PVLng - PhotoVoltaic Logger new generation

A logging and data warehouse system for measuring data of sensors and photovoltaic plants.

The system acts basely as a data warehouse.

In computing, a data warehouse (DW, DWH), or an enterprise data warehouse (EDW), is a database used for reporting and data analysis. Integrating data from one or more disparate sources creates a central repository of data, a data warehouse (DW). Data warehouses store current and historical data and are used for creating trending reports for senior management reporting such as annual and quarterly comparisons. Wikipedia:Data warehouse

All data will be stored in an very simple and efficient internal structure (readings), optimized for data readout of any kind with a well defined API interface.
