Thoughts on application integration status of a large enterprise

A large enterprise builds multiple IT systems around the supply chain, and data exchange and collaborative business processing are required between systems. This requires system integration. Currently, the enterprise's system integration status is: data and processing logic separation, data is transmitted independently in the form of files, the processing logic depends on a lightweight cross-platform Batch Job Scheduling management software for integration. A major prerequisite for this integration mode is that the system processes data in an offline manner, there is little need for real-time data analysis (the reason is determined by the business characteristics of the enterprise) I. Data integration between systems uses the data of a major system as the standard data, all files are passed to other systems. Some data types are send full data, and some send incremental data, depending on the business attributes and data volume of the data. Advantages and disadvantages of transferring data in file mode: lightweight, simple, common, easy to save, archive management disadvantages: Not Suitable for data transmission with high real-time requirements, data files must be generated and parsed in the agreed format, which increases the workload. 2. process logic integration between systems since data is transmitted independently and processed offline, in this way, a request initiated by a user from a system needs to be transmitted between multiple systems, data is collected and processed, and then the user waits for the returned results online, on the one hand, the current system uses the data that was last synchronized, and the current system does not directly retrieve the latest data from the original system. On the other hand, if the data processed by the current system is to be transmitted to other systems, it is also transferred at a periodic point and will not be passed out in real time. Therefore, the integration of processing logic is much simpler, so it can only be called regularly through job scheduling tools. In the final analysis, most of the business processes of the entire enterprise can be processed offline.
