1. We have structure pane and class n object pane in UDT, in IDT, they have Data foundation layer (in stead of structure pane) and Business Layer (instead of Class n object pane). First of all, a project is created, then a relational or OLAP connection, then data foundation and then business layer. Then the universe is published as .unx 2. In IDT, the biggest advantage is that you have create universe based on multiple data sources. It could be different relational data sources (must be 64-bit)

* How the Internet works * Packet-switching technology Actual data transmission takes place sporadically, rather than continuously. Data to be transmitted is divided into small packets of information and labeled to identify the sender and recipient. These are sent over a network and then reassembled at their destination. If any packet did not arrive or was not intact, original sender requested to resend the packet. -> This enables millions to transmit data at the same time. * Understand

cursor is a variable that runs through the tuples of some relation. This relation can be a stored table, or it can be the answer to some query. By fetching into the cursor each tuple of the relation, we can write a program to read and process the value of each such tuple. If the relation is stored, we can also update or delete the tuple at the current cursor position. The example below illustrates a cursor loop. It uses our example relation T1(e,f) whose tuples are pairs of integers. The program will
