Abstract
Description
technical field
[0001] The invention relates to data processing of a data warehouse, in particular to a processing method and system for the process of data extraction, transformation and transfer (ETL) in a data warehouse OLAP system. Background technique
[0002] A data warehouse is a subject-oriented, integrated, time-related, and unmodifiable collection of data in enterprise management and decision-making, that is, for all application systems, such as customer relationship management (CRM, Customer Relationship Management) systems, financial systems, etc. , integrate by topic, and record the entire history of changes. With the continuous improvement of enterprise informatization, a large amount of business data has been accumulated within the enterprise, and the data warehouse system is used to uniformly process these mutually independent and scattered data to meet the needs of high-level decision-making and analysis of the enterprise.
[0003] Referring to Figure 1, it...

Embodiment Construction
[0050] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0051] The core idea of the present invention is: by setting the data synchronization configuration table and the data refresh configuration table, the ETL process of the data warehouse OLAP system adopts a multi-process parallel synchronous refresh mode, and after the synchronous processing waits for the data source to recover, multiple data sources are started to be synchronized Process; refresh processing According to the completion of the synchronization process of the same data object and the refresh scheduling relationship of the data object, multiple refresh processes are started for multiple data objects; synchronization and refresh processing are started at the same time, and the same data object is refreshed in time afte...
