INTERNAL DATA
Internal data node allows to read the record / records from the internal database based on the value of the key transmitted in the scenario.
The engine allows you to store internal data collections for decision-making scenarios. Typical applications are:
Storing dictionary data, black lists
Auxiliary structures for scenarios (cross-check)
Storing large behavioral datamarts
Creation, power supply, data modification is possible via the engine's API. The methods are:
Creating a collection
Loading data to the collection
Manipulations on individual records (delete / add)
Managing of the data is possible from the main menu -> Internal Data
To add a database, define join conditions: Join variable, Data collection (name of the database) and Data index. After selecting a database, in the Columns section a list of database columns will be presented. For each column user can decide, whether it will be included in the scenario. In the node user also defines merge type of variables added by this node, a prefix of these variables and whether results will be limited to one row.
Specific parameters:
Join variable - a variable from the scenario containing the value of the connection key
Data collection - the name of the collection / data set
Data index - index in the set after which we combine
Columns - list of selected variables from the set
