Different Types of Indexing Methods
Indexing methods in a database management system (DBMS) can be classified as dense or sparse indexing methods, depending on the number of index entries in the database. Let’s take a look at the differences between the two types of indexing methods:
Dense indexing and Sparse indexing are types of primary indexing. Now let’s take an overview of these terms:
Difference Between Dense Index and Sparse Index in DBMS
Indexing is a technique in DBMS that is used to optimize the performance of a database by reducing the number of disk access required. An index is a type of data structure. With the help of an index, we can locate and access data in database tables faster. The dense index and Sparse index are two different approaches to organizing and accessing data in the data structure. These are commonly used in databases and information retrieval systems.
