How do I design this in data warehouse?

I am working on building a data warehouse for insurance quote data.
Each quote will have an applicant and can have an optional co-applicant. Each applicant and co-applicant will have prior auto insurance history, prior home insurance history, current auto insurance information and current home insurance information.
So do I create Applicant and Insurance dimensions here?

Hi Ashan,
Just so you know.
I completely reworked our methodology of building data warehouses back in 2012. The new way of building data warehouses is quite different to the old way. The way you listed.
The methodology presentation is on this link.

I am an MSDN so we do our development on MSFT first and then deploy where ever our clients want us to deploy.

ICloud storage space used up by old data from 1st gen iPad I traded in nearly 2 yrs ago for an iPad Mini. Can't backup any info for mini or new 6 plus. How can I access this old data to clear it out?

My iCoud storage space is being used up by old data from a 1st generation iPad I traded in nearly 2 yrs ago for an iPad Mini. The people at the sprint store where I made my trade were supposed to transfer everything over from my old iPad to the new Mini once they backed up the old device to iCloud. Well, long story short, none of the data ever got transferred to the new iPad, but it all got backed to iCloud, eating up all my storage space. Here I am almost 2 years later, and I've never been able to back-up my iPad mini. What's worse, My iPhone 4 wasn't backed up that whole time, and now I can't back-up my data from my new iPhone 6 Plus to iCloud either. Trying to find creative ways to store and save my information and data between all my devices is getting to be ridiculous. I don't want to upgrade my storage space though...just want to clear out a great deal of what is already being stored. How can I access this old data to clear it out?

The only way to access data from an iCloud backup is to restore it to your device. You could, for example, back up your iPad mini to your computer using iTunes (by connecting it, opening iTunes, then going to File>Devices>Back Up and choosing to back up apps and transfer purchases when prompted), then erase it and restore the old iPad backup (as explained here: iCloud: Restore or set up your iOS device from iCloud), save any recovered data you want to keep, then restore your iTunes backup back to your iPad mini (by connecting it to your computer, opening iTunes, then going to File>Devices>Restore from Backup).
Once you're done with the old backup, delete it from your account to free up the space.

How do you link attributes in data warehouse

I am new to data warehouse and I am trying to get some direction on how tables, data is linked in the data warehouse archieture. For example in a rational database inorder to get data from several tables to print on a report I would have to join tables, or maybe have a unique field in each table that retrieves the information for that record. How does this work in Data Warehousing. I will appreciate some insight on this subject.
thanks

11616,
Welcome to the exciting world of Data Warehousing! The relational concepts you are referring to still apply in data warehousing. There are also dimensional concepts, for the data that has inherent hierarchy. And too much more to mention here.
The following resources are great places to start. They are widely recognized in the industry and are vendor independent:
1. Bill Inmon

2. Ralph Kimball

Designer Vs. Oracle Data warehouse builder

Dear all,
Currently I'm responsible of building a Data warehousing project using Oracle database. I'm trying to decide on a tool for modelling my datawarehouse. I have two options:
1) Designer: we have some experience with this tool and we are using it for our main OLTP application.
2) Oracle Data Warehouse builder: we are using this to design our ETL processes.
I want to get some advice on whether the OWB is capable of modelling my datawarehouse and of doing a retrofit action. also, I try to standardize on the tools that are using in the Data Warehouse department (currently we are using only OWB).
I will appreciate for any other advice to help in my selection process.
Best Regards,
Bilal

Hi,
In my experience this choice depends on the implementation of the datawarehouse. If you are building a "pure" Kimball style dimensional data warehouse you should be able to do this using OWB. I have architected such a DW in the past using only OWB, so I am speaking from experience.
If on the other hand you are planning to implement an Inmon style CIF, if your requirements includes an operational data store (ODS), or if you for any other reason anticipate that you are going to be doing a lot of ER modeling, then I would not recommend using the current release of OWB for modelling. (Note however that there are significant improvements to the modelling capabilities in the Paris release of OWB, so this may change in the future)
The advantage of improved maintainability when using a single tools needs to be weighted against the improved functionality if you choose a combination of the two. In the "two tool" scenario strict development and deployment routines need to be enforced to avoid that the model in Designer comes out of sync with the metadata in OWB. (Consider the effect of a developer making a change to a table definition in OWB and deploying it directly to the database without updating the model in Designer.)
Hope this helps.

