IBM and Oracle Advantages and Disadvantages of the database Management Systems approach vs. File based Systems Approach Disadvantage of a database management system is that they generally don't do well in Binary Large Object storage (BLObs, or binary files like images), but that's easy enough to get around by using references to the file system or a different database. Also, some DBMSs are designed for this. The advantage of using a DBMS is that not reinventing the wheel and everything
[ 30% mark ] Database management system Information retrieval system DBMS is manages incoming data, organizes it, and provides ways for the data to be modified or extracted by users or other programs. Information retrieval system is activity of obtaining resources relevant to an information need from a collection of information resources. This process can be find through the passwords or keywords or query from the users. DBMS provide efficient and effectiveness in management of the database.
facilitate the creation and maintenance of a computerized database. Evolution of Database Management Systems The revolution of database management systems were began on mid-1960s. Before that data was stored as paper records. It contributes a lot of disadvantages. Because of that people used to search another way to store their important data more safely and easily. As a result of that file-based system was introduced. It is easier to handle data with file based systems than using paper records. File –
which can have serious consequences for an organization. The complexity of functionality makes the DBMS an extremely large piece of software, occupying many megabytes of disk space and requiring substantial amounts of memory to run efficiently. Typically, a File Based system is written for a specific application, such as invoicing. As result, performance is generally very good. However, the DBMS is written to be more general, to cater for many applications rather than just one. The effect is that
works well with linear data storage type, such as tape. • Model relates very well to natural hierarchies, such as assembly lines and workers' organizations in the society. • This also applies in the case of works by one-to-many relationship. Disadvantages of Hierarchical Data Model • They needed to re-stored data in different individuals. • The database can be very slow when searching for information on subpages. • We no longer use linear memory environments, such as tape, so that the advantage
information systems that supports the competitive position. A strategic information system can be any kind of information system that controls information technology to help an organization: • Gain a competitive advantage. • Reduce a competitive disadvantage. • Meet other strategic enterprise objectives. There are five basic competitive strategies that businesses can implement to face the threats of competitive forces: Cost Leadership Strategy: Which means that the organization
