What this article shares with you is about how to analyze the design and implementation of the ERP system for small and medium-sized enterprises. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Compared with the ERP system of large enterprises, the ERP system of small and medium-sized enterprises should provide some flexibility to meet the specific needs of different enterprises while integrating the concept of enterprise management. Therefore, the ERP system of small and medium-sized enterprises is not as complex as the large-scale ERP system, and the scope of business is mainly focused on the management of planning, production, purchase, sale and storage, quality, finance and other main business in the initial stage. However, from the perspective of customer flexibility, diverse personalized requirements and the vitality of software products, the ERP system of small and medium-sized enterprises is required to have good business expansibility.

1. System design objectives

As small and medium-sized enterprises have a variety of personalized and ever-changing needs, the ERP software of small and medium-sized enterprises should meet the needs of users to change conveniently on the premise of keeping the main framework unchanged. In addition, the ERP software of small and medium-sized enterprises should be an open system, which can be easily integrated with a variety of management software, allow the division of labor and cooperation among various systems, and ensure the successful implementation of ERP. To this end, the goals of our SME ERP software system framework are as follows:

The main results are as follows: (1) the system should be multi-layer in architecture, and the influence between layers should be minimized. For example, when modifying a database, you should minimize the impact on the business logic layer.

(2) taking the business module as the basic unit, the adjustment and optimization within one basic unit should have as little impact as possible on other units, and the resource invocation between units is defined by the relationship between suppliers and consumers.

(3) provide a unified functional interface standard to ensure the good scalability of the system and reduce the difficulty of docking with other products.

(4) the framework will provide a mechanism to transparently realize the exchange of visits between networks, and ensure the high efficiency and security of information transmission.

(5) establish an information center to collect, forward and manage messages and e-mails.

(6) the framework provides dynamic control of the flow of information in business modules to better support and reorganize business processes.

(7) the framework will integrate common modules such as log management, general report, rights management and general business logic classes as much as possible to minimize the amount of business system development and shorten the development cycle of business systems.

(8) the framework should provide a set of templates for creating new services for the secondary development of the system.

2. Choose the appropriate ERP system structure.

At present, almost all ERP systems adopt multi-level client / server structure. This model can manage the application more effectively, reduce the complexity of the network and ensure the integrity of the database.

When designing ERP system structure, enterprises must consider seven levels: presentation layer, application layer and data glow layer. The separation of the presentation layer, the application layer, and the database layer, whether physical or logical, has become one of the most common ways to create modular, updatable client / server applications. In this way, users can load executable applications from the database server, thus simplifying the management of the application, while each server can request its own executable module when needed. Similarly, scalable parts are accordingly simpler and can be upgraded by adding application servers.

3. Attach importance to ERP system integration.

When implementing enterprise ERP projects, the vast majority of users will generally use ERP systems from different manufacturers or encounter problems of integration with the original systems of the enterprise, so they often need to use different databases and hardware platforms. Moreover, with the implementation of these independent systems, enterprises need to integrate these decentralized ERP subsystems with each other. In view of this, users should choose the infrastructure components with the broadest market prospects, because these components are easier to integrate later. The ideal integration method is to run multiple applications on a single operating system and data model. However, while this approach can reduce the complexity of integrating related applications, it increases the implementation time. In addition, once this method is implemented, its flexibility will be relatively less. However, in the vast majority of cases, it is necessary to choose a single-vendor approach because the vast majority of application developers rely on dedicated or specific database systems.

4. Choose the right operating system

Users should consider the portability of the operating system when implementing ERP projects, because some servers can only be implemented on certain hardware platforms. For example, Microsoft-based WindowsServer servers (WS) should only consider INTEL-based hardware platforms, because they usually don't work well on non-INTEL hardware platforms.

The two most commonly used operating systems are Unix and WindowsServer. Unix still maintains its vitality and will continue to maintain its leading position in the high-end market, because it can support scalable database servers, while WindowsServer is more used in low-end servers. Therefore, for users and other advanced applications who implement ERP systems, using UNIX-based solutions will provide greater scalability, but users also need to have more technical experience and software tools resources. Recently, the application of WS is likely to have more commercial functions than Unix, because it has improved scalability and usability, and will be strongly supported by ERP software vendors. Therefore, enterprises need to deeply understand the similarities and differences between WS and Unix core technologies and work more closely with software vendors to determine whether to use WS platform or Unix platform.

The above is how to analyze the design and implementation of the ERP system for small and medium-sized enterprises. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article.
