SQL Server Developer

A basic requirements in most SQL Server based applications is implementing a database operation (DDL or DML) in a single unit of work. The DDL requirement is more from a DBA’s perspective rather than the application, since any application would perform only INSERTs, UPDATEs and DELETEs on the existing data, and a DBA would be [...]

Code review or monitoring inevitably becomes a part of our project’s life cycle. It’s a process which analyzes your code, helps to mitigate issues and reduce the percentage of bugs in testing by performing code cleaning. We can do the code review either manually or, preferably, automatically. In a big project reviewing code manually is [...]
