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
http://www.billinmon.com//library/articles/article2.asp#General
2. Ralph Kimball
http://www.rkimball.com/html/articlesfolder/DWfundamental.html
Almost vendor independent:

How to update link and import data of relocated incx file into inca file?

Subject : how to update link and import data of relocated incx file into inca file.? The incx file was originally part of the inca file and it has been relocated. ------------------- Hello All, I am working on InDesignCS2 and InCopyCS2. From indesign I am creating an assignment file as well as incopy files.(.inca and .incx file created through exporing). Now indesign hardcodes the path of the incx files in inca file.So if I put the incx files in different folder then after opening the inca file in InCopy , I am getting the alert stating that " The document doesn't consists of any incopy story" and all the linked story will flag a red question mark icon. So I tried to recreate and update the links. Below is my code for that //code start***************************** //creating kDataLinkHelperBoss InterfacePtr<IDataLinkHelper> dataLinkHelper(static_cast<IDataLinkHelper*> (CreateObject2<IDataLinkHelper>(kDataLinkHelperBoss))); /** The newFileToBeLinkedPath is the path of the incx file which is relocated. And it was previously part of the inca file. eg. earlier it was c:\\test.incx now it is d:\\test.incx */ IDFile newIDFileToBeLinked(newFileToBeLinkedPath); //create the datelink IDataLink * dlk = dataLinkHelper->CreateDataLink(newIDFileToBeLinked); NameInfo name; PMString type; uint32 fileType; dlk->GetNameInfo(&name,&type,&fileType); //relink the story InterfacePtr<ICommand> relinkCmd(CmdUtils::CreateCommand(kRestoreLinkCmdBoss)); InterfacePtr<IRestoreLinkCmdData> relinkCmdData(relinkCmd, IID_IRESTORELINKCMDDATA); relinkCmdData->Set(database, dataLinkUID, &name, &type, fileType, IDataLink::kLinkNormal); ErrorCode err = CmdUtils::ProcessCommand(relinkCmd); //Update the link now InterfacePtr<IUpdateLink> updateLink(dataLinkHelper, UseDefaultIID()); UID newLinkUID; err = updateLink->DoUpdateLink(dl, &newLinkUID, kFullUI); //code end********************* I am able to create the proper link.But the data which is there in the incx file is not getting imported in the linked story.But if I modify the newlinked story from the inca file,the incx file will be getting update.(all its previous content will be deleted.) I tried using Utils<IInCopyWorkflow>()->ImportStory() ,But its import the incx file in xml format. What is the solution of this then? Kindly help me as I am terribly stuck since last few days. Thanks and Regards, Yopangjo

How do you remove back up data from the memory storage? my storage data states that i have over 80gb of data used for back ups and i dont know why as i use a external hard drive as a time machine .now my 250gb flash storage is nearly full

how do you remove back up data from the memory storage? my storage data states that i have over 80gb of data used for back ups and i dont know why as i use a external hard drive as a time machine .now my 250gb flash storage is nearly full.. HELP!

When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.

How do you edit out the date and time stamp from a photo

How do you edit out the date and time stamp from a photo

You can blur it out with retouch
The built-in "Retouch" brush in "Edit" mode should suffice, if the background is mostly uniform, and if you set the size of the brush to slightly wider than the bar width of the letters. For example, in this picture I removed the year from the date (in the lower right corner) by using the "retouch" brush and following the contours of the letters. (the screen shot is from iPhoto '11, but iPhoto 9 should give similar results).

How do you link 2 text boxes in new pages

How do you link two text boxes in the new pages. The old one was much easier to use.

I think this is impossible! Ive been trying today and I couldnt do it. Then I opened up an old document that had text linking in it and I got a message telling me that the text boxes were now unlinked! Why would you remove that? For me this software is now useless. How on earth do I get my old version back?

