What is the olap in bw ?

hi experts,
    today i received an architect document which discribe the architect of the DW system .
   the architect shows below:
some data sources -
> ETL -
>DW (SAP BW )   -
> ETL -
>OLAP -
>some report display tools
    what makes me confussed is what the OLAP component is ? now i have create some cubes and what should i do to implements the OLAP component ?
    i think the olap is just the drill down , filter function. can someone tell me what the olap is ? your help is appreciated and assign points if it helps!

Hi,
SAP Business Information Warehouse uses OLAP technology for the analysis of data held in the data warehouse. Online Analytical Processing (OLAP) characterizes BW as a Decision Support System. OLAP allows decision-makers to quickly and interactively analyze the multi-dimensionally modeled data appropriate to business Considerations.
InfoProviders allow this data to be viewed. As data is stored in InfoCubes optimized for the reading of data, InfoCubes and MultiProviders for InfoCubes should be the preferred InfoProvider.
Check out this link for "OLAP Functions and Services "

What are the OLAP cube data access auditing capabilities

Hi All,
We are currently activating RDBMS fine-grained-audit (FGA) policies on our datawarehouse to comply with security policies in place in our company.
Part of our datawarehouse store financial confidential data for which we need to perform access auditing.
The confidentail data reside in fact tables that are also used to feed OLAP cubes.
Are there FGA capabilities (or similar) available to audit access to confidential data stored in OLAP cubes ?
Thank you.

What's the Difference Between OLAP and OLTP?

HI,
What's the difference between OLAP and OLTP ? and which one is Best?
-Arun.M.D

Hi,
The big difference when designing for OLAP versus OLTP is rooted in the basics of how the tables are going to be used. I'll discuss OLTP versus OLAP in context to the design of dimensional data warehouses. However, keep in mind there are more architectural components that make up a mature, best practices data warehouse than just the dimensional data warehouse.
Corporate Information Factory, 2nd Edition by W. H. Inmon, Claudia Imhoff, Ryan Sousa
Building the Data Warehouse, 2nd Edition by W. H. Inmon
With OLTP, the tables are designed to facilitate fast inserting, updating and deleting rows of information with each logical unit of work. The database design is highly normalized. Usually and at least to 3NF. Each logical unit of work in an online application will have a relatively small scope with regard to the number of tables that are referenced and/or updated. Also the online application itself handles the majority of the work for joining data to facilitate the screen functions. This means the user doesn't have to worry about traversing across large data relationship paths. A heavy dose of lookup/reference tables and much focus on referential integrity between foreign keys. The physical design of the database needs to take into considerations the need for inserting rows when deciding on physical space settings. A good book for getting a solid base understanding of modeling for OLTP is The Data Modeling Handbook: A Best-Practice Approach to Building Quality Data Models by Michael C. Reingruber, William W. Gregory.
Example: Let's say we have a purchase oder management system. We need to be able to take orders for our customers, and we need to be able to sell many items on each order. We need to capture the store that sold the item, the customer that bought the item (and where we need to ship things and where to bill) and we need to make sure that we pull from the valid store_items to get the correct item number, description and price. Our OLTP data model will contain a CUSTOMER_MASTER, A CUSTOMER_ADDRESS_MASTER, A STORE_MASTER, AN ITEM_MASTER, AN ITEM_PRICE_MASTER, A PURCHASE_ORDER_MASTER AND A PURCHASE_ORDER_LINE_ITEM table. Then we might have a series of M:M relationships for example. An ITEM might have a different price for specific time periods for specific stores.
With OLAP, the tables are designed to facilitate easy access to information. Today's OLAP tools make the job of developing a query very easy. However, you still want to minimize the extensiveness of the relational model in an OLAP application. Users don't have the wills and means to learn how to work through a complex maze of table relationships. So you'll design your tables with a high degree of denormalization. The most prevalent design scheme for OLAP is the Star-Schema, popularized by Ralph Kimball. The star schema has a FACT table that contains the elements of data that are used arithmatically (counting, summing, averaging, etc.) The FACT Table is surrounded by lookup tables called Dimensions. Each Dimension table provides a reference to those things that you want to analyze by. A good book to understand how to design OLAP solutions is The Data Warehouse Toolkit: Practical Techniques for Building Dimensional Data Warehouses by Ralph Kimball.
Example: let's say we want to see some key measures about purchases. We want to know how many items and the sales amount that are purchased by what kind of customer across which stores. The FACT table will contain a column for Qty-purchased and Purchase Amount. The DIMENSION tables will include the ITEM_DESC (contains the item_id & Description), the CUSTOMER_TYPE, the STORE (Store_id & store name), and TIME (contains calendar information such as the date, the month_end_date, quarter_end_date, day_of_week, etc).

