when a new version of Netscape Navigator came out, setting the text of the radio button to null not only didn t work, but also actually caused the browser to end hard, displaying an error message referencing some C++ source code So much for Java s crossplatform compatibility In the beginning of the PC revolution, cross-platform compatibility was a much bigger requirement With so many slightly different variants of PCs, as well as other platforms, having a single development environment was very important Several circumstances have minimized this issue First, Intel x86 assembly code has become close to a universal assembly language Virtually any application of any significance these days is available for an Intel-based machine Even other hardware platforms, notably the Apple Macintosh, provide emulation environments that allow Intel-based applications to run.

I also urge you to look up Vadim Tropashko's Nested Intervals model at http://www.dbazine.com. It is a beautiful model, very interesting intellectually, and Vadim covers practical issues such as implementation and performance. However, I find Vadim's model to be substantially more complex than most mere mortals (including me) can grasp in full, so I won't cover it here. The solutions I will cover here, on the other hand, will be fairly simple to understand and implement by experienced T-SQL programmers. Before you make an attempt at reading Vadim's stuff, make sure you have enough coffee and enough hours of sleep.

The explanations in this section are based on definitions from the National Institute of Standards and Technology (NIST). I made some revisions and added narrative to the original definitions to make them less formal and keep relevance to the subject area (T-SQL). For more complete and formal definitions of graphs, trees, and related terms, please refer to: http://www.nist.gov/dads/

The second important change that has affected the issue of cross-platform compatibility has been the explosion of the Internet The Internet provides a single platform that allows applications from a variety of platforms to work on virtually any other platform, including even the newer ones, such as wireless devices For many applications, HTML, along with client-side JavaScript, provides a rich enough environment Of course, in some places, the Internet boom has increased the requirement for cross-platform execution notably in creating richer user interfaces on the client side and here s where Java has found a place As I mentioned at the beginning of the chapter, another difficulty for software developers today is enabling the various pieces of an application written in different languages to communicate Currently, a number of languages and technologies are used on the dominant platform (Microsoft Windows running on an Intel processor).

A graph is a set of items connected by edges. Each item is called a vertex or node. An edge is a connection between two vertices of a graph. A graph is a catch-all term for a data structure, and many scenarios can be represented as graphsfor example, employee organizational charts, bills of materials (BOMs), road systems, and so on. To narrow down the type of graph to a more specific case, you need to identify its properties: Directed/Undirected In a directed graph (also known as a digraph), there's a direction or order to the two vertices of an edge. For example, in a BOM graph for coffee-shop products, Latte contains Milk and not the other way around. There's an edge (containment relationship) in the graph for the pair of vertices/items (Latte, Milk), but no edge for the pair (Milk, Latte). In an undirected graph, each edge simply connects two vertices, with no particular order. For example, in a road system graph there's a road between Los Angeles and San Francisco. The edge (road) between the vertices (cities) Los Angeles and San Francisco can be expressed as either of the following: {Los Angeles, San Francisco} or {San Francisco, Los Angeles}. Acyclic An acyclic graph is a graph with no cyclethat is, no path that starts and ends at the same vertexfor example, employee organizational charts and BOMs. A directed acyclic graph is also known as a DAG. If there are paths that start and end at the same vertexas there usually are in road systemsthe graph is not acyclic. Connected A connected graph is a graph where there's a path between every pair of verticesfor example, employee organizational charts.

A tree is a special case of a grapha connected, acyclic graph. A rooted tree is accessed beginning at the root node. Each node is either a leaf or an internal node. An internal node has one or more child nodes and is called the parent of its child nodes. All children of the same node are siblings. Contrary to the appearance in a physical tree, the root is usually depicted at the top of the structure and the leaves are depicted at the bottom. (See Figure 9-1.)
