Module 2, Loading and storing data sources
learning objective: How to configure data sources in a GeoDMS project
In module 1 we discussed the basic concepts of the GeoDMS. Now we go back to the main workflow in most projects.
The GeoDMS is intended to model with data, not to collect it. We usually we start with loading (reading) data from one or more sources. The GeoDMS calculates results, which then could be stored (exported) in new files.
In this module you will learn how to configure relevant data sources to read data from or to write data to.
Loading (or reading) data is done by configuring a connection from a data item to a data source(file/database). If the data from the source is needed for a calculation or visualisation, the GeoDMS will load the data from the source in the memory of your machine.
Storing (or exporting) data is also done by configuring a connection from a data item is to a data source, but also an expression need to be configured for the with the storage configured. The results, if requested (e.g. in a map/table view), are calculated, presented and exported to the configured data source.
For both loading and storing data, we use a software component, called a StorageManager.
In the following three modules you will learn how to configure data sources for:
Module 2A, Loading different data sources
Module 2B, Storing different data sources
Module 2C, GeoDMS own data formats
