What is a function

In object-oriented programming, a class is an extensible program-code-template for creating objects, providing initial values for state (member variables) and implementations of behavior (member functions, methods).

What is a Class

Libraries are small pieces of code that can be reused in several places in an application of in multiple ones.

Frameworks are sets of libraries sometimes tight together to reduce the time we take to develop an application.

libraries and frameworks

MVC

MVVM

Each part of a program should be isolated from others, and have only one concern or a simple task that does very well.

Separation of concerns

The IT professional08

● Very neat profiles and CV.● Tend to highlight the previous experience● Use of formal language in CV, presentation

letters.● Leverage People and companies as

references

Different how?

● Often incomplete or very summarized CVs● Tend not to focus in the past (what was

done is in the past, focus on the next project/task)

● Use of colloquial language in CVs, rarely have presentation letters

● Provide references just on request

Regular person IT worker

● What process should I follow to execute this task?

● Something changed, let me ask what to do now?

● Have a problem, lets escalate this above.

Different mentality

● How can I automate this so I just do it once?● Something changed, how does this affects

me, how can I adapt or how does it work now?

● Have a problem, how can I solve this?

Regular person IT worker

● I have my tasks, I’ll do it the best I can as long as I’m told how.

● New things to learn, do we have trainning?● New techniques may appear once every 2

or 3 years, no daily effort needed.

Different Expectations

● I have my tasks, what can I do to be better?● Where can I learn more about this? is there

something better for the same task?● I got to keep up, 2 to 3 months is a lot to

catch up on.