How do I know what is the minimum resource requirement for OLAP 11g?

How do I know for OLAP 11gR1 ...
1. what is the minimum number of CPUs and speed required
2. how much minimum physical memory, SGA, PGA etc. is required?
Regards, Anirban

Hello Anirban,
In summary, since the OLAP option is an option to Oracle Database 11g, Enterprise Edition the minimum requirements in order to run the database would be identical to those necessary to run a "Data Warehousing" type installation. That being said starting up a database is a far cry from actually performing well while accessing and building OLAP Cubes in your Database.
There are lots of things to consider. For example: the complexity of your model; data sparcity; level of aggregation; system load, SLAs, etc..
Lets look at true minimum requirements and then consider what it would take to achieve good performance in your environment
TRUE MINIMUM...
I performed a test in my environment (Oracle Database 11g Release 2 (11.2.0.2.0) on Oracle Enterprise Linux 5.5) using Analytic Workspace Manager 11.2.0.2.0A and found the following minimum settings to work against the OLAPTRAIN schema (You may find it here http://www.oracle.com/technetwork/database/options/olap/index.html). This is a very small schema which we use for demonstration purposes.
I discovered that the database started with a memory_target of only 160m (apparently this is the absolute minimum for my environment). I knew that if the database successfully started that I would be able to query the Cube but maintain it? Running queries against the OLAPTRAIN Sales Cube, despite being slow, worked as anticipated. Next, I performed a maintain operation on the Sales Cube where I had to abort the job because it ran into memory issues at 160m, however, when I increased it to only 180m it did a complete maintain in a reasonable timeframe, albeit slow considering the limited resources.
MINIMUM REQUIREMENTS TO ENSURE REASONABLE PERFORMANCE IN YOUR ENVIRONMENT
Most importantly ensure you have a good cube design
Run a sample set of your data in order to define what "reasonable performance" is for your environment. Create a small representative cube in order to test both build and query performance while collecting and analyzing database statistics through AWR and ADDM. For OLAP option specific queries please take a look at http://wiki.oracle.com/page/OLAP+option+-DBASample+Scripts.
You could creat a view on top of your fact table and use the view to generate your OLAP Cube. This will allow you to test a more manageable amount of data. For example, if you have 10 years of data and want to determine the footprint and resources required in order to manage a Cube of this volume then consider scoping it down to a few months first then increase it by a measured amount in order to predict requirements. Monitor your resources and ensure you balance I/O, memory and processors. Since the OLAP option is a Enterprise Edition option it falls under Data Warehousing. As such there is plenty of literature available on oracle.com in order to define what it takes to achieve a balanced Data Warehouse.
I would recommend contacting Oracle Consulting or an Oracle Partner to determine the best fit for your environment.

What is the proper role of OLAP meta-data?

