Create and alter tables
Design, implement, and troubleshoot security
Design the locking granularity level
Implement indexes
Implement data types
Create and modify constraints
- Develop an optimal strategy for using temporary objects, including table variables and temporary tables; define alternatives to triggers; define data version control and management; implement @Table and #table appropriately; create calculated columns; implement partitioned tables, schemas, and functions; implement column collation; implement online transaction processing (OLTP); implement columnstore and sparse columns
Design, implement, and troubleshoot security
- Implement data control language statements appropriately, troubleshoot connection issues, implement execute as statements, implement certificate-based security, create loginless users, define appropriate database roles and permissions, implement contained users, implement cross db ownership chaining, implement schema security, implement server roles
Design the locking granularity level
- Choose the right lock mechanism for a given task; handle deadlocks; design index locking properties; fix locking and blocking issues; analyze a deadlock scenario; design appropriate isolation level, including Microsoft ActiveX data objects defaults; design for locks and lock escalation; design transactions that minimize locking; reduce locking contention; identify bottlenecks in data design; design appropriate concurrency control, such as pessimistic or optimistic
Implement indexes
- Inspect physical characteristics of indexes and perform index maintenance; identify unused indexes; implement indexes; optimize indexes, including full, filter, statistics, and force
Implement data types
- Select appropriate data types, including BLOBs, GUIDs, XML, and spatial data; develop a Common Language Runtime (CLR) data type; implement appropriate use of @Table and #table; determine values based on implicit and explicit conversions
Create and modify constraints
- Create constraints on tables, define constraints, modify constraints according to performance implications, implement cascading deletes, configure constraints for bulk inserts
