With ever the constant updates to popular and important apps and websites, how do the developers ensure the update preserves the user and site's original database, considering the possibility that the updates might contain data-corruptive bugs or exploits for users?

This question is not addressing the frequent database leaks, since they only involve release of read only data and exploits only exist in the form of accessing user accounts and data, not altering the site's database at large itself.

Even if there is a backup for the database, undoing changes that affect millions or people negatively would create a ton of uproar, especially if the site is based on real time interactions, like stock broker apps, social media apps and instant messengers. However I have personally never heard of such incidents.

Do companies at such large scales have extreme QA in place, depend on user feedback and reporting, or just have been lucky they haven't been exploited yet? Or am I completely wrong and these incidents do occur?

Keep in mind that I am an amateur in this domain. I have worked with MySQL databases for educational purposes and personal projects but I found the state of databases very fragile, like the ability to nuke the entire database with just 2-3 words. This fact made me come up with this question.

Specifically you have semi autonomy over every organ in your body, just like how you have with lungs, meaning you can have control over them whenever you like, but the body will continue to function automatically if you forget about them.

You might have observed from previous experiences that many questions in single choice question papers follow some sort of a pattern that unintentionally help make the correct options predictable or at least help with cutting down on the incorrect ones.

Some of the commonly known ones are:

1. Same option number shouldn't be selected for multiple consecutive questions
2. Options like 'All of these' and 'None of these' are mostly incorrect (though 'All of these' is relatively more used)
3. The lengthier and more comprehensive option is usually the correct
4. If all other options are proven incorrect then the leftover one has to be correct
5. If the same option is shared between multiple questions, all of them shouldn't be correct simultaneously

Are there any other patterns you observed?

I am not a professional gamer nor do I have much time to invest into a game in one stretch. However I do enjoy the cumulative progress I make with each session I have with the games, specifically progress of acquiring loot, money, powers or in-game materials. Are there any games that try to match my interests?

An example of such games would be Papa Louie's food games. Though these are very simplistic and made for kids, their per-day game sessions (which last about 10 minutes) perfectly fit the idea of the type of game I am looking for. (I could have come up with a more appropriate or mature example, but that is exactly the point why I am looking for similar games.)

I have looked into the genre of roguelikes, however the basic premise of these games are that they start all over again from each session, which is what I am trying to avoid.

I can play on PC (controller included) and mobile. Apart from this, I would really appreciate if the game is under 10GB, single-player and is just easy in general to understand and play.
