b) Critically evaluate the advantages of database management systems Advantages of DBMS Data independence: - the separation of data structure of database from the application program that uses the data is called data independence in database management system; you can easily change the structure of database without modifying the application program. For example you can modify the size and data type of a data items ( fields of a database table).data independence is usually consider from two points
Privacy of Information Technologies to Protect Personal Data In a modern life, from the minute a person is born, a digital record is created. From that point on, the individual’s behavior is regularly tracked and information are collected about the typical parts of the person life such as when government collect data about our health, education and income, we hope that the data are used in good way. However, we always have concerned about our privacy. Liina Kamm did her research on the Information Security
