How to join three dimension tables

I have one seperate schema, which consists of only 3 tables(all three tables has dimension fields and fact fields(dim fields =textual fields,fact fields=measures))
How to handle this type of situation in RPD.
Ex: table A,Table b,Table c
Table A needs to join with Table b on many to one relationship.
Table c needs to join with table b on many to one relationship.
Anyone suggest me what is the best way to handle this type of situation.do I require to create dimensional hierarchies for all three tables? Or can I consider only table b as dimension and remaining 2 consider as fact?

This will not be possible. As per dimensional modelling atleast you should have one fact table.
Dimensional tables can be joined to one another if the have flakes(sightly normalized table).
so you have start up the things from DWH.

How to Create a Dimension Table in OBIEE11g

Hello,
Chapter 9, page 221(if pdf) of the Build Repository manual of OBIEE 11g explains following.
Creating Dimensions in Level-Based Hierarchies
After creating a dimension, each dimension can be associated with attributes
(columns) from one or more logical dimension tables and level-based measures from
logical fact tables. After you associate logical columns with a dimension level, the
tables in which these columns exist appear in the Tables tab of the Dimension dialog.
To create a dimension with a level-based hierarchy:
1. In the Business Model and Mapping layer of the Administration Tool, right-click a
business model and select New Object > Logical Dimension > Dimension with
Level-Based Hierarchy.
Note that this option is only available when there is at least one dimension table
that has no dimension associated with it.I am still learning OBIEE, and I can not see the dimension menu item as per point 1 becuse i do not have dimension table associated with it. All I have done at this point is to create logical tables based on few physical tables in physical layer.
How do I create Dimension Tables? using BI Admin tool?
Thanks,R

Hi Rich,
If you are new to Oracle BI, you would better start with the Oracle Learning Library; http://apex.oracle.com/pls/apex/f?p=9830:41:0::NO:RIR:IR_PRODUCT,IR_PRODUCT_SUITE,IR_PRODUCT_COMPONENT,IR_RELEASE,IR_TYPE,IRC_ROWFILTER,IR_FUNCTIONAL_CATEGORY:,BI,,,,,
You create dimensions based on your logical tables. In a plain star-schema you would have one logical fact table and at least one or more logical dimension tabes attached (joined) to the fact table. Just follow the documentation and you would be good to go.
Good Luck,

How fact links to Dimension Tables.

Hi All,
Can any one explain how the ROW_WID of the dimension table and the related column in the fact table both gets populated with same values in different mapping ?
Consider if we want to develop a new fact and dimension tables, then how should i proceed for the ROW_WID and the join between fact and dimension.
Thanks in Advance.
Regards
Vishwanath

Hi
Basically in BI Apps all dims are first populated and every dim table has a row wid column apart from the primary key combination(datasourceid+integration id) .If you open a seeded mapping and you would see this row wid column is populated using a reusable sequence generator transformation.So everytime u run this mapping the row wids change..........
Now coming to the facts............as a normal rule of thumb in ETL u run the facts after all the dimensions........If you open any seeded fact mapping you will observe that every fact has a wid associated the dims it joins to.......so if a fact is joining to 3 dims then there will be 3 wids associated to each dim .These wids are again populated using a lookup on the dimension table and extracting row wid for relavant id of the dim.So u get the value of row wid of the dimension in the wid column of the fact....Please let me know if u hv questions
With Regards
Venkatesh

How to join multiple source tables and do lookup?

I have a requirement to load a target table by joining 4 source tables. Also I have to do a lookup on a domain table to transform codes and check for nulls. What will be the best approach to load the target table?
Is it possible to do it in one interface or do I need to build multiple interfaces to achive this?
My source and target database both are oracle and I am planing to use Oracle Incremental Update Merge.
Thank you

You are in the right direction by creating one interface for this transformation.
You will need to drag drop 4 source tables + the lookup table on the Sources window of Interface and then make appropriate joins.
Also, check for NULLS in the transformation. Depends what you want to do with the NULLS. If you want to ignore them, use a filter.
If you want them to error out, use a constraint.
If you want to convert them, use NVL
Start with Oracle Incremental Update and once successful, use Oracle Incremental Update MERGE.

How to join several internal tables?

Hi,
I have several internal tables. And there is a very complex LOOP to extract data from these internal tables and many other logic inside it. The LOOP is very time-consuming.
I am thinking to join these internal tables into one big internal table, to save some logic inside the complex LOOP. But as I know there is no "join" function for internal tables.
So is there any workaround method to perform a "join" operation on internal tables?
Thanks a lot!

