Personally I use brain, pen and paper for designing/modelling - then simply write scripts to create those tables.Me too.
But of course I realize that is not the way of a modern programmer :-)No, modern programmers rely less on the brain part.
I have heard other people saying that the (now free) [url http://www.oracle.com/technetwork/developer-tools/datamodeler/overview/index.html]SQL Developer Data Modeler is helpful for modelling. I haven't any personal experience, though.
I have used it to reverse engineer the design resulting from the brain / pen / paper / scripts process and produce pretty pictures for the modern programmers to try and understand. It works quite well for this.

    I am using ERwin® Data Modeler r7.1 (7.1.1.1207). It supports most new features of Oracle 10g such as hash, list, composite hash, setting LOB storage properties etc.
    We just upgraded from version 4 recently. In the old version, I had to manually modify the generated scripts.
    ERWin r7 supports all Oracle 10g (Release 2) new features we need for our projects. It offers far more functionality and options than the old version. It supports all partition types in Oracle 10g: Range, Hash, List, Composite-Hash and Composite-LIST and offers more storage settings.
    Another nice new feature of ERWin r7 is that it offers purge option in the DROP TABLE statement. In Oracle 10g, the recycle bin contains all the dropped database objects until you permanently drop them with the PURGE option. Otherwise, you will see many funny looking objects like this: 'BIN$0+ktoVChEmXgNAAADiUEHQ==$0'.
    With the purge option, you don't need to purge the recycle bin after the forward engineering.
    SQL> purge recyclebin;
    My favorite is Oracle Designer.

  • Which tool to use for desktop database app (.exe), flash or flex?

    I have spend some time trying to compare the tools, but still something not clear.
    The final app should be an .EXE file. There's no web access needed, only local data base access.
    What I currently know is that flash cs5 allows to export a projector file (.exe), but not sure about it has database access, and for flex desktop application, it all AIR based so final file is not .exe.
    Thanks!

    Your question is not very clear... if  I look at the header of your request you are asking for database tool? if thats the case their are a ton of them sql developer, toad, etc... if you are looking for an exe file out of flex your sadly mistaken. flex produces a swf file html file and a couple of other java files... then you slap those on the server and browse to the html page.
    hope that helps.

  • Which tools to use for implementing an e-learning course?

    Hi,
    I was asked to develop an e-learning course. The course is ready and involves some power-points slides and perhaps some movies.
    What do you advise me to use? I have to develop a platform where you log on, follow the course and finally answer some questions in order to get a certificate.
    Consider that in Oracle I've always used only SQL Developer, APEX and a little of Forms. What of these of other oracle tools you would use for such an application?
    Thanks in advance!

    What this has to do with the current forum ?
    For the answer, Oracle's own Learning Library is using APEX to give a front end for organizing and searching such kind of recorded self learning tutorials. So it should be a good option to consider. Rest depends on what you know in a real good manner! Whatever it is, APEX, Forms, you can (and should) use that.

  • SQL Developer can be used for database design

    can I use SQL Developer to design the database?

    It really depends on what you mean by "can," how complex the schema design is going to be, and your comfort level.
    AB is quite right to point out Oracle Designer-- that's a very powerful, very visual tool for creating physical and logical schema designs. It also has a relatively steep learning curve and a relatively large installation footprint. If you need to generate highly complex schema designs, to allow multiple modelers to work together, and you will use the tool frequently enough to justify the training time, Designer is a wonderful tool.
    On the other end of the spectrum, however, it's perfectly possible to generate a schema design using SQL*Plus or SQL Developer with a white board or scratch paper nearby to help think through various issues. The tools aren't presenting you with pretty ERDs, they're not automatically translating visual representations of designs to physical implementations, etc. but it's quite possible for a human using those tools to do the translation.
    Either way will work-- the constraints of your particular project and your comfort level with various risks will determine which approach is more appropriate.

  • Which tool is used for Oracle 11g performance tuning?

    Hi all
    I used statspack for 9i's performance tuning.
    But with 11g R2 now I want to know which way are you using to do performance tuning?
    Statspack? OSW? RDA? ADDM? Or other ways?
    Thank you.

