In a DSS workflow, a SQL pipeline is a procedure that mixes numerous subsequent recipes (each using the same SQL engine). Then, a single job activity containing these integrated recipes—which may be both visual and "SQL query" recipes—can be executed. Typically, a SQL query will be converted into an expression in relational algebra, which is a series of relational operations. If we do one operation at a time, we incur too much cost because we need to create temporary files on a disc to store the outcomes of these temporary operations. Large temporary files must be created and stored on ... Read More
