A schema parser may determine one or more datasets of a database schema, wherein the datasets include one or more fields from a data source and represents data corresponding to the one or more fields. An input handler may receive a selection of one or more of the datasets via an interface. A translation engine may provide operations for refining the data of the selected datasets into a result set via a query, wherein the operations may be determined based on metadata defining relationships amongst the data sources and fields. A query engine may provide a graphical query including operational flow indicators indicating a directional flow of the query from the selected datasets with the selected operation to the result set.
