Beginning in September, Urban Molecule rolls out Community, a new listings section that includes indie coffee houses, indie bookstores, and galleries around the city, as well as a virtual guide to art on the Internet and, of course, your favorite artists and writers here at UM.

As artists, we need to know what’s happening in our community, but as life ramps up to light speed and our favorite joints get run out by those big bad corporations, the coolest places to work and mingle sometimes get lost in the shuffle. Who has the time to look for new hangouts? No worries! UM Community will serve it all up in one place, so you can know where to go online, as well as offline, to keep the arts thriving. And it doesn’t end there. You’ll be able to interact with your favorite coffee shops, bookstores and galleries by leaving comments on their pages and rating your experiences.

The Molecule believes in community. If we didn’t, we wouldn’t be here. It’s that simple. And our community is made up of what artists and writers find important in the twenty-first century city. How do you connect with others like you? Where do you go to feed your brain? What do you take for that insatiable thirst for art? Come mid-September, UM Community will give you all that and more. Just check out our new “community” tab in the top navigation.

UM Community is more than a list. It’s life. City-style.

e Discovery is a concept that is much sought after in large multinationals that hold vital employee and business data. If data is to be bound to its legal requirements and also retrieved at less cost, then a proper solution has to be devised. Generating reports out of such data is also a necessity. Solutions for eDiscovery help scale up to the business size.

When on the lookout for archiving solutions, one basic attribute is to see that all the legal requirements of the data are intact before and after archival. This is what provides integrity and authenticity to the data that has to be retained for a long time.

But wouldn't it be really cool if there was a database in wich everyone uploads their images that get stitched together so we could photomap the entire world? And then we connect it to Google Earth! Think of the possibilities!

Application retirement helps rganizations to reduce cost while maintaining access to the data either through the creation of a common data store or by migrating data into an existing enterprise application. By utiliziong Application retirement organizations can improve operational efficiency, reduce costs and ensure that data retention requirements are met.

Application retirement reduces the number of applications within the IT infrastructure; DBAs can concentrate on maintaining critical business applications with the highest value to the organization instead of compiling data from disparate sources.

With the Data Archiving solution for Oracle, organizations can create and deploy effective and consistent policies for managing, securing and storing data from a single policy console. The result is improved application performance and availability through smaller production database sizes, shorter backup and recovery times, reduced labor costs associated with production and test system maintenance and lower storage and infrastructure requirements and costs.

Most experts conclude up to 80% of production data is no longer mission critical, using database archiving reduces overall storage costs while maintaining access through the native application. The result is a highly stable production environment and streamlined performance that leads to higher productivity and a positive impact to your organization's bottom line.

Following my philosophical train of thought about personal and intellectual development, I decided to start with the first of the three certifications on the pathway to becomming a DBA -- an Oracle Certified Associate (OCA), which comes before the Oracle Certified Professional (OCP). The Oracle Certified Master (OCM) is the ultimate of these certifications, and grants an individual to call themself a Oracle DBA which carries a lot of weight behind it. From the look of things, they are in great demand and will not cease to be.

To train myself, I decided to be practical with my learning. I am a kinetic learning, from all the tests I took, and from my own personal experiences and observations.

After several tries to install Oracle on my Fedora 9 box, I, somewhat, abandoned the installation due to the huge work load I was expected to undergo just to run a database server. I do not have all this time. I am a college student with many other projects and goals in mind. So, I cheated, and downloaded an old copy of an Oracle database (10g) running in a VMWare environment under CentOS. I give much credit to the person who thought about emulating 10g, because setting up the Operating System's environment variables, kernel configuration, network interfaces, and installing all required software libraries needed to run OUI (Oracle Universal Installer) can be quite cumbersome and overwhelming at times, for Linux newbies, and lazy college students that have to time on their hands due to class assignments, senior design research, and personal projects.

The first step I took in getting off the ground with this was to uncompress the package: VMWare-CentOS-Oracle.zip into an accessible folder on my local disk. After the extraction, I fired up VMWare player (which is now free for download), clicked on OPEN to browse for my virtual image to load, and selected the proper file that initiates this process. I was looking for a .vmx file, and, sure enough, it was parked in "VMWare-CentOS-Oracle" folder as sles.vmx in my case.

