Method and apparatus for analyzing data table
A method including calculating processing cost data of the general data table of the data common layer; determining a general data table on which the external data table of the non-data common layer is dependent; and calculating use cost data of the external data table according to the processing cost data of the general data table. In evaluation of the cost of each general data table of the data common layer, instead of taking into account the storage and computation consumption of the current data table in isolation, several upstream data tables and multiple siblings of the data table are also taken into account comprehensively. The processing cost of the general data table is reasonably and accurately assessed, thus reflecting the advantages and disadvantages of data model construction of the data common layer, and providing decision-making support for the optimization and operation of the models of the data common layer.
