Disadvantages of file system?
Traditional file processing system lacks from DBMS in many ways . Major Disadvantage of FPS are it do not maintains data security and integrity efficiently.
What is reduced program maintenance?
stored data can be changed frequently for variety of reasons, the system will provide modification to a data file without modifying the program and it also provides us way to reduce the maintenance of the program
Fully functional dependency?
A functional dependency X --> Y is full functional dependency if removal of any attribute 'k' from X means that the dependency does not hold any more.Full functional dependency is minimal in size (contain non-redundant data)In a relation R , attribute B of R is fully functionallydependent on an attribute or set of attributes A of R , if B is functionally dependent on A, but not functionally dependent on any proper subset of A.ORAàB is a fully functionally dependency, if removal of any attribute X from A would result into the cancellation of dependency. i.e. (A-{X})-->B does not hold.
What tell the computer how to perform the functions of loading storing and executing an application and how to transfer data?
_ tell the computer how to perform the functions of loading, storing, and executing an application program and how to transfer data.
How program stored?
Actually, you do not store information in any program. You store it in a file on a hard drive. The program is what lets you access the information. Usually, large amounts of data that can yield information is managed by a data base system.
What is data dependency?
It is like a dependent variable it is just a variable alone.
What is data dependency in data base?
In DBMS approach,Data files are managed by database management system,Storage details are hidden from user program,thus creating a level of abstraction ... SOMNATH CHOWDHURY MCA(Engineering) G.H.Raisoni College Of engineering Wagholi,Pune

What is data dependency in DBMS?
Data dependency in DBMS refers to the relationship between different data elements within a database. There are three main types: functional dependency (one attribute determines another), partial dependency (part of a composite key determines other attributes), and transitive dependency (dependency between non-key attributes). Understanding data dependencies is crucial for database normalization and maintaining data integrity.
Why would you need to convert a string to a numeric data type?
For example, to interpret user input; to read data from a text file or from some other program that produces the data as a string.For example, to interpret user input; to read data from a text file or from some other program that produces the data as a string.For example, to interpret user input; to read data from a text file or from some other program that produces the data as a string.For example, to interpret user input; to read data from a text file or from some other program that produces the data as a string.
Define system analysis and design SAD?
system analysis and design is a process in doing a program........ and there a step on how to do a program first you study the data , second is analyze the data or program, third is draw your data, fourth is coding the data, next is testing the data that you do,next is implication and the last is maintenance. :-) hehehe
Purpose of sysytem calls?
The purpose of a system call is to provide an interface by which an application program (running in userspace) can request action from the operating system kernel. A system call might, for example, be used to read data from a file or transmit data via a serial port.
Can you call a computing system a data processing system?
Yes - since the computer processes data contained in the program or input by the user.
Describe the purpose of normalizing data and also list out the dependencies involved in the process of normalization?
The purpose of normalizing data in DBMS is to reduce the data redundancy and increase the consistency of data. a) Partial dependency: non-prime attribute ( field) depends on other non-prime attributes b) Functional dependency c) Transitive dependency
What has the author Larry Burd written?
Larry Burd has written: 'A feasibility study of a program data base for North Dakota residents entering chemical dependency programs' -- subject(s): Alcoholism, Research, Alcoholics, Data processing
What are the uses of database program?
Database system can be defined as the collection of interrelated data. Uses of database system are that it maintains data security , data integrity, data can be easily accessed and shared too.
What are the problems with data dependency?
Data dependency in computer science can lead to performance issues as it may create bottlenecks and limit parallel processing capabilities. It can also increase the risk of errors and hinder the efficiency of multi-threaded or distributed systems. Additionally, data dependency can make it difficult to optimize code for speed and scalability.
