This is part of System Modeling and Design:

This is a software system for collecting, transforming and visualising food production, imports, exports and logistics data across Europe

The system automatically collates or updates data from multiple sources through native system integrations. It specifically collects data on:

The production quantity of a basket of food items.

The import quantity of the food basket.

The export quantity of the food basket.

The location of food production, import and export

The routes of export and import and the quantities of production, import and export of the food basket.

The system transforms these disparate data sources into a single database and creates a dashboard that allows that data to be visualised in a time series, bar charts and a map overlay $($later$).$

The principal features to be covered by the software systems are:

Data collection

Data transformation

Data visualisation
