Database has secured high-volume transactions and supports fast, compliant workflow processing
Sterling B2B Integrator is a highly transactional-oriented application, which can be described as an OLTP application. Any data that flows through the application is stored in the database for each step that it performs. IBM Db2 Database helps the application work much faster from an OLTP perspective. IBM Db2 Database is SSL enabled, which means that from the security point of view, any access to the database is through SSL. Additionally, all compliance-related aspects have been taken care of from the database point of view, including database encryption and security-related features. It is highly scalable, and its performance related to database pruning is very good. It can be scaled vertically or horizontally so that data insertions and data access are much faster and more secure compared to how Oracle or other databases work.
