For example, timestamps can be used whether or not the data is being unloaded to a file or accessed through a distributed query. Since this extraction displays all the info at present out there on the source system, there’s no must hold observe of modifications to the information supply since the final successful extraction.
Data extraction doesn’t necessarily imply that entire database buildings are unloaded in flat information. In many cases, it might be applicable to unload entire database tables or objects. In other cases, it could be extra appropriate to unload solely a subset of a given table such because the changes on the supply system because the last extraction or the results of joining multiple tables collectively. Different extraction methods range of their capabilities to support these two situations. Some supply techniques might use Oracle range partitioning, such that the source tables are partitioned alongside a date key, which allows for simple identification of latest data.
The extraction process can connect directly to the source system to entry the supply tables themselves or to an intermediate system that shops the info in a preconfigured manner . Note that the intermediate system is not essentially physically completely different from the source system. The extraction technique you need to select is extremely dependent on the supply system and in addition from the enterprise needs within the goal data warehouse environment.
