FIELD OF THE INVENTION
This invention is related to data management systems and managing data objects in a client/server environment where elements of the system may exist on a homogenous computer platform or the elements may be dispersed among a plurality of platforms in a distributed computing environment. Our data management system is particularly useful for use in specialized business solutions which employ our processes and methods, such as for hardware design, software development, inventory tracking, manufacturing, project management, and any related field which necessitates the sharing and tracking of multiple iterations of data objects in a quality controlled environment.
BACKGROUND OF THE INVENTION
In the article entitled “Beyond EDA (electronic design automation)”, published in Electronic Business Vol.19, No.6 Jun. 1993, P42-46, 48, it was noted that while billions of dollars have been spent over the past (then and still last) five years for electronic design automation systems (EDA) and software to help companies cut their design cycle, a huge gulf remains between design and manufacturing. To eliminate the gulf and thus truly comply with the commandments, companies are extending the concept of concurrent engineering to enterprise wide computing. The concept, which calls for integrating all the disciplines from design to manufacturing is becoming the business model of the 1990s. Achieving an enterprise wide vision requires tying together existing systems and programs and managing the data that flows among them. Software that makes that linkage possible is largely in the class known by two names: product data management (PDM) or product information management (PIM). Mr. Robinson, the author, described the experiences of several companies with PIM and PDM, in particular Sherpa and Cadence.
The design of complex parts, such as integrated circuits, computers, or other complex machines in a complete manufacturing operation like IBM's requires computer capability, with computers capable of processing multiple tasks, and allowing concurrent data access by multiple users. The IBM System 390 operating system known as Multiple Virtual Storage (MVS) allows such things as relational database management methods, such as the TIME system described by U.S. Pat. 5,333,316, to be used to reduce design time. The TIME system is used within IBM for the purposes described in the patent during circuit design. However, these prior efforts treated design as directed to an entity and did not achieve the efficiencies provided by the system detailed in our description of our invention, which also can run under MVS, but also under other operating systems. Our detailed description of our invention will illustrate that we have furthered the objects of the invention of 5,333,316 by increasing the flexibility of a number of circuit designers who may concurrently work on designing the same integrated circuit chip and reducing the interference between chip designers. With the prior system, a user (a person, processor or program capable of using data in a relational database) was given a private copy of the master table. Alteration of a row in the user table was not automatically updated in the master table, because a lock mechanism prevented the row update, but that was a great improvement at the time, because no longer did multiple users have to wait for copying of a table each time data from a user needed to be updated. This row locking and treatment of data has become widespread in the relational database field, and it has been enabled for use with multiple instances of a platform even on Unix machines today. We should note that also in the MVS art, there have been proposed various library systems, e.g. those represented by U.S. Pat. Nos. 5,333,312 and 5,333,315 and others which relate to IBM's Image Object Distribution Manager in the ImagePlus product line of IBM, and IBM's Office Vision are examples of systems enabling control of a source document while allowing access by multiple users. Implementation of these patented ideas enable synchronous and asynchronous copying of a document into a folder in a target library. These methods provide for check out of a document and its placement in a target library while locking the document in the source library to prevent changes while the checked out document is out. But these steps are only some of the many things that are needed to bring a product to a release state. Bringing a product to a release state is an object of the current developments relating to design control in a manufacturing setting.
Concurrent engineering is required among many engineers working in parallel and at different locations worldwide. Furthermore, as noted by Oliver Tegel in “Integrating human knowledge into the product development process” as published in the Proceedings of the ASME
Database Symposium, Engineering Data Management: Integrating the Engineering Enterprise ASME Database Symposium 1994. ASCE, New York, N.Y., USA. p 93-100, specialists who are not working directly together are often needed for solving the demanding tasks that arise during the development of today's advanced products. During product development, assistance is required from other departments such as manufacturing, operations scheduling, etc. Even the vendors and customers should be integrated into the product development process to guarantee the product developed will be accepted in the market.
There is a need for integrators/coordinators/model builders and designers to work together to create a next release. Information from different people in different forms must be collected aiming at a final good design. A problem occurring during product development is how to know which people to contact for what kind of information, but that is only one. During all of the process, concurrent engineering, particularly for the needs of complex very large scaled integrated system design, needs to keep everything in order and on track, while allowing people to work on many different aspects of the project at the same time with differing authorizations of control from anywhere at anytime. For the purpose of the following discussion, we need to say that we call our system a “Computer Integrated Design Control System and Method” because it encompasses the ability to integrate CIM, EDA, PDM and PIM and because it has the modularity making it possible to fulfill these needs in a concurrent engineering environment particularly useful to the design of complex very large scaled integrated systems as employed in a computer system itself. The making of these systems is a worldwide task requiring the work of many engineers, whether they be employed by the manufacturer or by a vendor, working in parallel on many complete parts or circuits which are sub-parts of these parts. So, as part of our development, we reviewed the situation and found that no one that we have found is able to approach the creation of “Computer Integrated Design Control System” like ours or employ the methods needed for our environment. Our methods are modular and fulfill specific functions, and yet make it possible to 35 integrate them within a complete “Computer Integrated Design Control System.”
A patent literature review, especially one done with retrospective hindsight after understanding our own system and method of using our “Computer Integrated Design Control System” will show, among certainly others, aspects of DMS systems which somewhat approach some aspect of our own design, but are lacking in important respects. For instance, after review of our detailed description, one will come to appreciate that in modern data processing systems, the need often arises (as we provide) to aggregate disparate data objects into a cohesive collection. These data objects may reside at various levels
