Cache management method of distributed internal memory column database

ActiveCN106294772AReduce calculations for repetitive tasksReduce query timeSpecial data processing applicationsExecution planDistributed memory
The invention discloses a cache management method of a distributed internal memory column database. The cache management method comprises the steps that cache queues are established on cache master control nodes; each physical task is used as a root node to cut the physical execution plan the node is located so as to obtain the cache calculation track corresponding to each physical task; cache feature trees are established on the cache master control nodes according to the cache calculation track corresponding to each physical task; when query requests arrive, an execution engine is queries to parse SOL statements into the physical execution plans; layer-level transversal is conducted on each node in the physical execution plans starting from the root nodes of the physical execution plan to execute, and whether the cache calculation track corresponding to each physical task is matched with the corresponding cache feature tree or not is judged; if yes, actual cache data of the physical tasks is directly read from the cache nodes, if not, the physical tasks are calculated. According to the cache management method of a distributed internal memory column database, weather a cache hits the target or not is rapidly detected through an efficient cache matching algorithm, and the query efficiency is improved.

Traditional Chinese medicine compatibility auxiliary decision-making method based on correlation analysis

The invention discloses a traditional Chinese medicine compatibility auxiliary decision-making method based on correlation analysis. The method comprises the following steps: grouping prescription data into different prescription data subsets according to traditional Chinese medicine diagnosis disease description words, discovering a core medicine group set of each prescription data subset throughcorrelation analysis, and forming an association table of diseases and the core medicine group sets; obtaining a core medicine group set corresponding to the disease from the association table according to a traditional Chinese medicine diagnosis disease description word input by a doctor; recommending the core medicine group set as a first entry template to the user; selecting a core medicine group from the first entry template; generating all possible compatibility sets except medicines contained in the core drug group in the prescription data subset to form a non-core drug group set, counting confidence coefficients of the non-core drug group set relative to the core drug group, sorting the non-core drug group set according to the confidence coefficients, and taking the sorted non-coredrug group set as a second entry template for the user to select and input; and regularly updating the association table of the disease and the core drug group set.
