Need Schemas or Databse model for practice

Hi,
Is there any freely available Schemas which I can copy or transfer to my oracle server for practicing SQL & PL/SQL?
Please let me know how should I work on creating a database model.
Thanks,
Trips

You will find the scott schema in %ORACLE_HOME%\sqlplus\demo\demobld.sql
The HR schema, which tends to be the one used in the documentation samples, will be in the %ORACLE_HOME%\demo\schema\human_resources directory. You will find several other sample schemas in the parent directory.
Of course, this may beof little use if you do not have access to the directories. If you cannot find these scripts you should take this up with your DBA.
Cheers, APC

  • Need help with Data Model for Private Messaging

    Sad to say, but it looks like I just really screwed up the design of my Private Messaging (PM) module...  *sigh*
    What looked good on paper doesn't seem to be practical in application.
    I am hoping some of you Oracle gurus can help me come up with a better design!!
    Here is my current design...
    member -||-----0<- private_msg_recipient ->0------||- private_msg
    MEMBER table
    - id
    - email
    - username
    - first_name
    PRIVATE_MSG_RECIPIENT table
    - id
    - member_id_to
    - message_id
    - flag
    - created_on
    - updated_on
    - read_on
    - deleted_on
    - purged_on
    PRIVATE_MSG table
    - id
    - member_id_from
    - subject
    - body
    - flag
    - sent_on
    - updated_on
    - sender_deleted_on
    - sender_purged_on
    ***Short explanation of how the application currently works...
    - Sender creates a PM and sends it to a Recipient.
    - The PM appears in the Sender's "Sent" folder in my website
    - The PM also appears in the Recipient's "Incoming" folder.
    - If the Recipient deletes the PM, I set "deleted_on" and my code moves the PM from Recipient's "Inbox" to the "Trash" folder.  (Record doesn't actually move!)
    - If the Recipient "permanently deletes" the PM from his/her "Trash", I set "purged_on" and my code removes the PM from the Recipient's Message Center.  (Record still in database!)
    - If the Sender deletes the PM, I set "sender_deleted_on" and my code moves the PM from the Sender's "Sent" folder to the "Trash" folder.  (Record doesn't actually move!)
    - If the Recipient "permanently deletes" the PM from his/her "Trash", I set "sender_purged_on" and my code removes the PM from the Sender's Message Center.  (Record still in database!)
    Here are my problems...
    1.) I can't store PM's forever.
    2.) Because of my design, the Sender really owns the PM, and if I add code to REMOVE the PM from the database once it has a "sender_purged_on" value, then that would in essence remove the PM from the Recipient's Inbox as well!!
    In order to remove a PM from the database, I would have to make sure that *both* the Recipient has "purged_on" value and the Sender has a "sender_purged_on" value.  (Lot's of Application Logic for something which should be simple?!)
    I am wondering if I need to change my Data Model to something that allows my autonomy when it comes to the Sender and/or the Recipient deleting the PM for good...
    One the other hand, I believe I did a good job or normalizing the data.  And my current Data Model is the most efficient when it comes to saving storage space and not having dups.
    Maybe I do indeed just need need to write application logic - or a cron job - which checks to make sure that *both* the Sender an Recipient have deleted the PM before it actually flushes it out of my database to free up space?!
    Of course, if one party sits on their PM's forever, then I can never clear things out of my database to free up space...
    What should I do??
    Some expert advice would be welcome!!
    Sincerely,
    Debbie

