What is the purpose of having a common data model (CDM)?

The purpose of having a common data model (CDM) centers around the ability to provide a unified format for data communication among applications. This approach ensures that disparate systems and applications can effectively understand and process the same data, leading to improved interoperability and reduced friction in data exchange. When various applications use a common data model, they can easily share information, reducing the likelihood of miscommunication or data interpretation errors.

Implementing a CDM streamlines integration efforts, as it standardizes how data is structured and formatted, allowing developers to focus on connecting systems without the added complexity of differing data formats. This standardized approach supports the agility and efficiency needed in modern application ecosystems, where the integration of diverse services and platforms is commonplace.

While simplifying data storage, defining data types for individual applications, and eliminating the need for transformations may provide certain advantages in specific contexts, these do not encapsulate the overarching primary aim of a CDM, which is centered on ensuring seamless communication among various applications.
