To me.

Message is an XML content in an XSD schema..... which can be parsed and mapped...

File is an container that hold the XML message in a Raw form, such as tab delimited, comma seperated, PDF etc... we read the file content to form a Message.....

As Michal replied a file will have a message and not all message will have a File.... i.e.

In case of JDBC scenario Message comes from an Database where the data is stored as Records/tuples.

In case of IDoc scenario Message comes from an IDoc where the data is stored as a Segment....

In case of Mail scenario Message comes from an eMail wher the data is stored as an attachement/mail content...

So File is a container for an Message &

Message is an common term used to represent an Data...

Hi Gautam,

A file is generic like flat file or exce/pdf files.

But messages can be anything like a file or jdbc records, soap requests etc... So a file is a subset of message (every file can be considered as a message in PI , but not the other way)

Dear Gautam,

If you are asking in based on PI we can define like as follows:

File - The message container (For example, an .XML or .TXT or .CSV)

Message - The content of a file (For example, XML elements, data or text or CSV file data)

So JP you mean message or file are same. If that is the situation then why we have 2 name to one thing.

Thanks

Dear Gautam,

I don't say both are same. I'll let you give real world example. For example, if an XML file contains the details of a car manufacturing material records as follows.

<?xml version="1.0" encoding="UTF-8"?>

<GOODS>

<NUT>10</NUT>

<BOLT>10</BOLT>

<WHEEL>4</WHEEL>

</GOODS>

This is called as message.

How can we store this message in a location? As a file we can store with the extension .XML. So while storing the content in a location it is called as file. While the same content is processed or sent to some interfaces then we call it as message.

Hi JP,

If I have understood correctly

File :- Storing of a message content in a location is file.

Message: - When file is transmitted in a channel / medium it becomes message.

So Message = File

Please correct me if I am wrong.

Thanks

Yes , almost correct...

[JaganMohan]

Dear Gautam,

Correct (in interface point of view)...:)

Could you please be more eleborative like

Thanks

Hi,

in terms of interfaces file can be a message (or inside the message)

but a not every message needs to have a file inside (it can also be jms, jdbc, email message)

Michal ,

What I feel JMS, JDBC, eMail is the median to transfer the file but they are not message.

I feel the same with the file.

Thanks