    Someday - and no one knows when that day will come - maybe all applications will be able to take advantage of the Retina display. But for the present, not many do: including all Adobe applications. There was a demo of Photoshop at the Apple World Wide Developers Conference of Photoshop running at native Retina resolutions but no one at Adobe in marketing is saying when, if or how the upgrade may be coming. It could be a week, it could be a year, it could be 2-3 years. No one knows. And only Apple app's (for the main part) are really utilizing the native Retina display.
    I've seen some demos of some applications (Apple's) that take advantage of the Retina display and they're awesome. But in actually working in the here-and-now I've heard quite a few gripes, particularly on the Photoshop forum, of menus looking pixelated and/or 'blurry' so I'm not quite ready to jump into the Retina display boat just now. Don't get me wrong - others have ad are very, very pleased with their selection. But until Retina displays are available on larger monitors, the maximum work area that you're going to be able to use is 15" - and that's simply not enough room for full-blown graphic design. Then there's the cost factor - for the $4,000+ you spend for a completely full-blown Retina kit, you can get a standard MacBook Pro, 16 GB of RAM, a fast SSD and even the Apple Thunderbolt Display for the same amount.
    The standard MacBook Pro isn't better than the Retina display: it's just different. And I think (and this is only my opinion - other graphic designers should feel free to jump in here) that it's the best computer that you can get for your specific purposes. And, towards that goal, I have to recommend a very good external monitor (there's nothing more annoying than having to use InDesign in a single-page mode rather than side-by-side because your monitor isn't big enough).
    Remember that this is only my opinion and that others might jump in with their own. But I was in the electronic pre-press business for more years than I care to admit and we always - always - worked with at least 19" monitors (and that's back when dinosaurs actually ruled the world).
    I hope that others will jump in with their comments. I'm going to follow this thread and see!
    Good luck,
    Clinton

  • Which tool is better for ETL?

    I want to transfer data from RLDB to Essbase, there are many method and tools, I don't know which tool is better for my case. Now, what I am doing now is:
    1. Create views in Oracle
    2. Export view to falt file
    3. Import flat file to Essbase using rule file and MaxL import script.
    4.The data size: flat file rows 3-4 million, time used: 13 hours
    I want to use more powerful ETL tools, such as: Informatica PowerCenter, OBIEE, FDM, EIS, ..., I have basic knowledge for the above tools, but don't know which tool is better for my case? Please advise?

    First to streamline your existing process, you could get rid of step 2 and add a odbc connection to the server and Sql statement to the load rule to pull directly from your Oracle database. Of course with the number of rows you have, if you use the same extract multiple times, I would create a table to load into from the view and pull from that table.
    As for using an etl (Elt) tool, Informatica is pretty powerful and there is a version of it (although not supported in the future called DIM). I might go the ELT route with ODI(Oracle Data Integrator). In the future I might use OBIEE, but I don't think it fully ready for Essbase until the next version and I don't think it will rank on the same level as a full ETL tool for conversions.
    Edited by: GlennS_2 on Jan 2, 2010 9:58 AM
    As for EIS, I would not use it, but might use Essbase Studio. (It can use OBIEE as a source) again this is not an etl tool, it would just take youe existing views and load them.

  • Which CKM is used for moving data from Oracle to delimited file ?

    Hi All
    Please let me know Which CKM is used for moving data from Oracle to delimited file ?
    Also is there need of defining each columns before hand in target datastore. Cant ODI take it from the oracle table itself ?

    Addy,
    A CKM is a Check KM which is used to validate data and log errors. It is not going to assist you in data movement. You will need an LKM SQL to File append as answered in another thread.
    Assuming that you have a one to one mapping, to make things simpler you can duplicate the Oracle based model and create a file based model. This will take all the column definitions from the Oracle based model.
    Alternatively, you can also use an ODI tool odiSQLUnload to dump the data to a file

  • Hello, can you say to me which tool to use to correct a sound track saturated in audition.

