One of the common causes is lack of proper maintenance. Servers need regular updates, both in terms of software and hardware. If they don't get that, they can become vulnerable. Also, overloading the server with too much traffic or too many tasks at once can lead to crashes. It's like asking a person to do ten things at the same time - something is bound to go wrong.
A common horror story is performance issues. For example, a query that was supposed to run in seconds took hours. This was due to bad indexing. Indexes were not created properly or were missing for important columns used in the WHERE clause of the query. Another is security breaches. If a SQL Server has weak authentication or improper user permissions, it can be easily hacked. Hackers can then steal sensitive data like customer information or financial records.
One common cause is lack of proper testing. If you don't test all aspects like functionality, compatibility etc., it can lead to disasters during deployment.
One common cause is human error, like an accidental deletion or incorrect data entry. For example, an employee might accidentally drop a crucial table in the database.
One common cause is physical exertion without enough water intake, like in sports or long hikes.
Poor testing. If software isn't tested thoroughly, it can lead to all kinds of problems like the ones in horror stories. For example, bugs that should have been caught can go unnoticed and cause major issues when the software is in use.
Poor maintenance is a common cause. For example, not cleaning out grease traps regularly. If you don't do this, they will overflow with grease.
Poorly written SQL queries can also lead to horror stories. For example, queries with incorrect joins can result in wrong data being retrieved or updated. If a developer doesn't fully understand how to use JOINs correctly, it can mess up the whole data integrity.
I think human error is a big part of it. Workers might accidentally drop packages or load them onto the wrong trucks. Inadequate quality control in the shipping process is another cause. There should be checks to make sure packages are in good condition before they are sent out. But often, this doesn't happen. Also, theft during shipping, although not very common, can be a cause of horror stories when valuable items disappear.
Data loss is very common. For example, database corruptions can lead to important emails disappearing. Another is security breaches like when hackers get in. Also, misconfigurations during upgrades or installations can cause major disruptions to users' access to their emails.
Well, supplier failure is a big one. This could be due to financial problems at the supplier's end, like bankruptcy. Also, quality control issues are common. If a supplier can't maintain the required quality standards, it can cause a lot of trouble in the supply chain. And political instability in a region can also disrupt supply chains, for example, through new trade regulations or tariffs.
