I've been learning hibernate for a while, so let's start with hibernate because of the layered architecture of MVC, the emergence of the data persistence layer (the model layer), the persistence layer is based on the MVC three-tier architecture, and before the persistence layer is presented, Business logic layer in the implementation of business logic, but also need to access the database, so that the expansion of business logic is difficult, with a persistent layer, the business logic layer onl

Object Relational ing (ORM) is a technology designed to solve the mismatch between objects and relational databases. To put it simply, Orm automatically persists the objects in Java programs to relational databases by using metadata describing the ing between objects and databases. In essence, data is converted from one form to another. This also implies additional execution overhead. However, if

1. Moon features ---- All wisdom is simple, but not known. It is also the main feature of Moon. ORM: the greatest truths to simplicity. 1. high performance is Moon. one of the advantages of ORM is also one of the main purposes of my architecture. I have improved its performance to the extreme. as I said before, it was designed to make up for the performance problems encountered in the project. it can be sai

ORM Framework Presumably everyone is familiar with, that is, object-relational mapping (English: Relation Mapping, abbreviated ORM, or O/RM, or O/R Mapping), is a program technology, Used to implement transformations between data in different types of systems in an object-oriented programming language.In effect, it actually creates a "virtual object database" that can be used in a programming language. When

See the 2016 version of the Laravel series Getting Started tutorial (a) Here is a passage: Eloquent is the Laravel ORM, the most powerful place in the Laravel system, not one of them. The original Laravel author in the development of the first version of the time spent a full one-third to get out eloquent. Of course, "to practice this work, must first self-palace", eloquent is also the slowest place in Laravel, so far cannot solve. (Routing, au

Preface Prior to contact programming, although also contact soon (cover face) at the beginning of the original SQL is not skilled, do the project when the direct use, resulting in the beginning of the whole of the SQL knowledge a bit biased, it is hairenbujian, but after learning to slowly start to break out of this pit, a lot of things, such as frame what, If we can only use, the principle does not understand and do not want to understand, then the programming of this will be more narrow, back

Also see ORM run points, to tell the truth, this ORM run points meaningful? But also the crowd, like to see the lively people are really a lot of ah. Often see a lot of people, in blowing an ORM performance how, how good, and then supplemented by a few unit test run points to support, and our heavenly mobile phones boast good performance, the price is cheap what

The origin of ORM: currently popular programming languages, such as Java, C #, and so on, they are object-oriented programming language, and the current mainstream database products, such as ORACLE,DB2, is still a relational database. The development and coordination of programming languages and underlying databases has spawned an ORM framework. ORM Framework ca

programming, it is the creation of an interface that defines all the transactional methods that will be used in this application. In this application, the interface is used when it is necessary to interact with the data source, and a separate class is written to implement the interface that logically corresponds to this particular data store.As the name implies is dealing with the database, sandwiched between business logic and database resources, is the specific implementation of the DAL.Simpl

Objective:After the framework open source, learning to use more and more people, so I also more actively in the code to respond.After the framework is complete: the database reads and writes the detach function and the distributed cache function:After three days of sleepless nights, I finally finished the third heavyweight function of the framework: automated distributed caching.Source code has been submitted, the source address see: Finally wait for you: Cyq.data V5 series (

Using the ORM in the Python Django framework to establish the query API, djangoorm Summary In this article, I will directly discuss the use of Django's low-level ORM query methods from the perspective of anti-pattern. As an alternative, we need to establish query APIs related to specific fields in the model layer that contains business logic. These APIs are not very easy to do in Django, however, I will tel

The previous article discussed how to implement the data access layer using SQL statements and stored procedures. In this article, we will discuss how to implement the data access layer using Orm. Object/Relation Mapping (ORM) is generated with the development of object-oriented software development methods. Object-Oriented development is the mainstream development method in today's enterprise-level applica

definition through Metaclass. ORM is a typical example. #ORM全称 "Object Relational Mapping", which is the objects-relational mapping, is to map a row of a relational database to an object, # that is, a class that corresponds to a table, which makes it easier to write code without having to manipulate SQL statements directly. #要编写一个ORM框架, all classes can only b

The data on the website exists in the database. Generally with MySQL, also useful sqlite,postgre. Operating the database to get the SQL language, this is a bit cumbersome, often need to look up manuals. In addition, each database in the implementation of the SQL language, often feed, add some of their own unique things. Moreover, the SQL language is not object-oriented/object-based, and many things that are more abstract are not available.So, the ORM