After having the image load up and bringing up a login interface, I had nowhere to go but consult the documentation that came with it. Consequently, I opened up the "howto.doc" instructions file and was told that the two available accounts were "root", with a password set as "root", and "oracle", with a password set as "oracle" as well. I logged in as user oracle. And was greeted by an XFCE desktop interface. I was so happy!

I looked around, then glanced over the TERMINAL/console icon on the taskbar panel and proceeded on clicking on it. I was given the following option to:

[oracle@localhost ~]$
Choose your Oracle Home
1) Server 10.2 EE: /u01/app/oracle/product/10.2/db_1
To start/stop database, listener, new EM console
2) Client 10.2:  /u01/app/oracle/product/10.2/client
To run Java EM and other tools
1

Your current environment:
ORACLE_BASE = /u01/app/oracle
ORACLE_HOME = /u01/app/oracle/product/10.2/db_1
ORACLE_SID  = DB1
You can change your environment running:
. /home/oracle/.bash_profile

It didn't matter. I just wanted to play, so I went into SERVER mode. As you can see, my choice was 1. Yeah!

To get things on the way, I started all necessary software for the Oracle database to run on my machine:

[oracle@localhost ~]$ lsnrctl start

The command completed successfully!

I also started SQLplus with the /NOLOG option which establishes no initial connection to the database:

[oracle@localhost ~]$ sqlplus /NOLOG
SQL*Plus: Release 10.2.0.4.0 - Production on Thu Aug 21 10:22:22 2008
Copyright (c) 1982, 2007, Oracle.  All Rights Reserved.

I then proceeded to connecting to the database as SYSDBA (the highest of the administrative roles):

SQL> conn / as sysdba
Connected to an idle instance.

Now, I decide to fire it up using:

SQL> startup;
ORACLE instance started.

Total System Global Area  314572800 bytes

Time for something else, since the database has been started:

SQL> exit

------------------------------------------------------------------
Logs are generated in directory /u01/app/oracle/product/10.2/db_1/localhost_DB1/sysman/log

And, now, the most fun part is where I went ahead and did logged into the administrative panel through the HTTP server setup by Oracle. The hostname is: https://localhost:5500/em It brought up the following page where I logged in as "sys" with password "oracle" as a "SYSDBA":

Shortly after, I browsed around what this portal had to offer to the SYSBA, and found the following information I could retrieve from the schema:

And, finally, I decided to see what the Administration tab had to offer me, so I navigated to it, and found the following tasks I could accomplish graphically:

[caption id="attachment_9" align="aligncenter" width="564" caption="DB Admin Section [I"]"][/caption]Also, under this were more options from this administrative arsenal of tools:

[caption id="attachment_10" align="aligncenter" width="564" caption="DB Admin Section [II"]"][/caption]And, lastly, from the same category was this:

[caption id="attachment_11" align="aligncenter" width="562" caption="DB Admin Section [III"]"][/caption]
Or, manually, these tasks can be done using the command line from:

[oracle@localhost ~]$ cd /u01/app/oracle/product/10.2/client
[oracle@localhost client]$ ls
assistants   has               jdbc     nls          oui       root.sh      wwg

Next time around, I will show how I create databases and tables using oracle. And will perform some very basic selection, insertion, updating, altering, and removing of data from the schema.

That's it for now, boys and girls!

So I found myself at Railscamp UK on the weekend without a ruby+rails topic to really talk about during the presentations part of the camp. I'm still a noob wrt. Rails, you see. Realising that CouchDB is relevant to most web developers because most developers deal with document-based content at some point and that Ruby, Rails, and Erlang are kindda like the current bratpack (in a John Hughes-sense) of computer languages, I thought it would be a great little topic for a 15-minute presentation.

So I thought I share the slides and some of the code I hacked up on the weekend. First of all the slides...

