Splitting huge Schema/E-R Model into Modular Schema/Multiple E-R Models

Hi,
Currently we have huge DB Schema (1500+ Tables) using 1 single OWNER ID.
Based on Domain Partitioning,we intend to create 6 new OWNER IDs (based on individual Module/Domain)
and re-assign the appropriate Tables into the respective Domain.
basically we expect 1500 Tables under one OWNER ID would now be split
into 250 Tables per OWNER ID with a total of 6 new OWNER IDs being created.
We also will need to create 6 new E-R Models ,1 per OWNER ID
Trying to find out what could be the best possible way to do the "splitting" of a
linear huge Data Model, into 6 modular E-R models. Going forward, we would like
to maintain individual Models on per Domain basis rather than the existing monolithic Model.
Any suggestions or tips on achieving this using SQL Developer Data Modeler would be greatly appreciated.
What is the best and clean way of achieving this
Thanks
Auro

Hi Auro,
first you should be aware that you can have foreign keys created only between tables in one model.
If this is not restriction for you then you can proceed:
1) create one subview per future model and put in each subview tables that will constitute the model
2) each model in separate design
- use "Export>To Data modeler Design" - select subview that you want to export and only objects belonging to that subview will be exported

  • HT201066 How can I split a long recording audio file into multiple audio files?

    Hi,
    How can I split a long recording audio file into multiple audio files?
    With Windows I was using Nero software, which is not available for Mac. Is there any similar app for free for Mac?
    Thanks!

    Hello ingiorgio
    You can import the track into GarageBand and then split the tracks there. Once that it is done you can highlight the ruler section and then share the song to iTunes to get them separated out.

  • ITunes splits songs from the same album into several albums, all sort fields appear to match. Any suggestions on how to put them in one album?

    iTunes sometimes splits songs from the same album into several albums, all sort fields appear to match. Any suggestions on how to return them to the proper album?

    Generally all you need to do is fill in an appropriate Album Artist. For more details see my article on Grouping Tracks Into Albums, in particular the topic One album, too many covers.
    N.B. Giving different things the same sort value (or indeed vice versa) tends to lead to trouble.

  • "Place into Photoshop" with multiple files

    I'd love to see this feature in Bridge
    Import multiple files into an existing photoshop file (with a predetermined size ) as smart object layers in photoshop.
    The options that Bridge currently offers falls short in 2 area
    Load Files into Photoshop Layers-- does not import smart objects and creates a new photoshop file that ends up being as large as the largest imported file
    Place into Photoshop--only lets you do one at a time
    I need "Place into Photoshop" with multiple files
    Is there a way to do this?
    Thanks!!

    I agree, placing multiple files into your PSD as smart objects all at once like InDesign would be a great (and logical) feature for Photoshop to have. The only "workaround" I have is to create a shortcut using Ctrt+Alt+Shift+D (which is not used by anything), so you can place pictures/graphics more quickly, rather than using the menu each time.

  • Is there a way to split a very large 1 page pdf into letter size multiple page pdf?

    I often have very large single page pdfs that need to be printed onto letter size paper.  Usually I don't have access to the printer where I'm working so I have to send the file to someone for printing. 
    I have AXI pro, they don't. 
    I want to make sure the job is printed as I specify and most of the users are using Reader.  So I want to give the someone the pdf ready to print sized in legal.  This requires manipulation of the pdf that I don't seem to be able to figure out how to do.
    In older versions of Acrobat, I could print to a new pdf and designate the page size.  Acrobat would create the multipage pdf.  The newer versions don't allow this. 
    With OSX 10.8 & AXI you can't save, export, split a one page (68" x 16") document into multiple page letter size (16 pages) pdf.
    Perhaps this can be done by printing to eps and running through distiller again or something else, but I'm stumped at the moment.
    Any suggestions of how to attach this would be appreciated.
    Thanks.

    That's a tough one. Acrobat is not designed for tiling PDF files to create another PDF. That's really what you're asking. There is the option to PRINT to a PDF, and turn on the Poster feature. If were in Windows where there is a real Adobe PDF printer driver, you could probably use that feature. But for various reasons (too complicated to describe here), that was withdrawn on the Macintosh.
    If you have a copy of Adobe InDesign, and if you installed an Adobe PDF 9 PPD file (see description below), it could be done in a somewhat awkward way. InDesign allows you to place PDF files so you would need to make a page of the proper size and place your large PDF:
    Then after installing the Adobe PDF 9 PPD file, you could choose File > Print. Then choose to print a PostScript file to the Adobe PDF 9.0 PPD file. In the Setup panel, you'd choose a Letter size page. Then you'd choose the Tile option at the bottom and set the Overlap amount:
    Then you'd save the PostScript file and process through Distiller.
    My blog post below describes how to find and install the Adobe PDF 9.0 PPD file:

  • Splitting or Dividing an MP4 file into Separate Files

    I have been importing several VHS tapes with Elgato Video Capture to an external hard drive. I have several MP4 files. Some of the movie files have video from different subjects that I would like to split up. When I open them into Quicktime and copy and paste the section I want to a new Quicktime file why can I not just save the file in the format it was copied from?
    I don't want to have to import these into iMovie and re-export the video. I already have it in the format and size I want. Is there a way to just grab sections from these files and save them as is?
    I'm doing this on my MacBook not my G5 listed in my sig.

