Please write the difference between ODS and DSO...

Hi all,
Please write me the differences between ODS and DSO.. I think both are same in structure and have same update types (Over write, Addition) and also with the tables (changelog, Activation queue, Active table).. Is there still a difference between ODs and DSO...I can assign the points..
thanks

Please what the difference between MFP1132 AND MFP1136 LASERJET PRINTER

please what the difference between MFP1132 AND MFP1136 LASERJET PRINTER

Nothing definite, but http://mindmachine.co.uk/products/HP_Texts/HP_LJ_Pro_M1130_01.html suggests that:
The MFP1132 (part number CE847A) is for American and European markets, and uses the CE285A toner cartidge.
The MFP1136 (part number CE849A) is for Asian markets, and uses the CE388A toner cartidge.

What is the difference between ODS and PSA?

DIFFERENCE BETWEEN ODS AND PSA?

hi..
ODS:
Stores consolidated data on the document level.
Data is stored in transparent tables.
Reporting is possible.
Represented on the database by three transparent tables.
Stores Transaction data.
Can merge data from different infosources.
Can be defined as a datasource for another Bw system.
ODS has granular data, it is volaital.
ODS having the Over write functionality
contains Current data
PSA:
It is source system dependent.
Stores data in 2-D format.
We can edit data in PSA.
Reporting is not possible.
used mainly for performing manual update or simulate update or reconstruction.
partition is possible.
Data stored in psa can be used for several purposes.
Repeated delta updates possible.
Error handling posibility.
Structure of PSA is called as Trasfer structure.
It stores the data exactly like how the data is presented in the source system.
We have psa and ODS but we can't do reporting on PSA
You can do reporting in ODS , In PSA u cant do reportin directly
ODS contains detail -level data , PSA The requested data is saved, unchanged from the source system. Request data is stored in the transfer structure format in transparent, relational database tables in the Business Information Warehouse. The data format remains unchanged, meaning that no summarization or transformations take place
In ODS u have 3 tables Active, New data table, change log, In PSA u dont have
We can only add in PSA and change, add and delete in ODS.Is the statement true?
we can edit/add the records in PSA and delete the records,
i thjink its not possible to edit the records in ODS, u can delete the records, and u can add records in ODS
check out this link..
PSA and ODS
hope it helps..

Could someone please explain the difference between 3g and cellular please. Many thanks.

Please could someone explain the difference between an i pad with wi fi + 3g and wi fi + cellular, thank you

Older iPads got 3G service and were called Wi-Fi + 3G. Newer iPads can connect to faster cellular networks and those are given different names by the major carrier so to simplify things Apple calls the newer models Wi-Fi + Cellular.
iPads with 3G or Cellular are NOT used like a mobile phone. They do not make phone calls or send SMS or MMS text messages, They do connect to the data network and can connect to the web.

What is the difference between ntp and ctssd ?

hello everyone
could you please describe the difference between ntp and ctssd? which one should be used?
thanks
John

ntp is OS level service which synchronize the system clock with a remote server over the Network Time Protocol (NTP).
CSSD oracle processes (Cluster Services Synchronization Daemon) monitor the health of RAC nodes employing two distinct heart beats: Network heart beat and Disk heart beat. Healthy nodes will have continuous network and disk heartbeats exchanged between the nodes.

What is the difference between Firefox and Internet Explorer?

I'm an older woman and it's hard for me to keep up with all the new technology these days. Can someone please explain the difference between Firefox and Internet Explorer? Which one is better to use? Many thanks for your help.

