• Application software: are the programs we use on a daily basis, such as web browsers, text editors, messaging apps and games.

To develop software, you need to program - in other words, writing code using programming languages. There are different areas within development, such as programming front-end vs. back-end, These determine which parts of the software a professional works on.

The developers software can also act in different ways:

• Front-end: trabalha na interface e na user experience, garantindo que os sites e aplicativos tenham um responsive design e funcional.
• Back-end: focuses on the logic of the system, servers and database, ensuring that everything works correctly behind the interface.
• Full-stack: works on both the front-end and back-end, and is responsible for the complete development of a system.

Stages of the Software Development Cycle

The software development cycle is a set of steps that guide the creating a system, This ensures that it is planned, developed and tested efficiently. This process is essential if the software is to meet user expectations and function correctly. See the main phases of this cycle:

Analysis

The analysis phase involves gathering software requirements. At this stage, the developers and stakeholders define what problems the system should solve, what functionalities it needs to have and what the end user's needs are.

Design

This is where the software is structured. The design includes the system architecture, user interface and database planning. This planning ensures that the software has a well-organized structure and is scalable.

Program

The programming phase is where the code actually starts to be written. Developers use programming languages and frameworks to transform the plan into a functional system. This stage can be divided into front-end, back-end and database, depending on the complexity of the software.

Here's an example of code for an online store:

This code covers the basic functions: adding, removing and listing products. Simple and functional for illustrative purposes!

Tests

Testing is essential to ensure that the software works correctly before it is released. In this phase, unit, integration and usability tests are carried out in order to identify and correct flaws in the system.

Maintenance

After launch, the software enters the maintenance phase, where possible errors are corrected and new functionalities can be added as required by users. This stage is essential for keeping the software up-to-date and efficient in the long term.
