the source of the high value, the default table is Hibernate_unique_key, and the default field is Next_hi. It divides the source of the ID into two parts, db+ the memory, and then generates the ID value together by the algorithm, can produce many records in the few connection times, improves the efficiencyMysql:create table Hi_value (Next_hi integer NOT NULL);Insert into Hi_value (Next_hi) values (1);4, nativeDepending on the ability of the underlying database, choosing one from identity, seque

In order to meet the higher requirements of users, the firewall architecture has experienced the transition from low performance x86, PPC software firewall to high-performance hardware firewall, and gradually to not only meet the high performance, but also need to support more business capability direction development. After several years of prosperity, the firewall has formed many types of architectures, and the devices of these architectures complement each other and continue to evolve and up

Random There are many ways to generate random numbers using the Java 2 SDK base Class library. But if you can't keep up with the updates to these libraries, you might be using an inefficient random-number generation mechanism, and worse: You might not get random numbers that are evenly distributed. This article will show you a more reliable method of random number generation, while comparing it with other m

Asp+|js A complex form here is a form that contains many different types of input, such as a drop-down list box, a single line of text, multi-line text, numeric values, and so on. There is a need to have a dynamic build program for a form when you often need to replace such forms. This article is about a system that uses a database to save forms to define data, to dynamically generate form HTML code with ASP scripts, and to validate form input scripts. 　　Definition of database table structure Fo
