Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0051] The present invention processes the deleted records in the source system by "closing the chain", that is, sets the end date (End_Dt) of the corresponding record as the current batch date, indicating that the validity period of the record ends on that day, and realizes the full source of the current day. The data is loaded into the data warehouse and saved in the form of historical zippers to meet the data warehouse's demand for full source data to retain historical traces.

[0052] Such as figure 2 as shown, figure 2 It is a structural schematic diagram of the device for extracting, transforming and loading the full amount of source data provided by the present invention. The device includes a data receiving uni...

Abstract

The invention discloses a device and a method for extracting, converting and loading gross source data. The device comprises a data receiving unit, a data processing unit, a data export unit and a database, wherein the database is provided with a temporary working area and a foundation area; the foundation area of the database is provided with an object list inside; the data receiving unit is connected with the database and used for receiving gross source data files from a source system and loading the gross source data files into the temporary working area of the database; the data processing unit is connected with the database and used for extracting, converting and loading the gross source data files which are loaded into the temporary working area of the database and storing the processed gross source data into the database in the mode of historical chains; and the data export unit is connected with the database and used for exporting the gross source data which is stored into the database for other systems to use. The invention meets the requirement of the database on the reservation of historical track of the gross source data.

Description

technical field [0001] The invention relates to the technical field of database source data processing, in particular to a device and method for extracting, converting and loading full source data. Background technique [0002] For the enterprise data warehouse (EDW), its most basic function is to extract, transform and load the data from the business source system according to certain rules (ie Extract, Transform and Load, ETL). Due to the diversity of source systems, the data from source systems are also varied, and cannot be extracted and transformed with a single rule. Enterprise-level data warehouse is to transform data with different attributes and changing rules into standardized data information that meets certain rules and conforms to database-related paradigms. It is very important for enterprises. Especially for large state-owned commercial banks, due to the massive amount of data, how to extract and organize this massive data into a complete set of orderly and ...
