Development of Tools for Handling and Monitoring the Condition Data for the CMS Experiment

In this thesis, we describe the needs for the operation of a Database Management System (DBMS) to store and retrieve non-physics data, i.e. those data used for support, configuration, maintenance and monitoring of the detector. The quality and the amount of this kind of data is, by nature, mutable in time. The database services for them must be designed to be flexible enough to accommodate changes in rates and types of data, but overall the database has to be efficient. Data retrieval must not add a consistent amount of time to computing processing (like reconstruction and simulation) which has to be as fast as possible. Given the above requirements, in this doctoral thesis, we will present the contribution given to the development of tools and services for the CMS condition database using the CMS Software framework (CMSSW).
