Difference Between Data Type and Data Object

Difference Between Data Type and Data Object

hi magesh
Data types can be divided into
elementary,
reference, and
complex types.
Elementary Types
Elementary types are the smallest indivisible unit of types. They can be grouped as those with fixed length and those with variable length.
Fixed-Length Elementary Types
There are eight predefined types in ABAP with fixed length:
Four character types:
Character (C),
Numeric character (N),
Date (D),
and Time (T).
One hexadecimal type:
Byte field (X).
Three numeric types:
Integer (I),
Floating-point number (F)
and Packed number (P).
Variable-Length Elementary Types
There are two predefined types in ABAP with variable length:
STRING for character strings
XSTRING for byte strings
Reference Types
Reference types
describe data objects that contain references (pointers) to other objects (data objects and objects in ABAP Objects).
Data Types
1) As well as occurring as attributes of a data object, data types can also be defined independently.
2)You can then use them later on in conjunction with a data object.
3) The definition of a user-defined data type is based on a set of predefined elementary data types.
4) You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary.
5) You can use your own data types to declare data objects or to check the types of parameters in generic operations.
Data Objects
1)Data objects are the physical units with which ABAP statements work at runtime.
2) The contents of a data object occupy memory space in the program.
3) ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type..
4) For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
5) Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type).
6) You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures).
7) As well as fields in the memory area of the program, the program also treats literals like data objects.

Differences between DATA TYPE and DATA OBJECTS

I am new to ABAP,I want to know the differences between DATA TYPE and DATA OBJECTS with some examples.
please help me regarding this.

Hi Ashish,
Data Types:       Are pure descriptions.
               No memory is associated with data types.
               Describes the technical properties of data objects.
EX.
1.     C-CHARACTER
2.     D-DATE
3.     F-FLOAT
4.     I-INTEGER
5.     N-NUMERIC TEXT
6.     T-TIME
7.     P-PACKED NUMBER
8.     X-HEXADECIMAL
9.     STRING-Variable length string.
10.     XSTRING-Variable length byte string.
Data Objects: Are created during runtime.
                They cannot exist without the data Types.
                Occupies memory space.
EX:
1.     INTERNAL DATA OBJECT- Internal Data objects
     LITEERAL- A literal has a fixed value.Ex: WRITE:u201DWORK HARDu201D.
     VARIABLES: Data statement is used to create variables.
EX.DATA: NUM TYPE I.
NUM: VARIABLE defined by data statement.
EX: DATA: PRICE LIKE NUM.
     CONSTANT-It is a data object, which contains a constant value throughout the program.
Can be declared in program by using CONSTANT statement.
EX:CONSTANT: INT TYPE I VALUE 15.
2.     EXTERNAL DATA OBJECT: Are defined in tables i.e In ABAP/4 dictionary you can access this data from table.
         EX: TABLES: SFLIGHT
          DATA: SEATS LIKE SFLIGHT-SEATSMAX.
3.     SYSTEM DEFINED DATA OBJECTS:Space & system variables like SY-UNAME,SY-DATUM, SY-REPID.
4.     SPECIAL DATA OBJECTS:
     PARAMETERS: Are Variables ,which can accept value from user.
      SELECTION SCREEN : Are special internal tables to accept value ranges from user.
3 APPROACHES TO DEFINE DATA OBJECTS.
1.     ELEMENTARY TYPES
DATA: Customer _Name (25) TYPE C,
               Vendor_Name (25) TYPE C.
2.     REFRENCE TO AN EXISTING FIELD:
DATA: Customer _Name2 (25) TYPE C,
              Vendor_Name2 (25) LIKE Customer_Name2
3.     REFRENCE TO NON-ELEMENTARY TYPE:
TYPES: T_NAME (25) TYPE C
DATA: CUSTOMER_NAME TYPE T_NAME
               VENDOR_NAME TYPE T_NAME
4.     RECORD-Information in rows & columns.
DATA: BEGIN OF BOOKING,
                                ID (4) TYPE C,
                                FLIGHT_DATE TYPE D,
                                NAME LIKE CUSTOMER_NAME,
                                END OF BOOKING.
You can also look into SAP help for more information.