How to join three or more blocks in a form (like master/detail)

I have four data blocks for four tables, lets call them blocks A, B, C, D
Block A is a master block and block B is a detail block, block B holds a foreign key from block A (ofcourse)
Now when i choose in a query data from block A it lists also data from detail block that is corresponding, but now.....
detail block B also holds another foreign key from block C which takes his key from block D. and
i want to make a form that will, when i query master block A, show some data from block B, C and D that is
corresponding to block A.How do i do that?
i'm using 10g and i am a begginer

In each Data Block there are three nodes - triggers, items, and relations. The relations node is what you use to link the master to the detail. If you highlight the Relations node and press create a window will open to create your "New Relation". The master block is already entered because it is the block that you are currently in. You can then pick a detail block by pressing the "select..." button or just type the name of the block in. So if you did this in block A, you would enter B as your detail block. You will then need to enter a join condition. If the PK in block A is named A_DETAIL and the FK in block B is the same name, then you can just type in A_DETAIL, press OK, and the relationship will be automatically created. If the names are different then you could put in a join condition like A.A_DETAIL = B.B_A_DETAIL (whatever the names of the blocks and items are). You can then repeat this process for every parent-child relationship.

Here's a few notes that explain how to configure the Connector Pane. I took these directly from the LabVIEW Help File.
Selecting a Connector Pane Pattern
Complete the following steps to select a connector pane pattern for a VI.
Right-click the icon in the upper right corner of the front panel window and select Show Connector from the shortcut menu to display the connector pane. The connector pane replaces the icon.
LabVIEW selects a default connector pane pattern for the VI with as many terminals on the left of the connector pane as controls on the front panel and as many terminals on the right of the connector pane as indicators on the front panel. If this is not possible, LabVIEW selects the closest match. If the VI does not have any controls or indicators, LabVIEW selects a connector pane with one terminal.
To select a different connector pane pattern for your VI, right-click the connector pane and select Patterns from the shortcut menu. A solid border highlights the pattern currently associated with your icon. To change the pattern, select a new one.
After you select a connector pane pattern, you can customize it to suit your VI by adding, removing, or rotating the terminals.
To add a terminal to the pattern, place the cursor where you want to add the terminal, right-click, and select Add Terminal from the shortcut menu.
Note: Assigning more than 16 terminals to a VI might decrease performance and reliability. Too many terminals also can reduce the readability and usability of the VI.
To remove an existing terminal from the pattern, right-click the terminal and select Remove Terminal from the shortcut menu.
To change the spatial arrangement of the connector pane patterns, right-click the connector pane and select Flip Horizontal, Flip Vertical, or Rotate 90 Degrees from the shortcut menu.
Assigning Terminals to Controls and Indicators
After you select a pattern to use for the connector pane, you must assign a front panel control or indicator to each of the connector pane terminals. When you link controls and indicators to the connector pane, place inputs on the left and outputs on the right to prevent complicated or confusing wiring patterns in your VIs.
Complete the following steps to assign terminals to controls and indicators in a connector pane.
Right-click the icon in the upper right corner of the front panel window and select Show Connector from the shortcut menu to display the connector pane. The connector pane replaces the icon.
Click a terminal of the connector pane. The tool automatically changes to the Wiring tool, and the terminal turns black. Although you use the Wiring tool to assign terminals on the connector pane to front panel controls and indicators, no wires are drawn between the connector pane and these controls and indicators.
Click the front panel control or indicator you want to assign to the terminal. A marquee highlights the object.
Click an open space of the front panel. The marquee disappears, and the terminal changes to the data type color of the control to indicate that you connected the terminal.
Note: If the connector pane terminal turns white, a connection was not made. Repeat steps 1 through 3 until the connector pane terminal changes to the proper data type color.
Repeat steps 2 through 4 for each control and indicator you want to assign to a terminal.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

How to join two Source tables

Hi
I am doing a POC on joing two MSSQL 2K source tables and populating into Oracle table.
I did not find the joiner operator and other transformation operators.
Can anyone help me in using them?
Thanks,
Ganesh

Hi,
First, just drag&drop the two source table in the interface.
Then, connect the two tables with eachother using your mouse while selecting the two columns that you want to use in your join.
Transformations can be found when selecting a field in your target datastore; you will see a screen appear in the 'properties-panel' of your interface-editor; here you can edit transformations.
Good luck ...

How to join three queries in sap bw

I can not use infoset because using 3.5 version. And in 3.5 can not include infocube in infoset.
Any suggestion.

Hi Namah
you need not do any java scripting for this. The command is enough to take care of your situation.
Perhaps an example can help you. Suppose you have Query1, Query2 & Query3 and Button1 and Button 2. Button 3
For Query1, through the item properties, set Visiblility=Visible, for Query2, set Visibility=Hidden.
Query3, set Visibility=Hidden.
This will take care of your initial situation.
Now, take button1, assign the command 'Set webitem properties'. In the command settings, set item binding=query1, and then in the next page of command settings set visibility=hidden. Now, click the button -Next COmmand-> Insert -assign the command 'set webitem properties' once again. Here, select the item binding as query2, then in the command settings, set visibilty=visible. What you have done now is assigning 2 commands to the same button, both getting trigerred with a single click.
Now, this command setting will take care of making query1 hidden and query 2 visible.
Similarly, do the settings for the button 2, with query1=visible and query2=hidden.
Now, the result will be that on clicking button1 and button2, you can toggle between your queries.
Hope this helps..
