Until the protocol is not developed, RescoManager will have to be installed in a server, and all the users will need to access, enter and modify data on-line. This requires them to have Internet connectivity at all times.
Once the data synchronisation protocol has been developed, users can work off-line as well as on-line, with the data being synchronised as soon as two computers with the software installed enter into range.
1. Types of synchronisation
The protocol should allow for background synchronisation between nodes. Options to be used should be based on:
The project to be developed must be capable of synchronising an SQL database between 2 or more computers without intervention from the user.
2. ORM data
The nodes will function offline and synchronise with their main node and their secondary nodes when they go online. There will be no connection between nodes most of the time.
3. Methods of synchronisation
5. Access to parent nodes
Each node will be linked to its parent node through a URL that will contain the access and content of the data to be synchronised.
6. Data integrity
The data replaced must remain in tables to trace all updates carried out.
7. Conflict resolution
An optimistic conflict resolution system must be used, as in the majority of SGBD.
8. Data filter to be updated
The content of the data to be updated will be defined by SQL sentences in two cases:
9. Error management and register
An thorough register must be made of the actions performed in the database and in the communication process.
10. Resource monitoring
Production will be carried out in diverse environments and platforms, some of them very limited (OLPC). Therefore, the process must function while monitoring the free space on the disc and minimise the use of RAM memory.
Justification: make possible for RescoManager to run off-line

Jordi is expected to design and program the protocol. Nevertheless, the protocol could be developed as a PH or thesis by a student on its final year in information technology, or by anyone with the skills and willingness to contribute.
