Historical Data Models

I'm looking for case studies on historical data models, because I'd like to know how other analysts had overcome this subject.
Please, can anyone help me?. Thanks

I'm looking for case studies on historical data models, because I'd like to know how other analysts had overcome this subject.
Please, can anyone help me?. Thanks There is a book by Oracle Press about "UML and Oracle 8" (don't know the exact title) where UML vs. ER modeling is presented.
Thru the book you can find a chapter about "Historic Data Modelling". Try a search on Amazon, you'll find the book for sure.
There is also a book "Developong Time-Oriented Database Applications in SQL" by Richard T. Snodgrass.

BI Beginner

Hi
Run the full load IP from PSA to ODS with selections on 0CALDAY(give one year selections)
make this full load as repair full request.In display mode of IP, in menu bar click on scheduler --> select repair full --->check the option and click ok.

Historical data from ACE20 load balancer modules

Hello,
I am trying to get some historical data from our ACE20 load balancer modules which are housed in a 6504, but cannot seem to find where to get this information from. I would like to get information such as memory used, CPU active connections, throughput, http requests etc over the past month, is there any way that I can do this? I am using ANM 2.0
Thanks

Hello,
Below are teh steps to load from DB connect.
Just go to Rsa1->modeling->source system->double click on the source system. On right habd side side right click on the topmost node.now it will take u to a screen, there u can give the table name (if u know) or just execute. it will display all the tables u have in Oracle. there double click on th eselected table and select the fields requared and now generate data source. now come back to RSA1->source system-> replicate the data source. now assign infosouce as usual.And create infopackage and start the load.
And this doesn't support delta process.

What is the best workflow with SVN and Developer Data Modeler.

I am workin on strategy to fullfill next tasks with Data Modeler:
* Posibility to work on paralel branches for model
* Merging changes from different branches
* Generating upgrade scripts for changes (from one commit till other)
* Maintaining posiblity to fast build empty database for any version of model
What are your ideas?
Do you use some database for thease operations or you do it only using Modeler?
Does SVN merge works fine with Modeler?
How you work with versioned Modeler and many versions of different development DBs.

Hello,
We work with SVN and DM too, but do not use branches for DM to prevent merges.
If multiple developers work on the same design, each developer checks out the design. A lock can be used to prevent the update of the same object by multiple developers (if you want).
If you commit changes in SVN, the other developers get informed on these changes by the 'Pending changes'. They can decide whether or not they include those changes.
If you synchronize with the other developer changes, you can create alter or create scripts by importing the target database and generate scripts.
If you want to build a historical version of the model, you check out a version of the design with a specific revision (you can specifiy this during checkout). You build create scripts based for this version.

Business - Data Model

Hello All,
I have to prepare a Data flow in SAP BI for one of the Insurance system application.
There are 4 flat files coming from the source. Each flat file has records on insurances details like policies and so on.
Each flat file represents a line of business. Now the data model is newly being made. There will also be historic data for last three years for reporting and current year data is loaded in monthly basis.
Also the error records will go in different target for reporting for each line of business.
Please suggest a data flow which which would be made in best.

Design issue - Historical data - referencial integrity

Hi,
I dont know if this is the right place to post this question, but
I would to like know about the design issues in storing historical data .
I have a historical table about events ( notifications, alarms, etc ).
In historical table would I store fields with foreign key to the master table ( device table ) ?
In this design , how handle then updates ( remove record ) to the master table ?
would I have a trigger to update the historical table too ? Or I mustn' t permit
updates in master table primary Keys ?
And about no store The foreign keys in the historical data ?
What are the disvantages of this model ?
Thank you,
Faria

Faria,
The answer depends on why you want historical data.
Is the historical data to be used for auditing or legal purposes?
Are you trying to move historical data for performance reasons?
Is there some other purpose?
If you're doing this for auditing purposes, I don't recommend using foreign keys since you won't easily be able to capture delete activity.
I mostly use Designer for all of our designs and typically will turn on server side journaling for this purpose. Designer will then generate the journaling tables and write the triggers to manage the whole process. You don't even need to be a programmer to figure it out.
Let me know back if this isn't your purpose or you need clarification.
Thanks, George

What are advantages including DSO in Data Modeling?

Hi,
I want to know what are the advantages of using DSO in data modeling?
Thanks,
Sri Arun Prian.

