lock & read or just read?

Hi all,

My assignment has the following comment on the lock(int) method: Locks a record so that it can only be updated or deleted by this client.. So what I am thinking is to only use the physical locking (ie locking on the database file) when reading a record. An additional record locking (along with physical locking) will be only used when updating/deleting a record.

DBClient class



Data class:


Do you think it is an appropriate approach to the read method?

Hi Alex,

I think that is suitable for the read method.
