Metadata-driven visual SaaS (Software as a Service) application customizing method and metadata-driven visual SaaS application customizing system

Abstract

The invention relates to a metadata-driven visual SaaS (Software as a Service) application customizing method and a metadata-driven visual SaaS application customizing system, which can be used for flexibly supporting SaaS application customizing types and extension within the customizing types. The method includes the steps: A, renting an application and building a business system by a tenant; B, customizing the business system and selecting customizing types and objects by the tenant; C, initializing the visual SaaS application customizing system according to the customizing types; D, reading the content of metadata customized by the tenant and displaying the customized metadata on a customizing operation interface in the form of visual elements by means of translation and analysis by the visual SaaS application customizing system; E, customizing the elements on a visual customizing interface by the tenant according to the demand of the tenant; F, judging whether the operation of customizing the elements by the tenant is allowed or not and correcting visual customizing data by the visual SaaS application customizing system, and writing back the customized metadata when storing the data after customizing by the tenant; G, executing issue operations by the visual SaaS application customizing system while writing back the metadata so that customizing becomes effective; and H, logging in the business system by a user to see the business system customized by the tenant.

Description

technical field [0001] The invention relates to the field of software development, in particular to a method and system for visual customization of SaaS applications driven by metadata. Background technique [0002] In the traditional mode, developers need to develop and deploy applications according to the needs of different customers, and the cost is high. The SaaS model has changed the traditional software business 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. As a standard application, the application submitted by the developer is not suitable for the needs of each tenant, and the needs of the tenants will change over time. Therefore, in order to meet the personalized business needs of different tenants, SaaS applications must support "tenant Customize". The application involves multiple levels such as interface, service, and data, forming customi...

Problems solved by technology

[0003] Analyzing the flexible customization requirements of SaaS applications has the following characteristics: First, SaaS applications have many aspects that can be customized, such as page customization, function customization, data customization, etc. Although these customization types have different requirements, they are more complicated to implement individually. New requirements need to be re-implemented again, which limits the customization type and the internal scalability of the customization type; secondly, the complexity of customization implementation affects the customization efficiency and promotion difficulty of tenants. Hiding the underlying implementation details is the key to solving the problem; thirdly, to meet the isolation requirements of tenants, tenants can only see their own data during customization and runtime; finally, to ensure that tenants do not violate the requirements of the business system when customizing on demand Intrinsic logic, it is necessary to limit the customization operations of tenants on customized content
