DATA IMPORT SYSTEM FOR DATA ANALYSIS SYSTEM

摘要

A data import system (100) enables access to data of multiple data sources of different formats (201-302) and provides an interface for importing data (200) into a data analysis system (210). The interface (205) enables a user to customize the formatting of the data as the data is being imported (200) into a data analysis system (210). A user may select first user defined options (410) for operating on a first data set received during a data importation process (200). An intermediate representation of the data set (204) is generated based on the user first defined options (410). A user may specify second user defined options (410) based on the intermediate representation (204) during the data importation process (200). The second user defined options (410) are processed to produce a final data representation (208) of the data set to be used for analysis of the data. The intermediate representation may be a data table (204). The processing of a data set may include merging a first and second data set (206) to produce the final data representation (208). The second user defined options (410) may enable a user to select a basic operation for merging (206) the data sets or to select a non-basic operation for merging (206) the data sets. The basic operation may combine data sets in response to a user's selection of a first graphical interface control (520, 550), and the non-basic operation may combine the data sets based on user selection of at least two graphical interface controls (510, 530, 540) from a group of graphical interface controls.
