OpenLayers Database Text
This map has a 'text' layer pointed at '
db2text.php', a script which queries the database example.db and generates text in the format OpenLayers can use to display lots of markers
(
see the generated text)
In this case OpenLayers makes a single request, and db2text.php simply fetches every point from the database,
which takes a little while at the server-side. The amount of data returned can also overload your browser
a bit. These difficulties are takled with the
BBOX strategy example.
