Abstract The CMS experiment relies on its Detector Control System (DCS) to monitor and control over 10 million channels, ensuring a safe and operable detector that is ready to take physics data. The data is archived in the CMS Oracle conditions database, which is accessed by operators, trigger and data acquisition systems. In the upcoming extended year-end technical stop of 2023/2024, the CMS DCS software will be upgraded to the latest WinCC-OA release, which will utilise the SQLite database and the Next Generation Archiver (NGA), replacing the current Raima database and RDB manager. Taking advantage of this opportunity, CMS has developed its own version of the NGA backend to improve its DCS database interface. This paper presents the CMS DCS NGA backend design and mechanism to improve the efficiency of the read-and-write data flow. This is achieved by simplifying the current Oracle conditions schema and introducing a new caching mechanism. The proposed backend will enable faster data access and retrieval, ultimately improving the overall performance of the CMS DCS.