    When I open them into Quicktime and copy and paste the section I want to a new Quicktime file why can I not just save the file in the format it was copied from?
    If you are using QT 7 Pro, you can/are already doing so. However, QT Pro saves the segments in their original compression formats to an MOV file container. If your files are MPEG4/AAC or H.264/AAC you can perform the same segmentation actions using MPEG Streamclip (free) and save the files to either MOV or MP4 file containers. If you are using QT X for segmentation, then it works essentially the same as QT 7 Pro but by default writes the original data to an MOV file container without the .mov designation.
    Also when I export as it take way too long.
    The "Export" option normally re-compresses the video which is what takes so long.
    Why can't I just save and put in a name? It's already encoded and rendered.
    You can. Simply select the icon after it has been saved, click on the name to open the name editing box, and change it to whatever you want as long as the name is valid within file naming restrictions. (e.g., regarding length, characters, etc.)
    Why does it have to act like it's a brand new file?
    It is a "brand new file." Apple may have done this as part of a "do no harm" approach to prevent novice users from overwriting the original file and, thus, losing their original data for which the user may or may not have further use. As to why it doesn't offer you the opportunity to change the name, maybe you should request this option and a future enhancement. Since the name is easily changed in any case, it is not a "biggie" for me.

  • COPA - Split of Value from condition type into different value fields

    Dear All,
    Customer is having several free schemes to customer the same is set up by SD and Cost of free goods is attached to One Z condition type, this flows along with Main product as characteristic. So we have Main product cost in VPRS and Scheme cost in Z Condition and there is possibility of more than one scheme cost flowing in one Z condition for single billing document. Whereas customer request is to see the each scheme cost separately in COPA. Since Value from SD will be flowing through only one condition type , it will be difficult to me to Split this in COPA. We have given a thought of having more than one condition type from SD ( one Z condition for one scheme) but this resolve our issue at hand. If we look at long term whenever customer introduces new Scheme new condition type need to be created and related COPA changes etc, Which doesn't seem to be working out.
    Request Experts help in this, thanks in advance for the help.

    Hi Santosh
    Having a Z cond type for each scheme is preferrable.... This would address the issue with Standard SAP itself...
    Reason being, if you dont do that, then you will have to maintain a mapping somewhere in a Z Table where by system would come to know of the ratio between the schemes... This will be more cumbersome to develop and maintain... Still you wanna do that, here is the logic....
    Maintain the schemes in a Z Table... Where each scheme will have a scheme ID - The ratio applicable to various schemes and also the relevant value fields of COPA to be updated for each scheme....
    Now, add a Custom Field to the Sales Order and while creating the SO this field needs to be updated with the scheme ID(Relevant Exit to make it mandatory MV45AFZZ / ZB).... If Scheme ID is populated, your Billing should read the Split from Z Table using Exit RV60AFZZ and Update COPA using Exit COPA0002

  • Issue with file to file in PI 7.3 (Splitting huge files)

    Hi All,
    Need your help in fixing the issue with file splitting
    We are doing some sample scenarios(file to file) on PI 7.3 server.
    We are trying to split a 10MB file by using the 'Advanced Mode' option in the sender file adapter. We gave max split file size as 2MB. The file got split into 5 chunks and was successfully sent to receiver file adapter. In receiver adapter we are able to see that. But in the target folder only 1 file was seen with size 2MB. All other chunks were missing. We need to have the whole data sent from source to target.
    How to fix this issue? please provide your inputs.
    Thanks and Regards,
    Lakshmi Narayana

    PI 7.3 has capable of processing larger size files.
    Questions:
    Have you picked EOIO quality of service? Hope you dont do mapping or content conversion for this file?

  • How To Split Large Excel or CSV Files into Smaller Files

    Does anyone know how to split a large Excel or CSV file into multiple smaller files?  Or, is there an app that will work with Mac to do that?

    split [-a suffix_length] [-b byte_count[k|m]] [-l line_count] [-p pattern] [file [name]]
    is a native Terminal command. Read up more on https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/ man1/split.1.html
    I prefer to use gSplit which is gnu coreutils.
    You can install gnu coreutils using homebrew.

  • Need to split one large high-res video into sub-parts

    I have a very large high-res video (5760 x 3240) that I would like to split into 9 separate videos, each 1920 x 1080.  These would make up the content of a 3x3 video wall and would be 'stitched' back together by the media players driving the wall.
    I am new to After Effects, so sorry if this sounds like a dumb question, but I was told this was possible using AE.

    Thanks for all the responses.
    My next question was how I can make sure I am positioning the video in the composition to the exact pixel.  Seems a little inexact just dragging, but I will try the advanced sizing controls.
    I am being told that the individual media players can sync up to the ms.  We are going to test everything this week once we receive the final video. Since the entire video will be 60gb, there is the question of storage, so we are adding 64gb flash to each player.
    We are doing a similar wall in Europe and they are using a single video server along with a matrixer to get the job done.  
    I've done 2x2 walls pixel perfect and most hardware will choke on that, so I am hoping the multiple media players will be better in handling smaller chunks.
    I will let you know how it works out.

  • Split a long PDF form programmatically into smaller PDF forms

    You can programmatically split forms using LC Assembler service and use the DDX. You could extract page1 from pdf1 and create a pdf, then page2 of pdf1 into a different PDF using something similar to:
    <?xml version="1.0" encoding="UTF-8"?>
    <DDX xmlns="http://ns.adobe.com/DDX/1.0/">
    <PDF result="Final.pdf">
         <PDF source="PDF1.pdf" pages="1"/>
    </PDF>
    <PDF result="Final2.pdf">
          <PDF source="PDF1.pdf" pages="2"/>
    </PDF>
    </DDX>
    To split according to Level 1 bookmarks, you can also use the PDFFromBookmarks tag.
    For example,
    <PDFsFromBookmarks prefix="stmt">
         <PDF source="doc1.pdf"/>
    </PDFsFromBookmarks>
    More info is available in the Assembler Service and DDX Reference available at http://help.adobe.com/en_US/livecycle/10.0/ddxRef.pdf.
