Step-by-step tutorial for building data model

Hello,
I'm looking for a step-by-step tutorial, which will build data model in BW (data sources, transformations, cubes). So far I found only one: http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/4096b8fc-6be7-2a10-618e-b02a5e5e798f
May someone knows other tutorials?

  • Identify Entities for Logical Data Model

    Hi,
    I donno exactly this is the correct forum for this question. I believe there are database experts here to help me on this.
    I am in confusion that, phsically the data can be saved in a set of tables (4-5 tables). But different views (User Interfaces) and reports can be created from these tables.
    Assume that,
    View1 - Uses all tables
    View2 - uses only 3 tables
    View3 - uses only 1 table
    Report 1 - uses only 2 tables
    Report 2 - uses only 4 tables
    Should my Logical Data Model reflect all these view1, view2, view3, Reprt1 and Report2?
    How exactly do we need to identify the entities for Logical Data Model?
    Could you please any one help me on this?
    Thanks & Regards

  • Building data model using business modeler in demantra

    Hello.
    During this week I've been trying to build a data model using the business modeler but i keep getting an error during the process. My main problem is that I don't really know if i am making the mistake or it is a configuration problem with my demantra install. To begin with I'm trying to build the most simple of the models, 3 files or tables (tryed both) sales, items, and location, all joined by their respectives id's. So If anyone could be so kind to direct me to a tutorial with an example (besides the implementation guide) or a anything like that will be greatly appreciated.
    Thanks!
    Data tables estructure:
    Sales table:
    Item_Id|Item_Name|Org_Id|Org_Name|Site_Id|Site_name|sales_date|Quantity
    Items table:
    Item_Id|Item_Name
    Location table:
    Org_Id|Org_Name|Site_Id|Site_name
    So far I've tryed building the model with one record on each table.
    this is the error that i'm getting:

    We currently don't support DataControls based on the ADF BC technology. We will consider such support if there is a strong interest in that use case.
    Independent of the IDE's you use, there are ways to expose services based on ADF BC that can then be consumed by the view layer. A Google search will point you to some of the approaches.
    HTH. Thanks for your interest in OEPE.

  • Data Model best Practices for Large Data Models

    We are currently rolling out Hyperion IR 11.1.x and are trying to establish best practces for BQYs and how to display these models to our end users.
    So far, we have created an OCE file that limits the selectable tables to only those that are within the model.
    Then, we created a BQY that brings in the tables to a data model, created metatopics for the main tables and integrated the descriptions via lookups in the meta topics.
    This seems to be ok, however, anytime I try to add items to a query, as soon as i add columns from different tables, the app freezes up, hogs a bunch of memory and then closes itself.
    Obviously, this isnt' acceptable to be given to our end users like this, so i'm asking for suggestions.
    Are there settings I can change to get around this memory sucking issue? Do I need to use a smaller model?
    and in general, how are you all deploying this tool to your users? Our users are accustomed to a pre built data model so they can just click and add the fields they want and hit submit. How do I get close to that ideal with this tool?
    thanks for any help/advice.

    I answered my own question. in the case of the large data model, the tool by default was attempting to calculate every possible join path to get from Table A to Table B (even though there is a direct join between them).
    in the data model options, I changed the join setting to use the join path with the least number of topics. This skipped the extraneous steps and allowed me to proceed as normal.
    hope this helps anyone else who may bump into this issue.

  • Tutorial for new Data Upload feature in 4.1?

    Greetings,
    Is there a tutorial available for using the new Data Upload feature in 4.1? We have not upgraded to 4.1 yet and I would like to try out the new feature on my APEX test workspace, so I can use the new feature once we are upgraded to 4.1.
    Thanks,
    John

    I installed the Product Portal Sample Database and went to page 21. Very nice looking. Is there any tutorial for this Sample application? In other words, is there a tutorial that uses this application as its basis?
    What I am really looking for (my apologies if I have not been clear) is a tutorial that steps you through the process of setting up the new feature of Data Upload in APEX 4.1. I would like to create a new application on my test workspace and learn how to set up the Data Upload page.
    Seeing the Data Load in action is very helpful though. Thanks for pointing me to this.
    Thanks,

  • Reuse Dimdate across different database for different data models

    Hi,
    I am designing a new data model for a data mart. I need to add dimdate dimension in this data model. I noticed that dimdate already exists in another database and being used by another
    data model. Is it possible to re-use the existing dimdate table for my new data model? If so, what about the foreign key constraints? Normally we link the date columns from fact table to the dimdate keys. How would we achieve that in case we are using the
    same table across different databases?
    Any opinion on this will be highly appreciated.
    Thanks in Advance.
    Cheers!!