One basic feature continues to confuse me with regards to the Oracle OLAP option. What is the proper role and/or purpose of creating OLAP meta-data? Since you can now use the Analytic Workspace Manager to create multi-dimensional OLAP objects, doesn't that now create all the neccesary meta-data in the Analytic Workspace itself?
We have created a fully functioning prototype system with both multi-dimensional cubes as well as relational tables using both Oracle Discoverer for OLAP and Oracle BI Discoverer to view that data. And we have done so without EVER taking the explicit steps to create OLAP meta-data, i.e. using the CWM or CWM2 packages. Am I missing something? Is it still neccesary to use these packages and if so what are they for? Are there any Oracle OLAP experts that would care to comment?

Most implementations of the OLAP option are analytic workspaces (MOLAP). The usual motivators towards MOLAP are performance of builds/aggregations and query and additional calculation capabilities offered by the multidimensional engine. Also, the administrative infrastructure is better with MOLAP (because that's what most users use).
Sometimes customers want to do a ROLAP implementation because they're more familiar with tables and feel comfortable about managing security, high availability and disaster recovering. Also, some customer want to access the data with SQL based tools. But, remember with Oracle OLAP the data is all in the database (safe, secure, same management practices, RAC/Grid enabled, etc) and you can query it with SQL. Those are some of the things that make Oracle OLAP so terrific as compared to stand alone OLAP servers.
That doesn't necessarily mean that MOLAP is correct for every application, but MOLAP is probably used more than 90% of the time.
If you would like a white paper discussing when to use MOLAP, feel free to send me at email <[email protected]>

What is the transaction to enable the olap cache in the report

Hi all,
please let me know what is the procedure to improve the performance of a query?
how can i tune a report?what are the steps i need to take to improve the performance in the report?
please mention all the transatction codes whare i have to check and what i need to do to achieve the good perfomance?
thanks in advace,
ashok.

Primary Tcode is RSRT.
Go mto RSRT and give your query name and select exceute _ debug.
Then you will get a lots of options to run the report.
Caching will set uo thru SPRO. Work with your Basis for this.

Refresh of Webi in BI Launch Pad : "Failed to connect to the olap source"

Dear all,
I have a Web Intelligence document based on a BEx Query (BICS connectivity via an OLAP Connection configured with SSO)
Behaviour :
in Web Intelligence Rich Client (2 tier and 3 tier) : refresh is OK
in BI Launch Pad : refresh is not OK :
What can be the reason ? In my opinion SSO to BW is working fine because :
refresh in Web Intelligence Rich Client is OK
refresh of an Analysis Application (Design Studio) based on the same OLAP connection is working fine in Design Studio and in BI Launch Pad

WHAT IS THE USE OF 'ALTER DATABASE CLOSE' ?
I need explanation. Why should i shutdown?
Dont give me this answer.
ORA-16196: database has been previously opened and closed
Cause: The instance has already opened and closed the database, which is allowed only once in its lifetime.
Action: Shut down the instance.

If you read the documentation you will see that there is no ALTER DATABASE CLOSE command.
This is an undocumented Oracle command, which we are not supposed to use. Consequently we are not allowed to complain about the way that it works. Instead we're supposed to use SHUTDOWN IMMEDIATE.

What are the best options to replace the SSRS parameter panel?

Hello.
One of the biggest weakness of Reporting Services is definitely the fact that we can't design ourselves panel parameter.
Indeed, This one is totally generated by SSRS and cannot be changed. Moreover its design and features are very limited. This weakness is a regular problem for me in my work, when I integrate reports into a web site, for example.
So, we are using some workarounds, such as using the ReportViewer object and fully develop report parameters ourselves in our website. But this is problematic because it must be repeated for each report, this is time consuming and the code behind must query
the OLAP Cube directly to fill the parameters values.
I have seen other solutions like to rewrite the CSS ReportViewer. But again, this is problematic because this change will apply to all the reports deployed on the server.
So, what solution you use? Have you found a magic answer? Or you let the default design?

hello,
Base on my experience,you may only use azure VM to host your project in your scenarios . Because your website and rest service used different program language.
In your scenarios , you could create Sql Azure database to store data and create VM to host web service and website.About how to host website on azure VM, I suggest you could refer to same thread (http://stackoverflow.com/questions/20034341/hosting-an-mvc-web-application-in-a-windows-azure-virtual-machine

What is the best practice for inserting (unique) rows into a table containing key columns constraint where source may contain duplicate (already existing) rows?

