4. What is SQL Server Integration Services Microsoft SQL Server Integration Services is a platform for building enterprise-level data integration and data transformations solutions. You use Integration Services to solve complex business problems by: processing of data into a data mart or data warehouse move data from legacy systems into new systems applications migration integrate data from multiple systems by passing data back and forth extract or import data for sending to vendors or partners cleaning and mining data managing SQL Server objects

Tasks are control flow elements that define units of work that are performed in a package control flow. An SQL Server Integration Services package is made up of one or more tasks. If the package contains more than one task, they are connected and sequenced in the control flow by precedence constraints. Containers are objects in SQL Server Integration Services that provide structure to packages and services to tasks. They support repeating control flows in packages, and they group tasks and containers into meaningful units of work. Containers can include other containers in addition to tasks. SSIS Designer is a graphical tool that you can use to create and maintain Integration Services packages. SSIS Designer is available in Business Intelligence Development Studio as part of an Integration Services project. SSIS includes additional tools, wizards, and command prompt utilities for running and managing Integration Services packages. The SSIS object model includes managed application programming interfaces (API) for creating custom components for use in packages, or custom applications that create, load, run, and manage packages. Developer can write custom applications or custom tasks or transformations by using any common language runtime (CLR) compliant language. The Data Flow task encapsulates the DF engine. DF engine provides the in-memory buffers that move data from source to destination, and calls the sources that extract data from files and databases. The DF engine also manages the transformations that modify data, and the destinations that load data or make data available to other processes. Integration Services data flow components are the sources, transformations, and destinations that Integration Services includes. You can also include custom components in a data flow. The Integration Services service lets you use SQL Server Management Studio to monitor running Integration Services packages and to manage the storage of packages. The control flow is the workflow engine that contains control flow tasks, containers, and precedence constraints, which manage when tasks and containers execute. The Integration Services runtime saves the layout of packages, runs packages, and provides support for logging, breakpoints, configuration, connections, and transactions. Data Flow Engine
6. What is SSIS Package A package is the core object within SQL Server Integration Services (SSIS) that contains the business logic to handle workflow and data processing. You use SSIS packages to extract data from sources and load it to destinations,and to handle the timing precedence of when data is processed. SSIS Package contains: Control flow elements Dataflow elements Event Handlers Data source Connections

Control flow elements prepare or copy data, interact with other processes, or implement repeating workflow. Precedence constraints sequence the control flow elements into an ordered control flow and specify the conditions for executing tasks or containers. The log providers that support logging of package run-time information such as the start time and the stop time of the package and its tasks and containers. The connection managers that connect to different types of data sources to extract and load data. The Data Sources that connect to different types of data sources to extract and load data. The event handlers that run in response to the run-time events that packages, tasks, and containers raise. The data flow components—sources, transformations, and destinations—for building data flows in a package that extract, transform, and load data. Paths sequence the data flow components into an ordered data flow. The variables that can be used in expressions to dynamically update column values and property expressions, control execution of repeating control flows, and define the conditions that precedence constraints apply.

Editor's Notes
Developing Project Data Sources and Package ConnectionsBecause the main purpose of SSIS is to move data from sources to destinations, the nextmost important step is to add the pointers to these sources and destinations. These pointersare called data sources and connections. Data sources are stored at the project level and arefound in Solution Explorer under the logical folder named Data Sources. Connections, on theother hand, are defined within packages and are found in the Connection Managers pane atthe bottom of the Control Flow or Data Flow tab. Connections can be based on project datasources or can stand alone within packages. The next sections walk you through the uses andimplementation of project data sources and package connections.
These workflow elements might involve:running a stored proceduremoving a file from an FTP server to a destination foldersend an e-mail message when an error occursPackages also contain connections to data sources and data destinations. You set up these connections to connect to different external systems such as databases, files, File Transfer Protocol (FTP) servers, Simple Mail Transfer Protocol (SMTP) servers, and so on. Connections are used for the SSIS data processing engine (called the data flow) as well as the workflow engine (called the control flow).
The objects that compose an Integration Services package include the following:The package itself The package, the unit of work that is retrieved, executed, and saved, and the most important Integration Services object.For more information, see Integration Services Packages.Control flow elements The control flow elements—tasks and containers—for building the control flow in a package.
