Does anyone know a good opensource tool that can be used to manage Entities in Oracle 11G? For Mysql we have workbench even-though it has some bugs it's getting better. As for Oracle I couldn't find a tool for modeling data. I hope someone could lead me in the right direction. Thank you.
Oracle's Data Modeler is not open source, but it's free:

How to convert an Oracle DB 11.2.0.3 to a 12cR2 PDB using Oracle Sqldeveloper?
As far as I can tell, you can't do that. SQL Developer does quite a lot of things, but I doubt that it is capable of upgrading a database version.
This is the Database Upgrade Guide (https://docs.oracle.com/database/121/UPGRD/toc.htm). Recommended method is Database Upgrade Assistant (DBUA), although you can do it manually. The question is: are you capable of doing it? I'm not implying that you're stupid, God forbid, but you might not have enough knowledge and/or experience. Perhaps you should discuss it with a proper DBA.
Im new to oracle multidimensional models...
I have followed the "Creating a Multidimensional Model" 15 min Oracle tutorial. Tutorial Link
Note: This tutorial use sql developer data modeler.
I would like to know how to query the created data cube using SQL Developer (I.E. using regular SQL DML statements). Every time I look for information online I end up getting links on how to use the Oracle Analytic Workspace Manager. Why? I would like to just build the cube and query it without having to make use of the Oracle Analytic Workspace Manager.
I would appreciate if somone could let me know if I am missing some steps. (a short simple example would be nice)
Thanks in advance.
I realize you asked this in August 2013, but in case it still helps you or others, as of Feb 2014, SQL Developer has an OLAP extension which seems to be what you were looking for...
http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/sqldev-releasenotes-v4-1925251.html
The OLAP extension enables you to use the familiar environment of SQL
Developer to create and manage dimensional objects in Oracle Database
12c Release 1 (12.1.0.1.0) or higher. Oracle OLAP provides advanced
multidimensional analytic capabilities and storage within the
database, including excellent query performance, fast incremental data
updates, efficient management of summary data, and rich analytic
content, such as time series calculations and both additive and
nonadditive aggregations.
I have created a database in oracle 11g. and now i want to see table relationship diagrams like we can see in mssql server 2005.
Can anyone suggest ?
Oracle is still catching up on the need to make things easier for developers. However, they took one step in the right direction in 2010, by making SQL Developer Data Modeler free to use. This product includes a reverse engineering capability, which allows us to generate table relationship diagrams. Find out more.
What options do I have to connect from VS 2010 to other databases like Oracle etc.? What's the best solution?
Now I'm using entity framework (for MSSql DB) and would like to know if it's posssible to use it also for Oracle? I think there are some third party solutions but want to avoid them because of the costs.
Thanks in advance.
Regards.
There is this possibility

then there is nhibernate
And also this other one

You could just install the Oracle Data Access Components (ODAC) that automatically integrate with Visual Studio. Other databases would likely have something similar.
Can you please give some tips or guidelines, best practices for MicroSoft SQL server to Oracle Data Migration? IMHO, it is something that comes best with experience. So I would like to benefit from your experience. Please share any insights that you have into design, modeling, testing or tuning for a data migration project. I would really appreciate if you share your experience even if it is not between these two RDBMSs.
Oracle offers a free IDE, SQL Developer, which includes a Migration Workbench to support moving data from MS SQL to Oracle. Check it out.
