What's the difference between RSS and Atom feeds?

I just figured out the RSS thing, which is great. However, when I go to sign up for a RSS feed, I am often given a choice between RSS, Atom, sometimes different versions of RSS. What's the difference between all these? (I tried searching, but was unsuccessful.) How do I make a choice?
Another question, can someone see that I have signed up for RSS feed from their site?

Hi again,
but how do people decide which one to use for subscribing?
People can choose whichever one they want - Safari supports both RSS and Atom, other applications on OS X (and Microsoft Windows, Linux, etc) may only work with RSS or Atom so by publishing in multiple formats they can be fairly sure that everyone can read the content.
And how can you see who has subscribed to an RSS feed from your site?
They will be able to see the IP address of the requester in just the same way as they can when you load a webpage - there's no difference in how the RSS/Atom data is requested sent over the internet compared to HTML webpages.

What is the difference between DSo and Infocube

Hello,
Kindly tell me what is the difference between DSO and Infocube?
And please tell me how to take the desicion that in whichi case we can use DSO and in which case we can use Infocube..

Hi ,
DataStore object serves as a storage location for consolidated and cleansed transaction data or master data on a document (atomic) level.
This data can be evaluated using a BEx query.
A DataStore object contains key fields (for example, document number/item) and data fields that can also contain character fields (for example, order status, customer) as key figures. The data from a DataStore object can be updated with a delta update into InfoCubes and/or other DataStore objects or master data tables (attributes or texts) in the same system or across different systems.
Unlike multidimensional data storage using InfoCubes, the data in DataStore objects is stored in transparent, flat database tables. The system does not create fact tables or dimension tables.
Use
The cumulative update of key figures is supported for DataStore objects, just as it is with InfoCubes, but with DataStore objects it is also possible to overwrite data fields. This is particularly important with document-related structures. If documents are changed in the source system, these changes include both numeric fields, such as the order quantity, and non-numeric fields, such as the ship-to party, status and delivery date. To reproduce these changes in the DataStore objects in the BI system, you have to overwrite the relevant fields in the DataStore objects and set them to the current value. Furthermore, you can use an overwrite and the existing change log to render a source delta enabled. This means that the delta that is further updated to the InfoCubes, for example, is calculated from two successive after-images.
An InfoCube describes (from an analysis point of view) a self-contained dataset, for example, for a business-orientated area. You analyze this dataset in a BEx query.
An InfoCube is a set of relational tables arranged according to the star schema: A large fact table in the middle surrounded by several dimension tables.
Use
InfoCubes are filled with data from one or more InfoSources or other InfoProviders. They are available as InfoProviders for analysis and reporting purposes.
Structure
The data is stored physically in an InfoCube. It consists of a number of InfoObjects that are filled with data from staging. It has the structure of a star schema.
The real-time characteristic can be assigned to an InfoCube. Real-time InfoCubes are used differently to standard InfoCubes.

What is the difference between #variable_name and :variable_name?

Hi!
What is the difference between #variable_name and :variable_name?
I have found that if we use alphanumeric variable then :variable_name return value in quotes but #variable_name without quotes.
Why it does not work in the same way for variable default values when variable is used in filter? (It works in mapping)
I use variable in filter like T.OUT_DATE>convert(datetime,:LAST_UPDATE_DATE,121)
When I use my variable in package and do refresh it works fine. But when I try to execute the same interface with variable default value I get error. Seems that variable name has been not changed to the value. It does not work with default value in quotes neither without quotes.
Any ideas how to solve that?
Thank you in advance!
Edited by: user13278245 on Sep 15, 2010 4:34 AM

Question is how to make it work with default value, when I execute interface standalone, not in package? And why it works in mapping but not in filter?
+ I have found that it works if source is Oracle. It doesn't work only for MS SQL source.

