Database Implementation Plan for Riordan Manufacturing
University of Phoenix
Nov 10, 2007
Database Implementation Plan for Riordan Manufacturing Riordan Manufacturing has asked our firm, LTB and Associates, to develop a web-based plan to be used as a Business-to-Business web site in order to purchase materials from their vendors. We have examined Riordan’s products and business systems, interviewed Riordan’s employees, and have determined the best course of action to implement the plan. Riordan Manufacturing is a plastics manufacturer based in several locations across the world. With three plants based in the continental US, which are located in Albany, Georgia; Pontiac Michigan; and in San Jose, California, which is the company headquarters. A fourth plant is located in Hangzhou, China will not be part of the plan as they purchase materials locally.
This where we explain how the database will be set up.

The following paragraphs will describe the considerations that Riordan Manufacturing will need to make in implementing the database plan. Where ever it is possible to for our firm to do so, LTB and Associates will make a recommendation on the choice to make. In order to implement the database properly, these recommendations should be implemented in order to offer the tightest amount of security that will be possible. Type of Online Processing
Riordan Manufacturing will need to decide between real-time asynchronous processing and batch processing. Real-time asynchronous processing is applicable when the processing must be performed immediately or when the results must eventually be communicated back to an on-line user. One of the problems with real-time processing is that real-time timers and events are required; they are expensive as the computer resources that are used to raise, maintain and check events. Another problem with timer or even processes is that they create locking problems as they may contend with on-line processes for resources and for access the same data. Batch solutions are ideal for processing that is not real-time event based. Batch processes are data-centric and can efficiently process large volumes of data off-line without affecting the company’s on-line system. Batch processing will allow business function to execute on a periodic or recurring basis; or it can operate over data that matches a given criteria. After studying Riordan Manufacturing’s Inventory and Supply Chain processes, the recommendation is for the company to go with batch processing for replenishment of raw materials for the operations. With daily reporting of the materials used at the end of each manufacturing run as the current method of inventory control, batch processing will work well. While real-time processing works well for online shopping, it is not the best approach to take for this application. Access Privileges
Normally it is not considered a good security risk to grant access to individuals/companies who are located outside of the normal company network and/or firewall. But in order to provide a better integration of the database between Riordan Manufacturing and vendors/suppliers it is necessary to allow limited access. Riordan shall determine the types of privileges to grant to vendors. These privileges include (a) view, (b) insert, (c) update, and (d) delete (logical deletion only). Riordan shall also determine the type of data vendor should be able to access. The data should only relate to the materials that have been used in the daily manufacturing run; materials that have been previously placed on order; and the estimated projections of materials needed for the upcoming week. This will allow both Riordan Manufacturing and the suppliers to determine the present and short-term inventory needs. Bandwidth
