help designing my classes

[Guest]

hey all,
i have a very simple asp.net application and i'm trying to decide where my
methods should reside in an n-tier context.

i have 2 classes:
BusinessLayer.cs
DataAccess.cs

all the application does is it goes to a database to populate my datatable
and then i dynamically populate an html table from that.

so far, i pass the html table to the businesslayer class which then gets
dynamically populated by a data table. the data table was populated thru the
dataaccess class. all the methods are static.

i could not decide whether the methods that dynamically populate the html
table should go in the ui layer, business layer, or data layer?

would this design also be automatically suitable for remoting?

general suggestions are also welcomed.

thanks,
rodchar

Since the purpose of HTML is to describe how data should be presented then
HTML belongs in the UI layer. Your business object shouldn't have any clue
about HTML.

would this design also be automatically suitable for remoting?

general suggestions are also welcomed.

Another option is to take XML from the Business layer (this could be the XML
that underpins a strongly typed dataset) into the UI layer which uses XSL to
transform to html.