What is the difference between start() and run()

Hi:
what is the difference between start() and the run()???
in my app, i have
Console.debug( "starting thread to listen for clients" );
_server = new Server( this );
_server.start();
_server extends Thread..
why everytime i use server.start(); my app will terminate on it is own, even though in my servr.run() method, i have a while loop
and if i call _server.run() explicitly in my code, that while loop will be in execution
can someone let me know??
thnx

what is the difference between start() and the
run()???start() is a method on Thread that tells it to start.
run() is a method in the object that the thread executes.
why everytime i use _server.start(); my app will
terminate on it is own, Err.... I'm not convinced this is true. It'll throw an IllegalThreadStateException, if you try to restart an existing thread.
If that's what you're saying.
even though in my _servr.run()
method, i have a while loopI don't see the connection. Are you saying that the while loop never terminates, and you don't see why the thread is terminating?
and if i call _server.run() explicitly in my code,
that while loop will be in executionIf you call server.run() explicitly, then run() will be executed in the same thread that you called it in.

What is the difference between exists and in

hi all
if i have these queries
1- select ename from emp where ename in ( select ename from emp where empno=10)
and
2- select ename from emp where exists ( select ename from emp where empno=10)
what is the difference between exists and in is that only when i use in i have to bring the field name or what.... i mean in a complex SQL queries is it will give the same answer
Thanks

You get two entirely different result sets that may be the same. Haah! What do I mean by that.
SQL> select table_name from user_tables;
TABLE_NAME
BAR
FOO
2 rows selected.
SQL> select table_name from user_tables where table_name in (select table_name from user_tables where table_name = 'FOO');
TABLE_NAME
FOO
1 row selected.
SQL> select table_name from user_tables where exists(select table_name from user_tables where table_name = 'FOO');
TABLE_NAME
BAR
FOO
2 rows selected.So, why is this? the WHERE EXISTS means 'if the next is true', much like where 1=1 being always true and 1=2 being always false. In this case, where exists could be TRUE or FALSE, depending on the subquery.
WHERE EXISTS can be useful for something like testing if we have data, without actually having to return columns.
So, if you want to see if an employee exists you might say
SELECT 1 FROM DUAL WHERE EXISTS( select * from emp where empid = 10);
If there is a row in emp for empid=10, then you get back 1 from dual;
This is what I call an 'optimistic' lookup because the WHERE EXISTS ends as soon as there is a hit. It does not care how many - only that at least one exists. It is optimistic because it will continue processing the table lookup until either it hits or reaches the end of the table - for a non-indexed query.

What's the difference between thunderbolt and mini displayport?

I'm trying to connect my Macbook with a monitor and I'm thinking of what cable to get. I will have to connect using a (Thunderbolt to HDMI cable) or a (mini displayport to HDMI cable).
I was wondering what's the difference between Thunderbolt and mini displayport
Thanks

@bontistic: it is not true that only the Macbook Air supports Thunderbolt. All models(!) support thunderbolt: also the Macbook Pro's and Mini's. Eg.: http://www.apple.com/nl/macbookpro/features.html#thunderbolt
My Macbook Pro from 2011 already supported Thunderbolt...

What is the difference between TO_CHAR and TO_DATE()?

Hi everybody,
i am facing a problem in my system.It is quite urgent, can you explain me "What is the difference between TO_CHAR and TO_DATE()?".
According to user's requirement, they need to generate a code with format "YYMRRR".
YY = year of current year
M = month of current month (IF M >=10 'A' ,M >=11 'B' , M >=10 'C')
RRR = sequence number
Example: we have table USER(USER_ID , USER_NAME , USER_CODE)
EX: SYSDATE = "05-29-2012" MM-DD-YYYY
IF 10
ROW USER_ID , USER_NAME , USER_CODE
1- UID01 , AAAAA , 125001
2- UID02 , AAAAA , 125002
10- UID010 , AAAAA , 12A010
This is the original Script code. But This script runs very well at my Local. Right format. But it just happens wrong format on production.
12A010 (Right) => 11C010 (Wrong).
SELECT TO_CHAR(SYSDATE, 'YY') || DECODE( TO_CHAR(SYSDATE, 'MM'),'01','1', '02','2', '03','3', '04','4', '05','5', '06','6', '07','7', '08','8','09','9', '10','A', '11','B', '12','C') ||     NVL(SUBSTR(MAX(USER_CODE), 4, 3), '000') USER_CODE FROM TVC_VSL_SCH
     WHERE TO_CHAR(SYSDATE,'YY') = SUBSTR(USER_CODE,0,2)
     AND TO_CHAR(SYSDATE,'MM') = DECODE(SUBSTR(USER_CODE,3,1),'1','01',
          '2','02', '3','03', '4','04', '5','05',
          '6','06', '7','07', '8','08', '9','09',
          'A','10', 'B','11', 'C','12')
I want to know "What is the difference between TO_CHAR and TO_DATE()?".

