- Draw a Use Case Diagram where a customer will buy a Product online using credit card. Customer browses the online products catalog & selects the items to buy. Then he can do the check out. Also, customer can fill in shipping information (address, next-day or 3-day delivery). The online system shows the product details with full pricing information. When the customer selects the products then he can fill in credit card information. Then online system will authorize the purchase and confirms the sale immediately and at the same time system sends the confirmation email to the customer.Create a Process Flow diagram/chart based on the following: Customer Places Order: The customer places an order through the trading platform, specifying the instrument, quantity, and order type (market order, limit order, stop-loss order, etc.). Order Routing: The trading platform receives the order and routes it to the appropriate market or exchange. Order Matching: The order is placed in the order book, where it is matched with other orders based on price and time priority. Trade Execution: If a match is found, a trade is executed. The trade details, including price, quantity, and counterparty, are recorded. Trade Confirmation: The trade is confirmed to both parties involved, and the corresponding accounts are updated. Settlement: The trade is settled, and the securities or funds are transferred accordingly. Roles and Decisions: Customer: Decides on the order type, quantity, and instrument to trade. Trading Platform: Routes orders to the appropriate market, matches orders, executes…Business process modeling is a graphical representation of a company’s business processes or workflows. As a means of identifying potential improvement in a business process, you are required to identify an ‘AS IS’ (existing) business process in your firm and model the process.You are to note the following conditions for the task:1. The identified process must be Cross-functional which should include not less than four (4) decision points (Gateways).2. Make sure you list all the steps in the identified process before modeling.3. Describe how information systems could be used to improve the “AS IS” process4. Remodel the ‘AS IS’ process to “TO BE” (modified) process after identifying improvement with the Information systems.
- Develop an activity diagram based on the following narrative. Note any ambiguities or questions that you have as you develop the model. If you need to make assumptions, also note them. The purpose of the Open Access Insurance System is to provide automotive insurance to car owners. Initially, prospective customers fill out an insurance application, which provides information about the customer and his or her vehicles. This information is sent to an agent, who sends it to various insurance companies to get quotes for insurance. When the responses return, the agent then determines the best policy for the type and level of coverage desired and gives the customer a copy of the insurance policy proposal and quote.Computer Science Scenario: You are a Systems Auditor for Windhoek University, an institution that offers higher education to those who wish to further their studies after high school. The institution consists of a number of faculties such as Accounting, Hospitality and Agriculture to mention a few. Just like any compliant institution, Windhoek University is required to have annual IT audits of their infrastructure and operations.

In preparation for this, you have been tasked to conduct an Audit Planning Process. In the process, you realise that the labs are freely accessible to anyone and the computers require no log in credentials to use them. Meanwhile, you discover that the university’s web server has been defaced and the students’ account are active and have administration rights on the systems. There has been a major configuration change to the web…DRAW A DETAILED LEVEL 0 DIAGRAM FOR THE FOLLOWING ACTIVITIES. THEN DRAW CONTEXT LEVEL DATA FLOW DIAGRAM.

When the order is shipped to the customer address, the customer is billed( Produce bill). The system also produces inventory reports to accounting department.