    Hello,
    Can you tell me which tool to use to correct a soundtrack saturated in audition.
    thank's

    Hi
    With regard to your question, is this an over-recorded audio track that you wish to recover?
    You don't give me much to go on, but try this
    If it is a single over-modulated track, open it in Edit View, Select all, then
    go into edit menu and select convert sample type and select mono or  stereo whichever applies,
    then select the bit depth of 32, and make sure the sample rate is correct for the file, e.g. 44.1 etc
    then select OK
    Depending on file size it may take a minute or two, but when done, Select the full file by double
    clicking on the waveform and then go into effects "Amplitude and Compression" and select
    normalise and select show in dB's, Then "Normalise to" and enter - 3dB this means minus
    The ensure that the other options are ticked e.g Normalise all channels equally, if it is a stereo
    file, and click and select "DC" bias adjust to 0.00%
    This should reduce the level, check is sounds ok, and if you are satisfied with it convert the sample
    type back to the bit depth and sample rate of the original recording.
    If you are not happy with the result, if was very badly distorted, try a lower normalise value of -6dB
    Hope this helps, if I haven't understood your problem please add more details
    Cheers

  • Which ports oracle use for replication..

    Hi All,
    I want to know which ports orcale use for replication.plz reply me quickly.
    Thanx in advance

    This is configurable. By default, listeners will run on port 1521, but sites can specify multiple and/or different ports. Depending on the OS of the database, connections made on that initial port may be redirected to a different port (Windows) or may do all the communication on the listener port (Unix). Windows databases can be configured to do all communication on the listener port, though there may be a performance impact to doing so.

  • Which method is used for event creation

    Dear All,
    My client has more then one Purchase Organization. Workflow for Purchase order release very from pur org to pur org. For example - workflow WS92000030 is trigger when PO is created for India pur org where as workflow WS92000021 is trigger when PO is created for US pur org.  
    I checked and found that same Object Type - BUS2012 & event - RELEASESTEPCREATED is used in all Pur. Org PO release workflow. Also I found in Transaction code - SWETYP that Type linkage activate for  BUS2012, RELEASESTEPCREATED in all the PO workflow - WS92000030 & WS92000021.
    As per my knowledge, event can be created in various way such as Function module, Change document, General status management, Business Transaction Events etc.
    Can some one guide me, how can I found that which method is used for event creation in different pur org?
    How can I fould what is the fuctional module used for event creation if Fuctional module used for event creation. 
    For your information, I can see in T. Code - SWUO that 'Result dependent on a check function module'  for all the workflow - WS92000030, WS92000021 etc.
    Thanks in

    Hi Sahu,
    I dont think they have used the Function module or change document or any other kind of methods to trigger the workflow. This is because RELEASESTEPCREATED method is a standard method and it will be triggered by standard SAP. They can not make changes in standard sap saying RELEASESTEPCREATED should be triggered for this Purchase Org .
    Istead what i think is, they might have given the Event Condition for each workflow.
    In SWDD>> basic settings>> Start Events, we can give condition on triggering the workflow.
    Please check this.
    Regards,
    Gautham

  • How to specify which cert to use for software virt server?

    Is there a way to specify which certificate to use for each software virtual server? So, for example a user hitting https://somewhere.com would get the certificate for somewhere.com while the virtual server https://somewhereelse.com would use the certifcate with the name somewhereelse.com in it?

    No, this is not possible due to limitations of the underlying protocols.
    HTTP requests are sent over TCP connections which deal with IP addresses and port numbers (i.e. hardware virtual server properties), not hostnames (i.e. software virtual server properties). The HTTP protocol adds software virtual server support by allowing a client to identify the hostname (e.g. "www.iplanet.com") of the server it wishes to communicate with. This is achieved by including a "Host:" header with each HTTP request.
    Unfortunately, the SSL/TLS protocols require that the web server present its SSL/TLS certificate BEFORE the client sends its HTTP request. Since the software virtual server information is contained in the HTTP request, it is not possible for the server to select different certificates for different software virtual servers.
    You will need to use hardware virtual servers (i.e. virtual servers that have different IP addresses and/or port numbers) if you wish to use distinct SSL/TLS certificates.
