Question: While there is typically only one conceptual (or logical) and physical (or internal) view of the data, there can be any number of different external views. This allows users to see database information in a more business-related way rather than from a technical, processing viewpoint. For example, a financial department of a company needs the payment details of all employees as part of the company's expenses, but does not need details about employees that are the interest of the human resources department.

Try to answer this question if possible: How many conceptual or physical views of data are there?
Answer: one
Question: IBM acquired Kenexa (2012) and SPSS (2009) and PwC's consulting business (2002), spinning off companies like printer manufacturer Lexmark (1991), and selling off product lines like its personal computer and x86 server businesses to Lenovo (2005, 2014).

This transition had progressed as of early 2015[update].
