【 摘 要 】

The CMS High Level Trigger (HLT) is a collection of software algorithms that run using an optimized version of the CMS offline reconstruction software. The HLT uses Python configuration files each containing hundreds of modules, organized in sequences and paths. Each configuration usually uses an average of 2200 different modules and more than 400 independent trigger paths. The complexity of the HLT configurations and their large number require the design of a suitable data management system. The work presented here describes the solution designed to manage the considerable number of configurations developed and to assist the editing of new configurations.
