Data Services offer a convenient mechanism to configure a Web service interface for data stored in data sources. Data sources such as relational databases, CSV files, Microsoft Excel files and Google spread sheets can be easily service-enabled using Data Services. The data can be exposed and accessed in a secured (using WS-Security) and reliable (using WS-ReliableMessaging) manner, and is also available for mash-up with other Web services.
WSO2 Data Services features can be installed to any WSO2 Carbon-based product. Also, they are shipped as a separate product by the name WSO2 Data Services Server, which can be download from here. Data Services features are added to the WSO2 Application Server by default since it is easier to manage all kinds of Web Services (Axis2, JAX-WS, Data Services etc.) in a single server. Also, it's a common use case in production systems to run Axis2 services together with Data services. The user has the option to use Data Services features in the WSO2 Application Server or use the WSO2 Data Services Server separately, depending on the specific requirements.