My final data table contains a two key columns unique key constraint. I insert data into this table from a daily capture table (which also contains the two columns that make up the key in the final data table but are not constrained
(not unique) in the daily capture table). I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). Currently, what I do is to select * into a #temp table from the join
of daily capture and final data tables on these two key columns. Then I delete the rows in the daily capture table which match the #temp table. Then I insert the remaining rows from daily capture into the final data table.
Would it be possible to simplify this process by using an Instead Of trigger in the final table and just insert directly from the daily capture table? How would this look?
What is the best practice for inserting unique (new) rows and ignoring duplicate rows (rows that already exist in both the daily capture and final data tables) in my particular operation?

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
>> My final data table contains a two key columns unique key constraint. [unh? one two-column key or two one column keys? Sure wish you posted DDL] I insert data into this table from a daily capture table (which also contains the two columns that make
up the key in the final data table but are not constrained (not unique) in the daily capture table). <<
Then the "capture table" is not a table at all! Remember the fist day of your RDBMS class? A table has to have a key. You need to fix this error. What ETL tool do you use?
>> I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). <<
MERGE statement; Google it. And do not use temp tables.

What is the maximum number of characters in an Oracle 10G Instance Name

All,
Can I know what is the maximum number of characters in an oracle 10g instance name under AIX? Is it 7 characters or 8 characters?
regards
Santhosh

One should really make the difference between db_name and instance_name: if instance_name default value is db_name it can be different
(even on a non RAC database).
For example with Oracle 10.2.0.4 you can create a database named DB78 with instance_name=DB12345678:
$ uname -a
Linux lx01.localdomain 2.6.18-92.el5 #1 SMP Fri May 23 22:17:30 EDT 2008 i686 i686 i386 GNU/Linux
$ ps -fu oracle | grep smon
oracle    6353     1 0 20:30 ?        00:00:01 ora_smon_DB12345678
oracle    6412 5596 0 20:37 pts/1    00:00:00 grep smon
$ export ORACLE_SID=DB12345678

How to write ABAP code behind, the OLAP navigation functions

Hi SDN Community,
We have created an artificial hierarchy within BEx, using order structure elements, or characteristic key figures as SAP calls them.
Now, the only feature that dosent seem to be present within the OLAP, is to expand all hiearchy nodes.
It allows you to expand one hierarchy node, but not all the structure element nodes.
I have tried command sequencing by specifying the technical id's of the the structure elements found via RSRT2, but this dosen't work.
I have seen that when the nodes are expanded, that there is indeed standard SAP ABAP code executing back in the datawarehouse.
Hence, do you know
- Where to make ABAP enhancements for OLAP functionality
- How to execute this ABAP (will it be by using Web API and javascript enhancements)
- Is this possible, or has it been done by anyone?
Thank you.
Simon

Hi Thomas,
I have been working with a brilliant ABAP'er, and together we
implemented a solution in the START method, that makes use of the
following methods and expands all the hierarchy nodes at start.
And this class can be omitted in the Print all view we have formulated
as only a collapsed view has been specified there.
thank you.
Simon
I found this all in that class interface CL_RSR_REQUEST
for N_R_REQUEST
for N_R_DATA_SET
Initial Value: Set Drilldown State of a Hierarchy
Description: 'SET_DRILL_STATE'
this looks like the method that gets executed. what do you think?
can you code this in the program
constants C_CMD_SET_DRILL_STATE type RSRCMDID
value 'SET_DRILL_STATE'. "#EC NOTEXT
methods SET_DRILL_STATE
