How unit 2 is examined
This unit covers the resources of an information system (OAS, TPS), information resource management, IT infrastructure, business integration and models, and data processing; the last two topics carry the marks.
Resources and Components of Information Systems
<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Low weight</span>
Definition. <mark>An information system is an organised combination of hardware, software, data, people and procedures that collects, processes, stores and distributes information to support operations and decisions.</mark>
Key points.
- The five resources are hardware (computers, devices), software (programs), data (raw facts), people (users and specialists) and procedures (rules for using the system).
- An Office Automation System (OAS) uses computers and networks for office work such as word processing, email, scheduling, spreadsheets and video conferencing, e.g. MS Office or Google Workspace.
- A Transaction Processing System (TPS) records and processes routine day-to-day business transactions such as sales, billing, payroll and reservations, e.g. an ATM or railway ticket booking.
- TPS features are high volume, repetitive, structured data, fast response, accuracy and a reliable audit trail; OAS features are document handling, communication and coordination among office staff.
- OAS is needed in MIS because it speeds up communication, reduces paperwork, lets people share documents and calendars, and supplies well-organised information that MIS reports and managers depend on.
| Basis | OAS | TPS |
|---|---|---|
| Purpose | Support office communication and documents | Record routine business transactions |
| Data handled | Documents, messages, schedules | Sales, payments, orders |
| Structure | Mostly unstructured | Highly structured, repetitive |
| Users | Clerks, managers, office staff | Operational-level staff |
| Output | Letters, mails, reports | Updated records, receipts, feed for MIS |
| Example | Email, MS Word | Billing, payroll, ATM |
Pitfall: Do not define OAS as only typing; include communication and coordination, and always give the "need in MIS" points, since the question asks for them.
Asked: [7 marks] (Nov 2022) Explain Office Automation Systems (OAS) and Transaction Processing Systems. What is the need for OAS in the management information system?
Managing Information Resources in an Organization
<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Low weight</span>
Definition. <mark>Information resource management is the planning, organising, securing and controlling of data, systems and people so that information stays available, accurate and protected.</mark>
Key points.
- Organise data in a central database with standard naming, classification and indexing, so that it can be stored once and retrieved quickly by any authorised user.
- Control access through passwords, user roles and authentication, so that each person sees only the data the job needs (least privilege).
- Keep regular backups, stored off-site, together with a disaster recovery plan so that data survives hardware failure, attack or accident.
- Protect data with encryption, firewalls, antivirus and audit logs, and define written security and usage policies that staff are trained to follow.
- Assign ownership, so that named data owners keep information current, and retire obsolete data on a schedule.
- Balance accessibility with confidentiality and integrity: information must be easy to reach for the right people, yet closed to others and safe from unauthorised change.
Asked: [7 marks] (Nov 2023) Discuss the strategies for effectively managing information resources in an organization, considering security and accessibility.
IT infrastructure and upcoming technologies
<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Low weight</span>
Definition. <mark>IT infrastructure is the combined hardware, software, network, data and people that together provide the base on which an organization's information systems run.</mark>
Key points.
- Hardware and software must suit the expected workload and be compatible with existing systems, so that new parts work with old ones.
- The network must give enough bandwidth, speed and reliability to connect users, branches and servers.
- Data storage, database and backup needs must be planned for the volume and type of data.
- Scalability lets the infrastructure grow with users and data without a complete redesign.
- Security must protect systems and data, while cost, covering purchase, running and maintenance, has to stay within budget.
- Skilled people must operate the infrastructure, and the whole design must align with business goals.
- Upcoming technologies such as cloud computing, artificial intelligence, IoT and mobile computing should be considered so that the design does not become obsolete.
Asked: [7 marks] (Nov 2022) Explain the factors to be considered in designing IT infrastructure.
Integration and automation of Business Functions and developing Business Models
<span style="display:inline-block;padding:.16em .6em;border:1.5px solid currentColor;border-radius:999px;font-size:.68em;font-weight:700;letter-spacing:.06em;text-transform:uppercase;opacity:.75">Medium weight</span>
Definition. <mark>A business model describes how an organization creates value for its customers, delivers it and earns revenue from it.</mark>
Key points.
- Integration links business functions such as sales, finance, production, inventory and HR on shared data, removing information silos and duplicate data entry.
- Automation makes software perform repetitive tasks, which brings speed, accuracy and lower cost.
- Together they give managers timely, consistent and complete information, so decisions become faster and better and the whole organization runs more efficiently.
- The value proposition is the benefit the customer receives; the revenue model is how the firm earns money from it.
- B2B (business to business) sells to other firms, e.g. Alibaba or a raw-material supplier.
- B2C (business to consumer) sells directly to consumers, e.g. Amazon or Flipkart.
- The subscription model charges a recurring fee for continued access, e.g. Netflix; other common types are C2C marketplaces (OLX) and freemium (free basic plan, paid upgrade).
| Model | Who sells to whom | Example |
|---|---|---|
| B2B | Business to business | Alibaba |
| B2C | Business to consumer | Amazon |
| C2C | Consumer to consumer | OLX |
| Subscription | Recurring fee for access | Netflix |
Answer frame. For the business model question: open with the definition; explain value proposition and revenue model; develop points 5-7 with one example each; close by saying the model must fit the market. For the integration question: define integration and automation; develop points 1-3 with efficiency and decision benefits; close with the example of one shared database serving all departments.
Asked: [7 marks] (Nov 2022) What is business model? Explain some common types of business models. Asked: [7 marks] (Nov 2023) How does the integration and automation of business functions enhance efficiency and decision-making in an organization?

Steps.
Step 1: Collection - gather raw data from its sources.
Step 2: Input - enter and validate the data in the system.
Step 3: Processing - sort, calculate, classify and summarise it.
Step 4: Output - present results as reports, screens or charts.
Step 5: Storage - save data and results for later use.
Key points.
- Collection must be accurate and complete, because wrong input gives wrong output.
- Processing operations include sorting, merging, calculating, classifying and summarising.
- Batch processing collects data and processes it in groups at set times, e.g. monthly payroll.
- Online or real-time processing handles each transaction as it occurs, e.g. bank ATM or seat booking.
- Distributed processing spreads the work over several connected computers.
- For MIS, data processing supplies timely and accurate information, which supports better decisions.
Answer frame. Open with the definition; draw the cycle of five boxes; develop the steps, then the modes with examples; close with its role in decision-making.
Asked: [7 marks] (Nov 2022, Nov 2023) Explain fundamentals of data processing. Elaborate on the fundamentals of data processing and their role in supporting organizational decision-making.
