hi everybody
plz i need to ask a question about WebMapping applications
am very new to web-mapping, so this question may be a little misguided.

I want to develop a simple web mapping application using OpenLayers which can display Cadastral information that are currently in PostGIS(2 tables: property and bornes).

I want this to be as simple (and as low maintainence) as possible:

and then the user can generate the an A4 sheet for print that contains the title/property plan and also a table containing the name, X and Y of boundaries of title/property
