Planning for MSGL database customization Identify your requirements What must it do? What tools will be used? Create an implementation plan Proper planning here will help minimize the impact of Élan schema changes It is HIGHLY recommended that you do this in consultation with MSGL User Group 2012 Denver

Extending the Élan Database All interaction with Élan databases MUST BE READ ONLY DO NOT modify or directly link to Élan database objects or you WILL NOT be able to cleanly update your database Views and stored procedures may be added into a separate schema Database objects WILL CHANGE Wrap Élan tables and views with custom views –Care should be taken to prevent performance issues User Group 2012 Denver

Extending the Élan Database Establish a naming convention All Élan views and stored procedures follow the convention [Module Code]V_[View Name] [Module Code]SP_[Stored Procedure Name] The following naming convention for custom views and stored procedures is [Company Name]V_[View Name] [Company Name]SP_[View Name] User Group 2012 Denver

Using new Élan database customizations: Creating Custom Web Services Use existing Élan tables and views Use custom views or stored procedures Create custom return types when returning data from Élan tables or views Tie together information from multiple sources or transform information using other applications to get the desired result User Group 2012 Denver

Using new Élan database customizations: Integrating with Other Applications Transform data from web services or SQL with BizTalk Pull data from web services into Excel for further analysis Update SharePoint with data from Élan and custom web services, SQL Reporting, BizTalk and Excel User Group 2012 Denver

Using new Élan database customizations: Implementing Custom Applications Create in-house applications Create applications that run on mobile devices for employees on the road Integrate Élan and custom web services along with other applications User Group 2012 Denver

Keeping everything synchronized Backup database and version changes Create and implement a test plan If it is automated impact of changes are known DO NOT modify or directly link to Élan database objects User Group 2012 Denver

Keeping everything synchronized: Data replication If you are hosting in the ASP environment and DO NOT have a dedicated SQL Server or have demanding reporting needs You should have an onsite SQL Server and special arrangements should be made to replicate a copy of your data to you In this case ALL custom changes must be added to a separate database User Group 2012 Denver

Performance tuning your Élan database customizations If there are recommendations, or you know you need to add performance enhancements, to add changes directly to Élan database objects Consider creating static snapshots of data which can be refreshed on demand or a scheduled basis This will trade disk-space for performance This is much cheaper than buying a more powerful SQL Server but must be weighed against how up- to-date the data must be User Group 2012 Denver
