How to create a Chevereto user or other operations in the database?

[1200]

I want to reconstruct the Chevereto image program, but I don't want to completely discard the old Chevereto data, How do I write some of the data from the old Chevereto image site in a newly created Chevereto site database?

For example, I just want to write a piece of user data on the old Chevereto image website database into the newly created Chevereto image website database.
For example, I also want to restore the index link data of a picture on the old Chevereto image website.

How should the above mentioned be implemented?

In addition, such as the number of image views, popular, recent, moving pictures and other data recovery and so on.

Finally, I also want to know what kind of function each data table in the chevereto database has played?

What you are asking is not that trivial as you may think. The data is in a relational database, which means that the data relates to something meaning that you can't expect to simply inject database records neither import old records if you don't keep the data relations.

For example, the chv_logins table is related to the chv_users table, same as chv_images, chv_albums, etc. Long as you keep the data relations in place, the system should work as expected.

All the content related classes (class.image.php, class.album.php, etc) include wrappers to interact with the database for all CRUD operations, so in the case you really want to inject something I suggest you to use these wrappers.

Keep in mind that the system wasn't designed for the kind of data merging that you want to achieve, I can't give you any instructions on how to achieve exactly what you need because there's no procedure for such thing.

Does that mean re-creating a Chevereto website means that everything starts again?

I said that the database has relationships that you must either update, generate, remove, etc. in order to achieve what you need. How you modify these relations depends entirely on the data-set you have and what you want to get from it.

I suggest you to examine the SQL table structure present in app/install/sql/ to get a better idea.
