Introduction to the Multi-User Version
The single-user version of Transana is designed for projects where all of the analysis is conducted on a single computer. It is self-contained — the Transana application, the media data, and the resulting analysis (in the Transana database) are all located on the same computer. Only one person at a time can work on it.
In contrast, the multi-user version of Transana shares the analytic data. It allows users on different computers (and potentially in different physical locations) to make changes to the same analytic data files (in the Transana database) at the same time. Transana Multiuser is ideally suited for projects where several researchers are working collaboratively on the same data.
Multiple researchers can connect to the same data at the same time, and Transana Multiuser keeps everything synchronized. If one user adds new data, that data will appear automatically in all other researchers’ copies of Transana. When someone codes some data, that coding is available to everyone on the team instantly. Even distant collaborators always have the latest analytic data.
The Transana Multiuser Model
The Transana Multiuser system is made up of several parts.
Each research team member has a copy of the Transana Multiuser Application, configured to access the correct database.
All research team members share a single Transana database, stored on a shared server. (More on this below.) This database contains:
- all Libraries, Documents, Episodes, Transcripts, Collections, Quotes, Clips, Keywords, Codes, Notes, etc.
- All TEXT data, including the contents of Documents and Transcripts. (Text data is small and changes frequently.)
All Image and Media data (still images, audio files, video files) are shared through networking at each research location. (Image and media data is large and doesn’t change.)
The Transana Message Server (shown in green) keeps all copies of Transana Multiuser connected to the same data synchronized.
This mixed model for data sharing allows for the best of both worlds. Data that is frequently changed during analysis is centralized to optimize data sharing. Data that doesn’t change during analysis is distributed, allowing higher quality media files with faster access while avoiding all the problems that come with video streaming.
Transana Multiuser requires internet access and a server to accomplish data sharing. There are two options:
You can set up your own server with appropriate technical support and expertise.
You can subscribe to the Transana Cloud Service and use our server.
