Data Adapters used for digital warehouse

Dear All,
I need some information on how to load , store, extract, transform digital data in oracle database.
Are there any off the shelf data adapters from oracle which can be installed /configured to deal with digital data.?
Or is it required to write any custom code using either .NET, C Sharp of Jave for the same.
We want to build a datawarehouse for a multimedia company which would like to store its digital data in warehouse and need informaiton on adapters available in the markt to deal with such data as explained..
Thanks and Regareds

The resolution of 0.1 Hz does require a 10 seconds long acquisition, but instead of running only one sine tone at a time you may consider generating and acquiring multiple tones (eventually all 1000) at once.
This techique of multi-tone excitation / acquisition is very efficient but has some drawbacks.
1 - You system under test has to 'work' under such an excitation signal. This is not always the case.
2 - What you gain in measurement speed, you partially loose in dynamic range. The more tones you use for a measurement the more you 'loose' dynamic since given a total signal range, each tone will have to have a reduced amplitude in order to not overload your system.
3 - The technique requires an Arbitrary Waveform Generator and I don't know if that i
s what you are using.
The setup is a little tricky because the tones have to be an exact multiple of the 0.1 Hz and your acquisition length and sample clock need to be perfectly locked to the generation to avoid frequency domain leakage between the different signals.
On the measurement side use either the Power Spectrum (signel channel) or the Frequency Response (dual channel measurement) but do NOT use a window (= none or = rectangular)
LabVIEW has all the tools needed to help you build that measurement. Check out the Basic Multitone.vi in your Analyze>>Waveform Generation palette.
If everything works for you, you may be able to reduce your measurement time from hours to less than a minute (possibly all the way down to 10 sec. !)

What data is used for the link title in osssearchresults.aspx

In our OOTB SharePoint installation we have a search results page in a collaboration site that displays Word documents. Each word document has a Title property, however the text used for the hyperlink to the document in the search results page does not seem
to use the Title property, instead it uses some text from inside the document, e.g. the contents of the first H1 tag.
I had a look at the XSL of osssearchresult.aspx core results web part, and this uses a "title" parameter. So I can only assume that when SharePoint search catalogues a Word document, it decides to ignore the title property of the list item
and instead derives the title text from content within the document itself.
Is that correct? Or am I missing something? Can I change the title for Word documents in search to be the actual title of the list item?

Hi,
The word documents have two columns “Name” and “Title” by default. The “Name” column is the file name and is “file” column type, its related Crawled Property is ows_LinkFilename
. The “Title” column is the document title and is “Single line of text” column type, its related Crawled Property is ows_Title . When SharePoint Search crawls the word document, both the two columns are crawled. However, the ows_Title
crawled property is mapping to “Title” managed property, but the ows_LinkFilename crawled property does not map to any managed property. In the SharePoint search results, the word document shows its “Title” managed property.
So for your scenario, the search result should show the “Title” column value. Please go to your document library and verify the “Title” column’s value of your word documents.
For more information, you can refer to the thread:
https://social.technet.microsoft.com/Forums/sharepoint/en-US/4e1749cd-cf4d-46d6-98e2-3f42366e376e/how-does-the-search-result-are-displayed?forum=sharepointadminprevious

In Aperture 3.4 Export Slideshow to a video, what are the actual Data Rates used for "Best", "High", ... "Least" quality for a given resolution?

My Photo website host (SmugMug) converts uploaded video files at a specific Data Rate in Mbps before installing them. I would like to compress my slideshow video file to the same rate before I upload it to reduce file size and upload time. When I choose the "Custom" setting for an Export, I can choose 1 of the 5 Quality choices and see the estimated file size. But, I cannot know what the actual Data Rate is until after I wait a long time to export the slideshow (hours for a long slideshow) and then examine the resulting file in QuickTime Player's Inspector.

I ran a few tests using a short slideshow (16 images, 1:23 mins/secs) at 1,728 x 1,080 resolution to find out the bit rates for various quality level choices.
Export setting              Quality          Resulting bit rate          File Size
HD 1080p                    default                20.68 Mbps              214.8 MBytes
Custom                       Best                   20.49                       212.8
Custom                       High                     6.25                         65.0
Custom                       Medium                3.97                         41.3
However, I don't know if those bit rates will be the same for different length slideshows or for different output resolutions. My SmugMug host site uses an 8.0 Mbps rate for a 1728 x 1080 video file. If I choose Custom/Best, my file will be almost 3 times bigger and much higher quality than necessary, but if I choose Custom/High, my file will be smaller and lower quality than SmugMug's converted version.
I have installed MPEG StreamClip that will let me convert an exported Aperture slideshow video file, and StreamClip allows me to choose a specific bit rate in Mbps. But, I would prefer not having to do a 2 step process (Export from Aperture, then convert in StreamClip).

