Without having read extensively on the two and their differences, one thing that jumps out immediately is the fact that CDC is only available on SQL Server Enterprise. 在没有广泛阅读两者及其区别的情况下，立即跳出的一件事是CDC仅在SQL Server Enterprise上可用。 It also looks like CDC would use significant storage space and incurs a performance hit but SqlDependency is only recommended for a small number of dependent clients. 看起来CDC会占用大量存储空间并会导致性能下降，但是仅建议将SqlDependency用于少量的依赖客户端。
