What is a type tree?
A type tree describes the syntax, structure, and semantics of your data.
A type tree (.mtt) defines the entire contents of at least one input that you intend to map or one output you intend to map.
A type tree is the mechanism for defining each element of your data. Similar to a data dictionary, a type tree contains a collection of type definitions.

What is the use of properties window?

What are the common properties for the Item types?

What are the steps to create a *.mdq file?
A database/query file contains the definitions for one or more databases as well as queries, stored procedures, and other specifications that may contribute to the execution of a map. A database/query file is a file you create and save using the commands on the File menu in the Database Interface Designer. The result is a file with an extension of .mdq. This file name (including its path) appears in the title bar of the Database Interface Designer window when it is the selected file in the Navigator, indicating that it is the active .mdq file.

Is it necessary to stop an event server when new system/changes to a system is deployed?

If the Event Server is running when you create or update an .msl file, the change is not recognized and the file does not appear in the Event Server Monitor. You must restart the Event Server in order for changes to be recognized.