(click me)

You can play about with some sample code that was expanded upon after the presentation. Here's a little helper class to interface into CouchDB using JSON and HTTP:

[sourcecode language='ruby']
require 'rubygems'
require 'httparty'
require 'json/pure'
require 'find'

class CouchHack
include HTTParty
base_uri 'http://127.0.0.1:5984'
format :json

def update( path, document )
options = { :body => JSON.generate(document) }
puts self.class.put(path, options )
end

def get(path)
self.class.get(path)
end

def create(db_path, document )
options = { :body => JSON.generate(document) }
self.class.post(db_path, options )
end

def define_view(db_path, design_doc_name, views )
document = { "views" => views }
options = { :body => JSON.generate(document) }
self.class.put("#{db_path}/_design/#{design_doc_name}", options)
end
end
[/sourcecode]

Once that's in place you can use the CouchHack class by defining a view like so:

[sourcecode language='ruby']
ch = CouchHack.new
gem_views = {
  "small_gems" =>
    {
      "map" => "function(doc) { if (doc.length < 3000) emit(doc.path, doc) }",
    },
  "large_gems" =>
    {
      "map" => "function(doc) { if (doc.length > 3000) emit(doc.path, doc) }",
    }
}
ch.define_view("/railscamp", "gems", gem_views)
[/sourcecode]

This design document, as is its known in CouchDB parleance, defines two views (think 'baked queries'), to return a list of small gems - those less than 3000 bytes - and a list of large gems - those larger than 3000 bytes.

So where do these gems come from and how do they end up in CouchDB ? That's what the next and last little fragment of Ruby code does.

[sourcecode language='ruby']
Find.find('/Library/Ruby/Gems/1.8/gems/' ) do |f|
  if File.file?(f) and f.ends_with?('.rb' )
    begin
      gem_contents = IO.read(f)
      gem_document = { "path" => f, "length" => gem_contents.length, "content" => gem_contents }
      ch.create( "/railscamp", gem_document )
    rescue Exception => bang
      puts "Skipping #{f}"
    end
  end
end
[/sourcecode]

So what happens is that the last little fragment traverses the filesystem starting at /Library/Ruby/Gems/1.8/gems/ and looks for *.rb files. When it finds one it POSTs that whole document including the file length to CouchDB, where it becomes part of the resultset of one of the pre-defined views. These views can be accessed through the following two URLs (assuming the 'railscamp' DB was used).

• http://localhost:5984/railscamp/_view/gems/large_gems
• http://localhost:5984/railscamp/_view/gems/small_gems

Feel free to post comments and ask questions.

Enjoy.

P.S. and if you get a chance to go to a *camp conference, GO! They're an amazing format and you'll learn soooo much!.

Estamos virando oficialmente o blog do Database, então vamos atualizar nossos caros leitores das últimas novidades do duo. Primeiro, o remix da dupla para o projeto The Brighton Port Authority do eterno Fatboy Slim, Norman Cook. Na faixa “Toe Jam” o Inglês vem desbravando novos horizontes com uma ajudinha dos díspares David Byrne e Dizze Rascal. O Database não deu moleza e desconstruiu a faixa e abusou dos synths e muito peso. A original tá aqui acompanhada do clipe, que por sinal, é um dos mais divertidos do ano. Ess remix sai oficialmente no single do BPA.

Shipping databases with live data offiste is and always has been a big No No for me.  I expressed this to the individual to which they said, "I know but it was encrypted."  Lets think about that for a minute.  The database being encrypted protects it in transfer, but that is about the extent of it.  At that point you are relying on someone else to take the necessary precautions to ensure nothing happens to the data.

• You have no control over her machine which could be infected every which way from Sunday.
• You have no control over who she shares her computer with.
• You have no control over whether she keeps the data encrypted.
• You have no control over whether she carries that data with her on the unencrypted laptop.
• You have no control over whether she makes backup copies on USB drives or other media.

You get my point....

I think this raised an eyebrow because it prompted a phone call to the consultant to ask some of these questions.  Turns out she never really thought of this and was actually very surprised to learn that is she lost her laptop anyone with access to the machine could access the data.  That level of misunderstanding on how this stuff works makes me a little nervous about entrusting her with data of this nature to begin with.

