<p>The present invention relates to the information processing field. Disclosed are a method and device for storing and retrieving data, so that distributed storage of data requiring full-text retrieval and data not requiring full-text retrieval in the parallel database is implemented, thereby reducing the storage redundancy; meanwhile, the full-text retrieval and structured retrieval of the data to be retrieved are implemented in the parallel database, thereby improving the retrieval efficiency. The present invention comprises: a control node, in a parallel database system architecture, storing data requiring full-text retrieval and data not requiring full-text retrieval on different types of data nodes respectively; according to a retrieval request sent from a client, sending different types of retrieval instructions to different types of data nodes, so that a retrieval execution node can simultaneously execute, according to different retrieval execution instructions, different types of retrieval operations on the data to be retrieved. Embodiments of the present invention are mainly applicable to data storage and retrieval processes.</p> |
