A relational database system contains one or more objects called tables.
The data or information for the database are stored in these tables.
You will often hear the term Best Practices used in Application Architecture.
The danger of such a term is that it gives one a sense that there is no need to question a practice because it is always best.
Often you will find that even in a single application a mixture of approaches works best.
Before dismissing one approach over another, it is important to map out what you are trying to achieve and then determine how using one approach aligns with your objectives.

Do not confuse this with PHP's My SQLi connector, which is part of PHP. Before anyone flags this as already asked, I've looked through a bunch of similar questions and tried various answers and it none of them are working. I am trying to create a array of temperture readings within a time range, but limit it to only 1 reading for every 10 readings.
value that was inserted by a client in a different time zone, you will get a value that is not the same as the value stored in the database.
As long as you don’t change the time zone, you can get the same column can be automatically initialized to the current timestamp for inserted rows that specify no value for the column.
The fields in a view are fields from one or more real tables in the database.
You can add SQL functions, WHERE, and JOIN statements to a view and present the data as if the data were coming from one single table.
(Because the procedure for installing My SQL is different on each platform, and because the installation process is nearly automatic in modern times, I've decided not to cover installation issues.
