Users

User creation form

When clicking on the edit or New user buttons, a form pops up on the screen. The information necessary to create a user consists of a Username, Name, Middle name, password and the person's Role within the app. This Role will determine the functionalities available to the user. A note, without any effect in the behavior of the application can be added to indicate any relevant information to the system administrator.

This same form allows the system administrator to modify the password of any user. For security reasons, this password must contain some number, some capital letter, some small letter, and at least eight characters.

Since they are used to audit changes in patients and requests, users cannot be deleted. However, they can be declared not to be active, which would prevent them from logging in, but still keep track in the database of all their past actions.

Access log

The access log shows the user which user has done an action within the app and exactly when. The timestamp is in the format Year-Month-Day Hour:Minute:Second

Downloaded fields

The application permits the user to download certain documents into the computer.

Summary of instances

Summary of instances

This tab displays information about the different existing instances in the application. Some examples are: the number of patients, users, requests or genders. This information comes directly from the database and is automatically updated after every modification in the application. To facilitate the reading and identification of the different kinds of instances, the information is divided into three sections: Data, Administration and Configuration.

Roles

This tab is displayed and works, in the same way as the state of the request tab in the Configuration functionality. The roles are unchangeable, but their labels (not the corresponding functionality) can be customized.

Each role has different actions allowed within the application, chosen due to the tasks the people are expected to carry out. Thus, there are three roles within the app, which indicate the functionalities that a user can perform, as can be seen in the following table.

Parameters

Parameters determine the behavior of some functionalities. Thus, they cannot be created or deleted. However, their values can be updated to customize the system. At this point it is important to highlight the on updating them, the data type must be respected. Providing a value of the wrong data type (e.g., a string instead of an integer) can provoke the malfunction of the whole application.
