  1. 1. DATABASE MANAGEMENT SYSTEMS AND THEIR USES A presentation by: FERO Ltd. Co. Sponsored by SONY
  2. 2. Contents: <ul><li>Database </li></ul><ul><li>Database Management </li></ul><ul><li>Database Management benefits </li></ul><ul><li>Examples of DBMS </li></ul><ul><li>Types of database management system models </li></ul><ul><li>Data Security, and more… </li></ul>
  3. 3. Database: <ul><li>Is a structured collection of records or data that is stored in a computer system. </li></ul><ul><li>Usually contains software so that a person or program can use it to answer queries or extract desired information. </li></ul><ul><li>The term &quot;database&quot; refers to the collection of related records, and the software should be referred to as the database management system (DBMS). </li></ul>
  4. 4. Database Management: <ul><li>Is a computer software made for organizing, analyzing and modifying the information stored in a database. </li></ul><ul><li>It is a set of programs that helps in controlling the organization's storage and retrieval of data in a database. </li></ul><ul><li>It helps manage the design process and builds a bridge between the design chain and extended enterprise for optimal design and resource management. </li></ul>
  5. 5. The Benefits : <ul><li>Increase productivity through real-time component data and design re-use. </li></ul><ul><li>Consolidate parts, inventory and manufacturing requirements. </li></ul><ul><li>Decision support through integration with enterprise business systems applications. </li></ul><ul><li>Information systems can be changed easily according to the company's requirements. </li></ul>
  6. 6. Examples of DBMS: <ul><li>Oracle </li></ul><ul><li>Microsoft Access </li></ul><ul><li>Microsoft SQL server </li></ul><ul><li>Firebird </li></ul><ul><li>FileMaker </li></ul>
  8. 8. Examples of database applications: <ul><li>computerized library systems </li></ul><ul><li>automated teller machines </li></ul><ul><li>flight reservation systems </li></ul><ul><li>computerized parts inventory systems </li></ul>
  9. 9. Types of database management system models: <ul><li>DISTRIBUTED DATABASE MODEL </li></ul><ul><li>NETWORK DATABASE MODEL </li></ul><ul><li>OBJECT ORIENTED DATABASE MODEL </li></ul><ul><li>HIERARICIAL DATABASE MODEL </li></ul><ul><li>RELATIONAL DATABASE MODEL </li></ul>
  10. 10. 1-DISTRIBUTED DATABASE: <ul><li>Many users can access the database at the same time without interfering each other. </li></ul><ul><li>Economical and can be modified, added or removed from the system easily. </li></ul>
  11. 11. 2-NETWORK DATABASE: <ul><li>The network model tends to store records with links to other records. </li></ul><ul><li>Most network databases tend to also include some form of hierarchical model. </li></ul><ul><li>Used when large organizations spread over wide geographical area. </li></ul>
  12. 12. 3-OBJECT ORIENTED DATABASE: <ul><li>Information is represented in the form of objects as used in Object-Oriented programming. When database capabilities are combined with object programming language capabilities, the result is an object database management system (ODBMS). </li></ul><ul><li>Generally recommended when there is a business need for high performance processing on complex data. </li></ul>
  13. 13. HIERARCHICAL DATABASE: <ul><li>Data are organized into a tree-like structure. The structure allows repeating information using parent/child relationships :each parent can have many children but each child only has one parent. </li></ul><ul><li>An example : -organization had records of employees in a table called “Employees” and another called “Children” </li></ul>
  14. 14. RELATIONAL DATABASE: <ul><li>Users (or programs) request data from a relational database by sending it a query that is written in a special language, usually a dialect of “SQL”. </li></ul>
  15. 15. Business Performance Management (BPM): <ul><li>Is a set of processes that help organizations optimize their business performance. </li></ul><ul><li>It is a framework for organizing and analyzing business methodologies, processes and systems that drive business performance. </li></ul><ul><li>BPM helps businesses make efficient use of their financial, human, material and other resources. </li></ul>
  16. 16. Data Security: <ul><li>Is to ensure that data is kept safe from corruption and that access to it is suitably controlled. So help in ensure privacy. It also helps in protecting personal data. </li></ul>
