Front-end or User Interface
Interfaces have been developed taking into account: intuitiveness, easy understanding
and relevant information. Some of the requirements elicited where taken into account
in the development of a set of interactive visualization interfaces that allow for:
information roll-up and drill-down, queries and reports creation, KPI management,
monitoring and alerting, filtering, among others. Development of analytical
processing was carried out on top of QlikView application enabling web-based access
and horizontal scalability. By using this tools, automatic alerting is enabled, as well as
the capacity for self-adaptation to the end user device, being it a mobile or fixed
platform, making it truly pervasive.

Architecture for Local Government Platform
The BI solution architecture was developed in order to ensure compliance with real-
time requirements and the characteristics of pervasive BI [17]. Thus, as can be seen in
the Figure 3, the architecture consists of two machines, one responsible for the
operational management of DW and ETL process and another responsible for the user
front-end. The front-end is web enabled, so it can be accessed by the usual devices
and technologies used for web access, allowing access to data anywhere and anytime.

The solution ensures the freshness of the data by means of a connection from the
DW to the organizational database. It was designed to be as autonomous as possible
and be available on any web enabled device with internet access.
The main features of the solution are: Real-time data; Online access; Context
awareness; Automatic tasks; Security of information (access control, confidentiality,
personal data law compliance); Adaptive environment: Horizontal scalability. The
architecture contains all the necessary requirements to be considered as a PBI.
