In the context of relational databases, “keys” and “relationships” are fundamental concepts that help in ensuring data integrity, organizing data efficiently, and enabling meaningful data retrieval. Let’s break these down:
1. Keys
A key is an attribute (or a set of attributes) that uniquely identifies a record in a table. Various types of keys exist in relational databases:
Primary Key: This uniquely identifies each record in a table. A primary key cannot have NULL values, and each value must be unique. A table can have only one primary key, which may consist of single or multiple columns.
Foreign Key: This is an attribute or set of attributes in a table that refers to the primary key in another table. It establishes a relationship between two tables. A foreign key ensures records in one table correspond to records in another.
Unique Key: Similar to a primary key, it uniquely identifies each record in the table. The difference is that a table can have more than one unique key, but only one primary key. Unique keys can have NULL values, but the values must be unique.
Composite Key: When more than one attribute is used to uniquely identify a record in the table, such a key is called a composite key.
Candidate Key: Any attribute or set of attributes that could serve as the primary key is a candidate key. It means it can uniquely identify records in the table.
Super Key: It is a set of attributes that, when taken collectively, can be used to uniquely identify records. A super key can have additional attributes that are not strictly necessary for unique identification.
2. Relationships
Relationships in relational databases determine how tables connect to one another and how data correlates:
One-to-One (1:1) Relationship: In this relationship, one record in a table is related to one and only one record in another table. For instance, each employee in a company might have one unique work ID.
One-to-Many (1:N) or Many-to-One (N:1) Relationship: One record in a table can be related to one or more records in another table. For example, one customer can place many orders, but each order is made by one customer.
Many-to-Many (M:N) Relationship: Multiple records in one table are related to multiple records in another table. For instance, students and courses. One student can enroll in many courses, and one course can have many students. This relationship is typically resolved in relational databases using a junction table (or bridge table).
Relationships are typically enforced using Foreign Keys. When a foreign key in one table refers to the primary key of another, it creates a linkage that ensures the validity of the data and maintains referential integrity.
Here’s a few of the meetups I’m going to aim to attend this month. Hope to see some fellow coders there.
PADNUG…
…is having a TypeScript Introduction. There’s a lot of those made up marketing words thrown around in the description such as “Application-Scale JavaScript Development”. Maybe TypeScript is magic, but overall it seems to be suspicious. Also, this talk is about how TypeScript will help you write Windows 8 Apps, so you’ve been warned. The kool-aid will be in effect. If you want to learn more about it, go check out the PADNUG meetup on January the 8th at 6:00pm. Intel Hawthorn Farms 3 (HF3) Campus, 5200 NE Elam Young Parkway, Hillsobor, OR 97124.
Portland Ruby Brigade…
…is having their regular monthly meetup at Crowd Compass. If you want to know more about the topic, material or other information about the user group jump into the Google Group to get started. This is a very fluid and flexible group, sometimes having an open discussion, a presentation or some other type of event. Crowd Compass, 2505 SE 11th Ave, #300, Portland, OR 97202. The location is in the Ford Building, with the easiest access straight in to the Ford Food & Drink.
Portland Riak Users Group…
…will meet at AppFog (as of this time) at 6:30pm on January 28th, more info & address on the meetup page. We have a coder/hacker/databaser by the name of Jeremiah Peschka @peschkaj coming in to tell us about the open source project he and OJ @TheColonial have been working on called Corrugated Iron. Corrugated Iron is a .NET Client for Riak, so holds a lot of potential for .NET shops to get into the distributed database world. So come check out the meetup, we’ll be having pizza and likely a bucket full of beer!
There are others, but these are the events that caught my eye. Check them out, I might see you there and if not, let me know how they go. If you’re looking into some other meetups or events, check out Calagator, the Portland Tech Scene Calendar of events. 🙂
Hope you have a little patience, this blog entry is going to be pretty long. There was a multitude of conferences, more than a hundred pair coding sessions, more cities, hotels and other things as I criss crossed the country helping to knock out projects, code, fire off some open source projects and generally get some technology implemented. It has been a spectacular year. I also could add, it has thoroughly kicked my ass and I’ve loved it.
