A system and method selects rows from a fact table in a dimensional database containing a fact table, a time dimension table and other dimension tables. The other dimension tables each contain rows containing a time invariant attribute to identify an item described by the row, an effective time attribute for the row, and other attributes. If an attribute for an item changes, a new row is added to the dimension table containing the time-invariant attribute for the item and current attributes for the item, without deleting or overwriting any existing rows for that item. Such dimension tables can be selected or used to create other tables using one or more time attributes of the dimension tables. The tables created can be selected or used to create still other tables using one or more time attributes of those tables. One or more of the resulting tables or one or more tables created from a resulting table are then joined to a table in the dimensional database or a table created from a table in the dimensional database.

Simplified heat-treatment in making aluminum alloys castings of the type improved by aging, especially for automotive engine cylinder heads and motor blocks. The castings, after solidification and extraction from their molds, each have an end product (workpiece) portion and a riser portion (the latter being ultimately cut off as waste). The workpiece portion of the casting is selectively quenched from solution temperatures down to about 120° C. by spraying water or other appropriate liquid preferably as a gas driven mist onto the surfaces of the workpiece while maintaining the riser portion of the casting essentially unsprayed at relatively significantly higher temperatures. After the quench, the residual reservoir of heat thus retained by said riser portion, by internal heat conduction, reheats the workpiece portion and maintains such workpiece portion for an effective time period within the temperature range for artificial aging, thus obviating any need for the aging furnace used by the prior art. Preferably, the quench is immediately after the casting mold extraction (without the standard natural cooling, reheating, and solution heat-treatment, all prior to quenching), thus obviating also the need for a solution heat-treatment furnace, required by the conventional prior art.
