Database Management Approach The Database Management Approach consolidates data records in addition to objects into databases that can be accessed by many different application programs. This Approach Involves Three Basic Activities: 1. Updating in addition to Maintaining Common Databases 2. Sharing the Data in Common Databases 3. Providing an Inquiry/Response in addition to Reporting Capability The Use Of Database Software A software package that uses this approach is the Database Management System(DBMS), which serves as a software interface between users in addition to databases. The Four Major Uses of a DBMS Package are: 1. Database Development – Microsoft Access which allow end users so that easily develop the databases they need. 2. Database Interrogation – Provides a response so that questions from a database. 3. Database Maintenance – Updates continually so that reflect new business transactions in addition to other events. 4. Application Development – Develop custom application programs. Data Resource Management Benefits of Database Management: Limitations of Database Management: 1. Reduces duplication of data 1. Difficult in addition to expensive so that install 2. Easy so that obtain information 2. Greater storage required 3. Computer programming is simplified 3. Longer processing time 4. Security can be increased 4. Vulnerable so that errors
Types of Databases There are Six Major Types of Databases: 1. Operational Databases – Stores detailed data so that support the operations of the entire organization. Ex. Customer database, inventory database. 2. Analytical Databases – Stores data in addition to information extracted from selected operational in addition to external databases. 3. Data Warehouses – Stores data from current in addition to previous years that has been extracted from the various operational databases of an organization. 4. Distributed Databases – Stores copies or parts of databases. 5. External Databases – Stores a wealth of information from commercial online services, available so that companies alongside a fee. Possible Exam Questions 1. What are the advantages so that the database management approach? 2. Why is data resource management important so that an organization? What is a database? A database is an integrated collection of logically related records or objects. A database consolidates records previously stored in separate files into a common pool of data records that provides data in consideration of many applications.

Conclusion Data is a vital organizational resource that needs so that be managed like other important business assets. Most organizations could not survive or succeed without quality data about their internal operations in addition to external environment. This Stuff Called Data 1.