Hi Friends ....Difference between SAP memory and ABAP memory

Hi Friends,
I faced a interview and they ask this question
What is the difference between SAP Memory and ABAP memory..

conti
SAP Memory
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement.
Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens.
ABAP Memory
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
A simple example of ABAP memory is using the EXPORT/IMPORT statements.
Here in this program, I get the data, export it to memory,
clear out the internal table in my progam, then reimport the data into it and write out the data.
You probably wounldn't do this in a normal program,
but this is how you can pass data from program a to program b when A Submits program B.
report zxy_0002 .
data: it001 type table of t001 with header line.
select * into table it001 from t001.
export it001 = it001 to memory id 'ZXY_TEST'.
clear it001. refresh it001.
import it001 = it001 from memory id 'ZXY_TEST'.
loop at it001.
write:/ it001-bukrs, it001-butxt.
endloop.
SAP Memory
SAP memory is a memory area to which all main sessions within a SAPgui have access.
You can use SAP memory either to pass data from one program to another within a session,
or to pass data from one session to another.
Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters).
These parameters can be set either for a particular user
or for a particular program using the SET PARAMETER statement.
Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement.
The most frequent use of SPA/GPA parameters is to fill input fields on screens
ABAP/4 Memory
ABAP memory is a memory area that all ABAP programs within the same internal session can access
using the EXPORT and IMPORT statements.
Data within this area remains intact during a whole sequence of program calls. To pass data
to a program which you are calling,
the data needs to be placed in ABAP memory before the call is made.
The internal session of the called program then replaces that of the calling program.
The program called can then read from the ABAP memory.
If control is then returned to the program which made the initial call, the same process operates in reverse.
SAP memory
The SAP memory, otherwise known as the global memory,
is available to a user during the entire duration of a terminal session.
Its contents are retained across transaction boundaries as well as external and internal sessions.
The SET PARAMETER and GET PARAMETER statements allow you to write to, or read from, the SAP memory.
ABAP/4 memory
The contents of the ABAP/4 memory are retained only during the lifetime of an external session
(see also Organization of Modularization Units).
You can retain or pass data across internal sessions.
The EXPORT TO MEMORY and IMPORT FROM MEMORY statements allow you to write data to, or read data from, the ABAP memory.

Difference between Report painter and abap query .

can anyone please tell me the difference between the report painter and the ordinary alv,clasical reporting and also the difference between Report painter and abap query. How the output format will be in Report painter. If anyone has any documents please send it to
[email protected]
Thanks,
Joseph.

hi,
ABAP Query is an ABAP Workbench tool that enables users without knowledge of the ABAP programming language to define and execute their own reports.
In ABAP Query, you enter texts and select fields and options to determine the structure of the reports. Fields are selected from functional areas and can be assigned a sequence by numbering.

whereas the Report Painter enables you to report on data from various applications. It uses a graphical report structure that forms the basis for the report definition. When defining the report, you work with a structure that corresponds to the final structure of the report when the report data is output.

Difference between Data staging and Dimension Table ?

Difference between Data staging and Dimension Table ?

Data Staging:
Data extraction and transformation is done here.
Meaning that, if we have source data in flat file, we extract it and load into staging tables, we take care of nulls, we change datetime format etc.. and after such cleansing/transformation at then end, load it to Dim/Fact tables
Pros: Makes process simpler and easy and also we can keep track of data as we have data in staging
Cons: Staging tables need space hence need memory space
Dimension Table:
tables which describes/stores the attribute about specific objects
Below is star schema which has dimension storing information related to Product, Customer etc..

Difference between Data Provider and extractor.

Hi
Can someone help me in understanding difference between data providers and data extractor.
I have gone through some documents but not able to get the exact difference between them.
What is the exact role of data provider and extractor with respect to sap solution manager.
Is data provider== Data extractor?
Thanks,
Vijay

Hello Vijaya,
From my perspective the Data Providers are responsible for collecting metric values from the monitored objects on the managed sources systems and sending these to the Solution Manager Monitoring and Alerting Infrastrucure.
Data extractors on the other hand are the reporting objects which are defined on the BW part of Solution Manager and can be enabled by configuring some monitoring scenario's. Once these data extractors are enabled, they will use the data from the "Data Providers" (see above) to setup nice BW reportings on the Solution Manager monitoring dashboards.
I hope this answer helps you.

Difference Between data target and infoprovider

Hi Experts,
I am new to BW
What is the difference between data target and infoprovider
Thanks and Regards,
saveen

Hi Saveen,
InfoProvider is an object on which BEx queries are created. It provides information (data) to the queries when they are executed. InfoProviders may contain data (like cube) or may not contain data (like multiproivder and InfoSet).
Data Target is an object to which you will load the data, like cube, ODS or InfoObject. But it is not necessary that each data target is an InfoProvider...like you may have ODS objects that are not enabled for reporting, but you are loading data to them for staging purpose.
Hope this helps...

