Large commercial banks are the main market for bank IT service outsourcing, which is the foundation for the company's continued growth. It has the advantages of multi-platform technology covering large, medium, small and microcomputers. Bank IT systems can be divided into three levels: basic hardware, operating systems, and application software. The company's business is application software development. The development and operation of application software requires an operating platform composed of hardware and operating systems. According to the size of processing capacity and level of complexity, operating platforms can be divided into mainframe development platforms, medium-sized computer development platforms, small computer development platforms, and microcomputer development platforms. Currently, business systems based on mainframe platforms are generally concentrated in large state-owned commercial banks and some strong joint stock banks. Other small and medium-sized commercial banks mainly use small and medium-sized commercial banks. Judging from technical barriers, mainframe platforms are developed based on the ZOS/MVS/ESA environment, and CICS, COBOL, and JCL are usually developed using CICS, COBOL, and JCL. These technologies are closed, have a long talent training cycle, and require a mainframe platform as a training environment, so the entry threshold for system development business based on mainframe platforms is high. The company currently has a mainframe platform development team of nearly 400 people. Rich industry experience, full process service advantages.