How about you?

Remember when the FBI couldn't search their own records on "terrorist" and "flight school" at the same time?  The Department of Homeland Security seems to be making progress at remedying that:

The federal government has been using its system of border checkpoints to greatly expand a database on travelers entering the country by collecting information on all U.S. citizens crossing by land, compiling data that will be stored for 15 years and may be used in criminal and intelligence investigations.

Officials say the Border Crossing Information system, disclosed last month by the Department of Homeland Security in a Federal Register notice, is part of a broader effort to guard against terrorist threats. It also reflects the growing number of government systems containing personal information on Americans that can be shared for a broad range of law enforcement and intelligence purposes, some of which are exempt from some Privacy Act protections.

The views on this will be predictable.  I've had students from government agencies on all sides of this issue, and with widely varying views.  It may be time to acknowledge that the integration of these databases is not a matter of "if", but of "when".  Taking that view at least allows organizations and their stakeholders to make informed decisions about the real issues.

You will notice the offending underage gymnasts name in yellow.  This document clearly states that the birthday is Jan. 1, 1994.  That makes her 14, not 16 as the Chinese claim.  As the Stryde Hax blogger also states, I could care less the age of the gymnast.  I am simply supporting this due to what seems to be deliberate attempts to remove this information from public databases.

O Oracle Database Gateway para ODBC (DG4ODBC) permite a construção de soluções heterogêneas que transparentemente integra ODBC com bancos de dados Oracle. O ODBC fornece uma interface padrão para bancos de dados relacionais, incapsula aplicações de banco e traduz os comandos especificos do banco de dados de origem em algo que possa ser entendido pelo banco de dados Oracle. O uso do ODBC na ligação entre o banco de origem e o banco de dados oracle, faz com que o DG4ODBC não esteja vinculado a um especifico tipo de banco de dados. Esta arquitetura flexível possibilita a convivência com qualquer banco de dados compatível com o ODBC.

Usando o DG4ODBC, você pode imediatamente rodar suas aplicações oracle, tanto construídas pela Oracle ou por terceiros, para acessar informações via ODBC de bancos de dados oracle e não-oracle. As aplicações não necessitam ser reescritas ou reconfiguradas. O DG4ODBC não causa impacto nas aplicações, você pode usufruir das vantagens de uma arquitetura multi-plataforma na integração de diferentes tipos de bancos de dados.

O DG4ODBC é parte integrante do Oracle 11g, sem custo adicional, e suporta Oracle 11g e Oracle 10g. Para integração de bancos dados ODBC em versões anteriores ao Oracle 10g, é necessário customizar o banco.

Le banche dati sono dei grandi archivi riguardanti un determinato argomento, ovviamente nel nostro caso riguardano argomenti biologici. Le banche dati oggi esistenti (in campo biologico) saranno un migliaio, e viene catalogato praticamente di tutto, dal genoma umano alle malattie, passando per geni, Rna, polimorfismi e chi più ne ha più ne metta.

Alcune di queste banche dati sono state sviluppate dall'EMBL-EBI, altre dall'NCBI, contengono milioni di voci, e sono utilissime. Le banche dati possono essere mantenute e controllate da persone, queste di solito risultano molto ben curate e poco ridondanti. Altre invece possono essere mantenute da software, quindi sono aggiornate molto velocemente ma molto ridondanti (per ridondante si intende che la stessa informazione è contenuta più volte)

Esistono 3 banche dati che sono dette primarie, poichè contengono le informazioni riguardanti il Dna. Tutte le altre banche dati (proteiche, di polimorfismi, di malattie) sono collegate a queste. Due di queste sono EMBL datalibrary e la GenBank. Fra queste due banche dati c'è un continuo scambio di dati, per cui tutte le informazioni che potete trovare su una, le trovate anche sull'altra.

