SSIS Interview Question: Difference Between Connection Manager and Package Connection Manager

In SSIS (SQL Server Integration Services), a connection manager is a reusable object that defines the connection information needed to access data sources or destinations. It can be used by multiple tasks within a package or project.

On the other hand, a package connection manager is specific to an individual package. It is used to define connections that are only needed within that particular package and are not shared with other packages.

While connection managers are designed for reusability and can be shared across multiple packages, package connection managers are limited to the scope of the package they belong to.

Understanding the difference between these two types of connection managers is essential for effectively managing data connections in SSIS projects.
