Message from the Conference Chairs

We welcome you to participate in ACM SIGAda's annual international conference on Ada Technology, SIGAda '98, in Washington DC, November 8-12, 1998. As the successor to the TRI-Ada conference and Exposition, SIGAda '98 will be this year's largest Ada-focused conference, and continues TRI-Ada's tradition as the meeting place for practitioners, educators and researchers interested in Ada technology.

Ada's proven track record and its full support for object-oriented design and programming makes it a viable language for a diverse number of applications. The installed base of Ada software continues to grow, and this growth is coming in a variety of domains.

It is well known that Ada is the preferred language for high-integrity software-based systems, including aerospace, commercial aviation, and military systems. Less heavily publicized is the significant degree to which Ada is being adopted in ground transportation, financial, medical and internet applications.

The theme of this year's conference, "Ada in Context," focuses on the expanding application of Ada in software development, highlighting that Ada is alive and well in all these contexts. Ada's well estabished support for sound software engineering also makes it an ideal language for introducing software engineering at undergraduate and graduate levels, and as such is of increasing interest to academia.

The conference includes tutorials, technical papers, experience reports, panels, and workshops on a wide range of topics, providing a wealth of information of interest to the Ada community. We look forward to your joining us this November in Washington DC for SIGAda '98!
