Ruby on rails with existing database

Question

I am very new to rails, and from what I read and looked at in textbooks, it only helps me to create things from scratch, while creating new databases and models.

my company has a project management software system in the field of accounting and construction, which was recently stored in ms sql server.

how will I build models from the existing table structure. they do not need to remove updates. im looking for creating a remote web query tool.

thank.
