We have a windows server, where while installing Oracle, one database has been specified and created. I want to create an application in ORACLE on the same server, but I want to create and use a different database for this application. My mentor says that the server can hold only one ORACLE database and my request can not be implemented. Is there a way out of this ?

I would like to develop a ER diagram using DBeaver (Eclipse plugin) for a database that doesn't yet exist. Also, the database server doesn't exist.
Can DBeaver be used to develop a ER diagram without connecting to an existing database server? I can only find documentation for working with an existing database or connecting to an existing database server.
Nope, sorry.
DBeaver tools are always associated with the current connection.
For example, in the ERD when adding tables, DBeaver often sends requests to the database of foreign keys.
You can use standard sample SQLite database in DBeaver for experiments.
DreamFactory installer (via php artisan) is prompting "Enter your database name:", not sure what database means, it wants me to set a brand new database name or a name for existing one?
You need to provide a database for DreamFactory to use to store its configuration options and users. This can be sqlite, mysql, postgres, or sql server (paid option.)
When you run the setup command you need to provide the database connection information for an existing database. If you don't have a database, you can choose the sqlite option instead of one of the others. sqlite is file based and requires no server infrastructure. The database will be created for you automatically in that case.
I know that SQL Server has linked server that allow it to connect to other database and execute query. Now I am using firebird. I wonder if firebird has its "linked server" to access other databases. Thanks!
Firebird doesn't have a linked server feature. There is a limited method for accessing other Firebird databases (either remote or locally) using EXECUTE STATEMENT, however this only supports Firebird database, and you need to provide the data source information on each invocation.
1 and i'm connected to intern database java:jboss/datasources/ExampleDS
i want to browse the data like sql in tables etc. in the administration console of jboss
but there is no such option in Administration menu or can someone help me on how to browse data? Or is there some other tool on this?
Database has nothing to do with application server. First you have to find out what database server is datastore ExampleDS using. Then connect to that server. Example: if ExampleDS uses Mysql on 192.168.1.1:3306 you have to use some Mysql client (Mysql workbanch) to connect to that server. There you can see actual tables.
Suppose I have multiple Oracle databases in the same server. Now I want to connect to particular database and query a table just like SQL Server 2008. How to start particular Oracle database?
If you are using SQL*Plus, the most common syntax for opening a connection is
sqlplus user_name/password#tns_alias
In this example TNS_ALIAS is the TNS alias for the particular database you want to connect to (most likely "XE" based on your followups to inium's answer). If you want to connect to a different database, you would need to specify a TNS alias for that specific database.
Note that since you are coming from a SQL Server background, the SQL Server definition of a database is rather different than the Oracle definition. What SQL Server calls a database is similar logically to what Oracle calls a schema (and similar physically to what Oracle calls a tablespace). So when you're dealing with Oracle, it's much more common to have many schemas in a single database than to have a large number of databases on a server. This is particularly true if you're using the Express Edition (Oracle XE) where you're generally limited to one database per machine.
go to cmd and type sqlplus <database-name>/<database-password>
You can use SQL Developer, it's similar to SQL Enterprise Manager 2005. Just create a new connection using the db user name and password.
