How it works...
From SQL Server 2008 R2 onwards, the setup program is used to install any or all of its
components. Through this setup, you can install Integration Services with or without other
SQL Server components on a single server. The connectivity components (which are installed
by the setup) are important for communication between clients and servers that includes the
server network libraries.
The authoring and management tool such as BIDS and SSMS are essential to design, develop,
and manage the packages for ETL purposes. The service installation and service account
starts and runs as a Windows service, where each instance of core database engine services
and Integration Services is supported by its own service and each instance can use different
settings for collation and server options. Integration Services isn't just one application, but a
collection of components, utilities, engines, and wizards.
Managing the ETL process efficiently
ETL process efficiency requires a high volume of ETL throughput, where best practices for
standard relational databases and high performance techniques for packages are taken
into consideration. Similarly, the high volume ETL throughput and management require
specific considerations and implementation techniques in a data warehousing environment.
The data store that contains trends, patterns, and a history of business is essential to make
decisions. Such BI services use facts to record transactions and dimensions that contain
information about customer transactions, such as customer name, time, product sales, and
sales promotions.
Integration Services from SQL Server 2008 R2 provides a number of specific benefits
for meeting the requirements of high-volume ETL processes. High volume ETL is a data
warehouse update process that needs the infrastructure support from the technology to attain
the throughput. ETL designer from IS design toolbox helps to design the packages as a high
throughput ETL system in managing high performance data transfers. Batch windows for ETL
data processing are generally time-constrained, particularly when managing large volumes
of data. To optimize the data transfer, the destination adapter option in Integration Services
that enables the setting of Fast Load properties on the transfer are used. In order to match
up the rows written against a count, it is organized as a part of ETL transfer logic; this requires
a syntactical submission where each load should be associated with metadata describing the
transfer status, throughput metrics, and downstream reconciliation purpose.
