3 Distinguish between data warehouse and a data mart?
A database is a system for storing transactional data (OLTP). A data mart is a repository for analytical data (OLAP). A database is a collection of information about a single topic's various features and activities. Data from many subjects will be stored in a data mart.

Why it is necessary to demultiplex AD0 to AD7 address lines?
Demultiplexing the AD0 to AD7 address lines is necessary to separate the address and data signals in microprocessor systems, particularly in those where a single set of lines is used for both functions. This allows for more efficient use of the bus, as the same lines can carry address information during one phase of operation and data during another. By demultiplexing, the system can clearly distinguish between when it needs to read or write data versus when it is accessing specific memory addresses, ensuring accurate communication and reducing the risk of errors. Additionally, it helps in simplifying the design of the bus architecture and enhances overall system performance.
How the processor uses the address bus the data bus and the control bus to communicate with the memory (System Memory)?
The processor uses the address bus to specify the memory location it wants to read from or write to by sending the corresponding address signals. Once the address is set, the data bus is used to transfer the actual data between the processor and the memory; it carries data to be written or read data from the specified address. The control bus carries control signals that manage the operations, such as read or write commands, ensuring that the correct actions are performed during communication. Together, these buses facilitate efficient data transfer and coordination between the processor and system memory.
Defne an information system from both a technical and a business perspective and distinguish between computer literacy and informatiom systems literacy?
From the technical perspective, an Information System is a system capable of accepting, storing, safeguarding, retrieving, analyzing, and delivering data. Generally, this is accomplished over a network (either local ore remote) of computers, servers, and peripherals. From the business perspective, an Information System is a system capable of doing the above, but also is able to take the raw data and turn it into something useful/meaningful.
What are the main components of the system bus?
The main components of the system bus include the data bus, address bus, and control bus. The data bus carries the actual data being transferred between components, the address bus specifies the memory locations or device addresses involved in the transaction, and the control bus transmits control signals to coordinate and manage the operations of the system. Together, these buses facilitate communication between the CPU, memory, and peripheral devices.
What is the Importance of latch in ALE?
The latch in Address Latch Enable (ALE) is crucial for separating the address and data phases in microprocessor operations. When ALE is activated, it allows the address bus to capture the address from the processor while preventing data from being mistakenly read or written. This ensures accurate data transfer and prevents conflicts on the bus, enhancing the overall reliability of the system. In essence, the latch helps maintain data integrity during the transition between address and data signals.
Distinguish between primary data and secondary data?
The difference is rimary data is information personally or originally collected that has not been studied. Secondary data is information already collected, examined and concluded.
What are the merits of tabular representation of data?
They are:1] it is useful to distinguish between raw data tables and analytic tables2] It is a way of conveying information to a reader or to readers
What is the difference between data redundancy and data inconsistency?
Redundancy is data that is not needed or no longer needed. Inconsistency is where you have different data for what should be the same thing, as a result of one piece of data having a few copies and not all of them being updated. So if someone's address is on a system several times, and then their address changes, but it is only updated in some of those places, then the person will have both their old and new address on the system. The data is not consistent then. To avoid this data should be only stored once and everyone that needs it looks at the one set, rather than each having their own copy.
