Program for automatic information acquisition, - or, in programmists language, parser, - is a perfect solution for distribution companies.
For example, you are a distributor some product with very changable or very long price-list (say, clothes, or ball bearings).
So, you have two ways of filling the catalogue on your site.
First is: you ask your supplier for illustrated price-list, you copy all information manually, and every time your supplier changes something (adds new product or removes old one) - you need to make manual correction.
For sure, it is very hard not to make a mistake doing this job.
And there is another way - you can take the information right from your supplier's web-site (for sure, if he is not against this idea).
How? Very simple.
All you need is to contact u, sign a contract, name the site you want to take information from, and - here we go!
Every time the producer changes something, you just star the parser once again - and it adds or removes product according to fresh data. Isn't it nice, really?
because we know how to do it…gently.
