Nielsen bapp02.tex V4 - 07/23/2009 5:01pm Page 1622 B Using the Sample Databases the easternmost point of North Carolina’s Outer Banks, known for incredible empty beaches and the graveyard of the Atlantic. Cape Hatteras Adventures leads wild and sometimes exotic adventures for the rich and famous. From excursions down the gnarly Gauley River in West Virginia to diving for sunken treasure off the Outer Banks to chopping through the Amazon jungle, Cape Hatteras Adventures gets its guests there and brings them back, often alive and well. The staff and management of CHA are outdoors folks, and their inclination to avoid the indoors shows in the effort that’s been put into IT. The customer/prospect list is maintained in Access 2000 in a single-table database. It’s used primarily for mailings. The real workhorse is an Excel spreadsheet that tracks events, tours, and tour guides in a single flat-file format. In the same page, a second list tracks customers for each event. Although the spreadsheet is not a proper normalized database, it does contain the necessary information to run the business. QuickBooks handles all financial and billing activities, and both the company president and the bookkeeper are very satisfied with that setup. They foresee no need to improve the financial or billing software. Application requirements CHA has grown to the point that it realizes the need for a better scheduling application; however, it desires to ‘‘keep the tough work in the rapids and not in the computer.’’ CHA has contracted for the development and maintenance of the database. All scheduling and booking of tours takes place at the main office in Cape Hatteras, North Carolina. CHA launches tours from multiple sites, or base camps, throughout the world. The base camps generally have no computer access and sometimes no electricity. Guides are dispatched to the base camp with a printed guest list. If it’s determined in the future that a base camp may need to be staffed and have access to the schedule online, a web page will be developed at that time. Each base camp may be responsible for multiple tours. A tour is a prearranged, repeatable experience. Each time the tour is offered, it’s referred to as an event. An event will have one lead guide, who is responsible for the safety and enjoyment of the guests. Other guides may also come along as needed. As CHA brings on more guides with broader skills, the database must track the guides and which tours each one is qualified to lead. Database design The database design uses typical one-to-many relationships between customer type and customer, and from guide to base camp to tour to event. Many-to-many relationships exist between customer and event, guide and tour, and guide and event. Concerning the development style, there is currently no need for multiple database sites, so identity columns will be used for simplicity of design. The primary means of access to the data is through views and direct SELECT statements. Data conversion The CHA2_Create.sql script creates an empty database. The data resides in the Access and Excel spreadsheets. Both the CHA_Conversion DTS package and the CHA_Convert.sql script can extract the data from Access and Excel and load it into SQL Server. 1622 www.getcoolebook.com Nielsen bapp02.tex V4 - 07/23/2009 5:01pm Page 1623 Using the Sample Databases B CHA2.adp front end Because the Cape Hatteras Adventures staff is comfortable with Access forms and does not require the robustness of a full Visual Basic or .NET application, a simple front end has been developed using Access.adp project technology. OBX Kites OBX Kites is a high-quality kite retailer serving kite enthusiasts and vacationers around the Outer Banks, where the winds are so steady the Wright brothers chose the area (Kill Devil Hills) for their historic glider flights and their first powered flights. OBX Kites operates a main store/warehouse and four remote retail locations and is planning to launchane-commercewebsite. Application requirements OBX Kites needs a solid and useful order/inventory/purchase order system with a middle-of-the-road set of features. For simplicity, all contacts are merged into a single table, and the contact type is signi- fied by flags. A contact can be a customer, employee, or vendor. Customers have a lookup for customer type, which is referenced in determining the discount. Full details are maintained on customers, includ- ing both a summer location and the home location. The product/inventory system must handle multiple suppliers per product, price history, multiple inventory items per product, multiple locations, and inven- tory transactions to track inventory movement. Database design The database design uses standard one-to-many relationships throughout. The database construction must support replication and Unicode for international customers. For per- formance and flexibility, the database implements two filegroups — one for heavy transactions and the other for static read-mostly data. The database design is a standard inventory, order-processing database. The Family This small database demonstrates multiple hierarchical reflexive relationships for interesting queries and both cursors and queries to navigate the genealogical hierarchy. Application requirements The Family database must store every person in the family, along with genealogical information, includ- ing both biological and marital relationships. The database is populated with five generations of a ficti- tious family for query purposes. Database design The Family database consists of two tables and three relationships, as configured in the Database Designer. Each person has an optional reflexive MotherID and FatherID foreign key back to the PersonID.Themarriage table has a foreign key to the PersonID for the husband and the wife. The primary keys are integer columns for simplicity. 1623 www.getcoolebook.com Nielsen bapp02.tex V4 - 07/23/2009 5:01pm Page 1624 B Using the Sample Databases Aesop’s Fables Aesop’s collection of fables is an excellent test bed for string searches and full-text search. The fables are relatively short and familiar, and they’re in the public domain. Application requirements The primary purpose of this database is to enable you to experience SQL Server’s full-text search. Therefore, the database must include a few character columns, a BLOB or image column, and a BLOC-type column. Database design The database design is very simple — a single table with one fable per row. 1624 www.getcoolebook.com Nielsen White & Parui The book you need to succeed!
