hello ... today morning light enough ... first hour accountancy law and 2 hours of computer science and religion finally ...

hour of computer science professor then we read a paragrafeto a book, the theme was: Development of software in the Software- last year cost more more. 'important that they have the following characteristics:
1) correctness;
2) flexibility;
3) adaptability;
4) utilities;
5) clarity;
6) efficiency;
7) reliability ;
8) robustness;
9) portability.

The cycle of creation of the software has the following phases:

4) testing
5) maintenance

VISIO - Microsoft's software is a costly, it can achieve the same result with excel. In software there are built-in manual (help linea7help online). Maintenance is the final step in the process of developing a software in which the software after releasing 60% of the cost of production is devoted to the latter. diagrams can be flow or block The first describes the physical flows of programming, the latter also called flowchart describing the logical flow of programming.
