| Abstract: The storage and application of seismic waveform data is one of the important business in National Earthquake Data Disaster Recovery Center.The paper mainly aimed at some questions,which include data storage discrete,low querying efficiency,etc,exist in massive seismic waveform data storage base on traditional relational database and file system, proposed the seismic waveform data storage solution based on Hadoop from the perspective of big data platform, and emphatically describes the business requirements,functional design and principle.We hope to provide useful reference for the construction of the National Earthquake Data Disaster Recovery Center’s data storage platform. |
