1. The document discusses how to connect various GIS software including ESRI ArcGIS, MapGuide, MapServer, and GeoServer to PostGIS spatial databases.
2. Basic steps for connecting MapGuide to PostGIS include downloading the FDO provider, copying files, and creating a provider configuration file.
3. For MapServer, PostGIS support must be compiled in and the CONNECTIONTYPE parameter set to POSTGIS, with CONNECTION used to specify database connection details and DATA to define layers from PostGIS tables.
4. GeoServer supports connecting directly to PostGIS spatial tables.
The document discusses Geo Mush up and Application by Chaipat Nengcomma. It describes Google Maps and Google Earth APIs which allow embedding maps and 3D globes into web applications.

1) AJAX stands for Asynchronous JavaScript and XML. It allows web pages to update parts of a page asynchronously by exchanging data with a web server behind the scenes without reloading the whole page.
2) AJAX is based on open standards like JavaScript, XML, HTML and CSS. It allows for cross-browser and cross-platform applications.
3) The document discusses how AJAX uses the XMLHttpRequest object to send and receive data from a server asynchronously by HTTP requests in the background. This makes web applications more interactive and responsive.
The document discusses the emergence of GeoWeb 2.0, which involves merging geographical location-based information with information on the traditional internet.
