Explanation: The concept of a software component forms the basis of the Service Component Architecture (SCA) programming model. A component is a unit that implements
some logic and makes it available to other components through an interface. A component may also require the services made available by other components. In that case, the
component exposes a reference to these services.
In SCA, every component must expose at least one interface. The assembly diagram shown in Figure 1 has three components. Each component has an interface that is represented by the
letter I. A component can also refer to other components. References are represented by the letter R. References and interfaces are then linked in an assembly diagram. Essentially,
the integration developer "resolves" the references by connecting them with the interfaces of the components that implement the required logic.

4. Component Modeling


Correct Answer : Get Lastest Questions and Answer :
Explanation: The architecture of a system is its 'skeleton'. It's the highest level of abstraction of a system. What kind of data storage is present, how do modules
interact with each other, what recovery systems are in place. Just like design patterns, there are architectural patterns: MVC, 3-tier layered design, etc.

Software design is about designing the individual modules / components. What are the responsibilities, functions, of module x? Of class Y? What can it do, and what not? What design
patterns can be used?

So in short, Software architecture is more about the design of the entire system, while software design emphasizes on module / component / class level.

Hence, hiding the complexity of Legacy component is an architecurl decisoon.

Explanation: A viability analysis is an analytical exercise. Using research, experience and business principles, it will determine the probability of the project to
sustain itself, grow, meet the objectives of the project and offer the expected returns of the investor.

The outcome of this analysis, may vary depending on who you speak to, and it's only a 'guesstimate'. Make sure you get advice from someone with expertise in your area of business,
as well as all the other issues to consider, such as the location of the business, competitors based in the area and the market for your product or service.

Question : You have been given a below scenario. You have in total TB data. Your data scientists have written queries to access this data.

However,

- Out of 1000 queries 850 queries, access 25 TB data
- Out of 1000 queries only 100 queries will touch 25 TB data out of remaining 75 TB data
- Out of 1000 queries only 50 queries will touch 20TB data out of remaining 50 TB data

Hence, you can say 850 queries are frequently accessing 25TB data.