Roald

How DID I get this much data on my iPod Touch 1st gen?

ITunes on my brand new MacBook Pro shows 3762 songs at 62.84 GB with 99.9999% of them being AAC encoded.
My 1st gen 32GB iPod Touch holds ALL of that data, plus 210 apps -- and everything works/___sbsstatic___/migration-images/migration-img-not-avail.png Select any song at random and it will play. Select any app and it will run/___sbsstatic___/migration-images/migration-img-not-avail.png/___sbsstatic__ _/migration-images/migration-img-not-avail.png 62.84GB of songs on a 32GB Touch?? How did I do that? Plus, it STILL has 6.7GB available/___sbsstatic___/migration-images/migration-img-not-avail.png/___sbsst atic___/migration-images/migration-img-not-avail.png It's running iOS 3.1.3. I've added songs and apps over the years without any problems whatsoever.
My wife has a 30GB iPod Video White (5th gen) -- it has 4342 songs, with 9.4GB still available/___sbsstatic___/migration-images/migration-img-not-avail.png I loaded everything I had in my iTunes, and she's been adding songs on her own. So hers ALSO has more GBs of songs on it than it was made to hold. And hers works fine as well.
Now we get a brand new up-to-date 32GB iPod Touch 4th gen (Retina Display, FaceTime, etc). It's the latest and greatest (she got it through an employee incentive point plan at Boeing). I wasn't even thinking about how much data was in the 1st gen Touch -- my brain was just saying I've got all my songs and apps in my 1st gen, so I should be able to get all of it in the new 4th gen model. They're both 32GB, and the overhead (system, etc), is almost identical (okay, the 1st gen had 29+GB free and the 4th gen has 28+GB free). Still, pretty comparable.
I tried to sync iTunes with the new 4th gen iPod Touch and it says only about 1500 songs (of the 3762 total) can be loaded. That's it. No more/___sbsstatic___/migration-images/migration-img-not-avail.png That would also mean NO apps at all.
We tried to get this explained at a One-to-One meeting AND the Genius Bar at our local Apple Store, but NOBODY had an answer.
How is it that my old 1st gen 32GB Touch can hold more than twice the GB of songs AND 210 apps at the same time, and work, while the new 4th gen Touch is doing "sorta" what's expected of it -- that is, running out of space with only 1500 songs
One possibility is that both old iPod's began their lives under iTunes 9.x. But I've updated iTunes consistently as it has moved into v10 and both older models have had apps and music added using whatever the latest version of iTunes has been released.
Could that be the reason? Has anybody heard of this before? Can anybody explain it? The guys at the store were stumped. So am I. They "apologized" and said they understood how we felt, but there wasn't any resolution to the question. Other than -- DON'T mess with the old models as long as they are working Yeah, but I'd like to see the NEW model behave the same Wouldn't we all?

No, the option you mention is/was NOT checked. When I talked to two people at the Apple store (One-to-One) and the Genius Bar, they said that it was correctly set (that is, NOT checked), considering the files were ALREADY AAC encoded.
As I posted, pretty much all of the songs are already encoded as AAC files. They have all been captured off CD's in that format, or purchased from iTunes in that format. They were transferred to the 1st gen Touch in that format, and the attempt was made to make the exact same transfer to the new 4th gen Touch in the exact same format -- with the result that barely half would transfer over to the new Touch.
One would think that it might be set one way for the older model and one way for the newer, but that's not the case. As an FYI, I DID try checking that option after the first failure of getting everything to load, but it didn't make any difference.

