Data Acquisition (video)

Summary

Summary

The goal of the Data Acquisition phase is to establish connections to data sources, managing the size and speed at which the raw data changes.

In DSS, a dataset is any piece of data in a tabular format.  DSS remembers the location of the original external or *source *datasets. The data is not copied into DSS. 

According to the visual grammar of DSS, blue squares represent datasets, and the icon represents the storage system. 

DSS Plugins can be used to create custom visual connectors for any APIs, databases, or file-based formats. 

DSS automatically infers both the file format and the schema of a data source.  Each column in DSS has both a storage type and a high-level meaning.
