Put origin into context
Each input remains traceable as the origin of the information it provides.
Expert topic · Data sources
Understanding input channels in data integration.
When data enters with different structures, naming or context across channels, its operational meaning cannot always be inferred from the receiving system alone. Before central preparation, the input channels and their accompanying metadata are therefore reviewed together.

01 · Origin
Make inputs visible
Start by identifying the channels through which information arrives.
02 · Context
Compare structures
Naming, completeness, context and meaning can differ between inputs.

Prepare for processing
Reviewing inputs provides the material for a central information logic.
Starting point
Where data originates matters.
Input channels do not necessarily deliver the same kind of information in the same structure. That is why looking only at the later target system is not enough.
A clear view of origin shows which data and metadata are available and where their meaning or context needs to be clarified.
Step by step
Capture inputs before normalising them.
The input side of the information flow is described separately from later preparation and delivery.
-
01
Name the channels
Begin with the paths through which data and metadata arrive.
-
02
Put information into context
Compare available structures, naming and context without prematurely treating them as equivalent.
-
03
Describe the differences
The differences provide a clearer picture of what central preparation needs to consider.
Functional value
A more reliable basis for the next stage of the information flow.
Consider metadata
The review considers not only data values, but also naming and context.
Prepare for normalisation
The captured differences guide later normalisation and delivery.

Questions for the input side.
This page explains the origin and characteristics of information. It does not replace detailed planning for specific systems.
- Which channels provide data and metadata?
- Where do structure, naming or context differ?
- Which information is already available?
- Which differences matter for later preparation?
Frequently asked questions
Put input channels into clearer context.
These questions focus on the origin of information, not on selecting a specific technology.
What is an input channel?
An input channel is a path through which data and metadata enter an information flow. What matters is which information arrives there and in which structure.
Why can input data differ?
Data and metadata can differ in structure, naming, completeness or context. These differences are made visible before central preparation.
What role does metadata play?
Metadata gives data additional context. Reviewing inputs therefore includes identifying which metadata is available and how it is intended to be used.
What follows the capture of input channels?
A structured view of inputs provides a basis for normalising differences and preparing information for receiving systems.
When does reviewing input channels become relevant?
It becomes relevant when origin, structure, naming or context varies across channels and the meaning of the data cannot be derived from the target system alone. Reviewing the channels together makes those differences visible before normalisation.