Struggling with how to appropriately scale this host/data display VI

Hello! I'm hoping someone can send me in the right direction on this. I've mocked up a front panel the way I intend it to look - a fill slide overlapping a waveform chart, to give the effect of a visible current value and a short history trace. The idea is to have many of these kinds of indicators on one display for an engine test stand- it allows the simple visualization of a lot of data all at once, and I am replacing an old data acquisition system with a similar display.
The meat of my question lies in how to take these indicators (which work pretty much the way I want) and duplicate the code thirty times without making a huge mess. I looked into subpanels but it seemed like that was also a complicated thing to do thirty times. Maybe it's just gonna be messy, but I hope there's some good/simple way to do this.
Making a custom control seemed like an option, but I couldn't figure out how to make the custom control contain both the waveform chart and the fill slide -- and then after that, how to make the colors alternate in the alarm state like I already have.
I'm asking before I spend a huge amount of time on it in case I need to start over!
If you think you might be able to help please have a look at the attached VI with six of these things already cloned and let me know your idea. I really appreciate it.

First of all, that's a pretty neat looking UI element you've come up with there!
To be honest, I think the most appropriate way to solve this would be to create an XControl for your UI element. It's quite an involved process if you haven't created one before but if you search for creating an XControl there's quite a lot of resources available.
If that seems a bit too involved/advanced, your idea of using Subpanels is probably the best solution - create a VI that shows the data and however many subpanels you need to display the data and load the VI into the subpanel. You'll obviously have to (an array of subpanel references works well for this) do the asynchronous calls and manage the VI references etc.
The key thing is that you will want to create your graph/slide combo only once and then repeat it where needed - either through an XControl or a reentrant VI loaded into a subpanel.

How can i convert this data(00000000) into date format(yyyy-MM-dd)

Hi,
i am using this method to convert date format from string.
public static string FormatDate(string inputDate, string inputFormat)
System.DateTime date = DateTime.ParseExact(inputDate, inputFormat, null);
string datepresent = DateTime.Now.Date.ToString("yyyy-MM-dd");
return datepresent;
its working properly,
but when input data is like 00000000 i am getting error this is not valid.
how can i convert this into date format any help..!

Have you tried the above code:
I can see it is working with both Date and DateTime destination nodes.
Map:
Functoid Parameters:
Functoid Script:
public static string FormatDate(string inputDate, string inputFormat)
string datepresent;
if (inputDate == "00000000")
datepresent = "0000-00-00";
else
System.DateTime date = DateTime.ParseExact(inputDate, inputFormat, null);
datepresent = date.ToString("yyyy-MM-dd");
return datepresent;
Input:
<ns0:InputDateString xmlns:ns0="http://DateFormat.SourceSchema">
<DateString>00000000</DateString>
</ns0:InputDateString>
Output:
<ns0:OutputDate xmlns:ns0="http://DateFormat.DestinationSchema">
<Date>0000-00-00</Date>
</ns0:OutputDate>

How to user SDDM for a multi layer data warehouse

Hi,
I'm evaluating the use of SDDM for data design of a data warehouse. My DWH will be build using 3-layer architecture with: Operational Data Store, Enterprise data warehouse layer, Datamart layer.
First two layers are relational models: ods is just a load off all sources; edwh comprises both master data and subject area in a relational model. Datamart is the top layer made in form of multidimensional model.
My question is if it's better to use a single 'design' of SDDM where I create multiple relational model and multidimensional or a different design for any layer.
Thanks
Pilot

If they all have a common Logical Model you could use one design as SDDM lets you tie multiple relational and multi-dimensional models to one Logical. (Actually you can do it all in one design without that)
Right now I am using one design to hold my source table designs, a stage table layer (like source plus ETL metadata columns), my integrations layer (EDW) and my dimensions/star schema presentation layer. The only challenge becomes if you have multiple sources that have the same tables names then you have a conflict in the relational model.
Each of my layers has a different schema name in the database so I am able to create and manage sub-views based on the schema names.That makes it possible to generate sub-view based DDL scripts easily for managing the build, and reports, etc.
Having it in one design also lets me create diagrams to show the model evolution (and data lineage) from source to stage to EDW to star.

