Julie, Why did you register your databases with the US Copyright office? What value do you get from that?

You can copyright code, at any time, or a book (Actually, the text within the book). But an idea or design must be patented.

Maybe no one else ever applied for one? I do have four databases registered with the US copyright office. It seems to me that the copyright office may be a better alternative for this type of application.

I didn't even think such a concept could be patented, since there are built-in provisions in most, is not all, database languages for adding or dropping fields, changing datatypes, etc. I have to wonder what kind of database experience this gentleman has, based on his stated assumptions.

So you see nothing unique in this patent? (BTW, the patent is not pending, but has been granted.) Does this look like "old" technology to you? Is it obsolete technology based on what you describe below as the current methods of implementing changes in the datamodel? Just out of curiosity - So during the time that the new datamodel is being tested in the "shadow" database, am I correct in assuming that the real-time changes that are going on in the production database are also happening in the "shadow" database? That it's a mirror?

Maybe even 60-ies when first flat file/VSAM/hierarchical databases were introduced and used... There were zillion of articles written in scientific areas, there were many research projects - I'd suppose that all these ideas are free to use because they came from open sources as a result of research of many scientists/researchers from many countries and these ideas have been since implemented in many free and commercials DBMSs we use these days... If I did get correctly the subject pending patent idea - it reminds me the principle, which is the core principle of implementing what is called ADABAS - http://en.wikipedia.org/wiki/Adabas ... I'd also note that there is no any reliable company these days which would put its online database into maintenance mode for more that a couple of minutes and only in very unforeseen contexts: I mean when datamodel changes happen they are done on a shadow copy of the main database(s), then these changes all are tested online in what is usually called UAT environments (User Acceptance Test) - when all the tests pass then in a fraction of second the main database is "replaced" with its upgraded shadow copy - e.g. for properly developed ASP.NET 2.0 application switching backends can be done by just fixing one web.config file - even switching from say MS Access to MS SQL to Oracle backend - of course for the latter switch there should be also DAL level code replacement but again it can be done in "hot" mode if that will be requested and paid for the development of such "hot" mode switching... ) -- Shamil -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com] On Behalf Of Rocky Smolin at Beach Access Software Sent: Friday, September 07, 2007 3:48 AM To: 'Access Developers discussion and problem solving' Subject: [AccessD] Database Patent Dear List: A client who is a patent and trademark attorney is interested in opinions on a patent - basically it's a way to update databases on-the-fly by disconnecting the data from the data definition. You can download the patent by going to this web page: http://www.pat2pdf.org/ and entering the patent number 7003524. I guess I'm looking for opinions on whether this is a solution to a problem that exists and whether there is something of value in this approach. I know there's some deep database design talent on this list so I'm thinking this is the best place to start the research. Here's a teaser. From the patent: TECHNICAL FIELD The invention relates generally to databases and, more particularly, to the underlying schematic structure of databases. BACKGROUND Large databases running in publicly accessible environments are notorious for their inability to accommodate change. In today's world of massive access to large databases via the Internet, it is increasingly common to encounter messages to the effect of "database is down for maintenance" instead of the actual data requested. In a conventional database environment, when a change needs to be made to the schematic structure of a database, the data in the database must be extracted from the database in the old structure and re-written to the database in the new structure. If new data were to be inserted into the database while said changes were being effected, it could cause unpredictable effects to the database. Such effects could include corruption of pre-existing data, misapplication of database changes, misalignment of data relative to internal data boundaries, or any number of problems that could render the database effectively incoherent. Such results are untenable in most live database deployments. Conventionally, the most common solution to the problem of updating during changes to the schematic structure is to simply disallow it. Conventional databases also require a tight bind between the data type and the data storage. Users require that the data they request be presented in a manner consistent with the expected usage of the data. For example, a date may be stored in the database as a string of decimal digits (e.g., 20010303), but to present the data to the user in its raw form would be unacceptable. A conventional computer user requires that it be presented in a manner consistent with its usage (e.g., Saturday, 3, Mar. 2001. In order for the date to be presented in a manner consistent with its usage, the database must carry type-related information along with each unit of data. Binding between data and type is conventionally accomplished by organizing the data into metaphorical rows and columns. Rows of data are divided into pre-defined columns, where each column represents a particular data type and/or use of the data. Such data/type binding allows a computer program to make assumptions and inferences about the data appropriate to its type. Additional rows of data may be readily added to a database. However, if a new column is desired in a database, then the database must typically be made unavailable for a period of time so that data can be converted into the new format. Modifications to pre-existing programs would have to be made, along with the requisite testing and debugging necessary to validate any new code. It is also worth noting that in conventional databases there tends to be redundancy in the storage of data. For example, cities, states, zip codes, and telephone area codes may be repeated among a number of rows of data. Such redundancy results in inefficient use of memory. In light of the foregoing, it is apparent that there is a need for a system and method for modifying the schematic structure of a database without making the database unavailable for the entry of new data. Preferably, such a system and method would, among other things, also minimize redundancy of data in a database. SUMMARY The present invention, accordingly, provides a database in which an application program accesses data stored in a records data set (RDS) and a categories data set (CDS). The RDS contains at least one RDS entry having a data field configured for representing data. The CDS contains at least one CDS entry configured for being associated with at least one RDS entry and having at least one data type field sufficient to describe the type of data contained by the at least one associated RDS entry. The invention thus provides a database whereby data is isolated from its definition, thus avoiding the problems associated with the rows-and-columns model enumerated above, and permits the underlying schematic form of the database to be changed based on modifications to the CDS, without requiring any actual changes to the schematic structure of the RDS or the underlying database. By virtue of this same isolation it is also possible to reduce data redundancy with varying levels of granularity and create an object-oriented data model.
