It's not just the online businesses that need a digital storefront, but also the physical space businesses! And believe that it is increasingly important for companies/businesses to have a strong online presence, with particular emphasis on the website (but not only). Because consumers only consider the companies/brands they can find online, so having a website is an obligation of any business/business. But it is not enough to have a website, you must have "The Website", which represents your brand values and ideas, publicize your products/services and contribute to the loyalty of your target audience.
BUT WHAT IS FRONTEND?
Eg.: images, links, buttons, some text, pop-up windows, among others.
AND THE BACKEND?
While the backend refers to the administrative panel of the website, to your back office/server, which allows you to manage the content, add pages, publish articles on the blog, etc. By standard is composed by:
In Double, we use the .NET language with C# and MS SQL Server in the backend, which in turn allows the website to collect information from a server, online data, and files (later presented in the browser).
After all, it becomes easier to see what the differences between the backend and frontend are, don't you think?