2012 Coding Projects
In 2012 I’ve taken the healm of the Iron Foundry Project which led to the creation of Tier 3 Web Fabric PaaS. A Cloud Foundry & Iron Foundry .NET based PaaS. From there the project led to an expansion of leading the efforts on the Thor Project, which is a Cloud Foundry User Interface for OS-X and Windows 7. Beyond that I’ve contributed to and participated in dozens of different projects in various ways over the year. I finished up this year by joining Basho in December and thus, joined the Riak & related Basho Projects.
Some of the projects I’ve started, will join or hope to otherwise continue participation in include the following. Here’s to hoping 2013 is a hard core coding and contributing year of excellence!
Many of the Basho Organization’s Projects I’ll be diving into, including work around Rebar, Riak, Docs & a number of others.
Name Factory – a project I’ve started a while back of Riak + JavaScript around creating massive test data with JavaScript and also using Riak for the storage & searching on that data created.
Criollo – Criollo is one of the most common forms of cocoa, is a native OS-X Cocoa User Interface for distributed systems built on or using Riak.
SpikeOp – This I’ve dubbed the name of the iOS interface for distributed systems built on or using Riak.
I want to use and possibly contribute to Corrugated Iron, the .NET Client for Riak. Prospectively to use for a Windows 8 User Interface for distributed systems built on or using Riak.
Expand on prospective services for Cloud Foundry, either I or efforts I may lead to do this.
…there are others, but they’ll have to be figured out during the course of events. Also, there are an easy dozen other projects I’ll be working that don’t particularly have to do with coding, two are listed below. For an easy way to keep up with the projects I’m coding on, leading, participating in or otherwise hit me up on Twitter @adron or ADN @adron.
Big Project Aims for 2013
Thrashing Code Project – This is sort of, kind of secret. It’s going to happen soon, I have a personal schedule for it and I’ll be releasing information accordingly when the site and twitter account goes live.
Tour Triumvirate – I intend to plan, and hopefully will take at least 2 of the three tech tours I setup. More information will be forthcoming, but the original notion is outlined in the blog entry I wrote titled “The Adron Code Tour, Let’s Hack, Bike and Talk Hard Core Technology“.
Books I’ve Read in 2012
All of these I’ve either read or re-read in 2012. I set a goal at the beginning of last year to get my ass in gear when it comes to reading. A focused, get it read, understood and learn approach. I think I did pretty good overall. Not a book a week, but I’m getting back in gear. Considering my best year of reading was 100+ books, it might be a difficult to reach that again since I’m a working citizen, versus a child with plenty of time on their hands. But, it’s good to have goals. 😉

My 2012 Coder’s Year in Photos
What I’ve put together here is a photo story of the year, hopefully it’s entertaining in some way. With that, here’s a review of the year, cheers and happy new year! 2012 started with one of my last hack sessions as a Seattle Resident at Ruby at Racer weekly meetup.
Ruby at Racer Meetup
Meanwhile some of my last views from Russell Investments. Absolutely beautiful, epic and awe inspiring views of the Puget Sound from the Emerald City of Seattle.
View from Russell Investments Seattle Headquarters, stunning!
Then a fitting image, from the business meeting floor of the same building, the settings sun for my departure.
Overlooking the Puget Sound, Japanese Garden in the forefront from the Russell Investments Building in Seattle.
February of 2012 kicked of with my return to Portland, Oregon. Stumptown regularly welcomed me back more than a few moments.
Stumptown Morning Brew
One of the first meetups I attended back in Portland was the DevOps Meetup.
DevOps DevOpers Hanging around pre-meeting at PuppetLabs in Portland.
That DevOps meetup just happened to have a session on one of the code bases I was working with, Cloud Foundry.
Cloud Foundry preso on how the pull requests and such where going to be built into a process, which still today is rather cumbersome for community involvement. However, it’s still moving forward, albeit at a slower pace than it could if it was streamlined around github instead of github being an “end point” read only repository…
While my move consisted of many a couch, as I just couch surfed for the first 45 or so days I was back in Portland, I finally moved into a place at the Indigo in downtown.
My New Place, priorities as they are my system sits in the corner ready for use.
The new system, albeit a great Christmas present from 2011, became the defacto work system of 2012 and remains one of my top machines. Mac Book Air w/ 4GB RAM, i5 Proc, 256 GB SSD. Not a bad machine.
2011 Mac Book Air, settled into it’s workspace cradle.
A view from on high, looking down upon the streets of San Francisco from the New Relic Offices. Thanks for the invite and the visit, it was great meeting the great team at New Relic San Francisco!
