Applying and Extending Oracle Spatial

Overview of this book

Spatial applications should be developed in the same way that users develop other database applications: by starting with an integrated data model in which the SDO_GEOMETRY objects are just another attribute describing entities and by using as many of the database features as possible for managing the data. If a task can be done using a database feature like replication, then it should be done using the standard replication technology instead of inventing a new procedure for replicating spatial data. Sometimes solving a business problem using a PL/SQL function can be more powerful, accessible, and easier to use than trying to use external software. Because Oracle Spatial's offerings are standards compliant, this book shows you how Oracle Spatial technology can be used to build cross-vendor database solutions. Applying and Extending Oracle Spatial shows you the clever things that can be done not just with Oracle Spatial on its own, but in combination with other database technologies. This is a great resource book that will convince you to purchase other Oracle technology books on non-spatial specialist technologies because you will finally see that "spatial is not special: it is a small, fun, and clever part of a much larger whole".

Summary


In this chapter, we learned about the concept of Oracle partitioning and how it can be useful for managing tables with large numbers of rows. We explained how Oracle Spatial supports the partitioning concept for the spatial index. The different types of partitioning models are also covered that are suitable for different types of applications. We showed examples of performance gains that can be obtained during index creation and query time using partitioning. The question of when to use spatial partitioning and non-spatial partitioning is also addressed in this chapter. In addition, we also described the best practices for ingesting large volumes of spatial data with the help of partitioning.

In the next chapter, we'll learn how to use Oracle Spatial capabilities to solve real world problems. We'll see how to access and work with different properties and attributes of the SDO_GEOMETRY object and describe several PL/SQL functions and procedures to extend the functionality provided...
