OData is a standardized protocol for creating and consuming data APIs. OData is based on HTTP and follows the REST architectural style. OData can be seen as the SQL for the web. Stephan will give a quick insight into OData while explaining history, principles and protocol features. Enterprises are facing a dilemma if they want to open or integrate data which is stored in different data containers. Stephan will show how OData can solve this issue. Then Stephan will talk about Apache Olingo which is a Java library supporting a client and server API of an OData protocol implementation. He will conclude the presentation with a demonstration on how easy it is to get an OData service implemented by using Apache Olingo.
