What is Interface

What is Interface

What is a interface?
In terms of oracle applications interface is a communication channel that allows the data to move in and out of the system.

How many types of interfaces are there?
1.INBOUND INTERFACES
2.OUTBOUND INTEFACES

Inbound InterFace:The one which allows data to get into oracle application from outside is called inbound interface.

OutBound Interface:The one which allows data to get data from oracle applications to other systems is called outbound interface.

What are different types of inbound interfaces available?
1.Open interfaces
2.API's(Application Program Interface)
3.EDI(Electronic Data interchange)--Mainly used for automation transactions with third party systems
4.XML GATEWAY --Mainly used for automation transactions with third party systems
5.WEBADI--Used for uploading data from excel with the scope to have some validations--mainly used for one time loading..Just like sqlloader+validation program..
5. PLSQL Packages for Reading XML Data--Use this in case of importing non standard transactions

What are different types of outbound interfaces available?
1. Custom programs where we pull data to a csv file using UTL_FILE in the required format
2.EDI
3.XMLGATEWAY
4.PLSQL Packages for generating XML

what is the difference between OPEN INTERFACE & API's?
OPEN INTERFACE:
I dont see much difference between the open other than the way we load data.
In case of open interface the data is loaded in to open interfce table like GL_INTERFACE or Sales Order Interface(OE_ORDER_HEADERS_IFACE_ALL).
Run the interface import program.
This will validate the data and put it into oracle applications.All the invalid records are marked as Error.
One thing is there are GUI Screens available for most of these interface where you check the errror message correct it there only and resubmit the interface.
From the technical perspective there are Error tables available for each interface

API:
API's are the oracle built packages where the validation logic is wrapped inside a package and the data is passed as parameters to the API.
Most of these api's use the PLSQL tables as parameters to take the advantage of bulk binding concepts for faster loading data.
They will have the two OUT parameters to throw back the error code and message in case of data validation failure
Apis' are comparatively faster than open interfaces.
If a API's and open interface are available it is better to load through API's.If the records are more...

Interfaces and conversions procedure
Data can feeded in 3 ways

1. The Data can be entered using the application Screens.

2.The data can be entered using Oracle’s Open System Interface.

3. The data can be stored in the database table directly

Conversion An overview of its process

(Inbound Process)

1. Get data from legacy system Called Flat file.

2. Load the flat file data into temporary table called staging table using sqlloader

(control files are used .ctl extensions)

3. Validate the data in staging table using pl/sql procedures to define rules of validation.

4. Successful Validation rakes up the data to the interface tables.

5. These Validate data can be directed to base tables using predefined Seeded programs.

(Outbound process)
 
outbound Interface Process:
=============================

1)Develop the PL/SQL Program (Either Procedure or Package)

2)Write the Cursor to retrieve the data from database tables.

3)Create file or Open the File by using UTL_File.fopen().

4)Open the Cursor

5)If any validations are there write the validations

6)Transfer the Data into File by using UTL_File.Put_Line().

7)Close the Cursor.

8)Close the File by using UTL_File.fclose();

9)Register the Procedure or Package as Concurrent Program and submit from SRS Window.


We will use following three functions to generate the file.

1)Utl_File.fopen     = To open (or) Create the file
2)Utl_File.Put_line  = To Transfer the data into the File.
3)Utl_File.fclose    = To close the File after Data transfer.


Difference between Conversion and Interface

1. Conversion is one-time process 1. Interface is the post production

which is performed once before process. Productions go on live. (Pre-production process)

2. Data comes in to Oracle Applications 2. Interface is the integration of

only (One way process) two systems.

3. Interactive Process 3. Scheduled and repetive process.
 

Open Interface Tables are standard Oracle tables.

-Oracle uses OITs to provide a simple interface to Oracle base tables.

-Oracle has list of all the open interface that oracle offered in their product.

Interface Program



- It is an inbuilt program in most of the modules to pull up the data from the interface table

Under validations sends data to base tables,if validation fails Displays data to Error a error message
