Difference between view and synonym

i want the difference between view and synonym ,and also the cases where view and synonym are used

How this is related to 'issues and concerns with downloads' is beyond my understanding. Your question seems to be related to database and should be re-issued in the database forums.
In the mean time, the definitions of each are given at http://download.oracle.com/docs/cd/B19306_01/server.102/b14220/intro.htm#sthref69

What is the difference between view and materialized views

Hi
What is the difference between view and materialized view ? can we update the base table using views

can we update the base table using viewsYes:
VIEWS
1. an updatable view is one that lets you perform DML on the underlying table
(see Oracle Database Concepts 10g - 5 Schema Objects)
2. non-updatable view requires INSTEAD OF Triggers
(see Oracle Database Concepts 10g - 22 Triggers)
SNAPSHOTS
You can have updateable (and writeable) snapshots - in updateable (writeable) MV replication.
Oracle uses snapshots (Materialized Views - MV) for two different purposes:
1. replication
2. automated Query Rewrite facility (first introduced in Oracle Discoverer, later included in Oracle database 8i).
Replication types in Oracle are:
a) Basic replication (MV replication)
- transaction based
- row-level
- asynchronous from master table to MV (Materialized View)
- DML replication only
- database 7 / 8.0 / 8i / 9i / 10g
- Standard and Enterprise Edition
1. Read-only MV replication
2. Updateable MV replication:
2.1 asynchronous from MV to master
2.2 synchronous from MV to master
3. Writeable MV replication
b) Multimaster replication
- transaction based
- row-level or procedural
- asynchronous or synchronous
- DML and DDL replication
- database 7 / 8.0 / 8i / 9i / 10g
- Enterprise Edition only
1. row-level asynchronous replication
2. row-level synchronous replication
3. procedural asynchronous replication
4. procedural synchronous replication
c) Streams replication
- (redo) log based
- row-level
- asynchronous
- DML and DDL replication
- database 9i / 10g (10g has Down Streams Capture)
- Enterprise Edition only (Standard Edition 10g can execute Apply process)

Difference between view and window ?

Hi All,
Can you tell me a basic difference between view and window , maybe you can correlate your answers with concepts of HTML.
Rajeev

Hi Rajeev,
A window is a place for displaying your views. Your view is not available to the outside world. View is available only to your component. However, your window is an interface view, which can be displayed in other components.
A view contains your UI elements. It has a layout (a window does not). A window contains embedded views.
In the window, you can define how navigation between views takes place (by creating navigation links).

What is the main difference between view and materialize view and advantage of Mview ??

What is the main difference between view and materialize view and advantage of Mview ??

1.A view uses a query to pull data from its associated tables.
2.Views do not have data's physically stored in the Database.
3.Views Get the Data from 2 or more tables and displays as a single block.
4.But a materialized view is a table on disk is a result set of a query done.
5.A Materialized view can have data's in the database.
6.Materialized view are used for Boosting the Performance.
7.And the important one is Materialized views are updated based on the parameters defined when they are created.
8.By using triggers we can update the data in a materialized view.
9.When you call a materialized view it will show the data when it was last updated.
Hope it helps.

Duration difference between viewer and timeline after insertion or overwrit

Reopened project from last week and now when I try to put in a new scene, the duration I give in the viewer changes in the timeline.
i.e. - I overwrite in a 17 frame scene and it becomes a 21 frame scene in the timeline.
All worked well last week, Any ideas?

People have very short attention spans these days. Someday the government will have to put Ritalin in the water supply.
I think I have found my own answer.
The clips that were causing problems were captured at a different frame rate than the timeline.
I didn't do the capture but it is my best guess so far.
I am cutting together movie promos for a television station. Some are off of DVD and some are off of tape.

Is there any difference between 10g and 11g M Views?

Hi,
I need to give a demo on and working examples of materialized views. The requirement is this: Master tables are in a 10g R2 DB, MV is in a 11g.
I just create a DB Link in 11g to point to the 10g DB and then create the MV in 11g.
Will there be any problems creating a 11g MV using 10 Master tables?
My question is are there any significant differences between 10g and 11g MViews??
Thanks & Regards,
Channa.

You have to be careful about your versions. 10g could be 10.1 or 10.2 11g could be 11.1 or 11.2
I wouldn't have an 11.2 database with a database link against a 10.1 database.
In fact, even with 10.2, I would try to ensure that I have a "high patchset" (10.2.0.4 or 10.2.0.5) although, in theory, 10.2.0.1 should also work.

Difference between read and view only -users having both permissions can download the documents

Hi All,
Would like to know whats the difference between view only and read permission.
As per my requirement, my end users who have been assigned View Only should NOT be able to Download the document from a doc lib.Whereas who have Read permissions should be able to download.
But when i tested with few users with these permissions, those users who are having viewonly permissions was able to download the documents.
how this will be true? MS says that this is not possible if it contains server side handlers.
my customer worried about the download-the-document part. as per them end users who have view only permissions should not download the docs.

Hi,
Please check this similar thread:

Your only option is to implement IRM to accomplish your requirement.

What is the difference between 'workbookk' and ' view'?

