Abstract
Multiuser real-time editors tool allow a group of distributed human users to edit a shared graphical document at the same time over a computer network.
In this project a normal operation transformation framework is developed to efficiently share the text and graphical data to the different users or a particular user connected in the network.
Operational transformation (OT) is a well-established method for optimistic consistency control
This project analyzes the root of correctness problems in OT and establishes a novel operational transformation framework and proving their correctness.
Operational Transformation(OT) has been well accepted in group editors for achieving high local responsiveness and unconstrained collaboration.
Remote operations are transformed before they are executed such that inconsistencies are repaired.
Existing System
In existing system, the group editors can work only 2 members by request-response process
So it has a problem of consistency control and take more time to process group editors
There is no sharing of graphical data
There is no system to have a shared network that facilitates with editing graphical data
Proposed System.
The proposed system consists of novel OT Frame work to address the weakness of previous system based on a concept called “operation effects relations”.
System consists of two criteria, causality preservation and operational effects relation preservation for verifying the correctness of OT algorithms.
Sufficient conditions for transformation functions are identified and second special operational path is chosen to satisfy the condition
OT principles
An OT framework considers n sites, each site owning a copy of shared data.
When a site performs an update, it generates a corresponding operation. Every operation is processed in four steps:
executed on one site,
broadcasted to other sites,
received by other sites,
integrated and executed on other sites.
How will the system work
Given Input
Sender can be able to give the text message in the text box
Sender can choose the individual receiver from the list box
Sender can draw the object in drawing pad
Sender can choose the type of drawing object
Sender can choose the color of drawing object
Sender can send message
System automatically give color object
System automatically give size of the objects
Conclusion
Research has been conducted in organizations and it was found that group or team works tend to increase the productivity and creativity.Multi-user real-time editors tool with OTF, allows group of human users to edit the same graphical document at the same time.Enhancement can be made to make it possible to edit other kinds of documents like architectural design in the field of civil engineering.
