When an application performs a CRUD on a database, through the Entity Framework, it actually operates on DbContext, DbContext is the entry for EF, and DbContext gets the corresponding message (CRUD), The object o is mapped to the relationship R in the database using the mapping in the ORM.The following is a simple implementation of the use of the Entity Framework

Structure : ( Note: In the delivery of the program, many friends because only the text of a simple description of the function, signed the contract, in the implementation of the development, because no prototype in the contract to confirm, most will be repeated rework, repeated requests for various modifications, the project dragged and dragged end, has not received the tail money and cumbersome, so the best in the plan, in addition to the text descr

configure properties):Where c3p0 is used, its configuration file is:3. Briefly describe the connection of the database in SSHThe database connection path and password are listed in the following format, for example:According to the above information, in the code can be written as:In the SSH framework, the configuration file for database information needs to be added in Applicationcontext.xml:(Thus, an external property file is introduced)Above, is a

ObjectiveOn the last day of the 30-day challenge, I decided to learn the Play Framework. I wanted to write Sacla, but after a few hours of research, I found it impossible to just evaluate Scala within a day and spend some time next month to learn and share experiences. In this paper, we first look at the Play Framework Foundation, and then develop a program.What is a play frame?Play is an open-source, moder

I recently learned some knowledge about asp.net mvc, so I want to use a small project to train my hands and improve my code and thinking skills. before that, it was very easy to do east and west. We directly used the software to generate code and generate a simple three-tier architecture as the overall framework of the project. The database access layer uses ado.net. it is quite troublesome to do this. If y

Previously wrote an article Flask development environment build, continue today, carry on a small project-blog system of actual combat. Blog system is very simple, only one page, and then small perfectly formed. The goal here is not to do projects for the project, this article is intended to convey the following several points of knowledge through this exercise: 1. Understand the directory structure of the Flask project from a global view 2. Operatio
