How To: Loading Data in SAS Visual Analytics - Overview
Data can be loaded into Visual analytics LASR servers either by importing from an external source or by using a SAS dataset. The latter can be either from a pre-existing dataset or from one that is created from a query within Visual Analytics. Loading data also requires SAS to have the applicable metadata available for each dataset.
For external or pre-existing SAS datasets, some steps need to be taken the first time a dataset is loaded to ensure that this metadata is associated with the table. This process is called ‘Registering a table’. The other options generally do not require registering a table.
Other load options include Autoloading (where SAS scans an original dataset and when a change is detected, automatically reloads the data into the LASR server to capture the changes) and Reload-on-Start (where tables from certain libraries are reloaded automatically each time the server starts).
Autoloading is specifically useful for dynamic datasets that are subject to constant data updates, whereas Reload-on-Start is very useful for datasets that may have been imported into the LASR server manually by the user.
