关于案件矩阵平台，技术开发者拉尔夫•赫克斯特登（Ralph Hecksteden）提供了以下信息（网站使用开源组件）：
| Function | Applied software |
|---|---|
Webserver | Apache |
Database | MySQL (default) Oracle 10g (optional) |
Scripting language | PHP |
Proprietary Case Matrix scripts | |
The following standards are applicable:
| Standard | URL |
|---|---|
HTML / XHTML | |
HTTP 1.1 | |
CSS 2.0 | |
Unicode |
The above-mentioned software is packed into a setup file which allows the out-of-box installation of the Case Matrix runtime environment.
Hardware: Minimum hardware requirements are a X 86 compatible computer with a 2GHz processor, 1 GB RAM and 2 GB hard disk space. No hardware will be distributed with this software.
Data communications: The Case Matrix is a web application. Therefore it uses HTTP for data transmission and it is necessary to have a TCP/IP network available.
Software: As a web application the Case Matrix is addressed over a network such as the Internet or an intranet. The application dynamically generates a series of web documents in a standard format supported by common browsers (HTML/XHTML). Client-side JavaScript is included to add dynamic elements to the user interface.
A significant advantage of the application is its HTML compatibility. This feature ensures the correct functioning of the Case Matrix regardless of the operating system or OS version installed on a given client. Consequently it will not be necessary to create different clients for MS Windows, Mac OS X, GNU/Linux, and other operating systems but the application is developed once and can be deployed in almost every software environment.
The Case Matrix consists of two parts: The XAMPP runtime environment and program logic which is realized in PHP, JavaScript and HTML.
XAMPP runtime environment: The XAMPP platform is a pre-compiled set of open source software. It includes the webserver, the database and support for the scripting language. XAMPP stands for:
X = Windows or Linux
A = Apache web server
M = MySQL database
P = PHP scripting language
(P = Perl scripting language (not used))
Apache: The Apache HTTP Server, commonly referred to simply as Apache, is a web server. Apache is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation. The application is available for a wide variety of operating systems including Microsoft Windows, Novell NetWare and Unix-like operating systems such as Linux and Mac OS X. Released under the Apache License, Apache is free and open source software.
MySQL: MySQL is a multi-threaded, multi-user SQL database management system which has been developed by MySQL AB, Sweden. The company develops and maintains the system, selling support and service contracts, as well as proprietary-licensed copies of MySQL. The MySQL AB makes MySQL Server available as free software under the GNU General Public License (GPL), but they also offer the MySQL Enterprise subscription for business users and dual-license it under traditional proprietary licensing arrangements for cases where the intended use is incompatible with the GPL.
PHP: PHP is a reflective programming language originally designed for producing dynamic web pages. PHP generally runs on a web server, taking PHP code as its input and creating Web pages as output, however it can also be used for command-line scripting and client-side GUI applications. PHP can be deployed on most web servers and on almost every operating system and platform free of charge. The PHP Group also provides the complete source code for users to build, customize and extend for their own use. The runtime environment of the Case Matrix Database includes PHP 5.1.2. as default PHP version.
