Automatic generation of a coexistence layer using robotic process automation for application modernization

A computer implemented method for updating calls or operations in a database management system, comprising:

• mapping, by a computer processor, application programming interface (API) types associated with a legacy server and a new server, wherein the legacy server recognizes request signatures of a first API type and the new server recognizes request signatures of a second API type that is distinct from the first API type;
• receiving, by the computer processor, a request from a system of engagement resident on a client-side computing device, addressed to a system of records resident on a legacy server, wherein the request includes a call or operation;
• intercepting the request by a coexistence layer module run by the computer processor;
• determining, by the computer processor referencing the mapping, whether the intercepted request points to a system of records component that has been moved from the legacy server to a new server;
• determining whether the intercepted request uses a request signature recognized by the first API type;
• converting, by the coexistence layer module, the intercepted request to a format using the request signature of the second API type;
• sending the converted intercepted request to the new server;
• and
• performing the converted request by the new server.

A computing device configured to update calls or operations in a database management system, comprising:

• a processor operating a software transformation engine;
• and
• a memory coupled to the processor, the memory storing instructions to cause the processor to perform acts comprising:
• mapping, by the processor, application programming interface (API) types associated with a legacy server and a new server, wherein the legacy server recognizes request signatures of a first API type and the new server recognizes request signatures of a second API type that is distinct from the first API type;
• receiving, by the processor, a request from a system of engagement resident on a client-side computing device, addressed to a system of records resident on a legacy server, wherein the request includes a call or operation;
