Question:

Consider a local car dealership that has been in business for fifteen years or \(\mathrm{so}\). In addition to selling and leasing new and used cars, the dealership has a parts department, service department, and auto body department. It was one of the first car dealerships to automate in the mid-70s, and while most of the information systems have been periodically updated, a few of the criminals systems are still in use, including some stand-alone systems. About five years ago, the dealership began to gradually replace some of the traditional file-based systems with at relational database system, but the conversion is far from over. Last year, the owner read in an airline magazine about data warehouses, und hired a local systems integrator to install one, which is in progress. The dealership has a couple of jack-of all-trades IT people on staff, but most of the development work is contracted out Given this scenario, draw a high-level diagram of whit the dealership's data architecture might look like; use Figure \(14-2\) as in example.
