Data Access Intuitive ToolsScheduled Processes

MergingWhen your data is scattered in multiple datasets, merging allows you to combine the relevant parts of those data sources to create a new dataset.

AppendingStacking two datasets to create one larger dataset is called appending. When appending data, the datasets typically contain the same (or very similar) fields.

FilteringBy filtering a dataset, you are narrowing it down to just a specific group of records.

DeDupingTo dedupe is to remove duplicates from a dataset. Selection rules can be made to dedupe on specific conditions.

Data CleansingTo cleanse a column is to edit or replace values within the column cell.

RenameRenaming allows you to enter a new name for your columns.

TransformingTo transform a column is to perform an operation that creates a new outcome — this could be a new variable entirely, or a different version of the original column.

AggregatingAggregating allows you to select specific variables and calculate summary statistics.

TransposingBy transposing you can turn your rows into columns.