Firefox, Chrome and Internet explorer are all types of Browser; for use (mainly) on the internet, other modern browsers are Safari & Opera.
Just to confuse things slightly, Windows Explorer, is the name of the software that is usually used to look at content (files & folders) on Windows PCs.
Maybe these articles will help

Can anyone please let me know the differences between EDW and BI 7 if any.

hi,
As such their is no diff between the to
The Enterprise Data Warehouse (EDW) is a service offered by the Data Services Department of the Information Services and Technology Division. EDW consolidates data from multiple sources in support of campus wide decision making and related information needs such as reporting, analysis, and planning.
The vision for the EDW is to provide information that is secure, accurate, timely, consistent, integrated, appropriately detailed, well-organized, and easy to obtain so that people throughout the campus -- staff, faculty, researchers, and executive-level administrators -- will be better able to assess their needs, set priorities, understand the impact of change, and fulfill their programmatic responsibilities more efficiently.
The major components of the existing Enterprise Data Warehouse are:
BAIRS Financials
BAIRS HRMS
BIS
Legacy BIS
Student Data Warehouse Pilot
AND BI 7 is the latest version of the EDW which is currently in used in full fledged everywhere with lots of added functionality.

Please give the diagrams to explain the difference between MVC1 and MVC2

Please give the functional diagrams to explain the difference between MVC1 and MVC2

there is no MVC1 or MVC2, only the MVC pattern. The implementation of the MVC is fairly open-ended and there are some variations that are not named as different "versions" because each variation still has the same pattern: there is a model, there are views and there are controllers. What you list as a "feature" of MVC2 in your other post:
http://forum.java.sun.com/thread.jspa?threadID=719812&tstart=0
is merely the implementation of a front controller (becoming more popular nowadays) in stead of using multiple controllers. There is no change in pattern, only in implementation.

What is the difference between Firefox and Firefox os please. I have a Samsung galaxy s3 mini what one would you recommend would be better for my phone

What is the difference between Firefox and Firefox os, and what one is better for the Samsung galaxy s3 mini, Please could you recommend which one is the best and most suitable for my phone please. Many thanks Michelle Petch

Thank you for your question.
Firefox is basically a browser.And Firefox OS is an Operating System.You can install Firefox in your SGS3 just like an android application.But if you want Firefox operating system on it. then you have to flash the ported Firefox OS on your device. Then it will be a completely different standalone operating system.you cannot install android applications on it.
To read more technical difference read:

What is the difference between MOVE and WRITE TO ststement?

Hi
What is the difference between MOVE and WRITE TO ststement?
When do we use both of them?
Thank You

