The invention provides a multi-source heterogeneous
water environment big data management system, and relates to the technical field of computers. The
system comprises a
water environment big data cleaning unit for cleaning
water environment data, a water environment
big data exchange unit for exchanging the cleaned water environment data, and a
metadata management unit which is used for tracking and analyzing the water environment big data. On the one hand, by establishing the water environment data cleaning model, the cleaning process and the cleaning rule are provided, and the problem of conflicts during water environment
data application is solved; on the other hand, a distributed technology is adopted at the center end of the
data exchange platform, an
NoSQL database and a
relational database are supported, the type of stored data is effectively expanded, and the data reading and writing efficiency is improved; besides, by defining the
metadata of the water environment big data, unified coding, management and retrieval of the
metadata in the multi-source heterogeneous water
environment management system are realized, and a metadata support is provided for the
management system.
