Data engine system supporting SaaS multi-tenant function and working method of data engine system

Abstract

The invention discloses a data engine system supporting the SaaS multi-tenant function and a working method of the data engine system. The data engine system mainly comprises a data access request processing module, a multi-tenant data access module and a multi-tenant metadata access module, wherein the data access request processing module is used for recognizing two user types which comprise a business user type and a support user type; the multi-tenant data access processing module is used for analyzing and recognizing access requests, and performing multi-tenant mapping processing and data safety/privacy processing; the multi-tenant metadata access processing module is used for accessing, storing and updating the pattern description information, the service description metadata information and the service state information of data storage, the pattern description information of custom-made metadata and the like. According to the data engine system and the working method thereof provided by the invention, multi-tenant data customization, storage and query conversion driven by metadata are realized; an efficient index mechanism and a data safety access control mechanism are provided for multiple tenants; basic support is provided for logical view construction of tenants.

Description

technical field [0001] The invention relates to the technical field of data engines, in particular to a data engine system supporting SaaS multi-tenancy and a working method thereof. Background technique [0002] The SaaS model has changed the traditional software delivery model, providing services to different tenants based on the same software instance, that is, "single instance with multiple leases", which is cheap and quickly deployed. For tenants, it supports tenants to rent on demand, which reduces the initial investment cost of tenants, and does not need to care about the maintenance of infrastructure and the complex technical implementation of SaaS applications themselves, and cancels the restrictions of space and location on the use of traditional software. Tenants provide great convenience; for ISVs, the SaaS model means a fundamental change in the way of distributing and deploying software, and in order to cope with this change, ISVs must change their thinking on ...

AI Technical Summary

Problems solved by technology

Traditional software development and delivery models need to consider the characteristics of multi-tenants when developing SaaS applications, and develop an application that can meet the needs of all tenants. This development model greatly increases the technical threshold, increases the development cost of developers, and is not conducive to Rapid Popularization of SaaS Applications

In order to meet the needs of developers to develop standard applications, it is necessary to solve the mapping mechanism between the data model and user view, so that developers do not perceive the difference between multi-tenant data access and independent software data access, which has great impact on the establishment of data storage logic model and Logical mapping mechanism presents challenges