Formatting tags in xml data set used for spry region

I am trying to put ,,, tags in my xml data set but they cause the field to not load. For example I would like to create an xml file as follows:
<blog>
 <blogentry>
 <blogdate>Jan 2009</blogdate>
 <blogtitle>January Blog</blogtitle>
 <blogtext> this is a paragraph
and so is this
 </blogtext>
 </blogentry>
</blog>
When I do this I don't get anything in the spry region. If I remove the , tabs it works.
Is there anyway to do this (not just with but with any tags ... ie. tables, etc.).
Thanks/Hal

I have an online example:
http://www.pearlmanpr.com/perspective_test.html
The spBlog.xml file contains test junk. If I put the <[[CDATA....]]> inside the BlogEntry/BlogText tag it doesn't work at all.
http://www.pearlmanpr.com/perspective_test_2.html
If I use it without the <[[CDATA..]] it doesnt work either.
http://www.pearlmanpr.com/perspective_test_3.html
If I use it without any <> within the tag it sort of works (still needs to be aligned).

What data sources use for report which looks like tr. FS10N

Hello,
I would like to create report in BW which will looks like transaction FS10N (G/L account balance display). Can anybody give some tips which data sources I should use and how initialize these data sources?
There is old genereal ledger in our system, so I suppose that I need data sources 0FI_GL_20 and 0FI_GL_21 but I don´t know how initialize it.
Thanks for help.
Regards,
Karel

Hi Suman,
I asked because f.e. retail data sources 2LIS_03_BF or 2LIS_03_UM had to be initialize via tr. OLI1BW and OLIZBW. After that data sources were filled and then data could be loaded to BW by infopackages. But thanks for info that some data sources needn't initialization. By the way, is somewhere info about this (if data source need initialization and how find out transaction for initialization)? Thanks for advices.
About data sources 0FI_GL_20 and 0FI_GL_21: We delayed this because there is needed to switch on function Reporting financials (tr. SFW5) and other things -> I didn't recieve confirming (from higher position) that I can switch it on

'Date created' instead of EXIF date getting used for batch naming/folders?

I've noticed that Aperture is using the file creation date as opposed to EXIF date/time info when it imports my photos. Camera is a Nikon D200. Images are .NEF files.
If I allow Aperture to apply new master file names, based on Image Date - Image Time, it uses the Mac's file creation date (whenever the file was copied to the machine) as opposed to using the EXIF date and time.
I've already filed a bug with apple, but wanted to put it up here as well to see if others were having the same experiences.

Hello,
I use exiftool to modify the Creation and Modification time of the files. After that I use LR "Ajust time" feature to set the time of the movies in LR to the file creation time (last point). This works fine for me.
For MOV (Quicktime):
exiftool "-FileModifyDate<TrackCreateDate" "-FileCreateDate<TrackCreateDate"
For AVI:
exiftool "-FileModifyDate<DateTimeOriginal" "-FileCreateDate<DateTimeOriginal" *.avi
Depnding on your camera (and container format mov, avi) you may also ajust the time zone, e.g.
exiftool -FileModifyDate+=1 -FileCreateDate+=1 -if "$CameraModelName =~ /EOS 600D/i" *.mov
Which time in the container (MOV, AVI) you use as source, depends on your workflow. I edit my mov files before import. Therfore "CreateDate" is the time when I edited the file. Quicktime and (some) avi file contain a time when the containing stream was created. I use this vaule as source.
exiftool <filename> gives you detailed information about all available times.

What computer to use for digital workflow?

I have an old but faithful 2003 Powerbook G4 15" 1.25 GHz with 2GB ram. But as I grow in my digitial phography work I can see that I need to get a new computer. I have looked at the iMac but 2 BIG problems.
1) They only offer a glossy screen and every photo forum, blog etc by any professional or semi pro person, all say do not use a gloss screen but the matte version. The Apple store sales people3 pooh poohed that but I hate gloss screens anyway. Plus I have heard they are very difficult to calibrate.
2) The iMac (What I was primarily considering) seems to have severe issues. I was just on the discussion forum here and the stripes on the display and the logic board problems on 2 year old iMacs greatly concerns me. Apple quality seems to have slipped and their sales staff seems to do nothing but pooh pooh issues.
So for you using Aperture, what would you do? The MacPro is too expensive, the mini-Mac is not able to to the job (maybe) and the iMac quality scares me.