try to use following select
with t as
(select TO_CHAR(SYSDATE, 'YY') ||
         DECODE(TO_CHAR(SYSDATE, 'MM'),
                '01', '1',
                '02', '2',
                '03', '3',
                '04', '4',
                '05', '5',
                '06', '6',
                '07', '7',
                '08', '8',
                '09', '9',
                '10', 'A',
                '11', 'B',
                '12', 'C') as code
    from dual)
SELECT t.code || NVL(SUBSTR(MAX(USER_CODE), 4, 3), '000') USER_CODE
FROM TVC_VSL_SCH
WHERE SUBSTR(USER_CODE, 1, 3) = t.codeand yes you need check time on your prodaction server
good luck

What is the difference between upgradation and migration.

Hi Guru's
what is the difference between upgradation and migration.
actuallly i involved in upgradation project, here my role is
1. first i check the query's in 3.5 save the query and transport the query. and check the query in bex analyzer also.
2. go to BI .7 find the query;s ,give the query name and save the query ,
3. once save the query, again will come to 3.5 open the query , it will not open. this is my job here,
come to 7.0 check the query in analyzer also.
i am having littile bit confusion, how it will comes query in 7.0, why are u saving the query's in 3.5 and 7.0
query's already available in 7.0 why are u doing this work?
can i know the upgrades those objects, is it neccessary, if necessary how can i upgrade.
infoobje , transferrules, transferstructure ,infosoure, datasoure,updaterules, ods, cubes.
Points will be Assingned ,
Thanks & Regards
prabhavathi

Hi,
I was talking in a general sense not on a query level.
If your taling about migration in that level meaning as a part of larger upgradation (in your case 3.x to 7) there may be many places where you need to do this kind of activities.
Fr eg migration into new data flow, Migration of Web templates from BW 3.x to Netweaver 2004s, etc
Hope this helps.

What is the difference between ws_upload and gui_upload

what is the difference between ws_upload and gui_upload
what is the difference between ws_download and gui_down load
pls tell briefly

Hi Kuamr,
UPLOAD and DOWNLOAD, the function modules used until now are not part of the standard set of ABAP commands. They are used to display the file interface on the presentation server. UPLOAD and DOWNLOAD are not compatible with USs and have been replaced by GUI_UPLOAD and GUI_DOWNLOAD.
The new function modules, GUI_UPLOAD and GUI_DOWNLOAD, have an interface that also allows you to write Unicode format to the local hard drive. For a description of these interfaces, refer to the documentation for each function module, available under SAP Easy Access " Development " Function Builder " Goto " Documentation.
Instead of using the function modules, you can use the static methods GUI_UPLOAD and GUI_DOWNLOAD of the global class CL_GUI_FRONTEND_SERVICES.
Hope this resolves your query.
Reward all the helpful answers.
Regards

What is the difference between Service and Component

What is the difference between Service and Component?

Generally, the implementation of a service will be comprised of many components, each of which will be comprised of many objects.
Services should correspond to cohesive collections of use cases (eg an online bank), components are at a finer granularity (eg a table of numbers).

What's the difference between SNC and SRM?

we will sell SNC in Q2.But i don't know what is the difference between SNC and SRM.
i've heard SNC suit Direct procurement better than SRM...
Pls give me the advice and information.
good regards kenji

Hi Kenji,
SRM is more of Supplier Identification and SNC work of building
relationship with Supplier starts after this Supplier identification.
SNC is very Good tool to handover Inventory replenishemnt
to Suppliers and it gives Visibility of inventory information over Web UI.
SNC has many processes like PO Collaboration, SMI, DR,DCM, SNI,
Invoice Collaboration,Release process...to accomplish above mentioned task.
SNC is designed for direct materials procurement.
SRM has contract negotiations,bids,auctions for sourcing to identify suppliers
SRM is good for basic purchasing fuctionality and suitable for indirect materials.
In addition to all these SNC has Customer Collaboration functionality also.