Hi all,
What is the difference between 'workbook' and 'view'. I check some document but I don't see there is big difference.
Thanks.
J.

hi John,
We use workbooks for excel formating,like font changes, lay out changes etc...
Workbooks into which queries are inserted are no different in appearance than other Excel workbooks.
They can be saved as files, copied, sent and (using Excel functions) edited however you like and even supplemented with other data.
Views are primarily used for BW Web Reports, it is similar to the concept of workbooks is for BEx.A local view can be accessed only within a workbook in which it was saved, where as a global view can be accessed globally in the system, it is not attached to a workbook. Only Global view can be used in BW Web Templates.
u can seee the help doc for more details:

Differences Between Object And System Privileges

Hi,
Whats the difference between object and system privileges in oracle?
Cheers
Paul

System Privileges
A system privilege is the right to perform a particular action, or to perform an action on any schema objects of a particular type. For example, the privileges to create tablespaces and to delete the rows of any table in a database are system privileges.
Schema Object Privileges
A schema object privilege is a privilege or right to perform a particular action on a specific schema object:
For example, the privilege to delete rows from the departments table is an object privilege.
Some schema objects, such as clusters, indexes, triggers, and database links, do not have associated object privileges. Their use is controlled with system privileges. For example, to alter a cluster, a user must own the cluster or have the ALTER ANY CLUSTER system privilege.
A schema object and its synonym are equivalent with respect to privileges. That is, the object privileges granted for a table, view, sequence, procedure, function, or package apply whether referencing the base object by name or using a synonym.
Granting object privileges on a table, view, sequence, procedure, function, or package to a synonym for the object has the same effect as if no synonym were used. When a synonym is dropped, all grants for the underlying schema object remain in effect, even if the privileges were granted by specifying the dropped synonym.

Exact difference between VOimpl and VORowimpl and EO.

Can anybody tell me whats the exact difference between
VOimpl and VORowimpl and EO.
Thanks

Entity Object :BC4J entity objects encapsulate the business rules (validations, actions and so on) associated with a row in a database table, view, synonym or snapshot.
View Object : (ViewImpl)
In the simplest terms, a BC4J view object encapsulates a database query and provides iteration over and access to the view rows in its result set.
View Row : ViewRowImpl :
Represents a single row in a view object.

What is difference between abstraction and encapsulation ?

Hi,
I am trying to figure out the difference between abstraction and encapsulation but confused.
Both are used for data hiding then what is the exact difference ?
Thanks.

When you encapsulate something you get an inside and an outside. The outside is the abstraction. It describes how the encapsulated entity behaves viewed from the outside. This is also called the type. Hidden inside is the implementation. It holds detail information about how the type's behaviour is accomplished.
It's a very simplified picture but I think it's quite accurate and it works for me.

What is the difference between SWF and F4V in the context of Streaming or progressive Download?

Hello everybody,
I am absolutely a beginner in working with Captivate and furthermore my technological know how is not that good.
So, I have problems to understand if the export formats SWF and F4V are both capable to be published in the Internet as streaming video and as progressive Download? Well so, I do not really understand the difference between streaming and progessive download either?
Furthermore I was asking myself if this issue depends on how I imported flash videos (there are these two options) in my Captivate project during the production phase?
I would be very thankful for some helping information!
Greetings,
Mareike the beginner

Welcome to our community
I'm not certain I fully understand the differences myself, but will toss out what I believe to be true about the formats. Hopefully, if I'm incorrect in my bellief, someone with more definitive knowledge will chime in.
It was explained to me a couple of years back and is my understanding that "streaming" only applies to a video based format such as F4V, FLV and it doesn't apply to SWF. With SWF, you may specify a preload value. So when the SWF transmits from the web server to the PC, a certain percentage has to be received before play begins. But that's not streaming. It's preloading.
For streaming to occur, the web server establishes a communication channel between the server and the destination PC. This channel is monitored to see what speed is in use. Only enough information is then transmitted to be comfortable at that speed. If the speed improves during the connection, the server serves data at a faster rate. If the connection degrades, the information transmitted is also scaled back so as to accommodate the lower speed.
With SWF, after it has all been downloaded, a savvy user is able to poke around in their temporary internet files and save the SWF for play later. With streaming, this isn't possible because as the stream is viewed, it evaporates from memory.
Seriously hoping others will chime in here to confirm or deny this.
Cheers... Rick

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... 
In 9i, there is a Migration Guide whereas in 10g there is a Upgrade Guide. 
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. 
Others think upgrade when new version replace database in place, and migration when new version include a move of database. 
Another point of view is : upgrade is for technical, and migration for application/data. 
 
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.

Difference between mtl_system_items and mtl_system_items_b

Hi All,
Can anyone tell me the difference between mtl_system_items and mtl_system_items_b ?
Regards,
Shruti

mtl_system_items is a synonym that points to mtl_system_items_b
mtl_system_items used to be the actual items table in older versions.
But in recent version the mtl_system_items_b is the items table. If any old code was using mtl_system_items, the synonym helps it compile and thus make this change backward compatible.
Oracle follows the following convention to handle multi-language.
The b stands for base table. And then there is a table called tl (e.g. mtlsystem_items_tl). In the _tl table, for each base record, you can find multiple records - one for each language that you use.
Hope this answers your question,
Sandeep Gandhi
