  CAT

  CAT is a synonym for USER_CATALOG.
  . . .
  USER_CATALOG

  USER_CATALOG lists all the tables, views, clusters, synonyms, and sequences belonged to the current user. Its columns are the same as those of "ALL_CATALOG".
  . . .
  DICT

  DICT is a DICTIONARY.
  . . .
  DICTIONARY

  DICTIONARY contains descriptions of data dictionary tables and views.
  . . .
  TAB

  TAB is included for compatibility. Oracle recommends that you do not use this view.
  >
  TAB has been deprecated. He looks like the cat because it shows the USER objects, but it does not show the sequences, like the cat.

  If you look at the source code for the views TAB and USER_CATALOG you can see the differences. This code is copyrighted by Oracle Corporation, all rights reserved.

  Hello

  How can I tell the difference between delete and insert in a process using Apex 5.0

  Do you really mean 'database trigger', or are you referring to a process of page APEX? Ensure that the tabular form MRU delete process conditional on the button DELETE and that the MRU update process is conditional on the "SAVE" button.

• Difference between 'Form' and 'object '.

  I am writing today a guide in my native language and want to understand the difference between 'Object' and 'Form' for Illustrator. We have menu object in the Panel and can find a few options of forms under this menu.

  Also we program this object is:

  In computing, an object can be a variable, a data structure, a function or a methodand as such, is a location in memory value and possibly referenced by an identifier.

  In class-based object-oriented programming paradigm, 'object' refers to an instance of a class where the object can be a combination of data structures, functions, and variables.

  Relational database management, an object can be a table or column or an association between data and entity of database (such as the age of a person concerning a particular person). ^[1]

  So my question is: If we create a form in artificial intelligence can we call it 'object' and vs. ?

  There is menu item "Create object mosaic" option which works only with raster images. This is why any other object in artificial intelligence is not object?

  Thank you

  "In illustrator is an 'Application based on the objects' any item placed in the drawing area that you can select is called" object "where as".

  a form is an object of two dimension.

  We could say : each form is an object , BUT not every object is a form.

• What is the difference between Count (*) and Count (1)?

  Hello

  can you please what is the difference between Count (*) and Count (1)?

  I saw that Count (*), Count (1), Count (2)... etc return values from a table. Is there an exact difference between them?

  Have you read the forum space FAQ? I'm sure that you don't have because it is answered there.

  It is also answered via Google.

  The short answer is: there is no difference, unless you use count (1), count (2), etc. instead of count (*) it makes you look like an amateur.

• What is the difference between Oracle and MySQL

  Hello
  
  I would like to know the major difference between Oracle and MySQL. I have a project to generate tables of database XML files, I used the functions XML built oracle XMLELEMENT, XMLAGG XMLATTRIBUTES, XMLFOREST. I really want to know if these functions (or) similar functions are taken into charge/availabe in MySQL.
  
  I'm having a hard time finding better linux distro to install Oracle11g, so I intend to move to MySQL. Please help, thanks in advance.

• difference between BYTE and CHAR

  Hi all
  
  Oracle, as in syntax below, what is the difference between BYTE and CHAR used as size data type for the column NAME:
  
  CREATE THE CUSTOMER TABLE
  (
  NAME VARCHAR2 (11 BYTE),
  CUSTOMER_ID NUMBER
  )
  
  and
  
  CREATE THE CUSTOMER TABLE
  (
  NAME VARCHAR2 (11 CHAR),- or even VARCHAR2 (11)
  CUSTOMER_ID NUMBER
  )
  
  
  
  Rgds,
  PC

  First - do not use reserved words for column (NAME).

  If the database character set is UTF-8, which I believe is the default value in the recent version of Oracle. In this case, some characters take more than 1 byte to store in the database.

  If you set the field as VARCHAR2 (11 BYTE), Oracle will allocate 11 bytes for storage, but you can not actually be able to store 11 characters in the field, because some of them take more than one byte to store, for example, non-English characters.

  By setting the field as VARCHAR2 (11 CHAR) you tell Oracle to allocate enough space to store 11 characters, regardless of the number of bytes it takes to save each of them. I think that in Oracle 10g, 3 bytes per character were used.

  Kind regards

• What is the difference between EPMA and Essbase Studio

  If the two are not used to design applications?
  
  And a really need Essbase Studio?

