发布时间 :2025-10-25 12:24:25 UTC      

This case study demonstrates how to build a complete < AppML > Internet application with the ability to enumerate, edit, and search for information against several tables in the database.

4.6.1. What will we create?

We will use the existing database, named Demo.

For each table in the database, we will:

  • Create a prototype model

  • Create a prototype HTML page

  • Create an application model

  • Create a HTML template

  • Create a complete application

4.6.2. Demo database

For the case study, we used a subset of the Northwind database pre-installed with MS Office.

This database is well known and is easy to test, whether using PHP or classic ASP or ASP.NET.

The Demo database contains several tables with data, as follows:

Principles, Technologies, and Methods of Geographic Information Systems  102

In recent years, Geographic Information Systems (GIS) have undergone rapid development in both theoretical and practical dimensions. GIS has been widely applied for modeling and decision-making support across various fields such as urban management, regional planning, and environmental remediation, establishing geographic information as a vital component of the information era. The introduction of the “Digital Earth” concept has further accelerated the advancement of GIS, which serves as its technical foundation. Concurrently, scholars have been dedicated to theoretical research in areas like spatial cognition, spatial data uncertainty, and the formalization of spatial relationships. This reflects the dual nature of GIS as both an applied technology and an academic discipline, with the two aspects forming a mutually reinforcing cycle of progress.