    You can create a copy of dimdate table to your new data warehouse.
    If both data marts were in a single data warehouse, then you don't required to copy. but as these are in two different databases then you just copy that.
    regarding FK relationship. you can connect any fact table to you date dimension. even if you want to use more than one instance of your date dimension, it would be simply adding multiple FK columns in your fact table (role playing dimension).
    For date dimension be sure that your date dimension covers most of the attributes required. here is an example of date dimension:

  • Call Multiple RTF for same data model

    How call two templates for the same data model.
    what is the logic i have to use in the rtf template.
    Thanks in Advance

    Your RTF template will use the data model you defined.
    So no logic than just inserting the xml elements your data model provides.
    You can associate multiple templates to one data model. At runtime you will have the opportunity to select
    the template of your desire to run the data against.
    If you want this process to be automated then you will have to user bursting and for that you need to read this:

  • BADI to validate data input for custom data model.

    Hi,
    I have a custom data model which has Material as the key field. When the user enters the Material number and clicks on CONTINUE, he is taken to the second screen where he has to enter data and description of the change request (the standard familiar screen). Now when the user fills the data and submits the record I need to do data validation and throw an error accordingly, Can anyone please help me out with the BADI or a solution to achieve this result.
    Any kind of help would be sincerely appreciated.
    Regards,
    Tushar.

    Hello Tushar
    Path is - General Settings - Business Add-Ins- BADI - Define Validation / Enrichment - You can check all the relevant BADI's here. Click on display and then you have filter option. Add your data model in filter. This is useful for Finance. You have check for MM.

  • Selection of Middle tier components for creating data model

    Which business layer is prefered to create interactive data model: 1. ADF business components or 2. Enterprise JavaBeans using Java persistance API (JPA) or 3. Toplink 4. Portlets
    which minimizes writing low level codes and how much OOPS knowledge is required for creating above business layer binding data to viewcontroller layer?

    Portlets is view layer.
    About business services layer:
    1. ADF business components --> Heavy DB layer, Developer not very OOPS/Java oriented.
    2. Enterprise JavaBeans using Java persistance API (JPA) --> When you are looking for portabilily across App Servers/ Developers good at EJB3.0
    3. Toplink --> Depends on developers.
    So based on skill set and requirements you can choose any one. But if you are on a Oracle stack go for ADF BC.

  • Any tutorial for building adapters and routing services for JBI container ?

    Hi
    Thank you for reading my post
    is there any tutorial for Sun JBI container ?
    I want to know how i can build/deploy JBI components like adapters and routing service for Sun JBI container .
    another question is that , is it based on OpenESB ?
    thanks

    You can find a white paper on writing a JBI service engine here:
    http://java.sun.com/integration/reference/techart/DevelopingAServiceEngineComponent-1-2.pdf
    Also, there is a lot of information on JBI and Open ESB here:
    http://java.sun.com/integration/
    You ask if the Sun JBI container is based on Open ESB - it's actually the other way around: Open ESB is based on the Sun JBI container. The JBI container is a JSR208-compliant implementation, and Open ESB builds upon that implementation to add full ESB capabilities.
    hope this helps -

  • How to build data model in Endeca Server?

    After completed the Quick Start Guide, I'm still confused about Endeca components. From the view of BI, there should be a data model built in Endeca Server, and a tool to develop and administrate the data model. Which component acts as this role, CloverETL or something else?

    We've created a "Getting Started with Endeca Information Discovery" screencast series that should provide you answers to these questions.
    You can find the full outline on our OTN page: http://www.oracle.com/technetwork/middleware/endeca/learnmore/index.html

  • Tutorial for Building Mobile Web Applications Using ADF/BC4J-problem

    This is the tutorial for:
    Develop a offline, Web-based Disconnected Mobile application
    Trying to create an offline mobile application using jdeveloper & oracle lite. I want to be able to update the home database after using the application in a disconnected fashion. I do not have a web site, nor is that a feasible option.
    Jdeveloper 10.1.3.4 which should be OK as it is higher than the release specified in the tutorial.
    webtogo
    oraclie lite 10
    oracle 10.
    I have tried to follow the tutorial completely and I can not get this to connect from webtogo. It runs fine in the jdeveloper usising the container. I created the war file, did the wtg packaging process, opened the mobile manager and published the application & granted access to user 'john'. The samples provided work fine. The new application appears on the webscreen after installing web 0c4j. When I click on it, the address toolbar shows:
    http://localhost/webtogo/bc4jtutorial/faces/CustomerOrders.jsp
    When it installed mobile client, it installed the CustomerOrders.jsp into:
    E:\mobileclient\mobile_client_oc4j\j2ee\mobileclient\applications\mobileclient\bc4jtutorial
    an example of the samples that work shows
    http://localhost/webtogo/sample6/list
    in the browser address line.
    Which looks like it's really
    E:\mobileclient\mobile_client_oc4j\j2ee\mobileclient\applications\mobileclient\samples\sample6
    on the file system
    Any one have any ideas? I'll take another solution if someone has found one. However, i am not a great java programmer so thought jdeveloper was great to create forms and access the database.

  • What kind of view object should I create for this data model?

    I have an entity that has several dates. The dates are stored in a table separate from the entity, each entity date has a date type (open, close, interview, etc) associated with it. The DBAs idea (who else of course!) was to have the flexibility to add new types of dates for entities when needed.
    So you have tables like this -
    Table: EntityTable
    Columns: EntityId, EntityName
    Table: DatesTable
    Columns: EntityId, Date, DateTypeCd
    I need to display an editable ADF form where I can update the entity and the entity dates
    The ADF form would contain something like this -------
    Entity Name: []
    Opening Date: []
    Closing Date: []
    Interview Date: []
    What kind of view object would I need to create to achieve this?

    That would be a master-detail relation 1-* between 'entity' and 'entity dates'. If your dba has set up the foreign key association in the db and you use the wizard to create the business objects, jdev pick up the relation and create the correct master detail relation in the vo layer for you.
    By the way naming a table 'entity' is not a good idea when working with ADFbc. We all talk about entities when we relate to a business object (in this case a row of a table or entity object or EO). So it's hard to distinguish the two, your specific table 'entiyt' and the common term entity or EO which can be a row of any table.

  • Creating Entities for this data model

    Hi guys,
    I have these 3 tables:
    create table employee_a
    ( employee_id int not null primary key ,
      first_name varchar(50) not null ,
      last_name varchar(50) not null )
    create table manager_b
    ( id int not null primary key ,
      manager_employee_id int not null foreign key references employee_a(employee_id) ,
      subordinate_employee_id int not null foreign key references employee_a(employee_id) )
    create table user_c
    ( user_id varchar(20) not null primary key ,
      user_password varchar(100) not null ,
      employee_id int null foreign key references employee_a(employee_id) )* All the employees are defined in employee_a table.
    * If an employee is also a manager then its defined in manager_b table. That employee's id is defined in manager_employee_id column while his/her's subordinates employee ids are defined in subordinate_employee_id column.
    * All the users of the system are defined in user_c table. If user of the system is also an employee then its defined in employee_id column of user_c table. If user of the system is not an employee then employee_id column is blank of user_c table.
    The data may be like this:
    insert into employee_a values (1, 'Mark', 'Benson')
    insert into employee_a values (2, 'Joe', 'Young')
    insert into employee_a values (3, 'Robert', 'Carbone')
    insert into employee_a values (4, 'Wendy', 'Swistenenko')
    insert into employee_a values (5, 'Tony', 'Lapolla')
    -- Joe Young is manager of "Robert Carbone" and "Tony Lapolla"
    insert into manager_b values (100, 2, 3)
    insert into manager_b values (101, 2, 5)
    -- Wendy Swistenenko is manager of "Mark Benson"
    insert into manager_b values (102, 4, 1)
    -- Users of the system who are also employees
    insert into user_c values ('bensonM', 'password', 1)
    insert into user_c values ('youngJ', 'test', 2)
    -- A user of the system who is not an employee
    insert into user_c values ('guest', 'pretty', null)My question is how to define Entities for these 3 tables for JPA. I am concerned about Inheritence Strategy to use.