  What is the difference between EPMA and Essbase Studio

  ^ ^ ^ It's a little confusing, isn't? As far as I understand the role of EPMA, it is a way to share dimensions and common data between several products Oracle EMP including Planning, Essbase and HFM. In fact, I don't know if other products live in EPMA. What is EPMA not have is a great way to supply or manipulate the dimension and fact tables (or files). Oh, there are tables of the interface, but you will write the code/use the utility of dimension EPMA to load dimensions. I must say that I never tried to load through EPMA data so that someone else will have to pronounce on it. Once the dimensions are built, you can deploy Essbase (and other products) of common and specific to the database dimensions.

  Studio is the tool you will use to go against a data warehouse, or something terribly close a data warehouse to build Essbase databases. Just for Essbase - HFM, planning, etc. are not the targets of the Studio release.

  What gets confusion / intriguing, is that when EPMA deploy Essbase apps, it uses Studio under the covers to do. So the interesting implementations where people use Studio (which is much more flexible than EPMA because it is a development tool as opposed to a dimension/data management application) to read the tables, EPMA interface (and as far as I know, the EPMA base tables) and create Essbase applications like that.

  If you think that there is overlap, I agree with you, but you can see that they are not the same.

  And a really need Essbase Studio?

  ^ ^ ^ Do not use Studio to build Essbase databases. You can go hog wild in EAS with loading SQL rules if you want, even if at some point it will be probably easier and simpler to build in the Studio. Although the Studio has been mentioned as the replacement of EAS for awhile, I suspect the effort required to build a database in Studio will keep around for quite a while EAS or Studio Lite will be out. There is a lot to say (sometimes) for the incredible flexibility EAS/Essbase-Studio requires a more methodical approach and EPMA has a very formal set of standards and methods.

  Phew, I'm sorry, I wrote a book on this subject and I bet you get a lot of differences of opinion on that.

  If you are interested in the Studio, you could do well to take a copy of 'Look smarter than you are with Oracle Essbase Studio 11' of Glenn Schwartzberg. I don't get a penny from the sale while I was among the writers of copy (Hey, I got a mention in the acknowledgements). It's a good book and an excellent introduction to the tool.

• What is the difference between oracle and peoplesoft databases

  What is the difference between oracle and peoplesoft databases. How the tables of metadata between the two relate?
  
  According to my understanding, peoplesoft database exists as a schema on the oracle database.
  Please correct me if iam wrong.

  user4212454 wrote:
  ...
  The second statement, I realized that each schema created its specific use.
  for example, peoplesoft had 1000 objects (including the peopletools and application and system tables), each schema created above has access restrictions different on these database of 1000 objects. Am I wrong?

  Yes, each schema has its own purpose and the grant for objects of Peoplesoft. SYSADM is the owner of the objects of Peoplesoft with all rights. PS is the owner of one and same table, PSDBOWNER and the PEOPLE is granted to select three of these tables (PSOPRDEFN and PSACCESSPRFL PSDBOWNER).

  In addition, for DB2, what are the patterns of PeopleSoft?

  It is located in the installation documentation dedicated to the database you want to work on:
  http://download.Oracle.com/docs/CD/E15742_01/PSFT/HTML/docset.html

  The first statement, could you please elaborate on the part highlighted.

  A "Peoplesoft database" is nothing, it's terms to refer to a database containing everything you need to make a Peoplesoft application running.

• CDC: Difference between coherent and Simple mode?

  Hello
  
  I would like to know if anyone can explain the main differences between the two modes of the CDC?
  
  In fact, we are interested in implementing a DCC ODI asynchronous Oracle newspaper.
  But we would like to make sure that it matches our needs.
  
  I understand that the simple mode is on a table and the consistent on several articulated together.
  But my questions are:
  
  -Could we choose to log table for only some of the columns.
  -> If in my table, I'm not interested in the change of some columns, I can 'say' to the CDC do not watch?
  or the CDC can tell me which column had been updated?
  
  -in fact, I would like to know what is the difference between Simple and consistent? and if the mode is just a Simple mode for more than one table?
  Cause, we need to know what the source columns had been updated for each record, not only the primary key of the record being updated.
  
  I know that Oracle CDC allows it, but I don't know if ODI enable us to see only the columns that have been updated.
  
  
  Thanks in advance
  
  Brice

  Hi Brice,.

  AFAIK for a coherent CDC referential integrity must be set at the level DB (PK, FK).
  Personally I have never used any logical key, so I'd rather hear for a few experienced comments.

