data dependance mean the data is dependance upon application programme. when we change in data so also change in application program which we use
Data independance mean data is indpendant on applicaton programme or vice versa . if we change in data so there is no change in application programme
What else can I help you with?
What is program data dependence?
Program data dependence refers to the coupling of data stored in files and the specific programs required to update and maintain those files such that changes in programs require changes to the data. In a tradition file environment, any change in a software program could require a change in the data accessed by that program.
2.5 What is the difference between logical data independence and physical data independence?
The logical data independence is the ability to modify a logical schema without making external view or application program change. The physical data independence is the ability to modify a physical schema without making external view or application prrogram change.
What is the difference between information and information?
It seems like there is a typo in your question. However, if you meant to ask about the difference between "information" and "data," data refers to raw facts and statistics, while information is processed data that has meaning and context.
Why logical data independence is more difficult than physical data independence?
Logical data independence is considered more difficult than physical data independence because it involves changes to the conceptual schema and external schema, which are more closely tied to the way data is organized and viewed in the application. Physical data independence, on the other hand, deals with changes to the internal schema, which is more abstract and can be modified with less impact on the overall system.
Is it harder to achieve logical data independence or physical data independence?
It is generally considered more difficult to achieve logical data independence compared to physical data independence. Logical data independence involves separating the conceptual structure of the data from the physical storage aspects, which can be complex depending on the database design. Physical data independence primarily deals with shielding the application from changes in the storage structure, which is usually more straightforward to achieve.
What is program data dependence?
Program data dependence refers to the coupling of data stored in files and the specific programs required to update and maintain those files such that changes in programs require changes to the data. In a tradition file environment, any change in a software program could require a change in the data accessed by that program.

What is the difference between primary data and secondary data Don't make it complicated please?
The difference between primary data and secondary data is that primary data is the information from the original research.
Which one between logical and physical data independent is harder to achieve and why?
the logical data independence is hard to achieve because all the manipulation is belonging in logical data independence but in physical data independence only show the physical view .
What is temporal dependence?
Temporal dependence refers to the relationship between events or observations that occur over time. It indicates that the occurrence or value of one event is influenced by the occurrence or value of a previous event. In statistics and data analysis, understanding temporal dependence is important for modeling and predicting time-series data accurately.
