B. Indexing
Indexes separate data structures that allow DBMS to locate
particular records in the file of the base table more quickly [4].
Small tables with a small data size usually do not pose much
performance issues for MYSQL. However, as tables start
growing, the performance with retrieving data records can get
very inefficient resulting in long waiting time. Fortunately,
indexing in the MYSQL helps in retrieving data records faster
and more efficiently. For example, a simple SQL statement
using indexing helps to retrieve and sort data faster is shown
below.
