如何比较实体框架中具有相同表名的两个模型之间的数据？

Question

Assume you have 2 databases scripts ( Source & Destination ) with the same structure and different data.

This is the source database:

https://drive.google.com/file/d/1psVbVdJz7PbH2KXkqw1S3CkIviynIba8/view?usp=sharing

And this is the destination database:

https://drive.google.com/file/d/1EvyFqpQ_meEXOyYmoUKuZHfINEFfAN--/view?usp=sharing

1. Load data from Source Database
2. Compare the data from source database to the destination database.
3. Depending on the comparison show result in one of four groups:
   • Data already exist with no change.
   • New data ready to be moved.
   • Data to be updated.
   • Data to be deleted
4. Then I can deploy the changes to the destination Database.

Can anyone help me to solve this task?

Answer 1

Method 1:

1. Introduce inert, delete update triggers for SOURCE DB tables
   • Save changes in Log table(new table)
2. Create stored procedure to read log table and update destination DB
3. Call this new SP in schedule time via SQL jobs

Method 2:

1. Replicate source db in order to sync changes to destination.
