eWave places great importance on both knowledge preservation and the effort inherent in organizations’ existing internal systems. Because of this, we specialize in integrating legacy applications within enterprise systems. We implement several system preservation methods: using existing software modules such as Web Services, developing modules based on existing organizational systems, and customizing "green screens" to work with Web browsers.

Most of eWave's projects involve integration with at least one existing system, and many involve complex integration with multiple systems. A successful integration project can save costs while taking advantage of existing systems and improving the quality of service provided to end users. Integration prevents data duplication, synchronization problems, and repeated password entry.