Hi,
<b>MOVE</b>
Syntax
MOVE source {TO|?TO} destination.
destination {=|?=} source.
Effect
Both these statements assign the content of the operand source to the data object destination. The variants with the language element TO or the assignment operator = are valid for all assignments between operands that are not reference variables, and for assignments between reference variables for which the static type of source is more specific than or the same as the static type of destination(narrowing cast).
Variants with the language element ?TO or the assignment operator ?= (casting operator ) must be used if the source and destination are reference variables and the static type of source is more general than the static type of destination (widening cast). For assignments between operands that are not reference variables, use of the question mark ? is not permitted.
The data object destination can be any data object that can be listed at a write position, and the data object source can be a data object, a predefined function or a functional method (as of release 6.10). The data type of the data object destination must either be compatible with the data type of source, or it must be possible to convert the content of source into the data type of destination according to one of the conversion rules.
Notes
If source and/or destination are field symbols, then, as in all ABAP commands, the system works with the content of the data objects to which the field symbols point. The actual pointer content of a field symbol can only be changed using the statement ASSIGN or the addition ASSIGNING when processing internal tables (value semantics). If source and destination are reference variables, the reference contained in source is assigned to destination (reference semantics).
Strings and internal tables are addressed internally using references. When assignments are made between strings and between internal tables (as of release 6.10), only the reference is transferred, for performance reasons. After the assignment, the actual string or the actual table body of the source as well as the target object are addressed (sharing). When the object is accessed to change it, the sharing is canceled and a copy of the content is made. The sharing is displayed in the memory consumption display of the ABAP debugger and in the Memory Inspector tool (as of release 6.20).
Obsolete Form: MOVE PERCENTAGE
Exceptions
Catchable Exceptions
CX_SY_CONVERSION_NO_NUMBER
Cause: Operand cannot be interpreted as number
Runtime Error: CONVT_NO_NUMBER (catchable)
CX_SY_CONVERSION_OVERFLOW
Cause: Overflow with arithmetic operation (type P, with specified length)
Runtime Error: BCD_FIELD_OVERFLOW (catchable)
Cause: Operand too large or (intermediate) result too large
Runtime Error: CONVT_OVERFLOW (catchable)
CX_SY_MOVE_CAST_ERROR
Cause: Source or target variable are not reference variables
Runtime Error: MOVE_CAST_REF_ONLY
Non-Catchable Exceptions
Cause: Source field (type P) does not contain correct BCD format.
Runtime Error: BCD_BADDATA
Cause: Assignment for deep structures not permitted if these overlap.
Runtime Error: MOVE_COMPLEX_OVERLAP
Cause: Type conflict with the assignment between object references.
Runtime Error: MOVE_INTERFACE_NOT_SUPPORTED,
Runtime Error: MOVE_IREF_NOT_CONVERTIBLE,
Runtime Error: MOVE_IREF_TO_OREF,
Runtime Error: MOVE_OREF_NOT_CONVERTIBLE
Cause: Type conflict with the assignment between data references.
Runtime Error: MOVE_DREF_NOT_COMPATIBLE
Cause: Assignment between the types involved not supported.
Runtime Error: MOVE_NOT_SUPPORTED
Cause: Constants and literals must not be overwritten.
Runtime Error: MOVE_TO_LIT_NOTALLOWED
Cause: onstants and literals must not be overwritten.
Runtime Error: MOVE_TO_LIT_NOTALLOWED_NODATA
Cause: During a loop in an internal table, an attempt was made to overwrite a reference variable that is linked with the internal table by REFERENCE INTO.
Runtime Error: MOVE_TO_LOOP_REF
<b>Write</b>
Syntax Diagram
WRITE - TO
Syntax
WRITE {source|(source_name)} TO destination
                             [int_format_options].
Effect:
This statement assigns the formatted content of the data object source, or the formatted content of the data object whose name is contained in source_name, to the data object destination. The data objects source_name and destination must be character type and flat. source_name can contain the name of the data object to be assigned in upper or lower case. If the data object specified in source_name does not exist, the assignment is not executed, and sy-subrc is set to 4.
The statement WRITE TO has the same effect as the statement WRITE for lists. This statement formats the content of source or the source field specified in source_name as described in the field. It does not, however, store the result in an output area of a list in the list buffer, but instead stores it in a variable. The output length is determined by the length of the variable.
The same additions int_format_options can be specified for formatting the content as in the statement WRITE for lists, except for NO-GAP and UNDER.
System fields
sy-subrc Meaning
0 The data object specified in source_name was found and the assignment was executed.
4 The data object specified in source_name was not found and the assignment was not executed.
For the static specification of source, sy-subrc is not set.
Note:
If destination is specified as an untyped field symbol or an untyped formal parameter, and is not flat and character-type when the statement is executed, this leads to an untreatable exception in a Unicode program. In non-Unicode programs, this only leads to an exception for deep types. Flat types are handled as character-type data types.
Example:
After the assignment, the variables date_short and date_long receive the current date in the order specified in the user master record. The variable date_long also contains the defined separators, as the output length is sufficiently long. The content of the variable date_mask is formatted according to the formatting addition DD/MM/YY.
DATA: date_short(8) TYPE c,
      date_long(10) TYPE c,
      date_mask(8) TYPE c.
WRITE sy-datum TO: date_short,
                   date_long,
                   date_mask DD/MM/YY.
Exceptions
Non-Catchable Exceptions
Cause: Negative length specified for offset/length
Runtime Error: WRITE_TO_LENGTH_NEGATIVE
Cause: Negative offset specified in offset/length
Runtime Error: WRITE_TO_OFFSET_NEGATIVE
Cause: Offset specified in offset/length specification is longer than the field length.
Runtime Error: WRITE_TO_OFFSET_TOOLARGE

What is the difference between ABAP and HR-ABAP?

