how to trigger a glue crawler?

setting up a glue crawler job to read from an s3 bucket and create a glue catalog database. once the resource are created , how can i trigger it. can i hook it to s3 object creation ? also, can crawler detect relationship between the data and create the tables accordingly, similar to tables in a relational database, with foreign key to link between tables ? for example, one file has names of product and other files have product details.
