COLLECTION_vector_GROUP_OF_ATTRIBUTES
+- In case of a vector attribute, a table should be created with its name indicating the name of the Collection and the name of a group of the attribute, separated by `_vector_`, such as `COLLECTION_vector_GROUP_OF_ATTRIBUTES`. - The table must contain a Column named `id` and another named `vector_index`. - There must be a Column named after the attributes names, which will store the value of the attribute for the specified element `id` and index `vector_index`. @@ -135,9 +133,7 @@ CREATE TABLE HydroPlant_vector_GaugingStation( ### Time Series Files - All Time Series files for the elements from a Collection should be stored in a Table -- The Table name should be the same as the name of the Collection followed by `_time_series_files`, as presented below - -COLLECTION_vector_ATTRIBUTE

+- Time Series stored in the database should be stored in a table with the name of the Collection followed by `_time_series_` and the name of the attribute group, such a `COLLECTION_time_series_GROUP_OF_ATTRIBUTES`. Notice that it is quite similar to the vector attributes, but without the `vector_index` column. Instead, a mandatory column named `date_time` should be created to store the date of the time series data.
