The VIRGIS system is a map-based analytic system which enables the analysis of the business processes in the given geographical distribution. The processes to be examined can be selected arbitrarily. Typical areas are the sales, storage, transportation, production, but the circle can be expanded depending on the situation.
The system aims to present the data aggregated for the user, in a graphical form – which could be easier understood – instead of using the traditional list or tabular views. However, it is also possible to look behind the trends, looking the details as well.
The system has two main components: data store and visualization layer:
It is a storage layer developed for the given specialty, optimized for analysis with following types of information:
- The analytics aspects typical for the specialty, e.g. customers, products, sales units. The analysis focuses on the aspects which have geographical references, thus which have address data.
- The numerical data typical for the specialty, of which order of magnitude’s representation the trends can be analyzed. E.g. amount of sales, value of stocks. These are the measures.
For the geographically related data are mostly cities available.
The system includes the country's administrative hierarchy: country -> region -> county -> district-> city. It can be linked to all addresses’ data.
It is the system interface, with which the user meets. It is an interactive interface where the user can look and analyze the data area developed in the system and the data of the specialties. In the visualization layer can be made other simple interactive operations on the preconceived views. On a higher level the views’ configuration setting can be changed, so the customer can reform the displayed content and the view.
The visualization layer contains the following options:
Following from the basic function of the system the main displayer layer is the map, of which role is displaying the data according to their geographical location. The system supports thematic representation, it means, that on the basic map, which shows the location of each geographical unit, can be represented the specialty’s numerical data in a chosen form. The treatment of the special thematic layer is the system’s special developed service. According to the settings the data representation can be field-based coloring, circle, diagram, and scatter. On the geographical units special operations can be performed: drilling down to smaller geographical units, looking the data and the details. The interactive interface ensures looking further splitting, details either with graphical or tabular views behind the aggregated information.
Beside the maps it is possible to present visually such analytics aspects, which do not have geographical attributes. These can be filtered, and according to these aspects the data can be further split. On more points of the system are graphs, diagrams representation methods, e.g. donuts, bar, area, tower, column, pie, line, scatter. The representation of the graphs can be implemented on the map, on a detail appearing by a click, or on an additional screen block. Depending on the graphs’ type, the diagram has one or more dimensions. These can be selected by the configuration settings. The index can be selected as well, and it can be represented in the graph..
The data can be viewed behind all screen blocks. These include in aggregated, tabular form the displayed content. In addition, there is a tabular screen block, where the details can be viewed. The elaboration depends on, that on what level are stored the transactions of the given area in the data store. For example, in case of sale the invoice is the smallest available level. The columns appearing in the chart can be selected during the configuration, and the grouping aspects and the order can be set as well. The tabular content will be always displayed depending on the filters set for the other objects of the screen. The records can be exported into various formats..
The basic data content can be further filtered in a complex way to reach the desired content.
• Filter according to the geographical hierarchy
• Filter according to the date
• Primary and secondary filters
The set filters affect all blocks of the screen, so it must be taken into consideration. In case of an unwanted filter the condition can be deleted.
