about Hibernate:Hibernate is an open source framework, which is a framework for object-relational mapping, and it is a lightweight encapsulation of JDBC, and our Java programmers can manipulate the database using object-oriented thinking.Hibernate Core InterfaceSession: Responsible for persistent object CRUD operationsSessionfactory: Responsible for initializing hibernate, creating Session ObjectConfiguration: Responsible for configuring and starting hibernate, creating sessionfactoryTransaction

The nature of the shell The shell of the Linux system is equivalent to the "one shell" of the operating system, which is the command language interpreter, which provides the user with an interface to use the operating system. It does not belong to the kernel, but is run as a user state outside the kernel. Its basic function is to interpret and execute the various commands that the user has entered to implement the interface between the user and the Linux kernel.Personal understanding: The shel

);,clearTimeout(id); -接受一个计时器ID（由之前两种计时器返回）并且停止计时器回调函数的执行。 To understand the inner workings of the timer, we first need to understand a very important concept: Timer set delay is not guaranteed. Because all JavaScript single-threaded asynchronous events (such as mouse click events and timers) executed in the browser are only executed when it is empty. This is best illustrated by a picture, as shown in the following diagram:There's a lot of information in this picture that needs to be digest

1."Reference count (reference counting)" is a simple but slow garbage collection technique. Each object contains a reference register, and when a reference is connected to an object, the reference count is added by 1. When the reference leaves the scope or is set to NULL, the reference count is reduced by 1. Although the overhead of managing reference counts is small, it requires continuous overhead throughout the program life cycle. The garbage collector iterates over the list of all objects, r

"Listen to Wind yi Xue" This group of films is imitation of the Chinese classical wind of the late, a lot of friends think I am mostly painted, in fact, I have never used to repair pictures of the drawing board, or even the mouse, with just an IBM General notebook computer, IBM has a red navigation button, the point is not bad, with the habit of no mouse can repair the picture. Gossip less and say, the shooting of this group of works is actually under

I don't know what's going on lately. About the ancient Chinese color and flowers, scenery combined with the theme of the works, and a wonderful article, almost every day of the ecological home page will have this theme works, many people seek to shoot this kind of work tutorials and post-production skills? So I started this article-- Give a little reference to the novice who wants to shoot this kind of subj

The work is the best way to show personal talent, such as design, photography, these creative careers need to have a personal portfolio site, so that you can display yourself in a personalized way and present your work to readers and potential customers. At the same time, the excellent design works and tutorials assembled in these sites are also good sources of inspiration for others. Today, this article with you to share 20 pieces of beautifully craf

creates another data structure that contains the value of the field and a pointer to the related record, and then sorts the index structure to allow the binary ordering of the data. The side effect is that the index requires additional disk space, and for the MyISAM engine, these indexes are uniformly stored in a single table, which will quickly reach the size limits that the underlying filesystem can support, if many fields are indexed. How indexing works
