Apparently the Community brings everything, things that surely I will never use. I just want to be able to create and work with database and Eclipse.
What should I install to create a database and achieve the connection with Eclipse ?. Only the Workbench or should it be the complete Community ?. The Notifier is required?.
To work with databases, in this case MySQL, you will need a MySQL server. A MySQL server is nothing more than a program that responds again and again to all your SQL requests (Your SQL code). And on the other hand you will need a client to be able to see your tables, etc ... I personally recommend that you use XAMPP or MAMP or some program of the style although I recommend one of those two. These programs not only bring you a MySQL server but also bring you Apache server (web) and what a client named MySQLAdmin could really come up with, among other things. As you may have read, MySQL Workbench is just a client and Community is a server (I do not know if it brings a client) so you would have a bit of bad luck to use the 2 (if you do not bring a client) something with XAMPP or MAMP would not happen from the beginning.

Wokbench is a tool that allows you to interact with MySql databases, Mysql Community is the database server that you install which you can access from Workbench, according to this reasoning, you could dispense from Workbench if you want, but not from MySql server.
The MySQL Workbench offers two versions, the Enterprise and the Community. I work with MySQL database and I use the Community version. With it you can design the database, create relationships, update tables, etc. If in case the connection fails for some reason you can export the code and execute it in console. It is a recommended tool.
