Abstract: An apparatus, system, and method are provided for enabling web-applications to access enterprise managed data. The invention includes a recoverable resource manager (RRM), a transaction converter, an interface, and a results converter. The RRM provides transactional recovery and transactional access for a plurality of applications including the web-applications. The transaction converter, interface, and results converter cooperate such that relational data requests sent by the web-application access the non-relational data through the RRM and return relational results from non-relational results provided by the RRM. In one implementation, the present invention provides transactional access to web-applications for VSAM data accessible exclusively through a z/OS operating system.
