Comparing Scripting Solutions and Custom Objects
An Integration Services Script task or Script component can implement much of the same functionality that is possible in a custom managed task or data flow component. Here are some considerations to help you choose the appropriate type of task for your needs:
If the configuration or functionality is specific to an individual package, you should use the Script task or the Script component instead of a developing a custom object.
If the functionality is generic, and might be used in the future for other packages and by other developers, you should create a custom object instead of using a scripting solution. You can use a custom object in any package, whereas a script can be used only in the package for which it was created.
If the code will be reused within the same package, you should consider creating a custom object. Copying code from one Script task or component to another leads to reduced maintainability by making it more difficult to maintain and update multiple copies of the code.
If the implementation will change over time, consider using a custom object. Custom objects can be developed and deployed separately from the parent package, whereas an update made to a scripting solution requires the redeployment of the whole package.
