Data Lock solution

InProgramIn encoding, we often encounter a problem where we need to lock a row of data and can only modify it by ourselves. We do not allow changes when processing an order, ),

There are many solutions

1. You can use process control:

2. Permission control can be used (only the data is allocated to the specified person): difficult permission allocation is chaotic, and the process can be merged here.

3. Automatic Control (Lock objects with a program or lock database records): the difficulty lies in when to release the control.

4. You can also refer to version control tools (such as VSS and SVN)

Here, there are many disadvantages in the four three models, and it is difficult to implement the automatic release control solution. Currently, it is recommended that solution 4 be implemented (the Merge function is not enough, it is too complicated, and the exclusive mode is migrated out) the simple explanation is that the system does not automatically add an export function, and the locker is unlocked under the personal lock record. The administrator can unlock the lock like VSS.
