What is MultiProgramming and MultiProcessing - Advantages, Disadvantages

Multi Programming VS Multi ProcessingWhen two or more processors share common memory and communicate with each other, it is called multiprocessing. Multiprocessing refers to the use of two or more CPUs within a mainframe. The main objective of...

What are Data Processing Methods | Types of Data Processing Batch, Online, Real

C Preprocessor and Types of Preprocessor Directives

Storage Classes | Definition, Types of Storage Classes

A storage class refers to the scope of data in a program. Scope of data means the portion of the program in which the variable is valid (main() as well as sub programs) and lifetime of the variable.i.e., the length of time to which the variable retains its value.

Keys & Types of Keys in Database - Super, Candidate, Primary, Foreign etc

A key is an attribute or a set of attributes in a relation that identifies a tuple in a relation. The keys are defined in a table to access or sequence the stored data quickly and smoothly. They are also used to create relationship between different tables.

Anomalies - Definition, Types of Anamolies & Examples

Anomalies: Anomalies are problems that can occur in poorly planned, un-normalized databases where all the data is stored in one table (a flat-file database).

Normalization & Different Normal Forms (NF)

Normalization is the process of splitting a relation (table) into sub relations or sub tables. Normalization is used to avoid or eliminate the three types of anomalies (insertion, deletion and update anomalies) which a database may suffer from.
