DATA MODELER: reverse engineering from existing database

After IMPORT -> Data Dictionary
Went thru dialog and Relational Model was displayed.
Sorry,
There was not relationship shown between each entity.
Right, no Bachman lines between the boxes.
Clicked the "<<" button to create Logical Model.
Again, no lines between the boxes.
Any suggestions?

Hi,
Do you have foreign keys defined in database? Is it supported database or you use generic JDBC import?
Can you check log file for errors logged there? (it's in log directory of your installation)
You need foreign keys defined in relational model in order to get relationships in logical model.

Reverse engineering for existing database

Hi,
I have two different databases, one with my application (i.e. DB1), and the other with the designer installation (i.e.DB2).
I want to get the Reverse Engineering of my app in DB1, and I know these steps:
- Design Editor> DB Admin tab> Generate> Capture design of > Server Model.
OK, but I get the "Create Database user" form, and the database and user name as "DEFAULT".
What do I have to do?
I just want designer to reverse engineer my DB1, and I think that it will store that meta info in the DB2. Am I correct?
I have created a new workarea and container for that purpose, but should I create a "Oracle database" before capturing the server model? and that database, should be the DB1 or the DB2? both are already created, so I think that I need just the connection.
thanks.

You've basically got this right - DB1 is the database you are capturing from and DB2 contains the Designer repository into which the metadata is being captured.
Designer wants to have a database definition and a schema definition in the repository to which it can attach your table definitions. In the Design Editor use the DB Admin tab to get to a place where you can create a database definition. Create an Oracle data definition for your application database (DB1) and create a schema definition (aka User) in that database to own your tables. Then those will appear as options in the Capture design of Server Model wizard.
Yes, I know - a lot of steps for what seems to be a simple task - reverse engineer an existing database. That's Designer for you. This is one of the reasons that I say that if ALL you want is to see your database in a server model diagram, Designer is overkill. But Designer can do SO MUCH more than that - if you want to fully use it, the annoyances are worth it.

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.

What version (or build) of UML are you using? You can find out by going Tools->Module Manager, find a uml module under UML category, right click on the module and bring up Properties, build number is listed under "Expert" section. What's your system platform? JDK?
In step 9, is the target uml project selected? Do you have other uml projects open at the same time?

Copy data models and reports from BW 3.1 to NW 2004s

Hi experts,
Our client has two BW servers: BW 3.1 and BI 7. BW 3.1 contains lots of data models and reports. And the BI 7 server is newly installed.
Now we want to copy these data models and reports from BW 3.1 to the new BI 7 server. Are there any solutions for this?
Thank you very much in advance.

Hi Frank,
Sounds like a cross version transport is needed.
This is a solution we have used to do what you want to do:-
Create and release a transport as per normal.
Copy and transport the files from the source system (BW 3.1) e.g /usr/sap/trans/data & /usr/sap/trans/cofiles to the same folders on the target system.
Basis help is needed here.
From here onwards using stms_import should help you in the normal manner.
Works a treat.
Have transported the following all correctly appearing as 3.x data models in NW2004s.
DSO objects.
Cubes
Transfer/Update rules
Reports.
Cheers,
Pom

How to access data in AS 400 from Oracle database

Hi
Could you please help me on accessing data in AS 400 from Oracle database? what are the main things to do? Any private documentation or any oracle metalink note please...

Hi
Please find the details given below....Any body can help me on this please....
Issue Description: The stock status report to be developed at SATN has some information that is currently calculated and stored in the Fox/pro system. A real time ODBC needs to be done to the AS/400 system to retrieve values for the respective fields. This has never been tested before as it impacts many areas.
The DBA team need to work to establish such a relationship and a report needs to be written in Oracle to have this tested on a real time basis. Mapping needs to be developed on the Oracle side to grab the correct fields

HOW TO SOLVE THIS PROBLEM?

I cant see any join conditions in your query posted. Whats the purpose of the query above. It will just bring you a cartesian product (cross join) of tables involved subjected to filters. Are you sure this is the correct query?
The error you're getting may be because you've not yet populated DimProduct or may be because of logic you used in popultaing DimProduct causing it to miss some records which is what query is referring to in above case.

Reverse engineering from an existing database

just wondering if the SQL Data Modeler can reverse engineer an oracle 10g database, already in existence? If so, what are the steps/menu choices?
Thanks
Paul

Hi Paul,
menu path is File>Import>"Data Dictionary".
You need to define connection to Oracle database. If you use SQLDeveloper you can export your connections and import them at connections page of import wizard.Look at release notes [http://www.oracle.com/technology/products/database/datamodeler/html/ReleaseNotes.htm] for none Oracle databases.

