database . - The information is collected in order to establish details about the entities, relationships among the entities generated.
- Business rules that are shaped up through relationships, connectivity and cardinalities are being obtained and collected through designer.
Question that can be asked in order to create an information system:
The below are some of the sample questions that can impact the design of the database:
- Is it required to develop the database for all departments at once or whether it is required to design and implement the database for one particular department?
- What will the design approach required that could affect the process of designing?
- What type of development is required, one module at a time or integrated system approaches (Example: Billing, production, shipping and inventory)?
- What type of tracking system is required that is in terms of tracking the nuts and bolts through lot number, by shift, by production, by type or by department?
- What type of tracking system is required for the suppliers of each batch that is in terms raw materials used in the production of the nuts and bolts?
- Is it required to track the customer information regarding the receive summary of nuts and bolts based on batches?
- What type of reporting system is required that is what type of reporting requirements are required and who requires the distribution report details needs to be specified?
Effect of the questions that are asked:
The answers to the above question affect the database design in conceptual and in logical way along with the implementation, testing made with the subsequent operations.

Identify the patterns in the given data. And determine how are the data points are related. Refer to the raw data (table):arrow_forward3A) Generate a hash table for the following values: 11, 9, 6, 28, 19, 46, 34, 14. Assume the table size is 9 and the primary hash function is h(k) = k % 9. i) Hash table using quadratic probing ii) Hash table with a secondary hash function of h2(k) = 7- (k%7) 3B) Demonstrate with a suitable example, any three possible ways to remove the keys and yet maintaining the properties of a B-Tree. 3C) Differentiate between Greedy and Dynamic Programming.arrow_forward
- What are the charts (with their title name) that could be use to illustrate the data? Please give picture examples.arrow_forwardA design for a synchronous divide-by-six Gray counter isrequired which meets the following specification.The system has 2 inputs, PAUSE and SKIP:• While PAUSE and SKIP are not asserted (logic 0), thecounter continually loops through the Gray coded binarysequence {0002, 0012, 0112, 0102, 1102, 1112}.• If PAUSE is asserted (logic 1) when the counter is onnumber 0102, it stays here until it becomes unasserted (atwhich point it continues counting as before).• While SKIP is asserted (logic 1), the counter misses outodd numbers, i.e. it loops through the sequence {0002,0112, 1102}.The system has 4 outputs, BIT3, BIT2, BIT1, and WAITING:• BIT3, BIT2, and BIT1 are unconditional outputsrepresenting the current number, where BIT3 is the mostsignificant-bit and BIT1 is the least-significant-bit.• An active-high conditional output WAITING should beasserted (logic 1) whenever the counter is paused at 0102.(a) Draw an ASM chart for a synchronous system to providethe functionality described above.(b)…arrow_forwardS A B D FL I C J E G H T K L Figure 1: Search tree 1. Uninformed search algorithms (6 points) Based on the search tree in Figure 1, provide the trace to find a path from the start node S to a goal node T for the following three uninformed search algorithms. When a node has multiple successors, use the left-to-right convention. a. Depth first search (2 points) b. Breadth first search (2 points) c. Iterative deepening search (2 points)arrow_forward
- We want to get an idea of how many tickets we have and what our issues are. Print the ticket ID number, ticket description, ticket priority, ticket status, and, if the information is available, employee first name assigned to it for our records. Include all tickets regardless of whether they have been assigned to an employee or not. Sort it alphabetically by ticket status, and then numerically by ticket ID, with the lower ticket IDs on top.arrow_forwardFigure 1 shows an ASM chart representing the operation of a controller. Stateassignments for each state are indicated in square brackets for [Q1, Q0].Using the ASM design technique:(a) Produce a State Transition Table from the ASM Chart in Figure 1.(b) Extract minimised Boolean expressions from your state transition tablefor Q1, Q0, DISPATCH and REJECT. Show all your working.(c) Implement your design using AND/OR/NOT logic gates and risingedgetriggered D-type Flip Flops. Your answer should include a circuitschematic.arrow_forwardA controller is required for a home security alarm, providing the followingfunctionality. The alarm does nothing while it is disarmed (‘switched off’). It canbe armed (‘switched on’) by entering a PIN on the keypad. Whenever thealarm is armed, it can be disarmed by entering the PIN on the keypad.If motion is detected while the alarm is armed, the siren should sound AND asingle SMS message sent to the police to notify them. Further motion shouldnot result in more messages being sent. If the siren is sounding, it can only bedisarmed by entering the PIN on the keypad. Once the alarm is disarmed, asingle SMS should be sent to the police to notify them.Two (active-high) input signals are provided to the controller:MOTION: Asserted while motion is detected inside the home.PIN: Asserted for a single clock cycle whenever the PIN has beencorrectly entered on the keypad.The controller must provide two (active-high) outputs:SIREN: The siren sounds while this output is asserted.POLICE: One SMS…arrow_forward
