Diagrammatic Programming Interface for Graph Traversal Algorithms

Sammanfattning: Graph databases are a modern and efficient way of dealing with large amounts of interrelated data. The company provides a software platform that collects, documents and visualizes data for a large variety of businesses. With a new major update in the works, the company proposed a new feature in the product which will be used by both in-house developers and customers alike. There is a need for a user-friendly interface for the design and construction of graph traversal algorithms for data retrieval. Designing an interface that is intuitive and efficient for developers and end-users puts high demands on the design process to understand a variety of user groups. The main challenge consisted of abstracting domain specific terminology into a more general model. By applying a variety of user-centered design methods a solution was developed and evaluated. Using a node-based programming interface proved to be a viable approach for construction of graph traversal algorithms.