I can't create Entity Data Model Class directly from database

I have just installed odac beta (ODAC1120250Beta_EntityFramework) and Orace XE 11g for test.
I have Visual Studio 2010 on Windows 7 32bit.
The problem is that after updating odac I can't create ADO.NET Entity Data Model class. If I try, VS2010 wizard makes me choose if I want to generate from db or create an empty model. If I choose to generate from database, the next window disappers making me return to VS2010.
The workaround is to create an empty model and then update model from database. In this way it works.
Anybody has experimented the same?...
Best regards
Francesco

A couple of things you could try:
1. Install SP1 for Visual Studio 2010.
2. Do you already have an Oracle connection created in server explorer? If not, try creating one and then create the model.

Reverse engineer from oracle database

Hi friends,
I am looking to create a diagram on my Visio 2010 using the reverse engineering feature to connect to my oracle database..Can some please post
the required steps to achieve it...Thank you

Paying close attention to this part which is hidden by default.

Can't find the database model features?
Not every edition of Microsoft Visio has the database model feature. If you cannot find the features described in the procedures in this article, most likely you have an edition of Visio that does not include them.
Microsoft Visio Standard does not include the Database Model Diagram template.
Microsoft Visio Professional and Premium editions support the reverse engineering features for the Database Model Diagram template (that is, using an existing database to create a model in Visio), but it does not support forward engineering (that is, using a Visio database model to generate SQL code).

Reverse engineering SQL (not database)

Hello,
Is it planned to provide a tool to reverse engineer SQL statements as Sourceforge's Revj (Reverse Snowflakes Joins) do ?
This tool generates an ER Diagramm from an SQL Statement without connecting to the database. a demo is available at http://snowflakejoins.com/
Nb: It works fine with statements comming from SIEBEL or Oracle BI Analytics.
Regards
PAscal

You can Reverse engineering any database that
you have an ODBC driver installed for (you can set up an ODBC link to access via the ODBC administration utility under Oracle for Windows NT). From the menu choose Generate=> Capture Design of => Server Model. This brings up a tabbed dialouge box with three source settings.Choose the last radio group item - ODBC. There you will find a choice for MS Acess v7.0 (note:type will be set for you automatically).
Much success.

EXPDP and IMPDP from existing database to new 'scratch' database

Hi All,
THis is the first time i'm trying to export and import (using datapump) from one database into a brand spanking new database.
Source/Target OS - WIndows 2008 R2 Standard
Source/Target - Oracle 11G Release 2 (same patch updates - 11.2.0.3.3)
I took a full expd of the source database.
I created the same directory structure on the target as the source. I created an empty database on the target server with the same name as the source.
I am trying to use impdp to import this full export into the target database, with the end goal being everything is the same on the target as it is on the source (users, tablespaces, data, schemas, etc...).
I am running into some errors (object already exists, a few others to mention). But my question is, is this a proper way of copying a database from one server to a new server?
Thanks in advance

How to update date in a table from another database

Hello,
I am trying to code a way to Update my Testing database from another database. In the coding below the database that has the updated data ends in Restore.
Use ClientDB_MASTER_Restore
Truncate Table ClientDB_MASTER_Testing.dbo.Activity_Tracking_AZ
GO
SELECT * INTO ClientDB_Master_Testing.dbo.Activity_Tracking_AZ
FROM Activity_Tracking_AZ
Go
I know with this Technique the table must be truncated if not deleted first. There is probably a better way to do this which I'm very open to. I'm also looking for coding that will roll back any changes made should an error occur.
As always, any help is greatly appreciated.
David92595

USE ClientDB_MASTER_Testing
go
SET XACT_ABORT ON
BEGIN TRANSACTION
Truncate Table dbo.Activity_Tracking_AZ
-- SET IDENTITY_INSERT dbo.Activity_Tracking_AZ ON
INSERT dbo.Activity_Tracking_AZ (col1, col2, ...)
SELECT col1, col2,
FROM ClientDB_MASTER_Restore.dbo.Activity_Tracking_AZ
-- SET IDENTITY_INSERT dbo.Activity_Tracking_AZ OFF
COMMIT TRANSACTION
If you find it boring to type the column lists, just find the table in Object Explorer, and drag the columns node to where you want the column list.
You need the SET IDENTITY_INSERT command if the table has an IDENTITY column.
By wrapping the code in a transaction, you are not left with an empty table if the INSERT fails. The command SET XACT_ABORT ON makes sure that the batch is aborted and rolled back in case of an error.
