An identifying relationship is one where the child table cannot be uniquely identified without its parent. Typically this occurs where an intermediary table is created to resolve a many-to-many relationship. In such cases, the primary key is usually a composite key made up of the primary keys from the two original tables.

A non-identifying relationship : identified by a broken dashed line between tables. Create or drag and drop the tables that you wish to connect. Click on the appropriate tool for the type of relationship you wish to create. This creates a column in the table on the many side of the relationship.
