Wordpress, like any other platform, has a security issue, but for whoever is afraid, buy a trusted server and a trusted theme.
No one is going to attack you on Glide because they can’t even find you, and if you work and earn money first and foremost, it is your interest to be visible online for someone to see you on the search engine.
For a simple thing like Glide you don’t need a plugin or any special server, it won’t be interesting for anyone to attack you. If you are doing a good job then get better and secure yourself, as in real life, you will not put a paper door at the bank entrance!
Database (SQL) and traffic depend on your server vendor. If you are a beginner then you do not bother with this, you do not even need server knowledge and SQL to try and create a school calendar like in Glide.
If you have 1000+ users, lots of sites, options and settings, a web store and thousands of items, then you will either learn to work with databases or hire someone experienced to do the work. Because you can’t do it with Glide anyway, so there’s nothing to worry about.
Wordpress and similar platforms use well-known databases, not google sheet, and if you think that someone can enter your database then they can also get your google sheet.
do you think google sheet is protected? Is your gmail safe? Think twice!
There is a lot of database on my page, for example:
Users fill out the form and independently add their offer to the site, so they log in via email or social networks, enter the name and activity of their offer, address and location so that customers can find you and google maps can display and bring them to you, They upload their photos (up to 128Mb +), cover photo, profile photo, add their phone number for direct contact, sms for direct message, chat for contact via platform, email for contact directly, html or iframe on their booking calendar on AirBnb , Booking-com, Viator, Tripadvisor (connects the user and the owner directly, in real time), Video presentations, youtube linking, all social networks, status view, opening hours (which also displays depending on the time, if you work until 11pm afterwards, the system shows you closed until reopened), offline booking, bookmarking, sharing (link or QR code like on Glide), logging in if incorrect, writing reviews, star rating, commenting and posting photos in reviews , and much more!
The owner has an insight into his offers, promotions of the same through all channels, sees the number of times each ad is viewed, sees the number of views per IP address, per device platform (phone, tablet, desktop, windows version, Chrome browser, Mozilla, OSX, and all with what users are joining, and even Blackberry, if any), they can see what time and what offer their customers are looking at most, when their promotions expire, when they need to renew their offer, can change, edit, add, delete, and more on its own!
Administrators only approve posts after reviewing that everything is filled in, after verification, the ad goes online, renders to all search engines, is indexed, becomes visible, publicly available, and anyone can find it (without someone sharing their link and asking others to look at him)
Isn’t that enough ??? Make it with Glide and let me know!
