Core technology, high-level overview. The ArrayPlex server is a nearly encapsulated system composed of an embedded Java Runtime Environment and Apache Tomcat application server. The ArrayPlex server requires one external resource, a PostgreSQL relational database server. The ArrayPlex server and PostgreSQL database need not operate on the same computer. The ArrayPlex server operates within the Linux operating system and communicates with the PostgreSQL server by the standard JDBC protocol. The ArrayPlex client can be operated on any Mac OS X, Windows, or Linux computer. The ArrayPlex client is not installed but rather launched through use of Java Web Start, ensuring that the client is always up-to-date when used on any computer. The ArrayPlex client communicates with the ArrayPlex server by HTTP.
