FlowX.AI
FlowX.AI
For years, enterprises have been promised useful tools for application modernization, digital product development, and no-code/ low-code. But these promises have not been kept. Instead, enterprises got a thousand disjointed point solutions, that don't scale, and ended up captive to proprietary languages and fixed vendor solutions. Enterprise customers face an urgent need to modernize, with ~80% of IT budgets locked up in maintaining old legacy systems. They demand fast integrations with simplified, lower-cost implementations. There is tremendous competition. Securing market share is hard enough. Growing is significantly harder. Enterprises need to build complex omnichannel digital products that provide an excellent user experience. People are sick and tired to be locked into proprietary programming languages, with compounding vendor fees and add-ons. Large enterprises need the freedom to build and extend easily their digital platforms. -

IBM Wazi for Dev Spaces provides a modern experience for mainframe software developers working with z/OS applications in the cloud. Powered by the open source projects Zowe™ and Red Hat OpenShift Dev Spaces, IBM Wazi for Dev Spaces offers an easy, streamlined onboarding process to provide mainframe developers with the tools they need. Using container technology, IBM Wazi for Dev Spaces brings the necessary tools to the task at hand. It provides a single-click developer workspace and eliminates local environment configuration. IBM Wazi for Dev Spaces devfile registry is a web service that provides a list of Wazi for Dev Spaces stacks to create ready-to-use workspaces. The list of stacks is used in the quick add, CodeReady Dashboard. A devfile stack contains the definitions for an application developer workspace based on devfile specifications.

TestMatch
Astadia
TestMatch is a transaction content comparison tool that provides automated testing of mainframe OLTP (terminal-based Online Transaction Processing applications). It can be used to facilitate the migration of such legacy applications to open systems, or it can provide an automated regression test suite for an application. All user interactions can be recorded centrally on an IBM or Siemens mainframe using standard tools (no client-side or server-side installation of Astadia's tools). Since recording is performed at the network level, it works regardless of the development technology. TestMatch visualizes test scenarios and sessions: this includes the terminal contents as well as all attributes that are typical for terminal-based applications, protected/editable, MDT bit, reverse-video, and colors. TestMatch can replay the recorded scenarios, either against the migrated application (as a migration testing tool) or against the original application (as a regression testing tool). -

BMC Compuware Topaz is a comprehensive suite of modern mainframe development and testing tools designed for greater developer productivity, no matter how old or complex the program. Get modern mainframe development and testing with better visibility and knowledge. A Compuware-commissioned Forrester Consulting study found that 64 percent of mainframe-powered organizations are running over half their mission-critical workloads on the mainframe. Meanwhile, they are only replacing one-third of retiring experts. Given this new reality, it is critical companies adopt a force multiplier that lets their development teams accomplish more with less. The Topaz suite can help mainframe developers at all experience levels quickly understand, update, test, maintain and troubleshoot even the oldest, most complex or most poorly documented systems.

SnowConvert
Mobilize.Net
From the makers of the heavily used SnowConvert for Teradata and SnowConvert for Oracle comes Mobilize.Net SnowConvert for SQL Server. SnowConvert automates the code conversion process to get you up and running on Snowflake faster. This is not "find-and-replace" conversion, but a complete semantic recreation of functionally equivalent code in Snowflake. While SnowConvert for SQL Server automates the code migration, it's also a code understanding tool. SnowConvert builds an abstract syntax tree and a complete symbol table that create a semantic model of the source when you point it at any source codebase to perform the conversion. Out of those two artifacts, we can provide you a level of detail on the code that is present that you can only get with Mobilize.Net. You'll get a complete list of every object (tables, views, procedures, functions, and other elements) found in your code.
