Microsoft SQL Server Integration Services (SSIS) is designed to combine the features of SQL Server with components of Enterprise Management System (EMMS) so that they can work together for enterprise solutions. Its core area of expertise is bulk/batched data delivery. As a SQL Server collection member, Integration Services is a logical solution to common organizational needs and current market trends, particularly those expressed by previously installed SQL Server users. It extends SSIS functionality, such as data extraction from external sources, data transformations, data maintenance, and data management. It also helps to convert data from one server into another.
There are several ways to use SSIS. External data sources may be data obtained from an outside source, such as a third-party application, or data obtained from an on-site database, such as a company’s own system. These external sources may contain transformations, including automatic updates, or specific requests, such as viewing certain data sources. There is also the possibility of data integration, in which different sets of data sources may be integrated into SSIS. Integration Services is useful for developing, deploying, and maintaining customer databases and other information sources.
The advantage of integrating SSIS with other vendors’ products is that it allows information to be made available within the organization and outside the organization. In other words, vendors can sell to internal users as well as external customers. Integration Services is usually sold as part of Microsoft SQL Server solutions. However, some companies may develop their own SSIS interfaces and build the entire communication layer independently.
There are a few disadvantages of using SSI, however. SSI is quite slow when compared to VBA and another object-oriented programming (OOP) methods. SSI also has some disadvantages in data quality, and the SSI interface can be difficult to use if one does not know how to code in the programming language. SSI is also limited in the number of programs and applications that can be integrated into one installation of SSI.
SSI is not only less flexible than VBA but can also be slower when compared to the traditional VBA script programs, as well. SSI can use a program or server with an SSI interface. Still, not all programs and servers that support SSI will provide an interactive command line for integration with a Microsoft SQL Server Integration Services database. In some cases, an interactive command line is necessary for SSI to use the DTS file necessary to process the data from an in-house database. SSI cannot connect to SSO independently but can use an in-house or external SSI file as a starting point for a connect and bind scenario.
For SSI to work effectively in a team-based development environment, the developer must understand and be familiar with the program. SSI has been designed with several different developer topologies and languages to write code and have it run in a timely manner while keeping track of files that might not be included with the program. A team-based development environment should be defined as a group effort where regular communication between team members and corporate databases can help this process along. SSI was designed to provide developers with the flexibility and control they need to maintain these relationships.
SSI can provide several advantages over VBA, including support for data structures in various programming languages and formats. This type of integration can save time for a business and is very cost-effective. SSI also provides several different programming interfaces and is flexible enough to use in any environment. If your company needs to use SSI, you must take the time to learn how to integrate it with your company’s database to ensure that the data structures used are compatible and effective for your application.