Just my 2¢ and a bit of professional experience.
First off - there is no issue in calibrating glossy displays.
Second - I have come to the conclusion along with a number of colleagues that it is a matter of personal preference rather than a purely technical evaluation as to the "best" surface treatment of a monitor that is suitable to evaluate images on-screen. I have also come to the conclusion that personal preference has a lot to do with what you may be used to using seeing.
Third - Making decisions based on internet or other hearsay and urban myth is not a great way to do things. I find 90+% of "facts" espoused regarding digital photography and photography in general are anecdotal at best and generally obsolete.
I am a color nut - always have been and I have made both good and bad purchasing decisions - most of the good ones have been based on what my eyes see and what I have learned through my own use and experience. The worst ones were based on research and what other anonymous people's general opinions were (mostly based on echoing others unsubstantiated bullcrap)
I happen to own a fairly wide array of gear and can tell you that after becoming used to a few of my glossy displays in a number of formats and sizes the matte surface coating actually bothers the crap out of me when critically evaluating images on screen for a number of reasons. I have a couple of monitors that have better color gamut than my Apple cinema 24" displays but actually use the new Cinema 24" displays most of the time at this point and do not end up making bad color decisions.
Last but not least what is your primary output medium for your photographs? The web - who cares what you use it will look different to almost everyone out there. Your TV? - Please give me a break. Walmart, Costco? - Again your monitor will be the least of your worries. Highest quality in-house or professional color managed printing with a RIP and custom profiles for every paper, ink set, viewing conditions, etc? Your experience in translating tones from additive to subtractive reflected light media are probably more important than your monitor.
Bottom line - buy the 24" imac and be very very happy. If you want a laptop buy the 15 or 17 macbook pro with a 24" cinema display external keyboard and mouse and be ecstatic.

Data used for a 25 minute skype call

Hello,
I am using skype 7.0 for windows PC to make 25 minute skype calls for work. I am just on an 800mb limit per day. According to my ISP's Web site, 800 mb is enough to make 4.5 hours of skype calls. But I saw that for just one skype call, my statistics tab showed I consumed about 350+mb already after just one 25 minute skype call. So if this is the case for every skype call I make, I can only make 2-3 25 minute skype calls before my ISP limits my internet usage for the day.
How much data is used for 1 25 minute skype call using PC ?
I think my ISP's Web site is misleading about skype calls.
Solved!
Go to Solution.

You can still have your video on and your student can have their video off. If they "call" you instead of "video call" you, their video will never be engaged and you can just turn your video on from that point. The big problem with ISP bandwidth restrictions is that their limitation tends to count upload and download which greatly reduces your overall real bandwidth. You can use this as a guide as well to guesstimate.
http://community.skype.com/t5/Windows-archive/Bandwidth-Consumption-Question-Again/m-p/2887243/highl...
Be aware that this only accounts for one-way communication. If you were to both have your video on at the same quality the figure would double. If your student only has audio engaged then you would only add 25 minutes of "äudio" to gauge an approximation. Since Skype is "automatic" call quality can go up or down. Netlimeter or it's equivalent is the only real way to lower the video quality other than using a much lower resolution camera.
In regards to your ISP's "video conferencing" calculation, it's not pulled out of a hat. It appears to be calculated off a total video conferencing rate of 384k which is generally at a CIF/SIF resolution (~352x288 or lower). Skype's video quality operates at a higher rate that even supersedes their 90-minute movie estimate they provided as well. If you were to compare either a 90-minute DVD quality video or a 90-minute Blu-ray quality video the bandwidth would of course be surpassed as well as downloaded/watched movies vary in quality as well.
I believe the average amount of bandwidth consumption for typical households can be upwards of 150-300+ Gigabytes a month. Low metered accounts are generally for mobile devices or people who don't plan to use the Internet beyond basic web searching and e-mail. I personally would use a plan like that to get Internet in remote places but I wouldn't plan to do anything beyond the basics.
In regards to overage of bandwidth consumption ISPs either:
1. Terminate the data service for the month when exceeded
2. Charge you overage charges at a set cost per MB or GB.
3. Allow you to continue to use the service but cap your Internet speed to twice that of dial-up (115kbp/s) or possibly even lower.

