Data Services Server

Resource Description Framework is the latest model for data interchange and data linking on the web, and it is highly used in semantic web activities. Therefore, it is very crucial to have your data available as a service as RDF resources. In this tutorial I am going to explain how to expose your data as RDF resources in the cloud space using WSO2 Stratos Data Services Server.

Data choices in enterprise solutions were a simple process for many years. The common response was often the use of “H2, MySQL, or Oracle based on expected load and the budget”. However currently this state of affairs has changed with the NoSQL movement. At present there are 100+ storage solutions each with seemingly compelling reasons to be around.

The webinar will present the WSO2 perspective of the problem and provide clarifications with the use of WSO2’s Data solutions.

The applications in an SOA handle different types of data, each with its own access patterns, structure, lifecycle, archival needs, and other attributes and behaviors. As a result, choosing the right storage mechanism can significantly affect the ultimate performance and success of an application. Relational databases have been the traditional choice of storage for enterprise applications. However, cloud computing and Internet-based applications—with their elastic and scalable resources and exponentially growing numbers of users—have been pushed to find more efficient and scalable architectures. These demands are the shot of adrenaline behind the NoSQL (Not Only SQL) database movement. In his presentation at WSO2Con 2011, Sumedha explored the choices available when selecting a data storage engine, the trade offs, factors to consider when making a choice, and examples of different use cases. Here are highlights from his talk.

With over 10 years industry experience in Java, J2EE and database technologies, Sumedha is an Architect and Senior Manager at WSO2. He initiated the award winning WSO2 Data Services Server product and has also contributed heavily to WSO2′s Governance Registry, Application Server, BAM, and Carbon platform products. He is also a Apache Committer of Apache Axis2. Interested in emerging data storage techniques and its application to distributed computing, Sumedha is actively involved in onsite client engagements and defining solutions. Sumedha holds a B.Sc in MIS from the National University of Ireland.

Relational Databases (RDBMS) have historically been the “one size fits all solution” for most data storage problems. But today, with data growing at an explosive rate, data processing systems have had to scale and Relational Databases have failed to handle the task at hand. As an alternative, the NoSQL movement has grown.

The SOA efforts of an enterprise mainly focus on integrating disparate systems. Behind most of these application silos are heterogeneous data stores. WSO2 Data Services Server augments such SOA development efforts by providing a wizard driven approach to expose these data silos as SOA style services or REST style resources. This assures ready access to enterprise data scattered across heterogeneous data sources in a unified manner.

The CableGate affair has shown that even classified systems can have huge Governance and security issues. One reaction to this is to focus on removing CD drives from classified systems. Here at WSO2 we think that the "fix" for these kind of issues goes much deeper: Fundamentally, some of the blame for CableGate must lie with the system design that allowed too many people to access classified and confidential data.

Building web services with SOA (Service Oriented Architecture) best practices in mind has become a preferred approach in the web services arena. The ability to design applications with a flexible set of design principles and loosely integrated services has become a popular method of building Web Services.
