According to the Certified IT Manager (CITM) course outline, there are nine stages in a systems design life-cycle. They are: 1. Initiation, 2. Concept Development, 3. Planning, 4. Requirements Analysis, 5. Design, 6. Development, 7. Integration and Test, 8. Implementation, and 9.Operations and Maintenance. Each stage has its own objectives, deliverables, and activities that ensure a systematic and effective approach to system development. References: CITM Course Outline, System Development Life Cycle - GeeksforGeeks, Systems development life cycle - Wikipedia

 Classes are a representation of some real-world thing and a number of specific instances of that thing. Classes define the common characteristics and behaviors of a group of objects, such as properties, methods, and events. Objects are individual instances of classes that can have different values for the properties and variables defined by the class. Procedures are blocks of code that perform a specific task or function. Links are connections between objects that allow communication and interaction. References: Objects and Classes – Programming Fundamentals, Objects and classes - Visual Basic, Object-Oriented Programming: Objects, Classes & Methods

 In a database, each row represents a single, implicitly structured data item in a table. A row is also called a record or a tuple. A record contains multiple fields, each one defined in a different column. A field is the intersection of a row and a column, and it holds a single value. A column is also called an attribute or a field name, and it defines the type and constraints of the data in that column. References:

 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 the international projector or the centralized 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 the multinational driven or the decentralized 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 the integrated global IT or the coordinated 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 the intellectual synergy or the heterarchical 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. References:

Development cost is the type of cost that is considered as actual costs of analysis, design, and installation for the system. Development cost includes the expenses incurred during the planning, designing, building, testing, and deploying of a system. Development cost is usually estimated before the start of a project and is used to measure the feasibility and profitability of a system. Development cost is also used to monitor the progress and performance of a project and to control the scope and quality of a system. References: CITM Course Outline, Module 4, Corporate IT Strategy, page 9. CITM Training Course, Cost, page 14. CITM Certification Overview, Exam Information, Course Outline, Module 4.

Restrictions on Internet access and efforts to censor web sites may impede the development of a global information system by limiting the availability, diversity, and quality of information that can be accessed and shared across borders. Such restrictions may also hamper the innovation, collaboration, and communication that are essential for the advancement of technology, science, and society. According to the CITM study guide, a global information system is “a system that collects, processes, stores, and disseminates information that is relevant to the needs of users in different countries” (p. 26). The benefits of a global information system include “improved decision making, enhanced coordination, increased efficiency, reduced costs, and greater customer satisfaction” (p. 26). However, these benefits can be undermined by various forms of internet censorship, such as:

Manipulating search results to favor certain sources or viewpoints, or to hide or distort information that is unfavorable to the censoring authority.

Blocking access to specific sites or domains that contain information that is deemed illegal, immoral, or politically sensitive by the censoring authority.

Shutting off internet access altogether or imposing bandwidth limitations during times of crisis, protest, or conflict to prevent the dissemination of information that could challenge the status quo or mobilize opposition.

Requiring users to register or obtain licenses to access certain sites or services, or to use encryption or VPNs, which can deter or restrict internet usage and expose users to surveillance or prosecution.

Monitoring, filtering, or deleting online content or communications that are considered harmful, offensive, or subversive by the censoring authority, or imposing self-censorship through legal or social pressure.

These forms of internet censorship can have negative impacts on the development of a global information system, such as:

Reducing the amount and variety of information that is available to users in different countries, which can limit their knowledge, awareness, and understanding of global issues and perspectives.

Lowering the quality and reliability of information that is available to users in different countries, which can impair their ability to make informed and rational decisions, or to verify and challenge the information they receive.

Restricting the opportunities and platforms for users in different countries to exchange and share information, ideas, opinions, and feedback, which can hinder their collaboration, innovation, and creativity.

Violating the rights and freedoms of users in different countries to access and express information, which can undermine their participation, representation, and empowerment in the global society.

A primary key is a column or combination of columns that contain values that uniquely identify each row in the table. It enforces the entity integrity of the table and prevents the insertion of duplicate rows. A table can have only one primary key, which is usually defined on an identity column or a column with not null and unique constraints. A primary key also creates a unique index for the table, which allows fast access to data when the primary key is used in queries12. References: 1: Primary and Foreign Key Constraints - SQL Server12: Primary and Foreign Key in SQL With Examples - DataFlair2

An ER diagram (Entity-Relationship diagram) is a type of diagram that consists of object types and relationships. An object type is a category of objects that share common attributes and behaviors, such as a class, an entity, or a component. A relationship is a connection or association between two or more object types, such as an inheritance, an aggregation, or a dependency. An ER diagram is used to model the structure and semantics of a system, such as a database, a software system, or a business domain. An ER diagram can show the cardinality, optionality, and constraints of the relationships, as well as the attributes and operations of the object types. References: What is an Entity Relationship Diagram (ERD)?, Object Diagrams | Unified Modeling Language (UML), The Easy Guide to UML Class Diagrams | Class Diagram Tutorial, Class diagrams vs Object diagrams in UML

Tangible costs are those that can be easily quantified and measured, such as direct expenses or physical assets. However, in some cases, tangible costs savings can be difficult to estimatebecause they depend on various factors, such as the expected life cycle of the asset, the depreciation rate, the maintenance costs, the opportunity costs, and the market conditions. For example, if a company invests in a new production machine, the tangible cost savings would be the difference between the cost of the old machine and the cost of the new machine, plus the additional benefits of the new machine, such as higher output, lower energy consumption, and improved quality. However, these benefits may not be easy to measure or predict, especially in the long term. Therefore, tangible costs savings can be difficult to estimate in some cases. References: Tangible Cost: Meaning and Difference From Intangible Costs - Investopedia, What Are Tangible Costs?

A worm is a type of malicious code that can distribute itself without using having to attach to a host file. Unlike a virus, which needs to infect an existing program or file to spread, a worm can create copies of itself and send them to other devices through a network. A worm can consume network bandwidth, slow down the system performance, or deliver a payload that can damage or compromise the security of the infected device. According to the CITM study guide, a worm is “a self-replicating program that does not alter files but resides in active memory and duplicates itself” (p. 70). Some examples of worms are Stuxnet, Conficker, and Blaster. References:
