Design one universe vs two universe....need opinion

Hi
Data warehouse consist of 2 Fact table F1 and F2 and 8 dimensions(3 common dimension tables and 5 others).
Fact table F1 and F2 in warehouse have three common dimension table.
I need opinion about how to arrange universe for this data warehouse.
Report consist of measure from both fact tables.
What will be right way : -
1. create two separte universe - one for each fact table.
2. use single universe and use alias for common dimension.
3. use single universe ans use context.
Regards

Hi,
Creating Two Universes will be worst option I guess because it will be more or same like the option 2 you have mentioned. But creating 2 universes will increase the overhead of maintaining two universes.
From option 2 and option 3 you can select any one for such a requirement. I guess the performance of both will be the same.
The Advantage of option two will be that it will never asks for selecting context at run time, such situation might be possible in option 3.
Also, option 2 will take less time to develop as you may not find any loops.

Rohit

  • Universe Design - one big one or several subject specific universes?

    Hello,
    We are scoping out our BO universe design for an SFA/CRM solution.
    Source data is Siebel CRM, combined with Sales data from third parties. Limited other data beyond that.
    Should we build one big universe with all the subject areas in, or should be build several smaller universes, and ensure we can report across universes (Synchronisation?)
    Also, does any one have experience of the siebel rapid marts?
    Ian

    Ian,
    Please keep in mind that the limitation is one connection per universe. So, as long as the data from two sources is merged in one database, you can create one universe.
    If it were a dimensional model then it would have been easier to create the universe. The relational schema universes can become complex, but it can definitely be done.
    Based on the information you provided, I would say one universe should work. Please let me know if you have any specific questions about building the universe.

  • Summary and Detail Fact Tables in one Universe ...

    We have a classic star Schema with a snapshot( summary table by month) and a detail activity table on Daily activity. What is best way to design a Universe to accomodate this requirement.
    1. Seperate Universe for summary Table
              This removes the functionality of Drill down, and Drill down can be only available through links in Webi Reports.
    2. One Universe for both Summary and Fact, and write logic for aggregate awareness. It will complicate the universe since we have close to 100 odd mesasures.
    Thanks

    Hi Devendra,
    Use aggregate awareness irrespective of the "complicated" matter.

  • Is it possible to find out for one universe in which reports is used?

    Hi,
    Can we find out for one universe in which reports is used?
    We have universes that we used to create different reports, InfoView reports. And we need to find out in which of them.
    Regards,

    Hi Valdete,
    You can run a query for the universe using QueryBuilder:
    http://servername:port/AdminTools
    You can find out the CUID of the universe by viewing its properties. Note this CUID down.
    CUID is the longer, alpha-numeric value.
    In query builder, run the following:
    select si_name, si_webi from ci_appobjects where si_cuid='Cuid of the Universe'
    OR
    select * from ci_appobjects where si_cuid='Cuid of the Universe' (then look for SI_WEBI.
    SI_WEBI stores the object IDs of all the reports that this universe points to.
    You can then query the table ci_infoobjects, using si_id to find details of the report.
    I would also recommend you to go through the links that Ajay has posted as this provides a better insight into QB.
    Hope this helps.

  • Trial database to design a universe

    Hi,
    Is there any trial database available for BO XI , so that I can practice designing a universe.
    I am a beginner and wanted to learn BO
    Thanks

    Hi
    you need to install the BO server in order to get the samples universes.

  • Designer and Universe Builder can't start (XI 3.1)

    I've just remove BO Enterprise XI 3.0 and install BO Enterprise XI 3.1
    And all is fine, but Designer and Universe Builder can't start. Just first screen with logo appers and then it close without any error windows.
    All other applications start and work as usual except these both.
    What could I do?

    The recommened memory for 10.1.3 when running on Windows is 1 GB RAM
    Therefore running on 384MB RAM is below the minimum supported memory requirement for JDeveloper.
    You may be able to increase the size of your Windows pagefile to see if that helps but basically you probably need more memory.

  • Assigning display order to prompts designed in universe

    Hi,
    Is there a way assigning display order to prompts designed in universe?
    Currently I have achieved it though appending numeric numbers like 1, 2...at the begining of the prompt text. But when I added a new prompt it is coming in between of the existing prompts where as I have already added a numeric value to it.
    For ex: I have following 4 existing prompts.
    1. Select Granularity
    2. Enter Data/Time
    3. Select Network View
    4. Select BSC Name
    The new prompt I have designed as 5. Select Time Zone Offset. Now this prompt is coming in between 3. Select Network View and 4. Select BSC Name prompt.
    I am surprised with this behavior. Is there a solution for this?
    Thanks,
    Sus.
    Edited by: SUS_India on Apr 20, 2009 4:18 PM

    If this is the case then "Prompt Order works as per the user:xx parameter in @prompt". As user:xx is reserved for Webi only, we can not use it in the universe while designing the prompts and can not achieve the prompt display order.
    That's why I have appended the Numeric numbers in the prompts message to achieve the order, but the behavior is different in some cases.
    For Ex:
    @Prompt('1. Select granularity','A',{'Weekly','Daily','Hourly'},mono,constrained,persistent)
    @Prompt('2. Enter date/time(mm/dd/yyyy hh24:mi:ss)','D',,mono,free,persistent)
    @prompt('3. Select Network View','A','Radio Error\NV Names Path',Mono,constrained,Persistent)
    @Prompt('4. Select BSC Name','A','RE BSC Dim\Ref BSC Name',mono,constrained,persistent)
    @Prompt('Select Time Zone Offset','A','Time Shift\Time Zone Offset',mono,constrained,persistent)
    I expect that the 'Select Time Zone Offset' prompt should come at the end as numeric values have higher priority. But I am getting this in between '3. Select Network View' and '4. Select BSC Name'.
    I don't know why:(
    Even I tried the 'Select Time Zone Offset' prompt message by appending a number like ''5. Select Time Zone Offset'. Then also it is getiing displayed in between 3rd and 4th prompt.

  • Trade-off between the one-arm and two-arm WAE designs

    We are configuring a WAE (model 512) for a branch office and I was wondering if someone could please tell me the trade-off between the one-arm and two-arm WAE designs..
    thanks..
    greg..

    if you are using WCCP then the WAE becomes the client withing the servcie groups 61, 62. In order to accelerate both vlans then apply the ip redirect 61 in on the client vlan ineterfaces to the one interface.
    If inline, you can use both 2 port groups for each client interface or trunk all to a single inetrface and configure which vlans you would like to accelerate.
    Now in terms of of using both GE inetrfaces, I would have to check. A topology diagram would help

  • Two printers need to be maintained for one key combination

    Hi Experts,
    Requirement:-For one condition record two print out has to be determined on different printers.
    As per my understanding we can maintain only one printer for any key combination here as per the requirement if some one has any idea if we can maintain two printers for the same key combination.

    Hi,
    You cannot  assign two printers to one single combination of Condition record.
    This functionality is not possible.

  • CR 4 Ent, Xcelsius and WebI - one query and two different results

    Dear Sirs,
    I'm using BO 4.0 platform and 3 tools: Crystal Reports for Enterprise, WebI and Dashboard Design (Xcelsius).
    I have one question, because in my opinion in this solution is one inconsistency.
    I have one table in SQL Server (like below):
    IDRec (autoinc)  | Col1 (varchar)   | Col2 (int)
    1      A    1
    2      A    1
    3      B    2
    4      B    2
    I have one universe with ONLY 3 dimensions (IDRec, Col1, Col2). I haven't any measures.
    And:
    1. Using CR 4 Ent and I create report using 3 dimensions (IDRec, Col1, Col2).
    I make sure, that I selected option: "Retrieve duplicate rows"
    If I have 3 columns in details I have 4 records (4 rows) in my report, when I have 2 columns (Col1 Col2) I have only 2 records (2 rows) in report (Page view).
    So universe (or something like this) use option DISTICT (I think).
    2. When I use WebI (14.0.2) I have the same situation.
    3. When I use Dashboard Desigm (Xcelsius 2011) I have 4 rows !!!  ALWAYS - it doesn't matter I selected "Retrieve duplicate rows" or not  !!!
    When I look to "View script" window, I not see DISTINCT clause.
    Am I doing something wrong?
    I can change the settings so as to be able to see duplicate records?
    It's very important for some calculation, especially in Crystal Reports (for Enterprise).

    Hi,
      Thanks for the response...But the result is deviating from the expected..
           expected is
         if we have first query returns              second query returns
                  1                                                     4
                  2                                                     5
                  3                                                     6
         these two queries result should be in one table , with first query result in first column and second query result in second column.
       The two queries fetching data from same table(category table as in my post) with different search criteria( in where clause).......Regards,
    Rakesh.

  • Splitting one message into two files

    Hi all,
         I have a case where I have to generate two files for a single incoming message.The scenario is as follows-
    I have the following structure as target -
    - Structure 1 with some fields in it
    - Structure 2 with some fields in it
    I have done the mapping of the target with the source.
    Now what I require is a separate file for structure 1 and another file for structure 2
    Thanks,
    Sandeep

    You need to use BPM for this.
    First create a message mapping with one source and two targets.
    To add more message types to a mess map, go to the Messages tab (there are 3 tabs: Design, Test, Messages ).
    Then you need one transformation and two send steps in the BPM.

  • Is it possible to print one document to two printers?

    I need to print one document to two printers at the same time.
    Can I accomplish this with printer pools in OSX Server?  I've found several 3rd party vendors for Windows, but nothing for the Mac.
    Any help would be great!
    Thanks!
    Josh

    Thanks Alec!
    Is there a way to get the print pool to print to both printers at the same time?  With the pool it just switches the jobs between the two right?
    I actually need to click Print once, and have it print on both printers.
    Thanks for your help!
