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.

What is the best way to load and convert data from a flat file?

Hi,
I want to load data from a flat file, convert dates, numbers and some fields with custom logic (e.g. 0,1 into N,Y) to the correct format.
The rows where all to_number, to_date and custom conversions succeed should go into table STG_OK. If some conversion fails (due to an illegal format in the flat file), those rows (where the conversion raises some exception) should go into table STG_ERR.
What is the best and easiest way to archive this?
Thanks,
Carsten.

Hi,
thanks for your answers so far!
I gave them a thought and came up with two different alternatives:
Alternative 1
I load the data from the flat file into a staging table using sqlldr. I convert the data to the target format using sqlldr expressions.
The columns of the staging table have the target format (date, number).
The rows that cannot be loaded go into a bad file. I manually load the data from the bad file (without any conversion) into the error table.
Alternative 2
The columns of the staging table are all of type varchar2 regardless of the target format.
I define data rules for all columns that require a later conversion.
I load the data from the flat file into the staging table using external table or sqlldr without any data conversion.
The rows that cannot be loaded go automatically into the error table.
When I read the data from the staging table, I can safely convert it since it is already checked by the rules.
What I dislike in alternative 1 is that I manually have to create a second file and a second mapping (ok, I can automate this using OMB*Plus).
Further, I would prefer using expressions in the mapping for converting the data.
What I dislike in alternative 2 is that I have to create a data rule and a conversion expression and then keep the data rule and the conversion expression in sync (in case of changes of the file format).
I also would prefer to have the data in the staging table in the target format. Well, I might load it into a second staging table with columns having the target format. But that's another mapping and a lot of i/o.
As far as I know I need the data quality option for using data rules, is that true?
Is there another alternative without any of these drawbacks?
Otherwise I think I will go for alternative 1.
Thanks,
Carsten.

What is the Best way To Copy and paste data from 1 book to another

I have 18 sheets in 5 different books that I want to extract data from specific cells. What is the best way to do this? Example: 1 sheet is called Numbers E-O1 data in 13:WXYZ. The data updates and moves up 1 row every time I enter
a new number. So let's say I enter the number 12. Through a lot of calculations the output goes in 13:WXYZ. To what I call a counter which is a 4 digit number. Anyways, how can I send that 4 digit number to a totally different sheet? To bullet
what I'm talking about
data in cells Row 13:WXYZ in book called Numbers sheet E-O1
send data to book called "Vortex Numbers" Sheet E-O row 2001:CDEF
What formula or Macro can I use to make this work?
thank you!

Hello Larbec,
Syntax:
'[BookName]SheetName'!Range
Enter in cell 2001:CDEF:
='[Numbers]E-O1'!13:WXYZ
This assumes that the file is open in Excel. Otherwise you need to add the path:
'ThePath[BookName]SheetName'!Range

What is the best workflow for AVCHD and iMovie/iDVD 09?

I am recording AVCHD video with a Sony HDR-SR11. I don't have a blu-ray burner yet, so I want to create the highest quality DVD's I can from this source video using my MacBook and the software I have (iMovie 09 and iDVD 09).
Currently I am importing the video clips into iMovie 09 at the 1920x1200 setting. After creating a 16:9 movie I choose "Share to Media Browser" and export at the highest setting I see (I think 1280x720, I'm not on the MacBook at the moment).
After a long while this completes and I launch iDVD 09. I drag the movie I exported above into the theme and burn at Professional Quality. After another long wait I have my DVD but I'm quite disappointed with the video quality.
Even taking into account that DVD is not a hi-def disc format it seems like the video quality should be better. Is there a better workflow I should be using with this combination of software? Maybe some way to avoid scaling/compressing the video twice? Or is this as good as it gets with iMovie 09 and iDVD 09? I may have access to iMovie 06, if that would help.
Thanks,
Gerald

Why jpeg file exported from Aperture with 300 dpi's it opens with 72 dpi's on PS ( image size)? I've tried several combinations and all give different results. And I am confused on what is the best workflow for me.

