Design of data layer of CRUD full-stack programming architecture CodefirstAll this time, when we write applications, we start by creating databases.Finally, after the ORM supports Codefirst, we can model it first.The model to create the database, and based on Codefirst can be implemented convenientlyImplementation of database migration. There are several techniques for using Codefirst,Taking EntityFramework

Many friends asked SQL server database "generate scripts" and exported only the SQL scripts of the database, while the data in the table is still not exported. It is very simple. Take a look at the Tutorial: Note: I use SQLServer2008 here. Other versions should be similar. 1. Select the database to be exported-> task-> Generate script (or you can find the script generated in the task !) 2. In the "Generate and release scripts" window, click Nex

When interacting with a local cube, admod. NET and analysis management objects (AMO) will also load the local cube engine. Only one process can access the local cube file, because the local cube engine will exclusively lock the local cube file when establishing a connection to the local cube.A process can
