These are examples of continuous time stochastic processes (Hoel, Port and Stone, 1972). 7 Further reading This chapter introduced the organisation and structure of databases for data mining. The most important idea is that the planning and creation of the database cannot be ignored. They are crucial to obtaining results that can be used in the subsequent phases of the analysis. I see data mining as part of a complete process of design, collection and data analysis with the aim of obtaining useful results for companies in the sphere of business intelligence.
