. Security Templates Security templates using the Microsoft Management Console's security Templates snap-in, you can create security policies for your computer or your network. It is a single point of entry that takes into account the overall system-wide security. The security Templates snap-in does not introduce new security parameters, it simply organizes all existing security attributes together to facil

In our previous article, "Using the platform interface provided by Ubuntu-app-platform to reduce QT application Size", we have learned how to use platform interface to reduce the size of QT applications. The implementation of this principle is to use content sharing to achieve. In today's tutorial, we use a Python interpreter snap installation package developed by developers themselves to achieve the same thing. For some systems, if you want to use th

Although located on the same computer, the "Companyserver", "Marketing", and "human resources" all look like unique Web sites. These departmental sites have the same security options as if they were on a stand-alone computer, because each site has its own access and administrative permission settings. In addition, administrative tasks can be assigned to members of each department. For more

mechanism in the second chapter, Snap-connectionpool (a simple and fast connection pooling tool, which can be downloaded in www.snapbug.net), realizes the effective management function of the connection pool to the database resource according to the JDBC specification of the part. 3.1 System Description In the JDBC specification, resources are applied directly to the method database through the driver interface (Driver Interface). In order to manag

the availability of the database's own JDBC driver. The JDBC driver of some databases does not support the logical connection between connection and statement. For example, sqlserver, we can only wait for her own updated version. The application, release, recovery, sharing and synchronization of resources are complex and precise. Therefore, another function of connectionpool is to encapsulate these operations to provide simple calling interfaces for applications without changing the application

At the beginning of this section, it is pointed out that resource depletion is related to the direct management of applications.The optimal management of resources relies heavily on the availability of the database's own JDBC Driver. The JDBC Driver of some databases does not support the logical Connection between Connection and Statement. For example, SQLServer, we can only wait for her own updated

In order to maintain the consistency of the database system, the basic data tables for the whole administrative area should be consistent, and it is difficult t
