The permission system has two concepts: Coarse granularity:Indicates the class (model) level, that is, only the type of the object is considered, not a specific instance of the object. For example, in the management of the contract category (contract), creation, deletion, and other operations, all users are treated equally without distinguishing specific object instances (sales contracts and production contracts ). Fine Granularity:It indicates the i

How can this interface be filtered out in the current permission system?Bingyun @ not in the status:Well, it depends on your connection method.Bingyun @ not in the status:If it is a small granularity, make a facade, for example, my validate (user, resource, operation)Bingyun @ not in the status:For a large granularity, give a webservice or something like that,Bingyun @ not in the status:The premise is that,Bingyun @ not in the status:Role, resource, and operation can be uniquely ide

between users and roles is one-to-many. I want to know what is necessary to set a one-to-many relationship?Isn't one-to-one relationship better handled? In my understanding, a user can have multiple roles. Yes: One person can have multiple rolesA role can also be used by multiple users.A multi-to-many relationship usually requires an intermediate table to be mapped. Unless you are using a redis non-relational database Not one-to-many, but many-to-many. You may not need a project, but y

Original: Enterprise Management system front-end separation Architecture Design Series one permission model chapterThe previous time with Vue and react wrote two back-end management system Templates Vue-quasar-admin and 3YAdmin. RBAC-based permissions control is implemented in two projects. Because the job is back-end development, it is clear that the authority to control a management system should have the

The classification list specifies which type of classification target object is accessible. During access, the system firstCompare the user's access permission level with the resource object confidentiality level, and then determine whether the user can access the resource object.

In the information system security mechanism, access control is an important mechanism and has many important applications. The access control or permission management system is currently one of the most frequently used modules in computer application systems. In enterprises, almost all different application systems have an independent permission management system. Different permission management systems may have different data storage, permission access, and access control mechanisms. In recent

I encountered some simple basic concepts, but I thought about it and found that I didn't fully understand it. The following is a summary of the Search: 【Abstract]-Generation model: Infinite sample = probability density model = generation model = Prediction-Discriminative model: Finite Sample = Discriminant Function = p

This learning note is from the "Time series analysis-based on R" written by teacher Wang After the preprocessing of a time series, it is shown that the model has the value of extracting information, then the next model is established to make the prediction. Here are three important models for fitting time series. I. AR model The AR (p)

In a Web page, elements have three layout models:1. The flow model, the default, is that block-level elements are distributed from top to bottom, with widths of 100%. Inline elements are horizontally distributed from left to right. 2, floating model (float)Div, p, table, IMG and other elements can be set to float. The code for the two div displays in one line is as follows: div{ width:200px; height:40

To sum up the differences between them, please add: 1. The essential difference between the two is that the modeling objects are different. Suppose there are sample input values (or observed values) x, category tags (or output values) y The evaluation o

The factory method mode encapsulates the creation of objects in a centralized manner. It can be implemented without major changes when changing objects, reducing the coupling between customer programs and product objects, is a further abstraction and promotion of the simple factory model.
