myDBR was designed to be a reporting system that can be used without any modifications to the actual user databases. By default myDBR installs into it's own reporting database ('mydbr' by default). All myDBR database objects (including reports) are stored in this database. myDBR only needs read access to the database where the actual data is held.
You can also install myDBR directly to the user database, where your data is (instead of the default mydbr). myDBR uses its own naming scheme, so it will not conflict your data. (myDBR objects have a prefix of: "mydbr_" for tables, "sp_MyDBR_" for myDBR internal procedures, "sp_DBR" for report procedures).
In the login process myDBR checks if the user has credentials to log in to the system. By default myDBR uses it's internal structure to hold usernames/passwords. Following authentication modules are available in myDBR preferences:
If you want to allow the use of myDBR without any login process (public intranet, extranet), you can set automatic login credentials
in Admin preferences. When automatic logins are set, admin access can be gained by pointing the browser to
login.php instead of the usual
Once the login process has been completed, all the operations in the database are done using the username/password stored in the admin preferences
(section Database connection info: Username/Password). These are stored in the
config.php (entries admin_username and admin_password).
These are referred here as 'myDBR credentials'. myDBR credentials must have full access to the mydbr-database and read access to the user
The reports are created in the mydbr-database as stored procedures. myDBR credentials must have execution access to these stored procedures.
When accessing the data in the actual user database one refers to tables using format
'mydatabase.mytable' in MySQL
'mydatabase..mytable' in MS SQL Server, Sybase ASE.
SQL Anywhere does not support multiple databases so reports are created in same database. As an alternative, you can install myDBR in a separate database and use SQL Anywhere proxy tables to link your data tables.
