Heavy loaded ecommerce solution

Need your advice

[WebRIPPER]

My client ordered VERY LOADED solution. He has 600k items in more then 20k categories. I checked almost everything and nothing those days can provide such solution in php/mysql.
Your advice... What can you advice me to use as front end software to provide ability to work with such large number of categories?

Look into PostgreSQL, Oracle, or ummmm MS SQL Server. It seems with that many categories, you could break the site up many times and run multiple domains. All the different sites could use the same database.

There's been talk about the frequency and maximum number pages [webmasterworld.com] a site will be crawled for based on your PageRank. Your links should also allow for all products to be crawled -- whether they are static links or search queries that output linkable search results.

That's no DB problem, that's seemed to be non optimized php problem.
It's looks like no shopping carts optimized for large amount of categories/products
I WANT to be wrong...

Take a look at make-a-store . Their highest end product allows you to list unlimited number of products and categories.

Try eCommerce Templates - their UK based, but I've worked with several large carts through them, though not as large as the one your working with.

i like the break up into micro channels idea with multiple domains. Its always better to be an inch wide and a mile deep then the opposite.
