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.

How do you troubleshooting and tune oracle without oracle diagnosics pack and tuning pack?
See "statspack survival guide"
plus you can still generate AWR reports (uder some circumstances). Use google
you can also watch v$ views using own sql scripts.
I used some reporting platforms ( SAP Business Objects and some other third party applications). I have pl-sql experience but I am new to Oracle BI.
At this point, I have some questions which confuses my mind.
First one is there are lots of terminology in Oracle BI but I do not know which products should I know, or in which order I can learn and experience these platforms.
For example you can create dashboards, analysis by Oracle BI. Terms/products like Essbase, Hyperion, Warehouse Builder, ODI etc.
My second question is :
I want to install Oracle 11g and Oracle BI 11 in the same pc. But I hearded and read on some forums that they are not working on the same computer. But I want to setup BI tool to my personal computer for practicing in my home. How can I install these two products in my pc? ( My pc is 64 bit)
Thanks&Regards
Just dot it ;-)

You can have a database and obiee on the same machine.

You need to install Oracle DB 11g followed by the latest OBIEE 11g installation. (note that you need to install RCU before you proceed with the OBIEE 11g install). You can get both of them from otn.oracle.com. The Install documentation can guide you in the entire setup; and hopefully there should be no surprises.
After that, install the Sample App and follow the instructions to create new analysis, dashboards etc. After this, am sure you will be upto speed with the terminologies and the workflows.
Check this post on wiki - should give you basic understanding on OBIEE stack
http://en.wikipedia.org/wiki/Oracle_Business_Intelligence_Suite_Enterprise_Edition
you mentioned Warehouse Builder - Oracle steering away from it, so ODI will be a choice of ETL tool.
You have a long journey ahead of you for OBIEE so, sit back, relax and enjoy the ride. You want to start with the BI Foundation which includes BI Server and Answers, before moving on to products like Essbase, Hyperion, Warehouse Builder, ODI etc.
I would start by
Doing a simple install of OBIEE. I prefer Linux but you can use Windows as well. 8GB would be nice. Each of the following has a graphical install wizard which guides you through the choices.
a. Install the DB
b. Run the RCU
c. Install OBIEE
d. Install BI Admin tool for creating or modifying the repository
Do some tutorials provided by Oracle. I would start with the following and in this order.
a. Creating a Repository Using the Oracle BI 11g Administration Tool - MANDATORY if you are a serious OBIEE professional
b. Creating Analyses and Building Dashboards - For Adhoc Analysis - Important
c. Getting Started with Oracle BI Publisher - OPTIONAL - If you care for published or printed reports or for some quick and dirty reporting, without having to create a model in the repository.
You want to avoid these common mistakes if you are installing on Windows.
You can install Oracle 11g ad Oracle BI in the same machine without any issue.
As far as the second question is concerned, you can create your reports with the knowledge of only Oracle BI , pl/sql and 11g. Pl/Sql is required to writhe pre and post procesors for the report. ESS will only be required to schedule the report and as such you won't require it in the learning phase. You can learn it later
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.
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.
Does LINQPad work with Oracle? Has anyone tried? What do you suggest?
As of beta version 4.35, LINQPad supports Oracle fully - you can now do "LINQ to Oracle" queries. I believe it uses the DevArt dotConnect libraries for managing this great feat. Further, in addition to native OCI support, it also supports a direct mode which does not require the Oracle OCI DLLs to be present.
To enable this feature you will need to simply add a new data connection in LINQPad, and when asked which driver to use - click the View more drivers... button. You can then install the IQ Driver and use it for querying Oracle, MySQL and SQLite databases.
Judging by their user voice item request for Oracle support, it appears unsupported at the moment.
A comment on the O'Reilly forums also suggests its not supported.
update As we understand it, there's now built-in Oracle support in the latest versions of LinqPad; the home page of LinqPad now lists support for Oracle.
update January 2013 The new LinqPad-to-Oracle support appears to still be available. Per the LinqPad FAQ:
Q. Why does LINQPad use LINQ to SQL under the covers, rather than Entity Framework?
A. LINQ to SQL is faster with large schemas and in most cases, emits
better SQL. You can, however, use EF with EDMs that you define
yourself. For querying SQLite, MySQL and Oracle (via the optional
plug-in), LINQPad uses Matt Warren's IQueryable toolkit.
Linqpad now has support for lightspeed which supports oracle.
