基于查询需求自适应地从当前时间的行存储数据库中构建列存储数据库的方法和系统
Abstract:
一种从行存储数据库中动态构建列存储数据库的方法。所述方法包括：构建存储数据的行存储数据库，其中，每行包括多个属性，且行存储数据库中的数据相对于当前时间点是最新的。所述方法包括：构建列存储数据库，其包括为满足接收到的分析查询而构造的数据。所述方法包括：从列存储数据库的初始状态开始，对于每个后续接收的分析查询，将目标量数据从处于对应当前时间状态下的行存储数据库导入到列存储数据库中，以满足相应的后续接收的分析查询。
Abstract(English):

A method for dynamically building a column store database from a row store database. The method includes establishing the row store database for storing data, wherein each row includes a plurality of attributes, and wherein data in row store database is current to a temporal point in time. The method includes establishing the column store database including data structured to satisfy received analytic queries. The method includes beginning from an initial state of the column store database, for each subsequently received analytic query, importing a targeted amount of data from a corresponding temporal state of the row store database into the column store database to satisfy the corresponding subsequently received analytic query.
