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.

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.

    Why do you need a expensive MacBook Pro?
    Your attending high school and unless everyone else is rich also your likely going to be a target by the more poorer students for theft or damage to the machine.
    You could keep it home, but if you need it for class then your exposed again.
    Also at that age your not very careful yet, a MacBook Pro is a expensive and easily damaged machine.
    Unless your made of money and so are others at your school, I would recommned a low profile, just does the job cheap Windows PC.
    If it dies, gets lost, stolen or damaged because of your inexperince handling senstivie electronics then it's no big deal.
    You can buy a Mac later on when your sure you have a need for it, currently there isn't much advantage of owning a Mac compared to a PC, they do just about the same things now, one just looks prettier than the other.
    Since 95% of the world uses Windows PC's your going to have to install Windows on the Mac in order to keep your skills up there or be unemployed, so it's a extra headache and expense.
    good luck

    they are not comments that have a clue whats up in pro work...sorry..but is fact.
    the DIT station ( live during shots ) could mix the background and live shots live...so you 'see' on monitor what you get at end of edit and keying.
    trust me, this is very advanced.
    dont worry about the small stuff.. just test and shoot and test and shoot and get what you need.. live ..no post work is good work.
    dont know how else to say this.. guess you had to be there.
    try to imagine live and keyed at same time...melt the pictures in link you see in your head...original with screen, end result with key...is fun

    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'm pretty sure battery capacity doesn't related with power performance of your system.. (in a notebook)
    well perhaps this is just another way of people to advertise their website.
    anyway. go for the biggest capacity, make sure it's genuine, and you can unplug ur battery if you dont  have one

    I will use Barclays Card for 18 month free interest.
    I wil ask Apple clerk to avoid LG monitor.
    I will buy those in Apple store.
    Which one will you recommend?

    Tha's something you need to decide for yourself.
    Do you think you need 16GB of memory or 8 will be enough?
    Do you need to carry your macbook around with you more often? if so just get the 13" it's easier to carry.
    Or maybe you enjoy watching media on a bigger screen?
    As for word processing it shouldn't be a problem on both notebooks.
    Also can you afford buying the 15"?
    And what about the hard drive capacity?
    So my advice is to consider these aspects, make a list of pros and cons and see what you come up with

    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.

    IOS4.1,4.33,5.01,5.1，which one is better for 3GS?

    The 4.1 version for 3 gs is the best one .
    as far  as 5.1 its considerably slows the 3gs and 4.3.3 has known issues like  wifi signal dropping and battery drain. so you must stay on  ios 4.1 for your 3gs.

  • Which course is better for consolidation apects of BPC and other EPM tools

    Hi All,
    I am having the technical understanding of BPC as a tool, but I am not able to understand the consolidation part of it. I would like to gain an insight of the financial part of the BPC consolidation. Not only this, there are few other tools in EPM suite (like Intercompany reconciliation; Financial consolidation; Disclosure management; Financial information management) which requires relevant understanding of Financial accounting.
    Can anyone please suggest, which Professional course would be better for the above tools; not just from the point of knowledge but also with regards to job prospects (as I have seen that company's now asking for consultants with background of CA/CPA/ICWA etc).
    I had gone through the course structure of ICWAI, but not sure whether it will be of very help.
    Please suggest.

    Hi Sonti,
    I understand your point, but as you might be knowing that in real world no one just decides by looking at the face that this guy is having good finanicial knowledege, so lets take him for the job. Moreover when it comes to client interaction, if the client is given two profiles - where one consulant writes only his experience and knowledge and the other one describes his/her added certification or post graduation in the concerned subject (in addition to the same level of experience and knowledge), then ofcourse the second one will be given the priority over the first.
    So my view is that just by understanding the topics will never give you the cutting edge in the market, you additionally need some thing to make your profile an eye catcher and that too needs to be relevant with your area of work.
    Thats where I am confused and hence posted the question.
    Also many thanks for the book that you have suggested, that might be a good option for the time being.