Ok.
My workflow is
RAW > Aperture Library > export jpeg high resolution 300 dpi's > one file on PS > edit > Save us jpeg. The I realised that files from PS were being save in a smaller size from the ones exported form Aperture. That is when I went o see <image size> on PS and files were with 72.
Since ten I've trying different things
1. Aperture > export as PSD > open on PS > edit > Save us jpeg = small file (around 15 MB)
2. Aperture > export as jpeg high resolution 300 dpi's > open on PS > CHANGE dpi's to 300 on <image size> edit > Save us jpeg = big file (Huge, actually)
What am I doing wrong? Would someone give me guidance and tell me what is the best workflow, considering I edit photos to deliver to my clients and I shall give them 300 dpi's.
Thank you

What is the best combination of read and write objects to binary files ...

Hi everyone,
what are the best combination of read and write objects to read/write a record of customers from a binary file. I should be able to use StringTokenizer. I am bit confused with all these Stream reader and writers.
abdul

You are, indeed, confused:
o StreamTokenizer works on character input, not binary input.
o Readers and Writers in general work on character streams, not binary.
That leaves you various input streams and output streams for reading binary data.

What is the best way to store and search 2D data

Hi,
There is a set of data (~10k records ) in 2D dimension.
like this :
Col 1, Col 2, Col3....
What is the best way to store and search those records ?
Thanks in advance
Wilson

Hi,
Either userObjet[][] if you know how much data you have, and the data size is fixed, or use a list of lists. E.g. A Vector of Vectors (some will probably say that you should use an ArrayList instead, and that could be the case, but it sounds like you would want to display the data later on, and a DefaultTableModel (for JTables) uses a Vector as data holder).

What is the best way to scan and sort old photos in iPhoto

What is the best way to scan and sort old photos in iPhoto? They do not have digital dates.

Hey Chicago Sue,
Once you scan them and have them on your desktop. You should use Automator and assign the common IPTC tags to the images, so that when you do import them into iPhoto, they get recorded.
Here is an example of an action in Automator:

I just bought a new PC and now have ample space on my C drive to house my music Library which is currenlty installed on a external drive. What is the best way to install and move the itunes library to my C Drive?

If the entire library is on the external drive then simply copy the iTunes folder into <User's Music> on the new computer, then install iTunes. If you've already installed iTunes you will want to remove the empty iTunes folder in <User's Music> first.
If it turns out you only have the media folder on the external drive then take a look at this post...

What is the best way to secure and harden a Macbook Pro against unwanted surveillance?

What is the best way to secure and harden a Macbook Pro against unwanted surveillance? Tor, VPN, Little Snitch, etc. This would be for that latest version of Mavericks.

Governments and ex's will/may have recourse to the legal process (or in the case of the Gov they can choose to ignore the legal system if they feel like it) when they want to see something of yours, good luck hardening your Mac against that. The best way to avoid the possibility of snooping over public networks is to avoid them but if you can't then Kappy's suggestion will help.
Strong passwords (everywhere) and don't use the same password in multiple locations.
If you really want to secure your home wireless use Mac address connection authentication, do not allow unknown Mac addresses to connect. It's much stronger than a WPA password alone.

What are the integration points with sd and qm

hi,
sap gurus,
good morning to all,
what are the integration points with SD and QM.
in r/3.
regards,
balaji.t

Dear balaji
Before doing PGI, there will be a preinspection stage where SD will have to integrate with QM. Similarly after sales, whenever there is sales returns, QM will come into picture.
To control the above scenarios, in material master, go to "Quality management" view and click on "Insp.setup" where you need to assign Inspection Types like 04, 06 etc.

What is the best way with c or cgi?

Hi,
what is the best way with C or CGI(with binary file)
1. simple data transfer, from C or CGI application(without binary file) to XI for realtime sync?
2. attached binary file transfer, from C or CGI appliction to XI
for realtime sync?
thanks
venjamin.

Hi venjamin,
which adapter do you want to use? What kind of data do you want to send?
I guess, if you only want to create a sync scenario with a application written in C or CGI, a soap webservice or a call of the http plain adapter would be the best way.
Regards
Philipp
