What is Interoperability?
Interoperability is the ability of different systems to exchange data with common standards.
Definition and Word Origin
The word comes from the Latin roots inter (between) and operate (to work). It is the agreement of two systems written in different languages or with different technologies by speaking a common language. For example, it is thanks to this ability that an accounting program can communicate automatically with bank systems. It enables technologies to form an ecosystem without being dependent on each other.
How to Know and Use in Daily Life?
Accounting and banking: Account transactions are automatically recorded in the program.
Chargers: Thanks to the USB-C standard, many devices can be charged with a single cable.
Smart home: Different brands work in the same house with the Matter standard.
e-Invoice: In Türkiye, companies can send invoices to each other using UBL-TR format.
Technical Depth and Architecture
Interoperability is achieved at the following layers:
Data format: Publicly readable formats such as JSON or XML.
Interface (API): Defined doors that systems open to each other.
Protocol: Rules for how data will be transported (e.g. HTTPS).
Authentication: Who can access what data (e.g. OAuth 2.0).
Versioning: When the interface is changed, the old one works for a while longer.
The rule is simple: the more proprietary formats, the less interoperability.
Use in Different Disciplines
Language: People from different countries communicate with a common language.
Railway: Thanks to the track width standard, trains can change countries.
Electric: Socket and voltage standards make devices compatible.
Questions and answers
Why doesn't every system have this feature?
Sometimes companies keep their systems closed on purpose, and sometimes different technologies are technically incompatible. Choosing an open standard usually pays off in the long run.
How to achieve interoperability?
With open format, documented API, standard protocol and version discipline. For new integration, you need to look at existing standards first.
Is it risky to stick to a single standard?
Locking in a single supplier is risky, leaning on an open standard distributes the risk. Make sure there is a large community behind the standard.
How does it affect security?
Opening a door increases the attack surface. Therefore, the interface should not be opened without authentication, authorization and registration (log).
