Information systems EAI, ERP, SCM (information islands are compatible with systems)

Let me add something to your supplement:

If ERP is a new system relative to the original business system, there are two situations. One is ERP products provided by the same enterprise, such as U852 of UFIDA upgraded to U890 or U9. In this case, the general data format does not need to be greatly changed, and EAI (here, it refers to a product module of U8) is not needed. In another case, the new system is the system of other manufacturers. For example, other manufacturers used it before, but now they want to change it to U8. Data is more important, and enterprises can convert data through EAI if they are willing to spend money.

As for docking, the same manufacturer, such as UFIDA's products, shares unified database basic data through * *, and uses and links related fields and parameters to complete collaboration. The products of different manufacturers are coordinated by reading the data of other systems through related software interfaces (which need secondary development). In other words, the essence of software collaboration is data collaboration.

———————————————————————————————————

The compatibility between the old and new systems is generally due to the inconsistency of data formats between the old and new systems, so it is necessary to unify the data formats to ensure the smooth switching between the old and new systems and ensure the normal operation of the old data on the new system. Generally speaking, software vendors will provide this service, but in most cases, more complex and more data will be charged.

Information island refers not to the old and new systems, but to the cooperation island between various departments of the enterprise. For example, UFIDA software is used in finance, and other software is used in human resources. With different data formats and disconnected systems, cross-departmental business process flow and data sharing cannot be carried out. However, information exchange between departments is increasingly needed in enterprise informatization. Each department cannot share the data and information flow of business processes, and each group of data creates an information island.

EAI should be compatible with multiple systems and eliminate information islands. EAI supports all systems by exchanging or converting data in different formats, and achieves the purpose of data sharing.
