Most organizations do not rely on a single database configuration to be followed across the board. The purpose of having multiple database configurations and settings is similar to the principle of hedging or diversifying risk – the multiple configuration serve as barriers to employees who wish to internally cause damage, collect data about the company or use the information for unauthorized purposes (like selling to a third party). Multiple database configurations can come in various forms: having dedicated database servers, multiple platforms like SQL, Oracle and MySQL and a mix of the above. The idea is that organizations and their IT managers feel safer when information and their data sources are scattered across various configurations. This allows them to reduce the risks of data losses and hacking. The former is avoided because if there is a data failure, then it is likely to be restricted to the particular configuration only due to the fact that multiple configurations are often needed to be enforced across different physical data sources. As for hacking it is important to have different configurations because it restricts the success of hackers, viruses and other automated attempts to gain unauthorized access to data.
