In the following example, Data Entry Forms are reconciled, entered, linked and approved at each regional site for the ongoing operations in that region. Using the Export Data Entry Forms functionality in the Advanced Search, the regional sites export data on a regular basis (for example, monthly) and send it to the Central Mine Action Authority. The Central Mine Action Authority then imports the maXML files from each site and resolves any issues with the imports as well as performs final quality control. When the import is complete, the Central Mine Action Authority compiles a set of national statistics and then distributes a complete dataset (in the form of a database backup) to each of the regional sites. The regional sites then shares the backup to the operators.
{{Outdated| }} XXXThe The regional sites restore the dataset and then import any data entered since the last export was sent to the Central Mine Action Authority. When the backup is restored, regular data entry and exchange can continue, based on a common dataset.
This straightforward approach to decentralised data exchange ensures that all sites regularly receive a complete and authoritative dataset. Other variations on this pattern are possible with varying degrees of increased complexity to meet specific data exchange needs. Regardless of the information exchange pattern selected, there are several key aspects of maintaining decentralised data exchange within {{IMSMANG}} that must be considered. These aspects are discussed in the following sections.
==Ensuring Correct Roles and Permissions are Assigned==__NOEDITSECTION__
Establishing correct roles and permissions is a key factor in managing and maintaining data exchange within {{IMSMANG}}. Using the permissions structure, the information manager can carefully control access to key functions that affect data exchange including Data Entry Form template creation, CDF creation, Data Entry Form approvals and auxiliary data creation. When permissions are correctly established and roles and user accounts created, information managers can freely distribute the {{IMSMANG}} dataset to regional partners knowing that key data controls are in place.
Using the example of the Central Mine Action Authority and regional sites, the following principles for user account creation and permissions should be considered:
* '''Central Mine Action Authority''': Ensure Central Mine Action Authority has exclusive control over user accounts and roles, Data Entry Form templates, the Data Inventory Manager and auxiliary data.
* '''Regional Sites''': Ensure that regional sites have data entry, approval and import/export permissions. Remove permissions for user accounts and roles and auxiliary data.
By establishing a set of limited permissions for the regional sites, information managers can prevent the accidental or intentional creation of new data elements not available at the Central Mine Action Authority that could affect the ability of the Central Mine Action Authority to import Data Entry Forms and cause the dataset to become fractured.
