Question One Question Two Question Three Consider you are tasked with implementing a new payroll system that will allow employees to record time card information electronically and generate pay checks based on the number of hours worked and total amount of sales. It possess a Windows -based desktop interface to allow employees to enter timecard information, change employee preferences (such as payment method), enter purchase order s, and create various reports. Every employee can access and edit their own time cards and purchase orders from any browser running on organization's intranet. Which architecture would best suit to impl ement the above system and why? Highlight the advantages of the suggested architecture when compare d to other architecture designs Answers: An online shop about to give free vouchers to its customers with the following specifications:  A customer will deserve a 10 S.R. voucher for each 100 S.R. of their spent once the order reaches 500 S.R. or more.  These vouchers have ID and valid for one full year  Only one voucher can be used at the time.

You are asked to help this shop in writing two pseudocodes : one for giving vouchers and one for using a voucher. Answer: You have been introduced to different data storage format such as legacy, relational, object, and multidimensional. Using your own words, based on what data storage format is chosen. Support your answer with examples of what each type /format can provide or support. Answer:

Paper For Above instruction

The management of enterprise systems requires careful architecture selection to ensure efficiency, security, and scalability. When designing systems like a payroll platform accessible via both desktop and web interfaces, a multi-tier or hybrid architecture is often ideal. For the given payroll system, a client-server architecture, specifically a web-based client-server model combined with a desktop client interface, would be most suitable. This architecture separates the user interface from the data processing logic and data storage, providing flexibility, scalability, and ease of maintenance.

In this setup, the employees interact with a Windows-based desktop application to input timecard information and preferences, which communicates with a backend server through secure APIs. The web interface allows employees to access and edit their data from any browser on the intranet. The backend server manages the core processing, data security, and storage, typically through a relational database that ensures data integrity and efficient query handling.

Advantages of this architecture include scalability—additional servers or modules can be added as the organization grows; flexibility—users can operate via desktop or browsers; and security—centralized data control reduces risks of data breaches. Compared to monolithic systems, this architecture promotes modular updates and easier debugging. Unlike peer-to-peer models, client-server centralizes data, increasing security and simplifying backup processes.

Regarding the online shop policy for customer vouchers, pseudocode can be structured as follows:

Voucher Allocation Pseudocode



function issueVoucher(orderAmount, customerID):


if orderAmount >= 500:


vouchersCount = floor(orderAmount / 100)


for i from 1 to vouchersCount:


voucherID = generateUniqueVoucherID()


expiryDate = getDatePlusOneYear()


saveVoucher(voucherID, customerID, expiryDate, status='unused')


return "Vouchers issued successfully."


else:


return "Order amount less than threshold; no vouchers issued."

Voucher Usage Pseudocode



function useVoucher(voucherID, orderAmount):


voucher = retrieveVoucher(voucherID)


if voucher exists and voucher.status == 'unused' and currentDate 

if orderAmount >= 500:


discount = (floor(orderAmount / 100)) * 10


voucher.status = 'used'


updateVoucher(voucher)


applyDiscount(discount)


return "Voucher applied successfully."


else:


return "Order amount does not qualify for vouchers."


else:


return "Invalid or expired voucher."

Lastly, the choice of data storage formats impacts system design significantly. Legacy storage systems are outdated, often with poor compatibility and scalability. Relational databases organize data into tables with clearly defined relationships—examples include MySQL and PostgreSQL—making data retrieval efficient for structured data and supporting complex queries. Object-oriented storage encapsulates data and behaviors into objects, suitable for applications requiring complex data models like CAD systems. Multidimensional databases are optimized for analytical processing, often used in data warehousing to support business intelligence operations.

For enterprise payroll systems with transactional data, relational databases are typically preferred due to their robustness, data integrity constraints, and support for ACID properties. They facilitate efficient transaction management, which is crucial for payroll processing where accuracy and consistency are mandatory. Object databases are more suited when system design involves complex data models that mirror real-world objects. Multidimensional databases support analytical queries, which are less common in payroll systems but valuable for reporting and data analysis tasks.
