Difference between database and application

can any one tell me difference between oracle database and oracle application?
plz

BUT THE REAL PROBLEM is :-i want to connect that database..
i can't see my imported application or database..
Tell,, should i create any database or what should i
do..tell me detail step by step processFirst and foremost, you have a terminology problem. I will provide a working set of definitions. (But I fully expect to be corrected by some of the symantic specialists.)
- A database, in Oracle's terms, is a set of files.
- Inside of that database are a number of schemas, or collections of object definitions,
- Some of those objects are tables, which may contain data.
- The database is manipulated by an instance, or collection of processes and/or threads
- An application connects to the instance and requests specific manipulation.
In your case, you used the imp application, connecting to the XE database using the userid 'system' to import the schema objects from the schema 'jadi' to the schema 'yogesh'.
You could now use the application called SQLPlus to connect to the XE database - possibly using user "system" - to inspect the objects and object data imported in schema yogesh.
You might also be able to use the Application Express browser-based application to access the data in the various schemas. To do that we would need to explore other terminology such as "workspace"
I would encourage you to use the documentation at http://www.oracle.com/pls/xe102/homepage and perhaps search for the tutorial on the Products page (see the products link on the documentation page.)

  • What is the difference between apps and applications?

    I have an application that I've been running on my older Mac. Now that I have a new MacBook Pro, I have to reinstall new software that is compatible. When I go to the vendor website I see an application I can download or a link to the Mac App Store. Is an application different than an app? When should you download them from a vendor website and when should you go to the app store? Do apps end up in the Launchpad and an application in your Applications folder? I can't seem to find information on what is the distinction. Are they actually two different things? Any help would be appreciated.

    No difference between apps and applications. If you download the app from the Apple AppsStore you have better security and a conveninet place to have all your downloads. Nothing wrong with downloading from a trusted developer though.
    EDIT: Yes they will either wind up in your Download folder as  a .dmg you will have to double-click on to install, or most app store apps will install to your Applications folder.

    What is your Oracle version (4 digits) ?
    What is the column type used to store the date ?
    What is the client time zone ?
    See this example about TIMESTAMP WITH LOCAL TIME ZONE data type:

  • Communicating between Database and Application

    How is it possible to debug a stored procedure from the forms runtime, while it is running?

    It isn't automatic ...
    1. You can use plsql debugger, i.e. you have to have your procedure/function/package compiled with debug info and then invoke event 10938 (?) this will generate more information than you can handle. BTW this method is surely for the faint for hearts and should be implemented * only * after consultation with OWS.
    2. Build your own debug routines, that dump informational messages at critical points in code execution. If you want to implement this, you must forget about dbms_output package. This package is completely useless in this regard. Use utl_file or dbms_pipe instead.
    With some clever coding you may be able to toggle this debug message generation on/off at runtime.
    3. Wait for next release of Forms9i, when used with DB 9i, you get a new debugger that is much more flexible and capable.
    I have successfully implemented 1 and 2 as mentioned above. The 3rd, I heard at ODTUG 2001 from Forms Team.

  • Could any one tell me what is the difference between swfloader and module loader?

    Hi  All,
                          Could any one tell me what is the difference between SWFLoader and Module Loader in Flex3 in detail?

    Hi,
    ModuleLoader is a kind of strange API that is really just intended to look like SwfLoader for modules that contain a single visual component, and hides most of the module loading infrastructure, which is all about class factories.
    What I mean by "only loaded once" is that if you have several places in the code that call the ModuleManager.getModule("url").load() call, it will only ever get loaded over the wire and interpreted once, subsequent "loads" will just re-dispatch pseudo-load events to the new client.  In other words, the class factory is a singleton for a given url. Unloading is a totally different story.  As you note, not everything is truly unloadable, because there may be lots of references to stuff in
    the module that will keep it alive and un-GC'ed.
    I suggest playing with the low-level API so that you understand the backing implementation, and this should help you understand the limits of ModuleLoader.
    The main difference between modules and applications is that modules have lower overhead, and they only ever get loaded once, no matter how many times you load them. If you're using the ModuleLoader API, keep in mind that you're losing about half the functionality of the module system.  I will assume that you are, because otherwise it would be obvious where to expose methods.  You might want to play around with the lower level ModuleManager API just to get a hang of what's going on - ModuleLoader is a pretty thin veneer over the lower API.                
                    Basically, what you want to do is to have your module implement an interface, say IModuleWhatever.
    Also try and refer to this link which was previously discussed in this forum..

    This is fully covered in the documentation:
    About Database Applications
    About Websheet Applications
    About Packaged Applications
    There is little difference between packaged applications and database applications, other than that packaged applications are supplied by Oracle and database applications are created by you.

  • Difference between upgrdae and migration about oracle database

    Difference between upgrdae and migration about oracle database
    please give the comments

    Well, the question is almost philosophic...<br>
    In 9i, there is a Migration Guide whereas in 10g there is a Upgrade Guide.<br>
    Furthermore, in 9i, there is the command line startup migrate whereas in 10g that's startup upgrade.
    Somebody think upgrade when go to new release, and migration when go to new version.<br>
    Others think upgrade when new version replace database in place, and migration when new version include a move of database.<br>
    Another point of view is : upgrade is for technical, and migration for application/data.<br>
    <br>
    Well, after these explanations, your upgrade/migratation notion will not be more clear, but I think that is not very important, only a terminology game. The most important is to know what you need : new version or new release.<br>

  • Difference Between Database Schema and Database User Account ??

