OBJECTIVE: to develop a prototype of a Colorectal Cancer records management system, aiming to store an embracing structured dataset for later application of intelligent data analysis methods. MATERIAL AND METHOD: the prototype was developed in five stages: Colorectal Cancer domain analysis, definition of basic requirements (operational and informational), system design, system construction using open source technologies and system evaluation supported by domain experts. RESULTS AND DISCUSSION: during development, the prototype dataset structure, coherence of information structure, validity of functions implemented and the attendance to the basic requirements define, were evaluated by domain experts. CONCLUSION: according to the experts evaluation, the prototype development completed the first stage of the project of developing the system with a 100% satisfaction rate and is now being used into recording real data. In the next stage it will be finished and deployed the complete system, attending to security requirements and multiuser support