Personally I think you are going about this all wrong. I believe someone recommended to you in a previous post to look into the HTML5 ( http://forums.adobe.com/thread/874917 ) you need to end up creating the site with Adobe AIR as opposed to the way you are going about doing it. That would be creating an application like Tweetdeck that connects to the internet and uses interactive elements. http://www.adobe.com/devnet/air.html
If you want to link a file within a Flash document you would receive a quicker and more in depth answer in the Flash forum as it will require ActionScript.
http://forums.adobe.com/community/flash
It sounds like you have a ton of ideas, but your lack of information suggests that 1. you don't have all the knowledge necessary to get the project off the ground and 2. your reluctance to share it suggests that you have an idea that you feel the program is proprietary. Given that this is the case you might be best served looking for an experienced Flash or AIR developer to help get your ideas going in motion. There is nothing wrong with trying to learn but the information you are giving up to go on is very broad and unfortunately it does not appear that you are getting the answers you are looking for.

How do you link a pdf. document within a Keynote slide?

How do you link a pdf. document within a Keynote slide?

Gary, I'm trying to save a Keynote presentation that was created from a Powerpoint presenation using PDF files.
It imported beautifully, problem is it won't play. Keeps giving me a "Keynote cannot play your slideshow because an error occured" message.
I thought it was a Powerpoint/Keynote incompatibility thing, so I recreated the presentation - 1 pdf per slide just like you have here (I did this before finding your post) and it still wouldn't play. I even tried JPG - nothing; just horrible looking images.
Is there something I'm missing?

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.

How do you auto populate a date in a different text field after someone digitally signs the PDF form?

I am trying to auto populate a date in a text box on the upper right hand corner of my document after someone digitally signs it. Is this possible? How do you do this?

Go to the Properties of the Digital Signature field and under the Signed tab enter this JS code, under the last option:
this.getField("SignDate").value = util.printd("mm/dd/yyyy", new Date());
this.getField("SignDate").defaultValue =this.getField("SignDate").valueAsString;
Of course, you can adjust the field name and the date format used in the script above.

How do you know what the data usage was for and why? It shows you date and usage but not the reason.

How can you see what data usage was for on the bill? It only shows the date and usage but not the reason for the usage.

You can not see this info on VZW's site. There are apps for smartphones that will break down the info though, but by site or what was downloaded

Hi turintest2
Thanks for taking the time to respond - however your reply didn't really help as you haven't explained how to delete the compilation album that had been created.
I managed to sort it out by doing the following (I'm posting this so that it may help others). I don't know if this is the simplest/most elegant solution - but it works.
In iTunes, find the compilation (in my case, the 153 songs) and, starting with the first song, follow this procedure:
On the iPhone go to 'Songs' and scroll down the list until you find the first song that was listed in iTunes (above). You should notice (as in my case) that the song will have the correct title (and artwork too if you'd found this previously before making the compliation) but the wring artist.
Swipe LEFT and press the 'Delete' button.
Repeat with second song in iTunes list, deleting the individual songs from the iPhone, one by one.
Although tedious, this seemed to work for me. Reason for doing down the iTunes list is that it is in a pseudo-alphabetical order and I wanted to make sure I'd got every one.
Now busy re-importing the original albums from CD.
Thank you APPLE for making this such a laborious process. Why can't designers actually TEST the products they design so that they can appreciate first-hand the likely problems?
Anyhow, thanks turintest2 for trying to help me - it was appreciated.

How do you set the expiration date of a secure zone?

I am trying to set up a form where a user can sign up for access to a secure zone for 1 year. How do I set the expiration date of the secure zone for them to expire one year after they sign up for it?
I have tried using a hidden field named "ZoneExpiry" (I have tried "ExpiryDate" as well) in the form and set its value attribute manually in the HTML (with the format 13-May-13), and the expiration date always ends up being 31-Dec-9999.
Any help would be greatly appreciated.
Thanks!

I have done this.
Have a hidden input field on form <input name="ZoneExpiry" id="ExpiryDate" />
Then have a function as follows:
var dat=new Date();
 dat.setDate(dat.getDate() + 365);
 var monthname=new Array("Jan","Feb","Mar","Apr","May","Jun", "Jul","Aug","Sep","Oct","Nov","Dec")
 var pretty = dat.getDate() + "-" + monthname[dat.getMonth()] + "-" + dat.getFullYear();
 jQuery("#ExpiryDate").val(pretty);
Hope this helps.
