(originally, i had just cut-and-pasted the notes into this email message. then i decided to edit out the company-specific pieces. as i was editing out those pieces, i started updating the notes to incorporate what i've learned since i originally wrote those notes. in the end, this turned into a completely new write up. things sometimes get away from you. hopefully, i haven't wasted too much time and someone will get something of value out of this.) first things first: my experience has been primarily with Microsoft's SQL Server. everything that i've read suggests that, for the most part, they should generalize to other high-end relational databases such as Oracle and Sybase. they'll generalize less to mid-range relational databases such as PostgreSQL. and, of course, they will only generalize to a limited extent to non-relational databases such as FilePro, Access, and MySQL. (and i don't care what people say, MySQL is not a relational database. it's a fine product -- i use it myself -- and it has relational features. but it's not a relational database.) benefits of normalization: A. data integrity the primary thing that normalization gives you is data integrity. with a fully normalized database design, you're not only assured that your transactions will complete or rollback, you're also assured that inserts, updates, and deletes -- that is, any type of modification to the data -- can't compromise your data. to my mind, it is this latter attribute that is the central benefit of relational databases. there are a variety of programmatical ways to check that a transaction has fully committed. but only a fully normalized database with referential integrity can guarantee the absence of insertion, update, and deletion anomalies. B. data retrieval many people will tell you that it's more difficult to build queries against a fully normalized database. to a certain extent, that is true. a fully normalized database will have many tables, each with a handful of columns. to retrieve any single piece of data, then, requires joining together multiple tables. the key here then is simply to learn SQL -- SQL was specifically designed to facilitate the retrieval of data from a fully normalized database. the problem is breaking out of the procedural-oriented programming mentality that most of us are familiar with. indeed, SQL is set oriented which makes it a whole new ballgame. i've found that with a fully normalized database, i can retrieve any piece of data with a single query. and, generally, the queries aren't that complex. this isn't to say that i never make use of multiple-statement queries; indeed, i often do. but only under particular circumstances such as calculations where i'll often need to write one statement per variable in the calculation. the important point, however, is that i never need to run multiple statements to retrieve a given piece of information. C. performance anytime you read about normalization, you'll read that normalization decreases performance. the idea is that joins between tables are expensive; since queries of a highly normalized database tend to require joins between a greater number of tables, performance will suffer. the solutions, then, is careful denormalization of the database. my experience is that this isn't true unless your tables have millions of records. a fully normalized database should exhibit greater performance because (1) your queries and shorter and simpler (as discussed above), (2) your tables have fewer records since duplicate information has been eliminated through the normalization process, and (3) indexes are more efficient because each table only contains a limited amount of non-redundant information. this last point can't be overstated as indexes are a -- if not the -- primary key to performance. with a properly normalized database, your queries will almost always hit the clustered index. disadvantages of normalization: A. normalization procedures despite what i may say sometimes, the proper normalization of a database is a challenging process. there are CASE tools which purport to assist in this process but i've never been particularly impressed with them. i do all of my normalization by hand. the risk of course, is that an improperly normalized database can cause significant problems. i once over-normalized a database such that the query ended up returning false data. pretty impressive, i thought. furthermore, planning is even more important because databases don't lend themselves to rapid development. the unix philosophy of "build a prototype early" is a sure recipe for disaster when applied to databases. i know this from a very, very painful experience (which i'm still living with today. 'nuff said). i now spend a great deal of time researching my projects before i even begin the design. B. database restructuring proper database design is also important because it can be very difficult to modify the structure of a database after the fact. modifying a properly normalized database is easier than modifying an improperly normalized database (primarily because you're more confident in the integrity of your data) but modifying a database structure is never pleasant. database restructuring is also problematic since the database generally serves as the foundation of an larger application. changes to the database risk breaking the application. (you can alleviate some of this risk by implementing abstraction layers between the database and the application but it's an imperfect solution) C. data insertion and maintenance while a fully normalized database makes it easy to retrieve data, it can be a serious pain in the ass to insert new records and update existing records. i have a handful of tables with inter-table dependencies (i.e., they have referential integrity on themselves). these tables are locked down so tightly that you can only insert, update, or delete data by acting on all related records; it's impossible to update individual records. this is an extreme example (i've never seen it anywhere else) but it does occur. that data maintenance is tightly regulated isn't a bad thing -- it guarantees the integrity of the data. but it definitely can be a pain. one final thought about relational databases -- they're not always appropriate. i've come to believe that relational databases are used far more often than they need to be. when people come to me asking about implementing a database system, more often than not, i end up recommending against implementing a relational database. for many applications, text files are perfectly suitable. if your needs are limited, the relationships between your data are not particularly complex, and your queries are straightforward, MySQL or FilePro is the way to go. and if you find that you're going to need to embed a lot of complex business rules into your database structure, take a look at an object-oriented database system. many of today's complex web applications -- particularly banking and high-volume community sites such as Slashdot -- would be better served by an OODBMS. unlike an RDBMS which segregates the data from the application, in an OODBMS, the data is the application. unfortunately, at present, object-oriented database systems tend to be quite expensive; and i'm not aware of any open source projects.

They discuss matters against the Linux kernel mailing list, and diff against kernel releases and interim patchlevels as announced on that list. Frequent releases prevent one's development targets from being too far out of date, and the situation is slightly chaotic, but on the whole, it's tended to be productive chaos. Various parties have suggested formal source-control regimes, which Torvalds has thus far declined to adopt -- for specific reasons which one can look up, but I haven't done so for this post. There are unofficial CVS archives, notably the one kernel hacker David Miller maintains at vger.kernel.org . Please see http://www.tux.org/lkml/ , for lots of details. Patches get adopted through a somewhat Darwinian process on the mailing list (whose name you will often see shortened to "lkml"). There is no formal structure of "committers". The process is often criticised as allegedly too unstructured -- notably by other groups that just chance to use formal source control, and have clear boundaries between insiders and outsiders according to access permissions. Discussions of the matter often turn out to be _not_ discussions, but rather attempts to foment flamewars between partisans. I have no interest in the latter and no investment in any position; I'm just trying to answer your question as best I can. -- Cheers, "Transported to a surreal landscape, a young girl kills the first Rick Moen woman she meets, and then teams up with three complete strangers rick at linuxmafia.com to kill again." -- Rick Polito's That TV Guy column, describing the movie _The Wizard of Oz_
