Methods and systems for performing three-way merge of models

A method for implementing data model management at a data model repository comprising:

• storing a data model at the data model repository;
• sending the data model stored at the data model repository to a first client and a second client;
• receiving and storing, at the data model repository, a first delta data generated from changes made by the first client to the data model;
• receiving, at the data model repository, a request from the second client for the first delta data;
• sending the first delta data generated by the first client from the data model repository to the second client;
• and
• receiving and storing a merged delta data incorporating the first delta data and a second delta data generated by the second client from the second client.

A system for implementing data model management, the system comprising:

• a first client terminal having a first client application stored thereon that comprises computer-readable instructions instructing the first client terminal to execute:
• receiving the data model from a repository;
• generating a first delta data from changes made by the first client application to the data model;
• detecting whether a second delta data, which is generated from a second client terminal by making changes to the data model using a second client application implemented on the second client terminal, is stored in the repository;
• sending the generated first delta data to the repository when the second delta data is not stored in the repository;
• when the second delta data is stored in the repository:
• requesting the second delta data generated by the second client application from the repository;
• generating a merged delta data by merging the first delta data with the second delta data;
• and
• sending the merged delta data to the repository.

A system for implementing data model management, the system comprising:

• a repository comprising a processor having computer-readable instructions stored thereon instructing the processor to execute:
• storing a data model;
• sending the data model to a first client and a second client;
• receiving and storing a first delta data generated from changes made by the first client to the data model;
• receiving a request from the second client for the first delta data;
• sending the first delta data generated by the first client to the second client;
• and
• receiving and storing a merged delta data incorporating the first delta data and a second delta data generated by the second client from the second client.