Hi.......
DSO is mainly use for data staging.............DSO has the overwrite option which we cannot get in Infocube.......
Seen from a datawarehouse perspective the usage of ODS is essential if You wish to build Your DW architechture according to the principals of enterprise datawarehouse (short EDW).
In general there are several advantages of building an Enterprise structure but most importantly:
1) With the ODS You secure that You only extract data from the source once thereby reducing the performance load on the source. Data can be populated internally via the ODS object to reuse the extracted data.
2) With delta it is very easy to reestablish a delta load from the ODS to the Datamart (InfoCube).
3) With the ODS in place You can reduce the amount of data available in the Datamart thereby improving performance on You reporting structures.
Notice that according to the Enterprise principals it is very important not to mix up an enterprise layer (ODS) with a staging layer. Typically the staging layer will be flushed after 1 or two days. The enterprise layer contains all historical data as long as required.
Hope this helps.........

Debjani.........

Excel Workbook with Excel Data Model stored on SharePoint - daily refresh

I'm not sure if this is exactly the right forum but I'm hoping that someone here can either answer or point me in the right direction.
I have an Excel Workbook with an Excel Data Model.
The Excel Data Model uses SQL to contact our data warehouse and pull through data into tables.
We are storing the Workbook on a SharePoint site and viewing it using Excel Services.
The data in our data warehouse is updated daily and so I would like to refresh the workbook daily and remove the option to refresh the data in the browser.
Is this possible with a workbook that has an Excel Data Model (I've seen lots of posts that relate to workbooks with connections to tabular models).
Thanks
Paul

Issue while creating Data Model in BI Publisher and logging into xmlpserver

Hi All,
We are facing an issue in OBIEE 11.1.1.5.
If we are logging with Non Admin Id (other than weblogic) and select New Data Model, a blank screen is coming. Where as, if we use Admin Id, we are getting screen as usual for creating data model. There were some blogs mentioning to change Priviledges for SOAP access, but that approach is also not working.
Further, we are also not able to open xmlpserver with Non Admin Id.
Any help or pointers would be great.
Regards,

how about pasting the content of your data template here, so that forum members can see what could be the problem.

2) In options to manage the Table report (Reports -> Manage). Currently I can only remove a heading (like Descriptions Notes ,columns,column comments.). Is there is any way to customize the report in such a way that I can remove some columns (mostly the empty ones) from the report and add the column comments along with the column table than a new column comments table.
Please let me know ,is there is an option to customize the report .
Note: I even tried generating the report using the search then report , but it doesn't give a complete report (i was only able to generate a report on column or table name or constraints , not all together.)
Thanks,

Can "trigger" management be addressed in the data modeler?

Please add an easier way to add/modify triggers.
I reverse-engineered my model into the data modeler and my triggers all migrated correctly to the model but, for the life of me, had no idea how to view, modify or create triggers. After extensive research, I found that they can be accessed in the left-hand Browser by drilling some 8 levels to view the triggers for each table - why? Why can't this functionality be added to properties context menu for the table. I'm not a big advocate for triggers but if I need to work on one, the current methodology is tedious at best.
Of course, if there's some other way to do this, please inform...
Accessing Triggers via the Browser
Design -> Relational Model -> APEX_DEMO -> Physical Model -> Oracle Database 11g -> Tables -> ACTIVITY_LOG -> Triggers

Thanks Joop and Phillip...
While I occasionally use SQL Developer, I currently use PL/SQL Developer (Allround Automations) as my development tool of choice and bringing a 3rd tool as SQL Developer into the mix, makes no sense to me.
I completely agree that managing a trigger via a development tool is much easier but one occasionally wants to quickly add a trigger either manually or via a template and this is not easy currently.
While functions, procedures, package, etc. are all important to a data model, the existence of most triggers are completely dependent on a table and are a critical component in any model that uses them. The ability to access and modify them easily in Data Modeler is important and shouldn't be an afterthought as is perceived here. If trigger access cannot be added to the Table Properties (as noted in the image below), at the very least, please provide a shortcut methodology to do so.

Not able to save a newly created Data Model in BI Publisher.

Hello everyone,
I was trying to create a new Report (my very first report) in BI Publisher. I created a new Data Model and a Data Set. But I am not able to save the Data Model and thus not able to proceed to the report. There's no error shown. Same happens with reports too.
Kindly provide me with a solution.

You should have a group called 'XMLP_ADMIN' in your repository and administrator or the user you are using should be part of that group. Look into paint.rpd for all these.

i need to to pull data in bw from r/3 for frieght rates
example for rate is from source to dest(in rows) and on the basis of this we have counditon types(in columns) which we will put in coloums and on the base of those cound type we will get cummulated value of master data rate.
like
source dest rate(based on coundition types)
now in r/3 some coundition type are changed to new ones or we can say merged to new ones, now my question for new one i can pull no problem but what i'll do for the historical master data like coundition type in 2006 are diff and 2007 is diff
but they mapped in each othe

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