Hi people,
Could u just tel me abt what is the difference between ABAP and HR-ABAP?
Thanks in advance,
Sanjeev K.V

Hi Sir ,
Please have a look below .Hope it is suitable and simpler solution for your question.
Please do reward if useful.
Thankx.
HR deals with the INFOTYPES which are similar to Tables in General ABAP.
There are different ways of fetching data from these infotypes.
There are different areas in HR LIKE Personal Admn, Orgn Management, Benefits, Time amangement, Event Management, Payroll etc
Infotypes for these areas are different from one another area.
storing of records data in each type of area is different
LDBS like PNP are used in HR programing.
Instead of Select.. we use some ROUTINES and PROVIDE..ENDPROVIDE.. etc
and in the case of Pay roll we use Clusters and we Import and Export them for data fetching.
On the whole Normal ABAP is different from HR abap.

For Personal Admn the Infotypes start with PA0000 to PA1999
Time Related Infotypes start with PA2000 to PA2999.
Orgn related Infotypes start with HRP1000 to HRP1999.
All custom developed infotypes stsrat with PA9000 onwards.
In payroll processing we use Clusters like PCL1,2,3 and 4.
Instead of Select query we use PROVIDE and ENDPROVIDE..
You have to assign a Logical Database in the attributes PNP.
Go through the SAp doc for HR programming and start doing.

Look at the below link
And finally,
Few notes are below:
InfoSets in the HR Application
You can use SAP Query in HR to report on HR data. Queries are maintained as described in Creating Queries. The special features of queries created for HR are described in Maintaining Queries in the Human Resources Application. The maintenance procedure for HR InfoSets differs from the described procedure inasmuch as HR data fields are grouped together in infotypes.
InfoSet management in SAP Query is also used for InfoSet Query. For further information, see Functions for Managing InfoSets.
If you want to create InfoSets for HR, you can use logical databases PNP, PNPCE, PAP, and PCH (see HR Logical Databases). The database you must use to create your InfoSet depends on the component in which the data you want to report on is stored.
The reports you can execute using InfoSets based on logical databases PNP (or PNPCE) or PCH are similar, but differ in that they can select different objects. The following table describes the connection between the logical database, and the infotypes you can include in an InfoSet. It also provides you with one or two examples of reports that you can execute using the appropriate InfoSets.
Logical database PNP/PNPCE* PCH PAP
Selection of Persons Objects from Personnel Planning Applicants
Infotypes that can be included in the InfoSet Infotypes for· Personnel Administration (0000-0999) · Time Management (2000-2999) · Payroll infotypes · Infotypes for Personnel Planning objects that can be related to persons If the object type is specified:· Infotypes for the object type · Infotypes for objects that can be related to the specified object typeIf the object type is not specified:· All infotypes · Infotypes for Recruitment (4000-4999)· Some infotypes for Personnel Administration (such as 0001 and 0002)
· Customer infotypes
Reporting examples · Selection of all persons who participated in a specific business event, output of prices for reserved business events · Selection of all persons assigned to a specific personnel area, output of qualifications held by these persons · Selection of all business events held in London in March, output of all persons who participated in these business events · Selection of all positions assigned to a specific organizational unit, output of all persons assigned to the positions · Selection of all applicants hired last year to work on special projects, output of addresses for the applicants selected
Logical database PNPCE (PNP Concurrent Employment) functions just like logical database PNP. The procedure for creating InfoSets is also the same. It only becomes significant if you work with Concurrent Employment.
Creating InfoSets
The maintenance procedure for HR InfoSets differs from the procedure described so far in this section inasmuch as HR data fields are grouped together in infotypes. To set up an InfoSet for the HR application, proceed as follows:
1. On the initial screen for maintaining InfoSets, enter a name for the InfoSet and choose Create.
2. On the next screen, enter a name for the InfoSet and select one of the HR logical databases in accordance with your reporting requirements.
Customer infotypes can be created on all HR logical databases. In each individual case, therefore, you must decide which database to select so that you can report on customer infotypes.
This screen enables you to enter an authorization group. All of the queries that are subsequently created using this InfoSet can only be executed by persons who have this authorization group.
3. Choose .
This takes you to the Infotype Selection for InfoSet screen. You now have the option of creating field groups and assigning fields as required for non-HR InfoSets. Field groups that correspond to infotypes and already contain fields, however, are always created for HR InfoSets. The field groups are displayed in an overview tree in the top right section of the screen.
The infotypes that you included in the InfoSet are displayed in an overview tree on the left of the screen. The infotype fields that are already included in field groups are displayed in a different color, and the corresponding field group ID is displayed.
In the standard system, a field group is created automatically for each infotype that you included in the InfoSet (a field group corresponds to an infotype).
In the standard system, each field group contains the infotype-specific fields. To ensure that working with the InfoSet is as easy as possible, you are advised to restrict your use of fields in each field group to those you really require. This means you should remove fields that are not required.
An infotype's fields must only be assigned to the pertinent field group. Make sure this assignment is correct. If the assignment is incorrect, the InfoSet could be rendered unusable.
When an InfoSet is created, the following fields are transferred automatically to the first field group:
§ Logical database PNPCE or PNP Personnel number
§ Logical database PAP Applicant number
§ Logical database PCH Object ID, plan version, and object type
6. Determine the fields that must be included in the field groups of your InfoSet. If you require further information, see Assigning Fields to a Field Group.
If you want, you can change the default sequence of field groups and fields as required using Drag&Drop.
7. To save the InfoSet, choose .
8. To generate the InfoSet, choose .
On the Change InfoSet (InfoSet name) screen, you can choose Edit ® Change infotype selection to add more infotypes to the InfoSet, or to remove infotypes from the InfoSet. Remember to regenerate the InfoSet afterwards.
This screen also enables you to update InfoSets if, for example, the system contains new additional fields for specific key values. To do so, choose InfoSet ® Additional functions ® Update additional HR fields.
9. Go back to the initial screen for InfoSet maintenance.
10. Choose User group assignment.
11. Select a user group, and save your entry.

