Statistical analysis reporting data mining and others that allow the processing of information for specific purposes tools enabling the presentation of data in the form of simplified visualizations. It is worth knowing that the architecture of a data warehouse may vary depending on the size of the database itself and the needs of the organization. There are usually several layers of information within a data warehouse. These are: data sources that reach the system these are all files or smaller relational databases that are "thrown" into the warehouse and then processed and unified. These can be for example text files XML files spreadsheets and many other data formats; a central data warehouse i.e. a place where this information is organized and classified so that it can be subjected to further analytical processes.
The central warehouse is regularly updated so that the data warehouse provides current information operational data warehouse this is a kind of buffer zone of the data warehouse where they are preprocessed to relieve the central data warehouse and ensure more efficient Email Marketing List functioning of the entire system. It is also worth knowing that operational data stores are updated with new information more frequently than the central warehouse but the data is only stored there temporarily; thematic warehouses they contain fragments of all data reaching the warehouse which are "oriented" to a specific aspect of the organization's activities.
They may concern for example sales warehouse resources human resources settlements and finances etc. They are therefore tailored to the needs of individual units and departments of the company and allow for a more detailed look at individual areas. Although the diagram presented above quite precisely defines the functioning of almost every data warehouse it is worth remembering that individual solutions may have different architecture. Most often in the context of data warehouse architecture there are three basic types of implementation.
