To answer this question, let's go through each option and understand what information is specified in the Connection tab of the DataLink window:
Option A) Database login - This option refers to the credentials required to log in to the database. It typically includes a username and password. The Connection tab in the DataLink window may indeed include fields to enter the database login information.
Option B) Database name - This option refers to the name of the database that you want to connect to. The Connection tab in the DataLink window may include a field to specify the database name.
Option C) Database type - This option refers to the specific type of database that you are connecting to, such as MySQL, Oracle, SQL Server, etc. The Connection tab in the DataLink window may have a dropdown or selection field to choose the appropriate database type.
Option D) Both a and b - This option is correct because the Connection tab in the DataLink window typically includes fields to specify both the database login information and the database name.
Option E) All of the above - This option is incorrect because the Connection tab in the DataLink window may not necessarily include the database type. The correct answer is option D, as it specifies that both the database login and the database name are specified in the Connection tab.
Therefore, the correct answer is option D.