Data Warehouse Performance impact

Hi, everyone.
I have a model that I'm designing for our Data Warehouse team.
It is a star schema (not snowflake) and it is my understanding that all of the FK fields should together define the FACT table's PK.
However, my developer doesn't want to do that... he'd rather have only the fields which define the actual uniqueness of the FACT data in the PK, leavning the other DIM FK's as attributes. He would also set up indexes on those columns, according to how the query structures needs, but he doesn't see any performance or other benefit to the structure that I'm suggesting.
What benefits can I tell him that will be realized by having all the Dimensional FK's in the FACT table's PK? Will it help query performance? Will it otherwise enhance BI objectives? Our DBA's were a little unclear on what the performance benefits would be...
Thanks for the imput!
David

Hi David,
These are probably the questions we all have to take time for when designing a system. However, if you forget we are looking at a 'star schema' and simply look at it from a data modeling perspective, you quickly realize that only the attributes (FK's) that make up the combination of attributes that uniquely identify exactly one row in the fact table can be in the PK.
Let's say for example that you add another FK to the PK even though it is not actually part of the combination that identifies one row uniquely. That would allow 2 rows to be inserted with the same combination of columns that uniquely should identify exactly one row! However, due to the 'extra' FK in the PK, this is not valid anymore, because it can be this extra FK that distinguishes both rows and allows the database to store these 2 rows without throwing a PK constraint!
When making fact mappings that load your fact tables, a lookup will be done to see if this new input data already exists. That must be a lookup on the fact table's PK. If you can keep those as small as possible (as few columns in PK index as possible) the better. Regarding performance, test with adding indexes on other columns later, when some data is loaded.
Looking back, I made this mistake myself somewhere in the past and it cost me some extra work later to 'redo' things and correct my design. The advantage is: you do such things only once. :-)
Hope this helps.

Ed

Oracle Data Warehouse DB and OLAP_OBIEE DB [OBIEE11g]

Hi Experts,
I have a problem regarding joining the 2 DB in an Analysis report.
The scenario is this:
Oracle Data Warehouse is DB_1 and OLAP_OBIEE is DB_2
DB_1
-col1
-col2
DB_2
-col3
In Analysis report when they are queried or run separately, obviously there will be a report generated.
But when this 2 DB columns are joined together in one Analysis report, I always get 'No Results'.
Please help how do I fix this issue :(
Thanks,

How can we move the 'application data\apple computers' folder to another location

We use roaming profiles and the Application Data folder is stored on a network drive with restricted space (500MB). This has not been a problem in the past but since we've been rolling out iPad's & iPhones, this restriction is becoming a problem as iTunes download's ios updates and stores device backups in 'application data\apple computers' folder (and not in the media library).
Does anyone know how we can move this 'application data\apple computers' folder to another location or force iTunes to store the downloads/updates in the media library (which can be moved)?
Thanks very much in advance for any help.

Move the iTunes Library elsewhere, launch iTunes with the Shift key held down, and point it there.

You have to remember either the BlackBerryID password, or the secret question answer. Without either, you're stuck.
Your choices are:
--Use another email account to create an entirely new BlackBerryID (with which you will lose access to any purchased apps using the "forgotten" first BlackBerryID, or
--Find the initial email you were sent to confirm the initial BlackBerryID, and in it is a link to click to cancel and delete the account. Click on that, delete the account and then you can use that same email to create an entirely new account.

The DOB stored in my iPad is wrong ,how can I fix this?

Date of birth where? In your contacts app? Just edit your contact. Tap the Edit button and change it on your vCard in the contacts app.
If that's not what you're talking about, you need to explain where you want to do this.

How could we read the XML data from a table using BODS.

Hi Guys,
My requirement is , As the OLTP system consists of a table called person which consists of a column demographics. so how could i read this XML data which is in one column of an SQL table called persons. As this XML data will populate the remaining fields in my target using BODS.
Regards,
Amjad.

Hi Amjad,
I am afraid there ain't any direct method to extract XML field from a data base.
Indirect way could be converting the whole table (instead of one field) into XML format and then extract one field from it!!
