- | ====== Synchronization Module ====== | ||
- | |||
- | ===== Introduction ===== | ||
- | The synchronization module is one of the most important and highly required module in the sahana disaster management system in order to function the entire disaster management process effectively.This module simply does is, allows user to transport the huge amount of data in a particular sahana installation to another different sahana installation.This facility is really important because sometimes the communication infrastructure is also destroyed in disasters and the people or the relief workers are not able to communicate via a electronic telecommunication medium. | ||
- | |||
- | So in such situation, | ||
- | |||
- | This module helps not only when the communication is limited but if the relief workers want to integrate two different sahana installations ,the synchronization module again comes in to play.Because in such scenario, the databases of two installations should have consistency and user can work as they are using a one database. | ||
- | |||
- | ===== Getting started with synchronization module ===== | ||
- | |||
- | Click on the **synchronization** link in the main menu and then synchronization menu will appear on top of the main menu. | ||

- | ===== Synchronization Menu ===== | ||
- | |||
- | **__Home__** | ||
- | |||
- | |||
- | This link directs the user to the Synchronization module main window. | ||
- | |||
- | **__Export Data__** | ||
- | |||
- | Using this link the user can get a copy of the sahana database or a part of the sahana database.in **Export Data** window, | ||
- | |||
- | **NOTE :** Before click on the export button, make sure to navigate through all 3 tabs otherwise the default setting will be applied to your data copy and it may not be suitable for the expected purpose of the data copy | ||
- | |||
- | |||
- | **Select Data** The user can select the data required from the sahana database.Sahana database has been divided into several categories and user can select those a sub set of those categories or all categories.**Select All** button can be used to select all categories and using **clear** button, the user can clear all selected categories. | ||

- | **File Type** The type of the file,user want to get the data copy.First decide the transfer media of the and the usage of the data copy and select the appropriate type. | ||
- | |||
- | {{ doc: | ||
- | |||
- | |||
- | **Compression Type** This important because sometimes the copy of the database may be huge and transfer will be difficult or may cost a lot of time.Therefore apply a compression type and it will save much time. | ||

- | |||
- | |||
- | **__Import Data__** | ||
- | |||
- | This is simple because only thing user has to do is browse and select the file of data copy(obtained as described early from another sahana installation) and click ok.Then click on the **next** button and in the next window click on the **import** button.This action will look up the difference of the database and data copy (dump file) and update the data base as mentioned in the Introduction section.But if the user want to erase all the data in the database and fill the empty database using the dump file data,click on the **advance option** link in left of the **import** button | ||

- | **__History__** | ||

- | This just show you the details about imported dump files and the user can get an idea about the state of the data base and how often the data is synchronized between different sahana installations. | ||
