manager of the Project tracks software costs, schedules, and functions, and identifies issues that arise during the performance of the commitment. Create software requirements and baseline for work products that meet these requirements, and control their integrity. After defining software project standards, the organization ensures that these standards are fully implemented. If a subcontractor exists, the software project can work with the subcontractor to establish a strong customer supplier r

()){ Student student = (Student) iter. next (); System. out. println (student. getName ()); Iterate has n + 1 problems when no cache is used. The first iterate query will issue N + 1 SQL statement. The first SQL statement queries all IDs, and then queries the object based on the id. If there are N IDs, it will issue N statements to query objects. Iterate queries different attributes. The first-level cache

Hibernate. In the following example, what about the new Session? In the system, when multi-thread concurrency occurs, more than one Session will be generated. Therefore, when optimization performance is achieved, the first-level buffer will not meet the requirements, so there will be a second-level buffer. For example, the following code clearly sends two SQL

principle of caching is that when the CPU needs to read a piece of data, it first looks for it from the cache. if it finds it, it immediately reads it and sends it to the CPU for processing. If it does not, it reads data from the memory at a relatively slow speed and sends it to the CPU for processing. At the same time, it transfers the data block of the data to the cache, this allows you to read the entire block of data from the cache without calling the memory. This reading mechanism makes t

As a very popular CMS website system in China, DEDECMS is favored by the majority of webmasters. Many people use DEDE to build websites. When using dede to build a website, some functions need to be changed or called according to your preferences. In dede's official documentation, there is no specific description about how to call the first-level and second-level
