| Arnold: 6-Oct-2012 | Ah Kaj, could you put up a shopping list of thing to buy too when you buy a RaspberryPi? | |
| Arnold: 7-Oct-2012 | after running around all week buying additional needed equipment. that sounds like a shopping list comes in handy when purchasing a RaspberryPi, there are some surprises like needing a VGA monitor where the standard videoout on the Pi is HDMI. | |

MySQL 5.0 Adds Features for Enterprise Developers and DBAs
by Ken
North
Baseball legend Satchel Paige is famous for having said
Don't look back, something might be gaining on you." Companies selling
a commercial SQL database management system (DBMS) know its MySQL
that's gaining on them. With an already large installed base, MySQL
is set to attract new users because of the feature set of version
5.0. It includes capabilities for which developers have often turned
to commercial SQL products.
The purposes for which we use personal, mobile, workgroup, departmental,
enterprise and web databases are diverse. Application requirements
are a primary determinant of the capacity and features we need from
an SQL DBMS. For example, a high-volume transaction processing web
site places greater demands on a database than a contact list manager
for laptops and small business servers.
A Web Techniques magazine article, "Web Databases: Fun with Guests
or Risky Business?" discussed features that characterize an industrial-grade
SQL DBMS. It explained SQL security and mission-critical databases,
defined as
"A database is mission critical if its lack of data integrity has
serious consequences, such as causing the loss of customers or even
lives."
Maintaining data integrity is implicit -- that's a prime directive
for a DBMS. The article explained other features that enterprise
developers look for in an SQL platform:
... mission-critical applications require features such as intrinsic
security, transaction journaling, concurrency controls and the ability
to enforce data integrity constraints. Without those features, you
do not have secure, robust databases. Connecting a database to a
Web server adds other requirements, such as a multithreaded architecture
and the ability to do database backups without taking the server
down.
Freeware and PC DBMSs are suitable for certain classes of applications,
but not for high-volume Web sites and mission-critical databases.
In any case, don't bet your business, or lives, on such software
unless you have the source code and the expertise to understand and
repair it.
Since that article appeared in print, improvements to MySQL have
removed the "not ready for prime time" label. Features described
in that article are now available to MySQL users:
* transactions
* concurrency control, locking, SQL standard isolation levels
* intrinsic security
* integrity constraints
* thread-based memory allocation.

MySQL uses separate threads to handle TCP/IP and named pipes connections,
authentication, signaling, alarms and replication. The combination
of threaded architecture and MySQL clustering provides powerful parallel
processing capabilities. MySQL can process transactions in parallel
with separate connections on separate processors using separate threads.
MySQL Milestones
A decade of development has moved MySQL out of the bare-bones DBMS
category, enlarged its user base, and turned MySQL AB into a profitable
company. One of the important milestones was integration of the InnoDB
engine with MySQL 4.0. That upgrade gave MySQL multiple tablespaces,
tables greater than 4GB and support for transaction processing. Other
enhancements included OpenGIS spatial data types and hot backups.
The latter enables a DBA to perform a backup without taking the DBMS
offline. Hot backup software is available as a commercial add-on
for databases using the InnoDB storage engine.
MySQL 5.0, the newest version, is a major milestone. There have been
enhancements to the tool sets, storage engines, types and metadata.
MySQL 5.0 includes features enterprise developers have come to expect
from commercial SQL products.
* capacity for very large databases
* stored procedures
* triggers
* named-updateable views
* server-side cursors
* type enhancements
* standards-compliant metadata (INFORMATION_SCHEMA)
* XA-style distributed transactions
* hot backups.
MySQL has a demonstrated capacity for managing very large databases.
Mytrix, Inc. maintains an extensive collection of Internet statistics
in a one terabyte (1 TB) data warehouse that contains 20 billion
rows of data. Sabre Holdings runs the oldest and largest online travel
reservation system. It replicates 10-60 gigabytes per day from its
master database to a MySQL server farm. The MySQL databases are used
to support a shopping application that can accommodate a million
fare changes per day."

| Henrik: 11-Sep-2009 | BBL, shopping. | |
| Group: !Cheyenne ... Discussions about the Cheyenne Web Server [web-public] | ||
| Robert: 12-Feb-2009 | I want to write a shopping-cart module without any GUI stuff etc. Just a plain shopping cart where you can add, change, remove products and provide a lot of special parameters like handling-fees, etc. Displaying the content of a specific shoppig-cart should work by calling a RSP page, that selects the correct shopping-cart through session ID and just generates a simple table etc. at the right place in a styled web-page. | |
| Dockimbel: 12-Feb-2009 | For storing shopping carts, do you really need a full database engine, REBOL blocks serialized should be enough, no? | |
| Robert: 12-Feb-2009 | 3. Blocks: That's the way I want to go. Using the session ID to store shopping-carts. And than a clean-out run after several days or so. The problem with the session-ID not being a cookie is, that the session is lost if the user closes the browser and later returns. Right? | |
| Robert: 17-Feb-2009 | I run several domains as virtual domains in lighttpd. And I have one document root for Cheyenne. The idea is to be able to add the same RSP page (like a shopping cart) to severl domains without having to duplicate the RSP code pages. | |
| Robert: 18-Feb-2009 | Being able to install web-appliances with a smart and simple integration-interface would be very cool. I'm going to try this with the shopping cart stuff. We will see how it will work. Adding a simple deploying mechanism shouldn't be that hard than. | |
| Robert: 12-Jun-2009 |
I have a problem, that after some running time Cheyenne seems to
get into an unstable state and my REST shopping-cart isn't working
any longer. I got this error in the trace.log, which seems to be

| Maarten: 21-Jul-2009 | Doc, RSP by itself.. I use a version which does set word capturing (do you do that?) and allows page inclusion and context injection with "captured" words on the subpage. Do you do that? Otherwise, a lot of Qtask "the application" is Javascript on the UI calling API services - RSP is of little use there. The main web site... I would actually oppose REBOL. Why spend time there on e.g. a shopping cart when you can take one of the shelf and spend that time improving the real product (the service/application)? | |
| Robert: 13-Oct-2009 | It seems that I somehow get back an old session/id from someone else even I just opened my browser and loaded a page. This problem shows in my REST shopping cart in that I get a shopping cart from someone else. | |
