Software-as-a-service (SaaS) software data model realization method

Abstract

The invention relates to a data management method, in particular to a software-as-a-service (SaaS) software data model realization method. The SaaS software data model realization method is based on the sharing mode of a shared database, and comprises the following steps of: 1, metadata definition, namely, dividing metadata into two types consisting of a data dictionary and spatial data, and identifying the metadata by using a field in a database table; 2, generation of a basic space, namely, collecting universal data to form the basic space; 3, generation of each new space, namely, filling the basic data of each new space, copying data from the basic space into a current space and simultaneously sharing the data of the data dictionary; and 4, cross-space use of a single user, namely, registering each user into at least one space, accessing all registered spaces after the login of the user, and judging the identification field of the spatial data to enable the user to view current spatial data.

Description

technical field [0001] The invention relates to a data management method, in particular to a method for realizing a SaaS software data model. Background technique [0002] SaaS is the abbreviation of Software-as-a-Service (Software as a Service). It is a mode of providing software through the Internet. Customers do not need to purchase software, but rent Web-based software from providers to manage business activities. .

For many small and medium-sized enterprises, SaaS is the most economical management tool. SaaS reduces the cost and complicated work of building and maintaining infrastructure and applications. [0003] When designing the data model of the SaaS system, in order to serve customers and reduce development costs, it is necessary to strike a certain balance between data sharing and isolation. In addition, when designing the data model, it...

However, since all customers use the same set of data tables, more additional development costs need to be spent on ensuring data security, ensuring that a customer will never access other customers' data due to system exceptions

[0011] The data models of the above three SaaS systems can only be managed on the basis of customers, and cannot undertake the parallel management functions of organizations (enterprises) and individuals. If a person belongs to multiple organizations at the same time, it is impossible for this person to log in with his own account. Ability to see information in all organizations
