Staging area architectures range in complexity from a set of simple relational tables in a target database to self-contained database instances or file systems. [4] Though the source systems and target systems supported by ETL processes are often relational databases, the staging areas that sit between data sources and targets need not also be ...
The respective tables of data were generally developed by using the more complex transfer function method to determine the various cooling loads for different types of heating. [ 2 ] [ 3 ] The results gained by doing so are then normalized for each type of heat gain used for the tables, CLTD, CLF, and SCL.
A database relation (e.g. a database table) is said to meet third normal form standards if all the attributes (e.g. database columns) are functionally dependent on solely a key, except the case of functional dependency whose right hand side is a prime attribute (an attribute which is strictly included into some key).