What is the difference between occurs0 and occurs1

pls explain about the difference between occurs0 and occurs1 in sap-abap.

Hi Suresh,
WELCOME TO SDN
Please check this link
diff b/w occurs 0 and 1
Occurs 0 and Occurs 1...
Occours 0
Occurs 1 allocates 1 unit of memory(Sufficient to hold one record) and and when one record is appended, one more unit of memory is allocated.
Occurs 0 will allocate memory dynamically.It will not allocate any memory when the itab is declared.
Coming to performance: If you know that you will store only one single value in the Internal table If you use OCCURS 1. It would perform well than OCCURS 0.
Occurs 0 keeps on incrementing when there is a value. But Occurs 1 will assign a single space even though there is no value.
Lets suppose you did not get any values from the DB after a select, in this case if you write Occurs 0 it will not allocate any single space in the memory. If you write OCCURS1 it will pre allocates some memory.
Hope this helps...
Best regards,
raam

What is the difference between QuickTime and iMovie?

Why would I need to upgrade my QuickTime to QuickTime Pro if I have iMovie? If I did have these two programs wouldn't that be redundant? They both edit the same kind of information, right? If you use both programs, please provide pros and cons. Thank you.
iMac G5 Mac OS X (10.4.4)

It would take a book to describe the differences between iMovie and QuickTime Pro, so I won't go down that road. Here's Apple's QT Pro Tutorial, which will help introduce its features:
http://www.apple.com/quicktime/pro/tutorials.html
I use QuickTime Pro every day to help with one task or another. It's a very useful tool, which gets you closer to the basic functions of QuickTime than does iMovie. It also helps you learn more about QuickTime software, the heart of iMovie. Like most other things, the more you understand the fundamentals the more you understand the program using them.
There's one important difference: Unlike iMovie, whatever task you want to perform with QuickTime Pro can also be done with an AppleScript script. So if you have repetitive tasks with movies, QuickTime Pro is a must. Just write a script that you call from within QuickTime Pro to perform just about any task, or collection of tasks. The script literally "tells" QuickTime Pro to perform the task.
I strongly recommend QT Pro for anyone who uses iMovie HD a lot, or who is interesting in understanding the underlying structure of QuickTime movies.