    rp0428,
    I think I am starting to see my evil ways and where I went wrong... 
    > Unfortunately his design is just as denormalized as yours
    I see that now.  My bad!!
    > the last two columns have NOTHING to do with the message itself so do NOT belong in a normalized table.
    > And his design:
    >
    > Same comment - those last two columns also have NOTHING to do with the message itself.
    Right.
    > The message table should just have columns directly related to the message. It is a list of unique messages: no more, no less.
    Right.
    > Mark gave you hints to the proper normalized design using an INTERSECT table.
    > that table might list: sender, recipient, sender_delete_flag, recipient_delete_flag.
    > As mark suggested you could also have one or two DATEs related to when the delete flags were set. I would just make the columns DATE fields.
    >
    > Once both date columns have a value you can delete the message (or delete all messages older than 30+ days).
    >
    > When both flags are set you can delete the message itself that references the sender and the message sent.
    Okay, how does this revised design look...
    MEMBER --||-----0<-- PM_DISTRIBUTION -->0-------||-- PRIVATE_MSG
    MEMBER table
    - id
    - email
    - username
    - first_name
    and so on...
    PM_DISTRIBUTION table (Maybe you can think of a better name??)
    - id
    - private_msg_id
    - sender_id
    - recipient_id
    - sender_flag
    - sender_deleted_on
    - sender_purged_on
    - recipient_flag
    - recipient_read_on
    - recipient_deleted_on
    - recipient_purged_on
    PRIVATE_MSG
    - id
    - subject
    - body
    - sent_on
    Is that what you were describing to me?
    Quickly reflecting on this new design...
    1.) It should now be in 3rd Normal Form, right?
    2.) It should allow the Sender and Recipient to freely and independently "delete" or "purge" a PM with no impact on the other party, right?
    Here are a few Potential Issues that I see, though...
    a.) What is to stop there from being TWO SENDERS of a PM?
    In retrospect, that is why I originally stuck "member_id_from" in the PRIVATE_MSG table!!  The logic being, that a PM only ever has *one* Sender.
    I guess I would have to add either Application Logic, or Database Logic, or both to ensure that a given PM never has more than one Sender, right?
    b.) If the design above is what you were hinting at, and if it is thus "correct", then is there any conflict with my Business Rule: "Any given User shall only be allowed 100 Messages between his/her Incoming, Sent and Trash folders."
    Because the Sender is no longer "tightly bound" to the PRIVATE_MSG, in my scenario above...
    Debbie could send 100 PM's, hit her quota, then turn around and delete and purge all 100 Sent PM's and that should in no way impact the 100 PM's sitting in other Users' Inboxes, right??
    I think this works like I want...
    Sincerely,
    Debbie

  • PL/SQL I need to find the data for practice

    Please don't laugh at my question, since it is sort of nieve question. I had bought a call Oracle database 10g pl/sql programming so that I can practice on my laptop by installing the express edition.
    I installed oracle express edition and hard coded as per book, but I don't have the data file where the sql or pl/sql command will pull as per its commands.
    I looked the book here and there and the publisher's website. What I find they have codes in the website whic I can download or copy from the book or write on my own,
    Can anyone will help me or show the rope how I can get the data and continue my practice with enjoyment, Thank you in anticipation

    Hi!
    What data r u taking about? Is it data from Employees,Department ... tables or data from any other table? If it is the first one - and if u installed Oracle in your labtop. Then u may find there is another scheama called HR which is generally locked. U have to unlock that account and then u can proceed with ur query which will give the exact data that u r looking for. Hope that will help.

  • SSRS adhoc (2005/2008) - Need to create Report Model (.smdl file) for adhoc using Stored procedure

    Hi All,
    I need to create Report Models using stored procedures. But whenever I am going to create data sources for same, I am just getting tables and views to use. Please see the screenshot below:
    Is there any way out to create data source based on stored procedure? Please help.
    Thanks in Advance
    Regards
    Kumud

    Hi Kumud,
    As per my understanding, it is not support to create a Datasource View (DSV) using stored procedures.
    In a DataSource View, only views, tables or named queries can be used. We can use stored procedures in a query. No parameterized queries, parameterized stored procedures or parameterized UDFs can be used in a DSV named query. You can try to using below approach
    to achieve what you are require:
    To build views in our relational source and add the views to the datasource view to proceed with modelling.
    There is a similar issue, you can refer to it.

  • Need the AD Link cable for SB X-Fi and other models. Anyone have an unneeded one?

    Need the AD Link cable for SB X-Fi and other models. Creative is out of stock & discontinued. Anyone have an unneeded one? TIA.

    This will do it perfectly. http://www.cableyourworld.com/prodde...?prod=CYW-1755
    I once swapped such a cable with the one supplied by Creative because I needed a few extra inches of length. Therefore my recommendation is no gamble, it is a certainty. The only reason I would anticipate failure is if the PIN 1 matching is not performed on both the sound card and I/O bay. I have also seen people turn the cable upside down as well.

  • Data Model for EM....Just need to get data.

    Hi guys,
    Does Oracle provide a data model for EM? What we are trying to do is retrieve some information that is stored in the repository. ie: CPU usage, Disk Usage, etc, etc...
    I know we can get this info from doing some shell scripts as well as querying the DB, but we wanted to get this data directly from the repository as we feel it covers all the area's we need to capture our Capacity and Performance planning metrics.
    Any suggestions would be helpful, or if you understand what I am trying to acheive, then hit me up with a way to get this.
    Thanks again guys.

    Hi,
    As you can see in this link the part is longer manufactured and it does not have a replacement.
    In terms of functionality, you can try using the component PLL_VIRTUAL in Multisim to replace it in a high level simulation or create a new component of a replacement that you have the SPICE model of.