Difference between Data-centric and Document-centric use

Hi,
Can someone suggest what exactly is the difference between Data-centric and Document-centric use and examples if any.
Thanks in advance.
Chaitanya

Maybe it helps if you look at it this way...
Document centric: document centric use of xml data is data that you always use in its complete form. If you want to use the data, then you always will retrieve it as one entity or you save it as one entity. You are not interested in the xml data / information inside this "package" / document, you are only interested in its total form. Lets say, you have an invoice which can be printed on one sheet of paper. This paper that contains you data, will always be treated in a document driven way, that is, in its total representation: information containted on a sheet of paper (document).
Data centric. data centric use of xml, is usage of data were the main interest point is focused on only pieces of the total set of xml data within a document. So instead of being interested in the whole invoice, you only are interested in information like "amount of money to be payed" or "invoicenumber".
Handling of XML data comes with (hidden) costs. Knowing how your data will be used, has to be used, is one of the first steps in designing you environment (and will have an big impact if you choose poorly). For instance, if you know that your data will always be handled (and must be stored) in a document driven way, then it will make sense to store it based on CLOB based XMLType storage. This will garantee best performance retrieval for your xml document. If you now that your xml data has to be stored so that it can be handled in a data centric way, then Object Relational XMLType storage. If conditions are setup properly data retrieval, inserts and updates will be more cost efficient then when based on CLOB XMLType storage.
There are more differences and "cost markers" when or when not to use CLOB, OR or for instance Binary XML. The first two chapters of the XMLDB Developers Guide for Oracle 11g will give you a good head start making some of those decisions. Be also aware that you probably will have to make compromises. The current state of XML, for example, doesn't have the final solution yet for a uniform storage method.

Difference Between Data type and message type

Hi,
    i have doubt on data type and message type.why we are mapping the message type why not data type?wht is the difference between data type and message type?

Hi Narayanana,
Data type defines the structure of your xml message.Message type is the wrapper of data type.You will be using your message type while mapping and not the data type.Its the abstraction concept used in oops

Hi Suresh,
Data Type defines the structure of the message and it will be wrapped under Message Type.
Hope the details below will clearify your doubts.
A data type in a programming language is a set of data with values having predefined characteristics. Examples of data types are: integer, floating point unit number, character, string, and pointer.
The characteristic of columns and variables that defines what types of data values they can store.
Check out the details:

A message type comprises a data type that describes the structure of a message. At the following points in SAP Exchange Infrastructure you can refer to the message to be exchanged at runtime by using the message type:

Difference between data form and data grids

Can anybody tell me what is the difference between data form and data grid.
Regards

data forms have restricted access. user can not access all the dimension and members, based on his role and authentication can access the form.
data grid r used for calculation, currency translation and coslidation and it consists of menu of options for diffrent consolidation based on cell status.
data grid can have line item information, description and cell status information.

Difference between Data Grid and Data Forms

Hi all,
What is the difference between data grid and data forms.

Data entry forms are pre defined and are generally used to manually input data into reporting (financial statement) schedules.
They can also be used for reviewing purposes and it gives users a presentable / and consistent format to view data in Hyperion.
Data grids are the equivalent of pivot tables in excel. It should be used for ad hoc purposes to view / analyse data in whatever form you choose. The user has the flexibility to choose what they see in the rows, columns and page dimensions.
One of the main differences between data entry forms and data grids is that you can’t export data grids to excel whereas you can with data entry forms. Other differences are:
1. Run consolidation, translation, promotion from data grids but not in data entry forms.
2. You can link other data entry forms to a data entry form
3. Data entry forms offer greater formatting options than in data grids i.e. colours, fonts, bold, italics.
At the end of the day, they are similar and there is no reason why you can’t have (use) both. It all depends on your local needs on how best you use both.
I hope above information helps.

Upgrade from BW 3.5 to BW 7.0 (BI 7.0)
Some features of BI 7 are
1. In Infosets now you can include Infocubes as well.
2. The Remodeling transaction helps you add new key figure and characteristics and handles historical data as well without much hassle. This is only for info cube.
3. The BI accelerator (for now only for infocubes) helps in reducing query run time by almost a factor of 10 - 100. This BI accl is a separate box and would cost more. Vendors for these would be HP or IBM.
4. The monitoring has been imprvoed with a new portal based cockpit. Which means you would need to have an EP guy in ur project for implementing the portal !
5. Search functionality hass improved!! You can search any object. Not like 3.5
6. Transformations are in and routines are passe! Yess, you can always revert to the old transactions too.
