• Business Logic Layer: Based upon business rule and workflow engine, this layer provides security and business process automation. It can also be exported as SOAP Web services.

• Persistence Layer: It is consisted of Java Persistence API (JPA) and other object-relational mapping technology to establish data sync between applications.

A systematic and simpler method to choose an ERP Application based upon common requirements which are consisted of availability, customization, modification, integration and flexibility.

Please find below the requirements:

• Availability: The application on the restart on the code updates be featured to provide more data availability on servers.

• Customization: The ERP development process be based upon enhanced capabilities for customization for processes like messaging, database vendor or workflow with either XPDL standard. With better customization features a developer is only required to make a simple change to XML specification in order to move to a different component.

Saving deployment time it makes the entire process of deployment simpler and easier.

• Application Platforms: The software platform on which an application development is architecture should be easy to be understood. Whether it be Java, XML or any other technology, the development team inhouse must be able to interpret codes according to a company’s architecture.

• Simplified Business Logic Integration: The application integration into ERP be seamless providing business logic layer available to a clients, automatically. The developer only be left with jobs like plugging in small segments of reusable business logic code in Java or a scripting language.

CONCLUSION

In order to choose a vendor or application for an ERP app development, an enterprise really need to jot down the features and qualities it is looking into an ERP software developer. The selection of the developer along with process enhancement should be based upon the ease of integration for the in-house development team.
