DB synchronization

Imagine, what you have many texts. You can edit them and even not only you. Also you can add them into one big DB an even not only you. So, when one text imported in general DB then second time you may need to resolve conflicts. You also has general DB on other computer with other texts and you need to synchronize these two general DB. So, the question is "Is there SDK what can help me with this two synchronizations?". Thanks.

Ups.. Objective-C.

I'm having a hard time understanding your post. Let me know if I misunderstood:

1) You have Database A that has text data being modified by multiple users.
2) You have Database B that has text data being modified by multiple users.
3) You want to synchronize databases A and B
4) You use Obj-C

Is that correct?

Note quite. And it may be not texts, sequence of events, geo coors, etc... something other type of data.

All data stored together in one big DB. Also every single text, sequence, ... may be imported from file. This text may already be in big store, if yes, so i need to synchronize new data item with previous. For example, if it is a sequence, so insertion confirm by default but updation and deletion need for user approval. Surely every data item has unique identifier.

Also i need synchronize two big DB to have all data items in every DB.

Best thing to do is use a RDBMS such as PostgreSQL. That will handle simultaneous access and then you can just replication to deal with sync problems. I believe Slony-I is the PostgreSQL option on that front.
