Seamless integration between the ORM framework and the mysql database. ORMNow let's talk about in-depth database operations.As we all know, if you use native database statements to write data, you have to repeat the code in a crazy way first, and basically do not reuse the data. They are all written once, and you need to write again later, in this case, the core of object programming is to teach you how to face object databases. In this case, let's lo

　　Java programming is unavoidable to deal with the database, so how to operate the database efficiently and conveniently, but also a need for the problem, the native JDBC-based approach is of course very inefficient, and to write a lot of useless template code, not worth selecting.

Object-Oriented Design, ORM, and nhib.pdf) The ORM design is actually an O-to-D process, that is, the data entity is finally generated by the object. however, the problem is that in traditional design, we must design a Business Object and re-design a relational object (or other storage objects, of course). This method is actually two skins, this is a repetitive process. however, since there is no object-ori

The past few days have been quite lively. Recently, new books have been idle for the final stage, so I have come to join in.

not many scenarios for page caching and query caching. However, object caching is the most widely used in all cache technologies. For any OLTP application, you can also use Object Caching even if real-time requirements are high, and it is a good ORM implementation, the object cache is completely transparent and does not require hard coding of your program code.How to Use object caching without using object caching is not a matter of tuning skills, bu

Origin: At most, you have to write a small thing. For the data persistence layer, I want to use Orm. I was going to select a ready-made framework to complete my little things. However, most of the ready-made ORM frameworks have high learning costs and are complicated, which is not suitable for a small project. Later I saw a friend's datarabbit In the garden. Let's look at the example.CodeIt's pretty good,
