IT arch Flashcards
The IT Architecture has four components. Which ones are they?
A) Architect
B) Architecture
C) Systems
D) Architecture methods
A) Architect
B) Architecture
D) Architecture methods
Systems isn’t listed as one of the four components in the provided document.
In the data architecture, there are three key operations. Which of the following are the key operations on the data?
A) Data acquisition
B) Data formation
C) Data analysis
D) Data delivery
A) Data acquisition
C) Data analysis
D) Data delivery
While Data formation might be loosely interpreted as structuring or organizing data, it’s not a standard term like the others.
Choose the right answer from the follow to fill the gaps. The information system of an enterprise is a collection of activities that regulate the … and … of information and the storage of data that are relevant to the management of the enterprise.
A) Sharing, distribution
B) Operating, distribution
C) Sharing, formatting
D) Formatting and operating
A) Sharing, distribution
These terms accurately describe the key functions of information systems in regulating the flow and accessibility of information within an enterprise.
Explain why the conceptual modelling (design) cannot be automated or helped by automatic tools.
Conceptual modeling requires human creativity and understanding of complex concepts, making it challenging to fully automate with precision or replicate effectively using automatic tools.
What are the key differences between conceptual model and logic model?
Conceptual models represent ideas or concepts, while logic models describes specific processes and outcomes.
Which ones of the following are qualities to measure the conceptual models?
A) Simplicity
B) Expressiveness
C) Performance
D) Formality
A) Expressiveness
B) Simplicity
D) Formality
Performance is more relevant to physical models and actual system implementations where the efficiency and speed of the system are critical.
Use an example to explain what minimal cardinality and maximal cardinality are in the ER model.
Minimal cardinality (0 or 1) indicates the minimum instances of an entity in a relationship, while maximal cardinality (1 or many) indicates the maximum allowed instances.
Which of the following is the right answer if there is a generalization relationship from Entity E1 to Entity E2?
A) All the instances of E1 belong to E2.
B) All the instances of E2 belong to E1.
C) E1 is the same as E2.
D) If an instance belongs to E2, it does not belong to E1.
A) All the instances of E1 belong to E2.
When there’s a generalization relationship from Entity E1 to Entity E2, it typically means that E1 is a specialized version of E2. Therefore, all instances of the specialized entity (E1) also belong to the more general entity (E2).
Choose the right one from the following that gives the main elements of the (finite) state machines?
A) States and transitions
B) Workflow and process
C) State and process
D) Workflow and transition
A) States and transitions
FSMs consist of a finite number of states and the transitions between those states that occur in response to external inputs. This option correctly identifies the two fundamental components of a finite state machine.
Which ones of the following are described in an objective (goal) model?
A) Reasons
B) Goals
C) Problems
D) Processes
A) Reasons
B) Goals
C) Problems
Processes are not typically described in an objective or goal model. While processes are crucial in how an organization or system operates and are deeply connected to achieving goals, they are generally considered a separate aspect and are more detailed in nature.
Which of the following are constructs of the Dataflow Diagram (DFD)?
A) Process
B) Entity
C) Dataflow
D) Interface
A) Process
C) Dataflow
D) Interface
DFD contains three constructs: process, dataflow, and interface.
Explain what a dataflow is in the Dataflow Diagram
In Dataflow Diagrams, a dataflow represents the movement of data between processes, data stores, and external entities, illustrating how data is input, processed, and output in a system.
Which ones of the following are described in an objective (goal) model?
A) Reasons
B) Goals
C) Problems
D) Processes
A) Reasons
B) Goals
C) Problems
Processes are more related to the functions and activities of the enterprise.
Objectives model: describing the reasons and motivations for developing an information system; addressing goals, problems, etc.
Choose the right one from the following to fill the gaps. A stakeholder is an individual, team, or — with interests in, or — relative to a system.
A) Organization, concerns
B) Organization, interests
C) Process, concerns
D) Processes, interests
A) Organization, concerns
A stakeholder is an individual, team, or organization with interests in, or concerns relative to a system. So, the most fitting option based on general understanding would be: Organization, concerns
An enterprise architecture process consists of four steps. Which are they?
A) Design
B) Management
C) Programming
D) Use
A) Design
B) Management
D) Use
Bonus: Plan
Programming is more related to the specific implementation of software solutions within the broader context of an enterprise’s IT architecture.
