Abstract

In the first part of our An Application Architect's Guide series, Data Connectivity for Critical Business Systems, we described the integral role that the database connectivity layer provides in critical business applications. These critical business systems have zero tolerance for delays or errors relating to accessing, processing, and storing data. Inefficient or unreliable data connectivity can lead to poor performance, availability, and scalability, and to data integrity issues. Application issues can directly impact the revenue, cost, and risk structures of the organization.

This paper outlines the data connectivity options available to software architects. It should be used as a guide to ensure that the database connectivity options selected at design time meet the requirements of production systems.

Key Highlights

• Your database connectivity choice plays a critical role in the overall success of an application, greatly affecting production performance, reliability, and scalability.
• Choosing the right data connectivity option at design time can dramatically reduce the time spent developing, testing, and deploying critical applications. Architects are best served by making a pro-active, conscious decision regarding their data connectivity solution.
• The default connectivity options provided by database vendors frequently fall short in terms of quality, reliability, and performance requirements of critical systems. This results in additional application risk while driving up the overall development and maintenance costs of the application.
• Open source projects are appealing because they have no upfront cost. However, a variety of technical, legal, and support issues make open source alternatives impractical for critical production systems.
• Independent data connectivity vendors are the preferred choice for architects designing systems with significant requirements for performance, reliability, and interoperability.
