at a time. this one user may design maintain and write database programs. multi user dbms the data are both integrated and shared. a database is integrated when the same information is not recorded in two places. http ecomputernotes.com fundamental what is a database type of database system ۱۱ site location the centralized database system consists of a single processor together with its associated data storage devices and other peripherals. parallel database system architecture consists of a multiple central processing units cpus and data storage disk in parallel. http ecomputernotes.com fundamental what is a database type of database system ۱۲ site location a logically interrelated collection of shared data physically distributed over a computer network is called a distributed database and the software system that permits the management of the distributed database and makes the distribution transparent to users is called a distributed dbms. client server architecture of database system has two logical components namely client and server. clients are generally personal computers or workstations whereas server is large workstations mini range computer system or a mainframe computer system. the applications and tools of dbms run on one or more client platforms while the dbms soft wares reside on the server. the server computer is caned backend and the client s computer is called front end. http ecomputernotes.com fundamental what is a database type of database system ۱۳ …
