if available, it is recommended to use the PRODUCT before considering COMPONENT, as a PRODUCT can consist of several components, which belong together, or are regularly used together to make certain functions working the right way.
Per example, the PRODUCT TradingNetworks consists of the components TradingNetworks and TradingNetworksArchive. Without the TN-Archive-component you will not be able to archive or delete your TN-data when it is no longer needed, except by recreating the schema.
BTW:
Before creating new schema, it is recommended to upgrade the DB-Configurator and its scripts to the latest fixes by using the UpdateManager.
