Distributed databases provide several advantages over centralized databases, including improved scalability, availability, performance, flexibility, fault tolerance, and security1. Here are some of the advantages of distributed databases:

Increased availability: Distributed databases can tolerate failures of individual nodes or sites without affecting the overall system functionality. Users can access data from other sites if their local site is down or unreachable.Data replication and backup mechanisms can also enhance data availability and recovery2.

Easier expansion: Distributed databases can be scaled horizontally by adding more nodes to the network. This allows for increased capacity and performance as data and user demand grow.Adding new sites or units to the distributed system does not require significant efforts or disruption in the existing functions2.

Improved performance: Distributed databases can offer faster response and lower communication costs by locating data near the users who normally use that data. Distributed query processing and transaction management can also optimize the use of network and computing resources.Furthermore, distributed databases can exploit the parallelism of multiple nodes to execute operations concurrently13.

Object-oriented analysis (OOA) is the first technical activity performed as part of object-oriented software engineering. OOA involves modeling the problem domain using objects and their interactions.According to the CITM study guide, there are five steps involved to undertake an object-oriented analysis1:

Find and define the objects

Organize the objects

Describe how the objects interact with one another

Define the external behavior of the objects

Define the internal behavior of the objectsReference:1: CITM Study Guide, Chapter 4: Object-Oriented Analysis and Design, Page 63-64.

Systems analysis is the second step in the Systems Design Life Cycle (SDLC), which is a process for planning, creating, testing, and deploying an information system. Systems analysis involves gathering and analyzing the requirements of the system, such as the user needs, the business objectives, and the functional specifications. Systems analysis also involves modeling the system using various techniques, such as data flow diagrams, entity-relationship diagrams, and use case diagrams. Systems analysis helps to define the scope and boundaries of the system, as well as the inputs, outputs, processes, and data structures.Systems analysis is essential for ensuring that the system design meets the expectations and needs of the stakeholders.Reference:1,2,3,4

Globalization is the process of increasing economic, political, and cultural integration and interdependence across the world. Some of the impacts of globalization are:

Rationalized manufacturing: Globalization enables firms to produce goods and services in different locations according to their comparative advantages, such as lower costs, higher quality, or better access to markets. This leads to more efficient and competitive production, as well as increased specialization and trade.

Managing risk across currencies: Globalization exposes firms and individuals to fluctuations in exchange rates, which affect the value of their assets, liabilities, and incomes. To manage this risk, they may use various financial instruments, such as hedging, derivatives, or currency swaps, to reduce their exposure or benefit from favorable movements.

Worldwide purchase: Globalization expands the range and availability of goods and services that consumers can purchase from different countries and regions. This increases consumer choice, lowers prices, and improves quality and variety. It also creates opportunities for cross-cultural learning and exchange.

The second step in System Analysis is to conduct a feasibility study, which is an assessment of the technical, economic, legal, operational, and schedule aspects of the proposed system. A feasibility study helps to determine whether the system is viable, beneficial, and achievable within the given constraints and resources.A feasibility study also helps to identify the risks, costs, benefits, and alternatives of the system.Reference:1,2,3

Data are often proprietary or confidential because they contain valuable information that can give a competitive advantage to the owner or affect the privacy of the individuals or entities involved. Data can be classified into different levels of sensitivity and protection, depending on the potential impact of unauthorized disclosure, modification, or loss. For example, data that contain personal, financial, or health information of customers or employees are usually considered highly confidential and require strict security measures. Data that contain trade secrets, intellectual property, or strategic plans are also typically proprietary and confidential, as they can affect the market position or reputation of the owner. Data that are public or non-sensitive, such as general information about products or services, may not require the same level of protection, but still need to be managed and maintained properly.Reference:CITM Course Outline, Module 6 - Data Management, Section 6.1 - Data Classification and Protection;Sample Exam, Question 72.

According to the CITM study guide, an international firm can adopt different business models depending on its degree of global integration and local responsiveness. The study guide identifies four types of business models: international, multidomestic, global, and transnational. These are similar to the typology of multinational companies proposed by Bartlett and Ghoshal (1989). The study guide defines each business model as follows:

International: The firm operates in multiple countries but has a low degree of global integration and local responsiveness. The firm's subsidiaries are largely independent and follow the parent company's strategy and culture. The firm exploits its core competencies and capabilities across different markets without much adaptation. This business model is also known as theinternational projectoror thecentralized exporter.

Multidomestic: The firm operates in multiple countries and has a high degree of local responsiveness but a low degree of global integration. The firm's subsidiaries are highly autonomous and tailor their products and services to the specific needs and preferences of the local markets. The firm sacrifices efficiency and standardization for differentiation and customization. This business model is also known as themultinational drivenor thedecentralized federation.

Global: The firm operates in multiple countries and has a high degree of global integration but a low degree of local responsiveness. The firm's subsidiaries are highly dependent on the parent company and follow a standardized and centralized strategy and culture. The firm leverages economies of scale and scope to achieve cost efficiency and competitiveness. This business model is also known as theintegrated global ITor thecoordinated federation.

Transnational: The firm operates in multiple countries and has a high degree of both global integration and local responsiveness. The firm's subsidiaries are interdependent and collaborate with each other and the parent company to share and transfer knowledge, resources, and best practices. The firm balances efficiency and adaptation to achieve innovation and learning. This business model is also known as theintellectual synergyor theheterarchical network.

Based on these definitions, the three business models that an international firm might adhere to are B, C, and D. Option A is not a valid business model, but rather a characteristic of the transnational business model.Reference:

Reciprocal interdependence occurs when two organizations depend on each other in a cyclical manner, such that the output of one becomes the input of the other and vice versa. This type of interdependence is the most complex and difficult to manage, as it requires constant coordination and communication between the organizations. An example of reciprocal interdependence is the relationship between a software development company and a software testing company, where each one relies on the feedback and quality of the other's work.Reference:Three Types of Interdependence in an Organizational Structure,Interdependence in International Organization and Global Governance

Sequential interdependence occurs when the output of one unit or group becomes the input for another. This type of interdependence requires coordination and communication among the units or groups involved, as any delay or error in one unit can affect the performance of the next unit.An example of sequential interdependence is an assembly line, where each stage of production depends on the previous one12Reference:

Step three (3) in undertaking of object-oriented analysis does not define the methods, but rather identifies the states of each object and the events that affect them. Methods are defined in step four (4), which is the object-oriented design phase. Methods are the operations or functions that an object can perform to achieve its objectives or respond to events.Reference:Object-Oriented Analysis and Design | OOAD - GeeksforGeeks,Steps to Analyze and Design Object Oriented System - GeeksforGeeks,OOAD - Object Oriented Analysis - Online Tutorials Library
