When it comes to extracting, transforming, and loading data, there are two major ETL solutions: DTS and SSIS. While they share some similarities, there are also some key differences between the two. In this blog post, we’ll take a look at those differences and help you decide which one is best for your needs.
What is DTS?
DTS Data Transformation Service is a cloud-based data integration service that helps you move data between on-premises and cloud data stores. DTS supports heterogeneous data sources, such as Oracle, SQL Server, MySQL, PostgreSQL, and MongoDB. DTS also includes a Data Integration Job feature that lets you schedule and automates data transfer operations. DTS is available as a pay-as-you-go service or as part of an Azure subscription. DTS includes a web-based portal and a REST API for managing data transformation jobs. DTS is available in all Azure public regions. DTS supports Microsoft Active Directory for authenticating users and authorizing access to DTS resources. DTS uses Azure Storage for storing data and metadata. DTS jobs are executed on Azure Virtual Machines. DTS charges for the compute resources used to run data transformation jobs. There is no charge for data storage or network bandwidth usage. DTS offers a free trial and a pay-as-you-go pricing model.
What is SSIS?
SSIS or SQL Server Integration Services is a platform for data integration and workflow applications. It features a fast and flexible drag-and-drop UI, a powerful Data Flow engine, and a rich set of SSIS connectors and tasks. SSIS also includes a rich set of transformation components that can be used to cleanse, de-duplicate, and aggregate data. In addition, SSIS provides robust connectivity to a wide range of data sources, including relational databases, flat files, XML documents, and Web services. SSIS is easy to use and provides all the features you need to build sophisticated data integration solutions. With SSIS, you can move data quickly and easily from one data source to another, transform data as needed, and load data into your target systems with ease. SSIS is the perfect tool for building ETL (Extract-Transform-Load) solutions for your data warehousing needs.
Difference between DTS and SSIS
DTS is a legacy data transformation service that was introduced in SQL Server 2000. SSIS is a newer data transformation service that was introduced in SQL Server 2005. DTS does not have a graphical designer, and it is not as easy to use as SSIS. DTS uses ActiveX Scripts for transformation logic, while SSIS uses Visual C# or Visual Basic .NET for transformation logic. DTS is less reliable and does not scale as well as SSIS. DTS is being replaced by SSIS in new development projects.
While both services have their benefits, DTS is the better choice for most businesses. It’s more affordable and easier to use, making it a great option for small to mid-sized businesses that need to move data between systems. If you’re looking for a powerful and versatile data migration tool, SSIS is the better choice, but it will come at a higher price tag.
