Let me restore my experiment and clarify the relationship in a sequential order.First, the relationship between the role and the user is tested.In PostgreSQL, there are two confusing concepts: roles/Users.

Differences between Oracle sys and system users, sysdba and sysoper system permissions, and sysdba and dba roles Differences between sys and system users 1) The most important difference is that the importance of stored data is different. Base tables and views of all oracle data dictionaries in sys are stored in sys users. These base tables and views are crucial for oracle operation and are maintained by the database, no user can change it manually. S

In the past few days, I have been practicing the musicstore project. But when I create a project role to complete different access permissions on the page, the problem arises, However, the solution has just been solved. The following is a summary: Problem: When creating a project, you certainly do not want all users to access your page at will. Generally, only Administrators can access the page at the background. How can I set this administrator role? Open the project and click "project"> "Asp.n

Now we are just starting an ASP. NET 1.1 project, because one of the customer's requirements is that some user authentication information needs to be integrated with the customer's current ad authentication, the first thing that comes to mind is ASP. NET 2.0 is a very convenient feature, membership, because the Provider Model patterns is used, it is very convenient to insert a Custom User Authentication Mechanism in the system. Why not implement it in ASP. NET 1.1? Then I thought that since memb

Java Dynamic proxy ModeProxy: a role represents another role to implement some specific functions.For example, the relationship between producers, middlemen, and customersCustomers who buy products do not directly deal with producers, nor do they know how the products are produced. Customers only deal with middlemen, and middlemen can carry some packaging on the products, provide some after-sales services. Proxy mode has three roles: 1. Abstract topic

other hand, it also achieves modularization. Of course, it is difficult for an enterprise to implement SAP because its management mode and Business architecture have changed significantly. SAP's common experience is: strengthen communication and communication, and adopt a gradual optimization process. In the beginning, instead of taking the "fierce medicine", we insisted on continuous optimization. As the environment and people's concepts change, it is a kind of spiral upgrading and optimizatio

Introduction: When a new user is created, the user does not have any permissions and cannot perform any operations. If you want to perform a database operation to be determined, you must grant the system permission to it. If you want to access objects in other schemes, you must grant the object permission to it. Roles can be used to simplify permission management. (1) role:A role can be granted system or object permissions.Oracle has defined several

In implementing continuous delivery, we can easily focus on automation and tools, because they are usually the easiest to do as a starting point. However, the successful implementation of continuous delivery also relies on the optimization of the organizational structure based on the final deliverables. For continuous delivery, the biggest obstacle is the organization of teams based on roles and hierarchies, rather than the final deliverables (product

The roles and differences of @RenderBody, @RenderSection, @RenderPage, Html.renderpartial, html.renderaction1.

SYS and SYSTEM user differences 1 The most important difference, the importance of storing data is different SYS the base tables and views of all Oracle's data dictionaries are stored in the SYS user, which is critical to the operation of Oracle and is maintained by the database itself and cannot be manually changed by any user. The SYS user has roles or permissions such as Dba,sysdba,sysoper and is the highest user of Oracle permissions. The system

A role is a collection of permissions. 1. System predefined roles A real database administrator should be the owner of the entire server and its database, with all the permissions to administer the server and its databases. In a large system, the database administrator is often not only one person to bear, but the management of the task of functional division, each mention when different responsibilities.

"common employee ". So I think the "level" here is the concept of a role. "Role" may be required. Question 3: there is a relationship between the user group table and the permission table. Then the "user_right" in systemlogin will no longer work, and there will be conflicts (for the time being, it is only to maintain the old system without errors). Should I delete user_right? Conclusion: we cannot figure out their specific relationships and their repeatability. 2. relationships between individu
