- Packages – A package is a collection of tasks framed together with precedence constraints to manage and execute tasks in an order. It is compiled in a XML structured file with .dtsx extension.
- Control Flow – It acts as the brain of a package.It consists of one or more tasks and containers that executes when package runs. Control flow orchestrates the order of execution for all its components.
- Tasks – A task can best be explained as an individual unit of work.
- Precedence Constraints – These are the package components that connect the tasks together and manage the order in which the tasks will execute.
- Host Containers – The Control flow tab (window) is itself host Container.
- Containers – Core units in the SSIS architecture for grouping tasks together logically into units of work are known as Containers.
- Connection Managers – Connection managers are used to centralize connection strings to data sources and to abstract them from the SSIS packages. Multiple tasks can share the same Connection manager.
- Data Flow – The core strength of SSIS is its capability to extract data into the server’s memory (Extraction), transform it(Transformation) and write it out to an alternative destination(Loading).
- Sources – A source is a component that you add to the Data Flow design surface to specify the location of the source data.
- Transformations – Transformations are key components within the Data Flow that allow changes to the data within the data pipeline.
- Destinations – Inside the Data Flow, destinations consume the data after the data pipe leaves the last transformation components.
- Variables – Variables can be set to evaluate to an expression at run time.
- Parameters – Parameters behave much like variables but with a few main exceptions.
- Event Handlers – The event handlers that run in response to the run-time events that packages, tasks, and containers raise.
- Log Providers – Logging of package run-time information such as the start time and the stop time of the package and its tasks and containers.
- Package Configurations – After development your package and before deploying the package in production environment from UAT you need to perform certain package configurations as per production Server.