Esistono poi database secondari, che contengono sequenze proteiche: Swiss-prot, TrEMBL e PIR. Swiss-prot è curata manualmente, per cui è poco ridondante ed è ricca di informazioni (ed è un database che adoro!!! :D ). TrEMBL nasce grazie alla traduzione automatica dei geni presenti in EMBL datalibrary, per cui alcune delle proteine predette possono non esistere nella realtà. PIR è l'equivalente nato dal laboratorio americano. Nel 2002 nasce un database integrato fra Swiss-prot, TrEMBL e PIR chiamato UniProt.

Allo stesso di UniProt, varie banche dati riguardanti famiglie proteiche, domini proteici, motivi sono state raccolte in InterPro. In particolare Pfam (famiglie e domini proteici), PRINTS (motivi proteici), PROSITE (famiglie, domini e motivi proteici curati dagli stessi di Swiss-prot).

Infine esistono banche dati delle strutture tridimensionali delle proteine come PDB, le cui coordinate di tutti gli atomi di una proteina sono ricavate sperimentalmente, oppure come ModBase invece, le cui strutture tridimensionali sono solo previsioni...ma possono essere utili lo stesso...

Spero di riuscire ad entrare nel dettaglio di tutti questi database...

Infine ho per voi un'immagine riassuntiva di tutti i database:

Bè...se ho sbagliato qualcosa segnalatemelo! Se avete voglia di aggiungere qualcosa...fatelo! :D

Alla prossima...

MySQL, altı milyondan fazla sistemde yüklü bulunan çoklu iş parçacıklı (multi-threaded), çok kullanıcılı (multi-user), hızlı ve sağlam (robust) bir veritabanı yönetim sistemidir.

UNIX, OS/2 ve Windows platformları için ücretsiz dağıtılmakla birlikte ticari lisans kullanmak isteyenler için de ücretli bir lisans seçeneği de mevcuttur. Linux altında daha hızlı bir performans sergilemektedir. Kaynak kodu açık olan MySQL’in pek çok platform için çalıştırılabilir ikilik kod halindeki indirilebilir sürümleri de mevcuttur. Ayrıca ODBC sürücüleri de bulunduğu için birçok geliştirme platformunda rahatlıkla kullanılabilir.

Geliştiricileri, 500′den fazlası 7 milyon kayıt içeren 10.000 tablodan oluşan kendi veritabanlarını (100 gigabyte civarında veri) MySQL’de tuttuklarını söylüyorlar.

MySQL, tuttuğu tablolarla çok kullanıcılı sistemlerde söz konusu olan erişim hakları sorununu başarılı bir şekilde çözmektedir. MySQL’in 4.0 sürümü ile birlikte “transaction” desteği, 4.1 sürümüyle birlikte de alt sorgu desteği eklenmiştir.

Ayrıca “veri tutarlılığını (referential integrity)” sağlama işinin programcıya bırakılması tercih edilmiştir, ancak bu bir dezavantaj olarak görülmeyebilir. Çünkü pek çok veritabanı programcısı VTYS’lerdeki veri tutarlılığı’nın esnek olmayan, zorlayıcı bir özellik olduğunu düşünmektedir. ]]> http://dotnetraja.wordpress.com/?p=10 Wed, 20 Aug 2008 14:32:10 +0000 dotnetraja http://dotnetraja.wordpress.com/?p=10 Select * from users where convert(char,createddate,101)='07/29/2008'

Syntax: DBCC checkident (tablename, reseed, 0)

DBCC checkident can reseed the value of the table. For e.g.: our table has 25 records with 25 as last identity. If we want next record to have identity has 35 we need to run following T-SQL

DBCC checkidetnt (tablename, reseed, 34)

Disadvantage: It will violate the uniqueness.

We all know how happy the UK is about CCTV, but apparently they are now planning something very similar to China's Golden Shield Project; that is a humongous database meant to tap all electronical communication in the country. This surpasses the Swedish FRA-law by miles, and the implications on personal integrity and freedom will be very dire. I can't help but think of V for Vendetta.

How does the fight against terrorism justify a development towards a more and more totalitarian state? Let's face the fact, the so called terrorists are winning the fight without even lifting a finger any longer. We're having the work cut out for them.
