In particular, Chapters 8 and 9 cover spatial operators and functions that make it possible to cluster some of the steps in the example into single queries, making the process much simpler and more efficient. Storing Spatial Data in a Database Looking at vector data, we usually distinguish between the following: • Points (for example, the plots for sale in Figure 1-1), whose spatial description requires only x,y coordinates (or x,y,z if 3D is considered) • Lines (for example, roads), whose spatial description requires a start coordinate, an end coordinate, and a certain number of intermediate coordinates • Polygons (for example, a residential area), which are described by closed lines Figure 1-2 shows an example containing point, line, and polygon data.
With some attributes (area, perimeter, and population). qxd 10/2/07 4:20 PM CHAPTER Page 3 1 Spatial Information Management L ocation is an inherent part of business data: organizations maintain customer address lists, own property, ship goods from and to warehouses, manage transport flows among their workforce, and perform many other activities. A majority of these activities entail managing locations of different types of entities, including customers, property, goods, and employees. Those locations need not be static—in fact, they may continually change over time.
9 • It provides scalability, integrity, security, recoverability, and advanced user management features for handling spatial data that are the norm in Oracle databases but are not necessarily so in other spatial management tools. • It removes the need for separate organizations to maintain a spatial data infrastructure (hardware, software, support, and so on), and it eliminates the need for specific tools and skills for operating spatial data. • Through the application server, it allows almost any application to benefit from the availability of spatial information and intelligence, reducing the costs and complexity of spatial applications.
