This section briefly explains the fundamentals of business intelligence and data warehousing in general. It is important to understand the overall architecture and data flow for implementing Retail Insights.
Business intelligence includes the processes, methods, and technologies adopted by organizations to answer complex business questions and for building comprehensive decision support systems. These systems help organizations in maintaining secure, conformed, and highly available data for all levels of users from top executives who make decisions based on corporate level information to managers/analysts who analyze their area and take actions based on the information.
Business intelligence is built using several processes and applications that maintain these processes by adopting latest tools and technologies. One of the main components of business intelligence is a data warehouse. A data warehouse is the repository that stores the data extracted from several source systems and modelled to perform for data loading, reporting, and ad-hoc analysis needs.
Retail Insights uses sophisticated techniques to populate the data warehouse. Explained in greater detail throughout this guide, these techniques include taking the data provided by Oracle Retail Data Extractor (RDE) and then rapidly transforming that data and loading it into the data warehouse. Techniques used to load data into the warehouse vary depending upon whether the data consists of facts or dimensions.
There are several fact and dimension tables in the subject areas available in Retail Insights. Some examples of subject areas that exist in Retail Insights include Sales, Inventory Position, and Base Cost. Each subject area has its own data mart to support reporting and analytic needs. At the center of each data mart is fact data (note that fact data here corresponds to both base fact data and aggregated data). Facts are the transactions that occur in your data warehouse's source systems, such as RMS. You may want to look at sales transaction facts, inventory stock count facts at stores or warehouses, or inventory movement facts.
Facts have little meaning by themselves because they are usually just values (for example, six sales at a store, 15 items left at a warehouse, or 300 items transferred). What gives fact data true meaning is the intersection of dimensions in which facts exist. In other words, six sales on Wednesday at store B, or 15 dishwashers in stock last Monday at the Chicago warehouse, or 300 blouses transferred during the last week in February from the St. Louis warehouse to the Denver warehouse. Dimension data, therefore, exists in the data warehouse to serve as reference data to facts.
The following diagram illustrates data elements of a generic data mart and their inter-relationships:
