Modeling Data warehousing elements in Rational Rose
Hi
I am working in Datawarehousing project. we are using Oracle warehouse builder 9i and Oracle express 6.3.4.
Warehouse builder: WIn2000
Express: SUnsolaris
Database: oracle 8.1.7
can i model the datawarehousing elements in Rational rose...
because Datawarehousing and OLTP are going in parallel. we would like to know the changes done in OLTP tables.Suppose if any change happens in OLTP table, i will have to estimate the effort of ETL work. Is there any way modelling can be done for Datawarehousing elements with OLTP tables.
your inputs are welcome.
Thanks
narasimha.
Narasimha,
Although I we are working on a metadata integration solution that will also accomodate Rational Rose users, at the moment I would strongly suggest that you do the warehouse modelling in OWB.
Regards:
Igor

UML Modeling / Reverse Engineering Tool: Rational Rose orSELECT?
Can anyone comment on the relative strengths and weaknesses of the Forte
modeling / reverse engineering tools from Rational and SELECT? A brief
discussion of tools for reverse engineering Forte applications appeared in
June '98, but it was not clear how these products compared.

Rational Rose 8 exporting model to JDev
Hello ,
I'm trying to figure out how to export my Rational Rose project to JDeveloper.
I can't find any way to it.

Reverse engineering with Rational Rose
Is anybody using the above?
If so, have you developed any scripts to facilitate updating the Rose model,
and which you'd be willing to share? Or perhaps discuss jointly writing
same?
Ideally, there would be an Fscript to facilitate exposting Forte projects,
and a Rose script to facilitate import.
TIA,
EricEric,
As part of tool evaluation for modeling, We evaluated Rational Rose 98i . We
were able to import forte pex files into Rose model.
We had no problems with reverse engineering but there were problems related to
round trip engineering.
Since Rational Rose 98i did not have a repository based solution for
configuration management, it was quite a task to keep the model in sync with
multiple users updating it. However, I believe you can use Microsoft Source
safe for configuration management though we did not try this.

Re: Rational Rose product and Forte
We use Forte 3.0 with Rational Rose 4.0 since more than one year on a
medium size project (10 developers). I have not tried Rose98 with Forte,
so what I have to say may or may not apply to Rose98.
In general I am very satisfied with the Forte support of Rose. The code
generation facilities are sophisticated. For example from one attribute
in Rose you can generate a virtual attribute and the corresponding get
and set methods which implement the virtual attribute. You can even
change the naming conventions (how to generate the name of get and set
methods). You can also model all components of a Forte application like
interfaces, events, eventhandlers, constants, domain types etc.
Since access to the Forte repository is difficult, Rose does not read
from or write to the repository. Instead you must export a plan as a
.pex file, regenerate the plan from Rose and reimport the generated file
into Forte. Rose correctly preserves the code that you have written as
well as other information like GUI layout etc. Nevertheless this process
is a bit tedious and prone to errors.
Rose can import a Forte .pex and produce a model from it ("reverse
engineering"). This works O.K. but I use it only on small prototypes
that I developed in Forte to get a "first cut" of a model. The analyzer
has only a few global options (for example whether you want to model
object-valued attributes as associations or as attributes). In addition
it names all attribute types and method parameters with fully qualified
class names so that your methods tend to have very long signatures like
Add(input source:Framework.IntegerData):Framework.IntegerData
instead of
Add(source:IntegerData):IntegerData
On the other hand Rose generates correct Forte code if you use the short
form in your model. So I use Rose mainly for forward generation.
I find the combination of Rose with Forte very valuable, mostly because
Forte does not allow a convenient documentation of plans, classes and
attributes.
If you have additional questions, I will be happy to answer them.

Oracle 9i JDeveloper & Database & jdk 1.4 & Rational Rose 2002
I am not sure if this is the place to ask these types of questions, but i am goin to ask anyway
Here is my situation, I am doing a project with Rational Rose UML model. The program is written in Java, I wanted to use Rational Rose 2002 for UML model, JDeveloper for coding and Oracle Database
1. After i downloaded Oracle 9i JDeveloper, the program said its certified for JDK1.3.1_02, is it safe to use JDK1.4.1_1 with it?
2. Can i use 9i JDeveloper with Oracle 8i Database or its best to use 9i JDeveloper with Oracle 9i Database?
3. Since Rational Rose 2002 only has Oracle 8 dataType, should i use Oracle 8i with it? or Oracle 9i will work anyway?
Please help and email me at [email protected]1. To run JDeveloper use jdk1.3 but you can use it to develop applications with jdk1.4
2. You can use Oracle9i JDeveloper with Oracle8i.
3. Oracle9i will probably work, but rational might not be able to take advantage of the latest features of the database. Check out the UML capabilities of JDeveloepr. -
Data warehousing workbench in SAP 6.0
Hi,
I want to learn to work on Data warehousing workbench in SAP 6.0. The course fee for it is very high so i am thinking of learning it online. Can anyone guide me how to start and from where to start?
Thanks
ArpitHi,
first enter the t code - RSA1 in bw system - it is the modeling screen.
but in BW 7.0 we are not using the info source it is the optional
we are using the data source.
please fallow the below steps.
I am thinking if your are loading the data through flat file (excel form.CSV)
creating info area
creating info object catalog
creating char and key figures
creating the data source -> info package - once run the info package you will see the data in PSA
after create the DSO and CUBE
then after create the transformations -> it will map the form source to target.
run the DTP -> after running the DTP data move form PSA to CUBE.
if you don't knowledge on SAP BW take the help with your BW friends
hope it will help.
Thanks,

Rational Rose TopLink Integration
I'm about to start a new project hosted on OAS and looking for Object-Relational Mapping Tools.
I want to follow a Model Driven Architecture (MDA) methodology, using UML as the master definition of the persistent model.
The questions I need to know about Oracle TopLink is as follows :-
i) Does a project generated from Rational Rose work with Oracle TopLink
ii) Does Oracle offer an alternative modelling tool.
ii) Does Oracle TopLink provide an incremental DDL generation tool, i.e. only generating alter statements to existing schema
Many thanks

Hi Jain,
Data binding enables data transfer between views and models, so that we don't have to add or change controller coding to work with models.
Syntax for DataBinding:
For <htmlb:InputField>
<htmlb:InputField value="//query/a"/>
This example code creates an inputfield that takes its initial value from the a attribute of query model.
here query is the instance for model we can define in conroller Do init method.
For ex if you want to add two numbers by using model data binding.
Create method add in model which has three attributes value1,value2, and result.We have to define these attributes in model.Result is to print the added vaue.
Then we have to add these values to the model in the view by using above syntax:
<htmlb:InputField value="//query/value1"/>
<htmlb:InputField value="//query/value2"/>
<htmlb:InputField value="//query/result"/>
here query is instance for the model.
Here you have to remeber one point that no need to define these attributes(value1,value2,result) in the view again but you have define model instance in the attributes of view.
Try using this concept..........
Reward points if useful.Hi Anubhav,
Model Data Binding in business server pages ensure that data which is entered by the user in
the user interface(view) automatically passes to the model attributes and also output from the
backend system automatically passes to the result view.
So we need n't handle the data which is going to backend or the data which is coming from
backend system.
Data binding takes care of all the data handling .so we need n't write code to handle the data.
All i can say is data binding means binding the UI elements with the model class attributes.
If data binding is not available in BSP, we would have written lot of code in controller class
of business server pages.
I am giving simple example here to make you understand.
The initial view in this application contains 2 input fields, 4 radio buttons and 1 button.
Here radio buttons named Add, Multiple , Subtract and Divide.
The functionality i this application is whenever user enters numbers in input fields and select on
radio button and click on button , the result has to be displayed in the result view.
Initial View:
<htmlb:content design="design2003">
<htmlb:page title = " ">
<htmlb:form>
<htmlb:textView text = "value1"
design = "EMPHASIZED" />
<htmlb:inputField id = "f1" value = "//model/v1" />
<htmlb:textView text = "value2"
design = "EMPHASIZED" />
<htmlb:inputField id = "f2" value = "//model/v2" />
<htmlb:radioButtonGroup id="rbg" selection="//model/s" >
<htmlb:radioButton id="id_add" text="add"/>
<htmlb:radioButton id="id_sub" text="sub"/>
<htmlb:radioButton id="id_mul" text="mul"/>
<htmlb:radioButton id="id_div" text="div"/>
</htmlb:radioButtonGroup>
</htmlb:form>
This code in the above view shows the data binding;
<htmlb:inputField id = "f1" value = "//model/v1" /> and
<htmlb:inputField id = "f2" value = "//model/v2" /> and
<htmlb:radioButtonGroup id="rbg" selection="//model/s" >
Here v1,v2 and s are model class attributes . model is reference variable of model class .model is declared
as page attribute in BSP.
As i said above automatically the values of inputfields are passes to the model class without writing the code.
Code in model class method:
METHOD toall.
IF s = 'id_add' .
v3 = v1 + v2.
ELSEIF s = 'id_sub'.
v3 = v1 - v2.
ELSEIF s = 'id_mul'.
v3 = v1 * v2.
ELSE.
v3 = v1 / v2.
ENDIF.
ENDMETHOD.
</htmlb:page>
</htmlb:content>
Result View:
<htmlb:content design="design2003">
<htmlb:page title = " ">
<htmlb:form>
<htmlb:textView text = "output"
design = "EMPHASIZED" />
<htmlb:textView text = "//model/v3"
design = "EMPHASIZED" />
</htmlb:form>
</htmlb:page>
</htmlb:content>
Here the result is available v3 attribute of model class and it is binded to the text view of the result view.
Finally the result is displayed in result view.In the above example i didn't explain about controller class
I hope you know about controller class.
Hope it helps.
Reward points,if found useful.
Thanks,

What is summary level concept in data warehousing?
I am new to data warehousing.
can anybody explain about the summary level and higher level concepts in data warehousing?If I understood your question:
Data warehouses are intended for analytic processing (OLAP). Basically, It's based on queries that would take too long in OLTP (transactional processing). So you build a new Database, with a relatively denormalized model (you probably have heard about Star-Schema modeling, etc).
Look for Bill Inmon (Building the Data Warehouse) and Ralph Kimball (The Data Warehouse Lifecycle Toolkit : Expert Methods for Designing, Developing, and Deploying Data Warehouses) Data warehousing concept books. Mr. Inmon and Mr. Kiball pretty much "created" the Data Warehousing concept. You'll also find a Book from Oracle Press, named "Oracle XX Datawarehousing Guide" (XX = DB Release).
Also, you have plenty documentation about how to create a data warehouse in OTN. See thread below:
OLAP and cubes tutorials
Hope it's useful for you!

pls help me in knowing the differences between database and data warehousing in detail
send me links and PDF if u have
thanksHi,
A data base is a structured collection of records or data. A computer database relies upon software to organize the storage of data. The software models the database structure in what are known as database models.
A data warehouse is a repository of an organization's electronically stored data. Data warehouses are designed to facilitate reporting and analysis.This classic definition of the data warehouse focuses on data storage. However, the means to retrieve and analyze data, to extract, transform and load data, and to manage the dictionary data are also considered essential components of a data warehousing system. Many references to data warehousing use this broader context. An expanded definition for data warehousing includes business intelligence tools, tools to extract, transform, and load data into the repository, and tools to manage and retrieve metadata.

Good books for BI data warehousing ?
hi there,
i visited BW310 and BW305 course at SAP. i am new in SAP BI (i am coming from SAP R/3, with experience of over 7 years)