  Thank you

• Difference between getRowCount() and getFetchRowCount()

  Hello
  
  
  What is the difference between getRowCount() and getFetchRowCount()?
  and where to use this method.
  
  Thank you and best regards,
  Jean Blaise

  Jean Blaise,

  getRowCount() causes the whole view defined subject line must be extracted from intermediate level.

  getFetchRowCount:-This tells us the number of lines that have been recovered in all lines, and not pull additional lines in some of the other methods 'get count' will love.

  That said, if you have a table with a default row area of say 10 lines per page, then fetchrowcount will display 10 at a time and getrowcoutn will show whole row in VO.

  int fetchedRowCount = vo.getFetchedRowCount (); Print the number of line exposed in a table at the same time

  vo.getRowCount (print as many rows in VO)

  Thank you
  -Anil

• Difference between fetch and cache

  Anyone know the difference between recovery and caching when ITS analyses a source? In the document below under Maintenance crawls, it says in step 4 that the robot will pick up the item. This means - it downloads in the memory of the Server HIS?
  
  He also says, in step 5, it compares the checksum of the file that is located in the cache. Is this the same cache is place of conservation for indexed content needs? Any help on this would be greatly appreciated!
  
  Thank you
  dhartle
  
  Here's the source document: http://download.oracle.com/docs/cd/E10502_01/doc/search.1018/e10418/crawler.htm#i1004689
  
  Analysis of maintenance
  After the initial analysis, a page of the URL is only ramp and indexed if it has changed since the last scan. The robot determines if it has changed with the HTTP If-Modified-Since header field or the checksum for the page. URL that no longer exist are marked and removed from the index.
  
  To update the modified documents, the robot uses an internal checksum to compare the new Web pages with caching of Web pages. Change of Web pages are cached and marked for re-indexing.
  
  The steps involved in the synchronization of the data are:
  
  1 oracle creates the robot according to the schedule that you specify with the administration tool. The queue of the URL is filled with the URLS of seeds of the source assigned to the schedule.
  2. the robot launches several crawling threads.
  3. each chenille wire removes the following URL in the queue.
  4. Each robot thread retrieves the document from the Web. The page is usually an HTML file containing text and hyperlinks. When the document is not in HTML format, the robot tries to convert the document to HTML before caching.
  5. each chenille wire calculates a checksum for the newly recovered page and compared to the checksum of the cached page. If the checksum is the same, then the page is ignored, and the robot goes to step 3. In the contrary case, the robot will move to the next step.
  6. each chenille wire Scans the document hyperlinks and inserts new links in the queue of the URL. The links that are already in the document table are ignored. (Oracle ITS doesn't follow links binary documents filtered.)
  7. the robot marks the URL as "accepted". The URL is parsed in the future, maintenance tests.
  8. the robot saves the URL in the document table.
  9. If the file system cache is full or the URL queue is empty, the cached Web page stops and commences. Otherwise, the thread of Caterpillar again step 3.

  "This means it downloads in the memory of the Server HIS?"-Yes.

  "He also said to step 5 that it compares the checksum of the file that is located in the cache. Is this the same cache which is the place of conservation for content that is indexed? "- Yes, but I'm sure that the checksum (as calculated to the last time) is stored in a table, so that it is not actually access the cached file.

• Difference between 'Reload' and "Reload (Override Cache)"?

  Https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly#w_navigation, what is the difference between 'Reload' and "Reload (Override Cache)"? What makes "ignore cache"?

  Reloading Web pages and cache bypass aims to obtain a new copy of perhaps obsolete or damaged files currently stored in the disk cache.
  You can do it like the first attempt if a normal charging does not seem to provide a version of a Web site or if you are having problems with a Web site otherwise.

  We usually have advice that if you have questions:

  Reload Web pages and ignore the cache to refresh potentially stale or corrupt.

  • Hold down the SHIFT key and click the Reload button
  • Press 'Ctrl + F5' or 'Ctrl + Shift + R' (Windows, Linux)
  • Press 'Command + shift + R' (Mac)

  Clear the cache and delete cookies only from Web sites that cause problems.
  "Clear the Cache":

  • Firefox/tools > Options > advanced > network > content caching Web: 'clear now '.

  'Delete Cookies' sites causing problems:

  • Firefox/tools > Options > privacy > "Use the custom settings for history" > Cookies: "show the Cookies".

  Start Firefox in Safe Mode to check if an extension or theme (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problems.
