Advanced SQL Schema Customization & Reporting
Presented By: John Dyke
As day to day business needs become more complex so does the need for specifically tailored and timely access to your SQL data. MSGL provides a wide array of data access tools and methods but sometimes you might require customized access to integrate into your existing reporting and management tools or wish to develop new ones. This session will focus in on the SQL schema (structure and naming conventions) along with the do’s and don’ts of how you can accomplish your customized reporting needs by using specific examples.
Highlights of this session include:• Schema (structure and naming conventions)• Custom views• Data replication• Performance tuning
Feel free to ask specific questions to focus in on areas that concern your business most.

• Creating custom web services• Integrating with other applications• Implementing custom applications
• Keeping everything synchronized• Data replication
• Performance tuning your Élan database customizations

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

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

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]

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

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

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

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

Performance tuning your Élan database customizations
• Activity Monitor – New SQL Server 2008 Dashboard
• Overview – Provides a dashboard of intuitive graphs and charts that illustrate SQL’s Processor Time, Waiting Task, Database I/O and Batch Requests/Sec

• Data File I/O – I/O activity for relational database files. Shows info for both system and user databases.

Performance tuning your Élan database customizations
• Recent Expensive Queries – gives you the opportunity to capture queries that are performing the worst and is negatively impacting the server. Gives you around 10 -15 worst queries.

Performance tuning your Élan database customizations
• Use the SQL Server Tuning Advisor – This will give you advice on adding indexes, views etc… Use Profiler to get queries to test your performance.

• Once the Analysis is complete there will be recommendations for you.

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
