System Integration, Enterprise Architecture, and IT Governance Flashcards

Flashcards covering key concepts of System Integration, Enterprise Architecture, Enterprise Information Architecture, IT Governance, and Information/Data Modeling.

What is System Integration?

The process of combining various subsystems or components to work together as a unified system to ensure seamless communication and data exchange.

What is Horizontal Integration?

An integration type that connects different systems or applications at the same level of the technology stack.

What is Vertical Integration?

An integration type that connects systems across different levels of the technology stack, such as linking data sources with applications and user interfaces.

What is Functional Integration?

An integration type that focuses on integrating different functionalities or modules within the same system.

What is Middleware?

Software that facilitates communication between different systems or applications, acting as an intermediary to share data effectively.

What is the primary function of Message Brokers?

To facilitate message exchange between different systems.

What is the primary function of API Gateways?

To manage and route API requests, ensuring proper communication between clients and services.

What is the primary function of Database Middleware?

To connect applications to databases, handling data transactions and queries.

What are Application Programming Interfaces (APIs)?

Sets of rules and protocols that allow different software applications to communicate with each other by defining request and response formats.

What is Monolithic Architecture?

An architectural style where all components of the application are interconnected and operate as a single unit.

What is Layered Architecture?

An architectural style that divides the system into distinct layers (e.g., presentation, business logic, data access) that interact in a hierarchical manner.

What is Microservices Architecture?

An architectural style that decomposes the system into small, independent services that communicate through APIs.

What is Service-Oriented Architecture (SOA)?

An architectural style that designs the system as a collection of loosely coupled services interacting through standardized protocols.

What does Modularity mean in system design?

Breaking down the system into smaller, manageable components or modules that can be developed and maintained independently.

What does Scalability mean in system design?

Designing the system to handle increased load and data volume without significant performance degradation.

What does Interoperability mean in system design?

Ensuring that different systems and components can work together seamlessly, even if they are built on different technologies or platforms.

How does IBM define Enterprise Architecture (EA)?

A tool that links the business mission and strategy of an organization to its IT strategy.

What are the six basic elements of Enterprise Architecture represented by P.O.L.D.A.T?

Process, Organization, Location, Data, Application, and Technology.

What are the four primary domains of Enterprise Architecture?

Business Architecture, Application Architecture, Data Architecture, and Technology Architecture.

What is Enterprise Information Architecture (EIA)?

A component of enterprise architecture intended to provide a common framework for the cost-effective sharing of data across different organizational units while ensuring security and privacy.

What three core goals drive Enterprise Information Architecture (EIA)?

Alignment, agility, and architecture.

What is the Zachman Framework?

A framework for organizing and categorizing information architecture that provides a matrix of six architectural perspectives and six aspects.

What is TOGAF (The Open Group Architecture Framework)?

A framework for developing and managing enterprise architectures that utilizes the Architecture Development Method (ADM).

What is IT Governance?

The structures, processes, and practices used to direct and control an organization's IT activities to align IT strategy with business strategy.

According to the provided diagram, what five key domains surround IT Governance?

Strategic Alignment, Value Delivery, Risk Management, Resource Management, and Performance Measurement.

What two core issues are addressed by implementing the GEIT framework?

1. Ensuring IT delivers value to the business. 2. Ensuring IT risks are managed.

In the Essential Meta Model, what is defined at the Conceptual Layer?

Where 'what' Information and Data is used or required by the business is defined.

In the Essential Meta Model, what is defined at the Logical Layer?

Where 'how' the Information and Data is used or represented in the organization is defined.

In the Essential Meta Model, what is captured at the Physical Layer?

Where 'where' the Information and Data is stored is captured.

What is an Information Concept in the Essential Meta Model?

The fundamental information elements that capture the type of Information items used in running the business, providing semantic grounding for logical and physical items.

What is a Data Subject in the Essential Meta Model?

High level, conceptual elements that capture the type of Data items used to deliver the information required to run the business.

What is an Information Representation?

An element describing how an Information View is represented using a specific technology, such as a Database, a Feed, or a Report.

What is a Data Object?

Defines a logical grouping of data attributes that are used across organizational processes to deliver information.

What is an Information Store?

Defines a physical deployment of an Information Representation and captures its deployment role (e.g., Production, Development, Test).

What is a Physical Data Object?

Defines the physical data that is stored in an Information Store.
