A graph is a data structure made up of nodes connected by edges. Edges can be directed or undirected. The number of edges entering a node is its indegree; likewise, the number of edges leaving a node is its outdegree. A set of edges that allow traveling from one node to another is called a “path.” The most common way to model a graph in Structured ...

Introduction to SQL and SQL Developer
2014This is the first chapter with real SQL statement examples. It thus would be beneficial for you to have access to an Oracle database and a schema with the seven case tables introduced in Chapter 1 and described in detail in Appendix A. You can find the scripts to create that schema in the download hosted from this book’s catalog page or the Source Code

Before I start talking about how to write queries for complex scenarios, I want to focus on how to write good T-SQL. This is not about writing code that performs well. This is about writing T-SQL code that reads well. I want to go over how to write code so that it is easily readable to others and to yourself.

Current Geographic Information Systems (GISs) are inadequate for performing spatial analysis, since they force users to formulate their often vague requests by means of crisp selection conditions on spatial data. In fact, SQL extended to support spatial analysis is becoming the de facto standard for GISs; however, it does not allow the formulation of ...

Congratulations! You are on the brink of learning how to build APEX web applications. But before you can begin, you need an APEX account. There are several ways to obtain an account: you can register for a free account through the apex.oracle.com web site; you might be given an account to an APEX server at your job; or you can even install an APEX ...

In the earlier chapters in the section on “Building Understandable T-SQL,” I have covered the various data types available and how to select the correct data type. I have also discussed several database objects available when you write your T-SQL and the pros and cons of using each database object. In the previous chapter, I explained the importance of