    First i would like to know what an Oracle Database schema exactly is ?
    And what is it for and also What is it's use ?
    Later the exact "Difference Between Database Schema and Database User Account".
    I googled about it but i'm unable to find out it's The difference,

    Greate example. but i would like add one more point..
    a user is a schema and schema is a user. but when this applies to the user that he become a schema, only if he has got some objects. so we can say while creating the user which dosent contain any objects called simple user account but afterwords when he has got an objects then we can say its a schema as the above user has shown you through the exampleIt is just word-play. There is nothing in like a 'status' indicator to say "USER_A is just a user but USER_B has become a schema". Many people use the terms "user" and "schema" interchangeably, and some very good DBAs will insist this is correct. I don't disagree with them even though I usually try to make the distinction.
    In a typical application, all of the objects (tables, procedures, etc) that implement the app will be owned by a "application schema owner" - a user which exists for the sole purpose of owning the schema. Said user will have no privileges at all .. especially not CREATE SESSION. Except for possible maintenance activity no one ever actually connects as this user. User accounts are then given to actual humans who connect with their own accounts. The accounts have the necessary system and object privileges granted to them - via a role. One could also create a special account (let's call it APP_ADMIN) that is used for maintenance and batch operations within the application.

  • Difference Between Shutdown and Close Database

    Hi all,
    Let say I want to start the instance of database with the following processes :
    1. STARTUP MOUNT
    2. ALTER DATABASE OPEN
    With two commands above, now the database is open. Then, I want to close the database with command :
    3. ALTER DATABASE CLOSE
    After this, I want to reopen the database again by using this :
    4. ALTER DATABASE OPEN
    I know that it will produce an error because when the database is opened and closed, its lifetime has already ended, so we must shutdown it first.
    My questions are :
    1. What's the difference between CLOSE and SHUTDOWN ? Suppose in the case above, I want to close the database. Why don't I just type SHUTDOWN ? Why is it necessary for me to use command CLOSE instead of SHUTDOWN ?
    2. What are the conditions of database when I CLOSE database, also, what are the conditions of database when I SHUTDOWN database ? I want to know more detail because I have tried to find in google, but now satisfying result
    Thanks before
    Edited by: cycon on Nov 8, 2010 9:00 AM

    alter database close;this you can execute only from OPEN status
    when ever you close the database it will go to mount status here you cannot open the database again, you need to clean sutdown and need to startup.
    alter database open;ths you can execute only on MOUNT status, it will takes you to mount --> open status.
    Thanks

  • What are the Basic Differences between Oracle and  MS-SQL server Database?

    Hello,
            anybody pls Guide me about the Differences between Oracle and MS-SQL server Database.and also IBM Databases also
    Regards,
    Balaram

    SQL Server only works on Windows-based platforms, including Windows 9x, Windows NT, Windows 2000 and Windows CE.
    In comparison with SQL Server , OracleDatabase supports all known platforms, including Windows-based platforms, AIX-Based Systems, Compaq Tru64 UNIX, HP 9000 Series HP-UX, Linux Intel, Sun Solaris and so on.
    The SQL Server  advantages:
    SQL Server  holds the top TPC-C performance and price/performance results.
    SQL Server  is generally accepted as easier to install, use and manage.
    The Oracle  Database advantages:
    Oracle  Database supports all known platforms, not only the Windows-based platforms.
    PL/SQL is more powerful language than T-SQL.
    More fine-tuning to the configuration can be done via start-up parameters.

  • What are the differences between Oracle and other NoSQL database

    Hi all,
    I would like to know what the differences between Oracle and other NoSQL database are.
    When and why should we use Oracle?
    Is Oracle NoSQL database link with Big Data Appliance?
    Can we use map-reduce on a single personal computer? How should we install Oracle NoSQL database to use map reduce on a single personal computer?
    Do we also have eventual consistency with Oracle NoSQL database? Can we lose data if master node fails?
    Are transactions ACID with Oracle NoSQL database? How can we prove it?

    http://www.oracle.com/technetwork/database/nosqldb/overview/index.html
    Is Oracle NoSQL database link with Big Data Appliance?Yes, Oracle NoSQL Database will be a component of the Big Data Appliance.
    Can we use map-reduce on a single personal computer? How should we install Oracle NoSQL database to use map reduce on a single personal computer?Yes, I believe you can run M/R on a single computer. Consult the various pieces of documentation available on the web. You may run Oracle NoSQL Database on the same computer that you are running M/R on, but it is likely that they will compete for CPU and IO resources and therefore performance may suffer.
    Do we also have eventual consistency with Oracle NoSQL database? Yes.
    Can we lose data if master node fails?If you run Oracle NoSQL Database with the default (recommended) durability settings, then if the master fails, a new one will be elected and data is not lost.
    Are transactions ACID with Oracle NoSQL database? How can we prove it?Yes, each operation is executed in an ACID transaction. The API has the concept of "multi" operations which allow the caller to perform multiple operations on sets of records with the same major key, but different minor keys. Those operations are also performed within a transaction.
