# 2. Introduction

The Vortex OpenSplice Modeler is an integrated Eclipse-based tool chain based on Data Distribution Service (DDS) domain-specific model driven techniques. It provides the essential productivity tools of ADLINK’s third generation OMG-DDS suite.

Vortex OpenSplice is a suite of software products comprised of a high-performance, low-overhead run-time environment, development tools for modeling information and applications, and run-time tools for monitoring system performance.

The Vortex OpenSplice Modeler conforms to the Object Management Group’s (OMG’s) Data Distribution Service for Real-Time Systems Specification for the high-performance, high-integrity systems required in defence, air-traffic control, SCADA, and other applications, where RT distributed data is a requirement for acceptable systems performance.

The Vortex OpenSplice Modeler is designed to provide developers of these RT systems with an easy-to-use, graphical modeling environment that dramatically increases their productivity, and 2nd generation DDS middleware offering superior performance, scalability, robustness, fault-tolerance, flexibility, and ease-of-use.

The objective of the Vortex OpenSplice Modeler is to reduce complexity, shorten time-to-market, raise quality, and ensure Standards compliance and code correctness; all in a single integrated suite of tools from a proven and trusted vendor.

The Vortex OpenSplice Modeler facilitate DDS-based system development by clearly distinguishing between the various scopes and lifecycle stages of the system supported by visual composition, configuration and round-trip engineering. This purpose is realized by the following means:

- Guidance - the tools provide context-aware guidance regarding the overall DDS concept, patterns and best-practices.
- Well-defined hierarchical steps - includes information modeling (topic definitions in IDL, code-generation for topic QoS), application design (code-generation for application frameworks and DDS entities such as publishers/writers, subscribers/readers) and system deployment (information partitioning, network-configuration and durability configuration resulting in XML-based Vortex OpenSplice configuration data).

The Vortex OpenSplice Modeler includes these tools:

- Vortex OpenSplice Information Modeler - graphical information-modeling tool for system-wide Types and Topics.
- Vortex OpenSplice Application Modeler - graphical application-modeling tool for application code-generation based on a DDS meta-model and related palette of DDS-entities and application frameworks, including of DomainParticipants, Publishers, Subscribers, DataWriters, DataReaders and Listeners.

A future release will also include:

- Vortex OpenSplice Deployment Modeler - graphical deployment-control environment supporting real-time connectivity with the deployed target system both for configuration-purposes as well as run-time control and monitoring (by integrating the OpenSplice Tuner features in the Eclipse-based framework).
- Round-trip engineering between the modeling environment and the actual deployed target system.

The Vortex OpenSplice Modeler is currently available for Windows and Linux running Sun’s Java SE JDK 6 and Eclipse 3.6.

The Vortex OpenSplice Modeler product is supplied as profiles: individual, tailored packages specific to each modeling area, including:

- information modeling
- application modeling
- deployment modeling (to be supported in a future release)
