How to build a tool to enter and access data on cloud

I am a web designer with no coding experience . I was offered a project. .. the client wants a "tool to put all his data(huge employee records) on cloud and to access it as needed " .My question is 1. What exactly such a tool is called ?
2. Can it be built without coding? Websites like joomla, etc. Can they be used somehow ? 3. Can coding be learnt simultaneously with the project? Sorry for the silly question.
