can use the batch of one concept as a compromise between real-time and store and forward processing.

Multitiered networks

The database management systems consume a great deal of computer resources. Separating the J.D. Edwards’ applications from the database management systems allows optimum computing power for both needs. This creates a three-tiered network that consists of PC’s that connect to application servers, that connect to database servers. A fourth tier would be created if data warehousing was bought into play. Multitiered networks complicate matters, but also improve performance and scalability.

Multiple servers by vertical

OneWorld can work with mixed databases concurrently across multiple machines. Objects and data can be accessed from several mixed databases including Microsoft Access, Oracle, SQL Server, and AS/400. You can also have separate servers for different applications. For example, you can have a separate server for accounts receivable, and a separate server for manufacturing. You do not need a single, central server. This concept of multiple servers working together is central to the concept of CNC.

Data replication

Several facilities for data replication are provided by J.D. Edwards, including OneWorld application for data replication that allows for just-in-time replication, pull replication, push replication, and non-mode replication; and the table conversion utility that is a batch replication process. OneWorld can also utilize several open system tools that support the replication of data.

Departmental and application work groups

To keep data replication simple, it is often preferable to replicate data to an application server in a single group that performs the same business functions. In a departmental work group, workstations would have no replicated data. Only business objects would be replicated and maintained on the department's application server. This setup decreases the amount of data replication by minimizing the data transfer between the workstations and the application servers.
