    • Data Security, and more…
  • 3. Database:
    • Is a structured collection of records or data that is stored in a computer system.
    • Usually contains software so that a person or program can use it to answer queries or extract desired information.
    • The term "database" refers to the collection of related records, and the software should be referred to as the database management system (DBMS).
  • 4. Database Management:
    • Is a computer software made for organizing, analyzing and modifying the information stored in a database.
    • It is a set of programs that helps in controlling the organization's storage and retrieval of data in a database.
    • It helps manage the design process and builds a bridge between the design chain and extended enterprise for optimal design and resource management.
  • 5. The Benefits :
    • Increase productivity through real-time component data and design re-use.
    • Consolidate parts, inventory and manufacturing requirements.
    • Decision support through integration with enterprise business systems applications.
    • Information systems can be changed easily according to the company's requirements.
  • 6. Examples of DBMS:
    • Oracle
    • Microsoft Access
    • Microsoft SQL server
    • Firebird
    • FileMaker
  • 7. MICROSOFT ACCESS SCREEN SHOTS:
  • 8. Examples of database applications:
    • computerized library systems
    • automated teller machines
    • flight reservation systems
    • computerized parts inventory systems
  • 9. Types of database management system models:
    • DISTRIBUTED DATABASE MODEL
    • NETWORK DATABASE MODEL
    • OBJECT ORIENTED DATABASE MODEL
    • HIERARICIAL DATABASE MODEL
    • RELATIONAL DATABASE MODEL
  • 10. 1-DISTRIBUTED DATABASE:
    • Many users can access the database at the same time without interfering each other.
    • Economical and can be modified, added or removed from the system easily.
  • 11. 2-NETWORK DATABASE:
    • The network model tends to store records with links to other records.
    • Most network databases tend to also include some form of hierarchical model.
    • Used when large organizations spread over wide geographical area.
  • 12. 3-OBJECT ORIENTED DATABASE:
    • 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).
    • Generally recommended when there is a business need for high performance processing on complex data.
  • 13. HIERARCHICAL DATABASE:
    • 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.
    • An example : -organization had records of employees in a table called “Employees” and another called “Children”
  • 14. RELATIONAL DATABASE:
    • 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”.
  • 15. Business Performance Management (BPM):
    • Is a set of processes that help organizations optimize their business performance.
    • It is a framework for organizing and analyzing business methodologies, processes and systems that drive business performance.
    • BPM helps businesses make efficient use of their financial, human, material and other resources.
  • 16. Data Security:
    • 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.
