ES3 provides custom database applications for specific businesses as well as products with an expanding base of users through continued product sales. As with all ES3 software, our database application software is well-engineered by a staff of highly skilled and disciplined software engineers. Our custom applications as well as our product lines are robust, highly maintainable, and highly supportable.

ES3 has extensive experience in the design and implementation of large, transaction-intensive applications that must meet customer requirements for performance and data integrity. Our engineering staff is trained, skilled, and experienced in:

• Oracle,
• Sybase,
• Access,
• SQL Server, and
• Informix.

We are experienced in a variety of database query constructs from which we choose the best for our client’s specific applications. These include:

• PL/SQL,
• ODBC,
• JDBC,
• Java DBC, and
• MS JET.

Our preferred languages for developing user intuitive graphical user interfaces (GUI’s) are the following:

• C++,
• Java,

However, we have used developer tool kits when requested by customers who have a preference and want to take over further software enhancements and software maintenance after initial delivery of the system. These tools include:

• Visual Basic
• Delphi, and
• Borland C++ Builder.

Athough ES3 can provide continued software maintenance and support, we are very proud that many of our database applications customers take delivery of our database software applications we have written and provide their own user technical support. We believe this is the best testimony that ES3 delivers database application software that is well-engineered and highly supportable.

One example of ES3’s database application software is the CASA’s adult continuing educational testing software. This software performs the pre- and post-testing of adult students enrolled in educational programs to improve general literacy and math skills. Today, adult education programs in California, Connecticut, and Oregon have purchased or licensed the ES3 software to test their adult students. The ES3 software quickly computes and returns metric data to the teachers and program administrators about the student’s improvement, comparing pre- and post-test scores and tracking student performance against student body demographics. Shown is a sample screen of the ES3 developed CASAS adult student testing software.
