Some examples of previously completed data/SQL projects include: • Writing SQL scripts to perform various database functions such as changes to table structures and record inserts. • Packaging SQL queries/stored procedures into user friendly applications such as Excel, Access or bespoke .Net applications – allowing them to be run easily by end users. • A data improvement project involving identification of gaps in CRM data; documenting recommendations for improving the quality and standardising field values; implementing data updates and introducing field validation. • Develop a small MySQL database to hold IP ranges and country data.
