Introduction To Software Engineering & Point-Of-Sales (POS) System - Engineering Assignment Help

Assignment Task

Requirements Engineering
The question relates to the administrative part of an online (i.e. web based) drop-shipping, Point-Of-Sales (POS) system tool that might be suitable for regulating secured purchases at checkout carts such as those on shopify, oberlo, etc. The question provides a narrative, which you must turn into structured specifications.
Narrative:
The drop shipping seller must set up a drop shipping website inventory before online customers can begin buying using the shopping facility. He or she needs to create a point of sales system which allows customers to pick the products they like from the site and put them into a checkout basket. The seller can also apply certain discounts that may come around seasonally, which their vendor / suppliers can give - to market the product more
competitively. During purchase, the checkout should apply price adjustments in import / export duties, delivery and taxes. It should also securely authenticate the buyer’s credentials and debit his account. A receipt should be given to the buyer at the end of the transaction. The seller then passes on a sale order to the vendor / supplier who then ships the it to the customer. (Ignore refunds, returns or customer service) Human roles, computing systems, or concepts referred to in the narrative are not explained. For example, the software developers who are one of the target audiences of these specification may not have studied sales and accounting before and may not understand terms like “delivery”, “tax”, “checkout”, “debit”, “receipt”, etc. You must provide a glossary that explains any such terms used in your specifications which might not be clear. Again, you may have to be creative when something is unclear, but the terms mentioned above should already be known to you. In your definition, as well as explaining the concept, you should list what properties or attributes define or uniquely identify such an
entity as well as other important attributes. This will help you to know how the system will work and what needs to be entered. For example, given a basket of checkout items, what else is needed to define a checkout submission.
