Data-driven, Time-Driven and keyword-driven testing?

What is Data-driven, Time-Driven and keyword-driven testing? Where/when are they used? Thanks.

Data driven testing is used when we have to test a functionality for different data's.Usually we use a table where we store the data to used for testing and testing tool use that data sequentially or randomly for testing.

Data-driven testing involves testing multiple data with same script.The data-driven testing approach can be used with unit and functional testing. It is especially useful in scenarios that are too cumbersome to execute with manual testing, for example, when an application needs to be quickly supplied a large amount of input values.

Keyword driven testing separates the test creation process into two distinct stages: a Planning Stage, and an Implementation Stage.It is a very powerful tool helping organizations to do more automated testing earlier in the testing process and making it easier to maintain tests over time.
