In
computer science, a data structure is a particular way of storing and
organizing data in a computer so that it can be used efficiently.
Different
kinds of data structures are suited to different kinds of applications, and
some are highly specialized to specific tasks. For example, B-trees are
particularly well-suited for implementation of databases, while compiler
implementations usually use hash tables to look up identifiers.
Data
structures provide a means to manage large amounts of data efficiently, such as
large databases and internet indexing services. Usually, efficient data
structures are a key to designing efficient algorithms. Some formal design
methods and programming languages emphasize data structures, rather than
algorithms, as the key organizing factor in software design. Storing and
retrieving can be carried out on data stored in both main memory and in
secondary memory.
Here i provide you some PPT lectures about Data Structure.
