BCS-062 : E-Commerce Q1. How E-Commerce Portals maintain the state of Shopping Cart in case of any interruption during online shopping by the Customer? Ans: Keep your Ecommerce Shopping Cart Software Updated This is one of the most important steps when it comes to maintaining your own e-commerce website. You need to be sure to keep your shopping cart software updated to the latest version. In some cases you can easily run an update within the shopping carts web portal; but in other cases, you will have to hire help for this task, as the software will require you to download the new version. Go into the backend of the file manager, and upload the files manually to either the file system or the database. Delete Old Files You will need to make sure you do not keep old, unwanted files within your hosting account?unless they are very small. Many times large images or videos that are not used will take up a lot of space. This does not make a difference in a Cloud, VPS or Dedicated Hosting environment, but it can make a difference in shared hosting space. Back Up Your Complete Website It?s very important as the owner of your website that you have a copy of the site accessible to you at all times; this makes it easy for you to make changes and upload your site to the server. Additionally, if you break something on your website, you can easily upload it via your own local copy. As a web host, we keep 2 copies of backups for all of our customers, but we always encourage customers to have their own local backups, just in case. Make Sure to Compress Large Images One of the most important rules when it comes to having your product pages load fast is to make sure you do not upload product images that are too large. Oversized product images or thumbnails will cause your web page to download more slowly. Users do not want to wait to purchase products: they want the process to be fast, and they want all pages to load quickly.
