Classmate Post (Name: Olivia) –
Data dependence is when data description is built with the application program and if there is a change in the data there is a change in the program. Applications implemented in pre-relational database systems are datadependent, meaning that both the physical representation of the data and the methods of accessing it are built directly into the application code. This makes even the slightest change to the physical design of a database an extremely tough task. In other words, when data dependence is allowed in the system then data administration and management become a highly intricate and wearisome process.
Data Independence is when data description is not built within the application program. and if there is a change in the data, there is no need for a change in the program. In other words, the Data Independence property of DBMS helps you change the Database schema at one level of a database system without having to change the schema at the next/higher level. Data independence helps you to keep data separated from all programs that make use of it. In an OLTP database, data is stored in nonredundant tables that demand that every column of the table be rigorously related to its primary key alone and to no other tables. This ensures that information is available to all applications and analyses that use it, and it provides a mechanism for maintaining consistency and reliability across applications: a single source of each particular data element, a single version of the truth.
