ColdFusion is a fabulous programming language, which can also work to connect queries to the database. To perform queries in the ColdFusion framework, a datasource is necessary to be constructed. It provides the connection b/w ColdFusion and database.

After having the perfect datasource, it is necessary to perform queries. To perform a basic query, <cfquery> is used in the ColdFusion framework. This tag opens the gate of a database connection, and you have to supply the correct datasource name.  

Authentication is necessary to perform the query operations in the database. It is given in the form of the username and password. Supplying these username and password can override the overall ColdFusion administrator.

If a website application has good amount of traffic, then it can affect the performance of the application anytime. It is a better alternative to cache some of your queries which are to be used by the developers again and again.

In the cached query, all the retrieved results are stored in memory. Whenever the first time the query is run, the results are stored in the memory itself. When another time the same query is run, ColdFusion calls the results from the memory.
