Learning the basics of a modeling technique is not the same as learning how to use and apply it. To develop a data model of an organization is to gain insights into its nature that do not come easily. Indeed, analysts are often expected to understand subtleties of an organization's structure that may have evaded people who have worked there for years.
Here's help for those analysts who have learned the basics of data modeling (or "entity/relationship modeling") but who need to obtain the insights required to prepare a good model of a real business.
Structures common to many types of business are analyzed in areas such as accounting, material requirements planning, process manufacturing, contracts, laboratories, and documents.
In each chapter, high-level data models are drawn from the following business areas:

While they were opposed and oppressed by some of their former associates, they were, on the other hand, reinforced by the accession of outstanding men, like Richard Cameron and Thomas Forrester, who, in their earlier years, had complied with Prelacy; and by others, like James Renwick, Patrick Walker, and Sergeant Nisbet, who were born after the persecution had actually commenced. Men, and even women, were found ready and willing to endure all hardships, and to brave an ignominious death, rather than relinquish or compromise the principles which they held so dear, and to which, as they believed, the nation was bound by solemn covenants. The story of religious covenanting in Scotland covers a long period. The covenants, or bands as they were frequently called, may be divided into three classes—public, semi-public, and private—and the influence of each has been felt at some of the most critical periods in the history of the country. The private or personal covenant, in which the individual Christian gave up himself, or herself, formally to the service of God, helped many a one to walk straight in crooked and trying times. These private transactions were neither less solemn nor less sacred because the knowledge of them was confined to the covenanter and his Lord.
Many specimens of these old personal covenants have been preserved, and they throw a vivid light on a type of earnest piety, which, it is to be feared, is rather rare in the present day. One of these came into my hands twenty years ago, inside a copy of Patrick Gillespie’s well-known work, “The Ark of the Testament Opened.” The book was printed at London in 1661, and is still in the original binding, but the old brown calf had given way at the joints, and so one of the previous owners had it rebacked. Fortunately, the binder preserved the fly-leaves, on which there are a number of jottings and dates; and on one of them there is a genuine personal covenant, written and signed by Francis Wark. He had written this covenant on that side of the last fly-leaf which was next to the board, and had then pasted the edges carefully down to the board, so that no one could see that there was any writing there. After being hidden for more than a century and a half, it was revealed by the binder.
