   • MySQL multiple databases and users

     Top Answer

     Answered Aug 29, 2015 · 0 votes

     First off, you want to define more of a role that the databases are going to serve.

     It really depends on the magnitude of the information expected to be held if you should have one database per company or one master database.

     Note that most web hosts would not allow you to host 1000+ databases unless you are running your own dedicated database server. Cost definitely becomes a factor there.

     For Employees, Projects, and Messages, one database should be sufficient.

     Using the web interface, you only need the single database-user for the website itself to connect to the database. It is then up to how your website handles the website-user logins and what data each user has access to.

     So for this you need to create a website-user-table in the database that handles the user login information, timeouts, intruder detection, and what information in the database that user has access to.

     For each table of information, for example, you can have a single column with a unique company ID. Your website then allows a user that belongs to that company to see the information for that company and no other.

     So your tables for the database will probably be:

     --------- Web_Users Company Employees Projects Messages ---------

     With the Web_users, Employees, Projects, and Messages tables linking to Company table using a foreign key.

     This setup keeps your database secure because only your website can access it, and only those who can log into your website can then access information--only the information that belongs to the company that the user belongs to.

     This puts the majority of the security burden on how well you write the website interface.

     Hope this helps!

   • Mysql Sub Databases?? What are they called

     Top Answer

     Answered Apr 12, 2012 · 5 votes

     I don't think there is a name for these -> you get them in PHPMyAdmin if you name something with an underscore (like "maindb" and "maindb_test" ), but for MySQL itself there is no difference. It's just how PHPMyAdmin tries to make it more clear.

     You have no other databases - try to create one.

     The current user is probably the anonymous user - by default MySQL ships with the following users, all having empty password (https://dev.mysql.com/doc/refman/5.5/en/default-privileges.html)

   • MySQL vs File Databases

     Top Answer

     Answered Jan 31, 2009 · 1 votes

     I would choose a MySQL database - simply because it's easier to manage.

     JSON is not really a format for storage, it's for sending data to JavaScripts. If you want to store data in files look into XML or Serialized PHP (which I suspect is what you are after, rather than JSON).

     For a small, single user 'database', a file system would likely be quicker - as the size and complexity grows, a database server like MySQL or SQL Server is hard to beat.

     I would definately choose a DB option (as you need to be able to search and index stuff). But that does not mean you need a fully realized separate DB service.

     MySQL is definitely the more scalable solution. But the downside is you need to set up and maintain a separate service.

     On the other hand there are DBs that are file based and still give you access with standard SQL (SQLite SQLite.org) jumps to mind. You get the advantages of SQL but you do not need to maintain a separate service. The disadvantage is that they are not as scalable.