Using a digital signature in 7.0 after it is created

I created a digital signature in Acrobat 7.0. I'll use it once to sign a document. When I create a new document and try to sign it, it says my password is incorrect. I know it is not incorrect as I had only created it barely 5 minutes before. And I wrote it down! What is going on? Do I need to recreate a new digital signature for every document I sign? I'm not using third party verification.
Thank you in advance for your thoughts and advice.

Most third party signature pads require two things.
1. An Acrobat plug-in
2. A device driver to connect the plug-in to device data being used for the signture.
Which third party Signature Pad are you using and which software are you using in conjunction with the Signature Pad.

Using a digital signature-base method to get tcUtilityFactory

In OIM API usage guide it is sais that:
"The entity using the APIs must maintain security of the private key for the signature. The private key is the basis for establishing trust between the two systems.
Oracle Identity Manager must also know what certificates to trust. To trust a certificate, the signer of the certificate must be added as a trusted CA in .xlkeystore or in the keystore configured in the security section in the xlconfig.xml file on the server.
So, if I want to obtain a copy of certificate for calling OIM API purposes, for which user I must create a certificate request? Or should it be the server certificate, issued for server OIM is running at?

IPad Verizon data plan used up?

After using a new iPad mini on a Verizon data plan for 3 weeks, only 50 MB had been used. Then the device suddenly indicated that all data was used for the month, and refused to connect. A few hours after this, it "fixed itself", connecting, and showing that only 50 MB had been used for the month.
Is this a common occurrence?

I've never seen this happen on my Verizon iPad. I've been using it since July 2011 on my account.
ID suggest watching your usage though to see if it happens again. If it does I'd contact Verizon.

Data Access Object for Data Warehouse?

Hi,
Does anyone know how the DAO pattern looks like when it is used for a data warehouse rather than a normal transactional database?
Normally we have something like CustomerDAO or ProductDAO in the DAO pattern, but for data warehouse applications, JOINs are used and multiple tables are queried, for example, a query may contains data from the Customer, Product and Time table, what should the DAO class be named? CustomerProductTimeDAO?? Any difference in other parts of the pattern?
Thanks in advance.
SK

In my opinion, there are no differences in the Data Access Object design pattern which have any thing to do with any characteristic of its implementation or the storage format of the data the pattern is designed to function with.
The core pupose of the DAO design pattern is to encapsulate data access code and separate it from the business logic code of the application. A DAO implementation might vary from application to application. The design pattern does not specify any implementation details. A DAO implementation can be applied to group of XML data files, an Excel-based CSV file, a relational database, or an OS file system. The design is the same for all these, it is the implementation that varies.
The core difference between an operational database and a strategic data warehouse is the purpose of why and how the data is used. It is not so much a technical difference. The relational design may vary however, there may be more tables amd ternary relationships in a data warehouse to support more fine-tuned queries; there may be less tables in a operational database to support insert/add efficiencies.
The DAO implementation for a data warehouse would be based on the model of the databases. However the tables are set up, that is how the DAO is coded.

Whether PXI can be used for Event data logging in an electrical Substation ?

Whether the NI PXI system can be used for recording digital event data with 1 ms accuracy ?Whether its DI boards support onboard timestamping ? Whether PXI can be synchronized with time pulses from a GPS receiver ?

Yes indeed, there is a digital event recorder example in developer zone, search for "digital time interval" on NI developer zone, or follow this link: http://sine.ni.com/apps/we/niepd_web_display.DISPLAY_EPD4?p_guid=B45EACE3DCA356A4E034080020E74861&p_node=DZ52336&p_submitted=N&p_rank=&p_answer=&p_source=External
In addition, we have done additional work to create a template for the LabVIEW FPGA, http://sine.ni.com/apps/we/nioc.vp?cid=11829〈=US
which has 96 digital I/O lines as well as 8 analog in. With the NI-7831R you are able to combine analog and digital events in the electrical substation.
Further, using PXI, we can synchronize with a GPS time stamp such as IRIG-B, and perform these functions all in a headless - real-time OS LabVIEW.
I woul
d be happy to discuss your application in more detail and offer a complete solution, or a recipe to create the solution yourself.
