| 1 | SUN | 352-765 |
| 2 | Anime | 654-123 |
Officer details:
| Officer_id | OfficerName | OfficerTitle |
| 1 | Ram Kumar | ceo |
| 2 | Rajesh | Project Head |
Sales details:
| Industry_id | Officer_id | Gross Sales |
| 1 | 1 | 23000000 |
| 2 | 2 | 45000000 |
| 1 | 2 | 50000000 |
- Number of themes: Three
- Name of the theme: Industry details, officer details, and Sales
Assumptions:
In the above spreadsheet, there are three themes. One of the themes is about industry which is specified through the heading of Name and IndustryCode. The other theme is about officer who is specified through the heading of OfficerName and OfficerTitle. The final theme is about sales which are specified through the heading of Gross Sales.
- Industry – It contains Industry_id, Name and IndustryCode attributes. The Industry_id is the primary key of the Industry table.
- Officer – It contains Officer_id, OfficerName, and OfficerTitle attributes. The Officer_id is the primary key of the Officer table.
- Sales – It contains Industry_id, Officer_id, and Gross Sales attributes.

This ALU will implement a bitwise left rotation. Forthis lab assignment you are not allowed to use Digital's Arithmetic components.IF YOU ARE FOUND USING THEM, YOU WILL RECEIVE A ZERO FOR LAB2!The ALU you will be implementing consists of two 4-bit inputs (named inA and inB) and one 4-bit output (named out). Your ALU must rotate the bits in inA by the amount given by inB (i.e. 0-15).Part-1: User InterfaceYou are provided an interface file lab2_part1.dig; start Part-1 from this file.NOTE: You are not permitted to edit the content inside the dotted lines rectangle. Part-1: ExampleIn the figure above, the input values that we have selected to test are inA = {inA_3, inA_2, inA_1, inA_0} = {0, 1, 0,0} and inB = {inB_3, inB_2, inB_1, inB_0} = {0, 0, 1, 0}. Therefore, we must rotate the bus 0100 bitwise left by00102, or 2 in base 10, to get {0, 0, 0, 1}. Please note that a rotation left is…arrow_forward
