API Design for Architects

Almost every software development project requires communication with other IT systems. A wide range of remoting technologies are available, each with different advantages and disadvantages. The training course will explain the different working methods of the technologies, as well as demonstrate brief examples highlighting the specific characteristics.

You will get to know the most important interface technologies as well as your preferred usage scenarios. Several case studies will demonstrate what is important when choosing the right technology and how this choice affects versioning, usage scenarios, scalability, development effort and other risks.

AD-EAPI

  • Duration

    1  day

  • Goal

    • In this seminar, you will learn the basic functions of various interface technologies within a very short time and will be able to distinguish them from each other.
    • Using examples and case studies, you will gain practical knowledge to find a suitable solution for your project.

    • Target group

      As a project manager, developer or architect, you would like to find out about different ways of exchanging data via networks. You have not yet gained any more in-depth experience with the various technologies and would like to gain an overview in order to be able to use different interface technologies for your projects.
