The approach is different: Back-to-front

The Risaris approach is focused on the use of SOA standards from the back of your technical environment to the front.

The Gateway has been built to unleash the power of legacy data and information across multiple platforms. The approach delivers business and technical benefits.

The SOA Gateway:

• Is single tiered
• Runs local to data
• Interfaces directly with local resources
• Focuses on web services
• Provides platform, database and language coverage.

Single-tiered approach
The Risaris SOA Gateway is a single-tiered approach to expose business logic and data as Web Services by locating the product local to the data and business logic.

Other implementations use two and three tiers to expose data as a Web Service.

Using a single-tiered approach leads to advantages in terms of overall performance and delivery of the Web Services, while reducing the points of failure leading to a more robust Web Services infrastructure.

Runs local to data and business logic
By running entirely local to the data and business logic, the Gateway has the ability to work more closely with the local platform infrastructure.

This leads to improved integration in:

• Security
• Transactionality
• Performance.

Interfaces directly with local resources
The SOA Gateway runs on the local platform to the data and business logic.

It can interface directly with local resources, such as dispatching mechanism, performance monitors and so on.

All the data for measuring performance and identifying problems is in one place. Hence, performance measurement is easier. Dealing with problems is also simpler as there is only one layer and one platform to check when and where problems occur.

Focused on Web Services
The SOA Gateway provides data using Web Services and hence can be optimised based on that protocol standard.

In addition, the SOAP protocol is the basis upon which the EU’s DataGrid project is being built. This will ensure users of the SOA Gateway are ready for the next generation of infrastructure by fitting into the GRID infrastructure seamlessly.

Platform, database and language coverage
The SOA Gateway has been designed as a portable and structured technology. Its main core is C and C++ and thus can be ported to any platform.

Database and language interfaces are built as Data Source Driver plug-ins and can support databases like:

• ADABAS
• VSAM
• DB2
• IMS/DB
• Oracle
• Sybase.

The SOA Gateway supports business logic written in languages such as:

• Natural
• COBOL
• PL/1
• Assembler
• Java
• C#
• PHP.

Please contact us if you have queries on other languages supported.
