SQL databases and database calls

This is probably the most important area of the majority of 3.0 websites as they are mainly set in wordpress or similar sites. These sites use CSS in order to keep the size of the sites small whilst simultaneously using SQL databases to store all the information which is only called forward when a user goes to look at that page, this saves again greatly on space. However, due to the bandwidth (discussed later) many sites now have a cap on how many SQL calls can be made. An SQL call is simply the site saying to the database I need X information and the data base supplying it. Usually a website will not need to worry about going over this limit, but if you run a popular blog you will quickly find that you may get error messages where calls are unable to be made as your limit has been reached. In order to find out the maximum SQL calls either email support or read the terms and conditions you can usually find the answers there.

Bandwidth, life blood of a website

Earlier you may have seen me mention bandwidth. Bandwidth is the lifeblood of a website as it is identifies the limitation of data transfer your website can take before being taken offline by the providers. As earlier mentioned having files to download directly off your hosting provider does use up a lot of space but it also uses up a lot of bandwidth. Usually a visitor will only need to upload the basic information in order to view a webpage which is usually less than a megabyte without including pictures. However when you add in things to download bandwidth can quickly be exceeded, so try your best to not allow large downloads directly and to use a third party server.