New Relic San Francisco View
Getting around on my first trip to San Francisco of 2012. Thanks to John, Bjorn, Bill, John and the whole team in Portland and San Francisco for the invite. Great talking to you guys.
MUNI Streetcar FTW!
On the same trip it began pouring rain as I’d never seen before in San Francisco. I sat by Duboche Park, staying warm and away from drowning! Arriving outside was one of the MUNIs that eventually I was rescued by from the torrential floods and returned to downtown, dry and intact!
MUNI to the rescue on the torrential downpour of the year in San Francisco.
…and Julia thanks for the tour around San Francisco and the extra tasty lunch at EAT!! Good times!
Eating at the EAT sign!
Amidst all these images, I threw together some into a collage. There are a number of awesome coders & hackers of all sorts in these images. Shout out to Jerry Sievert, Eric Sterling,
Snikies, a collage I made!!!! (This one you can click on for a full size image)
…and alas I’ll have another zillion images and such as we all roll into 2013 and onward. Cheers! For some more new years posts I’ve found useful check out this list, which I’ll be adding to over the next few days.
This week, the first thing I did was give a solid read to Mark Phillip’s Blog “themarkphillips” (@pharkmillups). Here’s a break down of some entries I found really interesting and helpful in getting kick started here at Basho (or just really a good read in and of itself):
Two Anecdotes About Community From JSConf and NodeConf – This is a great one, two anecdotes that I’m all “hell yeah” about. The entry caught my eye for the obvious reasons that the whole great team behind JSConf & NodeConf, I always have to read about. Mikael, Chris and the whole lot of Noders are a great crew of people, throwing absolutely great conferences. The two anecdotes; “You Want Your Users To Hug You” and “Meeting People In Real Life Never Gets Old And Is Incredibly Valuable”.
Another great entry revolved around putting together RICON 2012. See my other entries “RICON2012 Shreds the House!” and “RICON 2012 Photos” for more on RICON. This entry really lays out ground work for the mission Mark Phillips, Tom Santera and the rest of the team I’ve joined at Basho have to grow the community that works with, around and building distributed databases and systems.
The latest entry, the entry key to what I’m tackling, is the “Month One for Technical Evangelists at Basho“. This leads me to the next blog & entries and material I needed to dive into.
The next blog I gave a good review of was the Basho Blog.
Riak Cloud Storage with Multi-Datacenter Replication – this blog entry outlines the release of, well, what the title says. This release though, is a pretty big deal. The storage is already S3 compliant, a huge benefit in the first place. The entry goes into some detail about the full and realtime sync capabilities of the system. However if you’re really interested in this there’s more to dive into – so ping me or jump on the Basho mailing list and strike up a conversation. We love talking about this stuff at Basho, so don’t shy away from throwing some conversation our way.
The next blog entry that caught my attention, since some of my first demoes are going to be JavaScript, Node.js and Riak, the project around Riak.js getting a fresh start was a relief to read. I’ll admit, I read it when the blog entry was published. 😉
One last entry I read, then dived into the content that it links to is the “Building Apps on Riak” content and use cases blog entry. It links to the Basho Docs (see below) and use cases page.
The last two major things that I read, which are really important in the field of distributed databases and also having a work culture that seriously rocks. These two papers are the Amazon Dynamo Paper and the Valve Handbook.
The second thing I wanted to do was get Riak setup on my local machine to play with. I’d setup Riak a few times before in a multi-node cluster using Tier 3′ s Blueprint Technology to automate the process. This time however I’m taking the vantage of installing it locally for use. So what’s the steps? Well, it’s pretty straight forward. First however, I wanted to synch up my first install experience with the Basho Docs. Since the documentation is actually available via your standard open source repository on github, the Basho way, I wanted to get a local running copy of it.
Basho Documentation
I wanted to business, not just to read but also to contribute back to the basho_docs. This isn’t just some filler docs either, they’re actually really useful and well written. In other words, it’s solid, updated and well maintained documentation.
I forked the basho_docs to my own repo and went to work setting it up. Everything was going great until I stumbled into blockenspiel, or so I thought it was blockenspiel. Thus, the adventure of crazy new machine forgetfulness begins.
Breaking blockenspiel
I’ve spent a couple hours trying to get middleman working for the basho_docs project. Why did I spend a few hours working on this? Well the obvious one is I wanted to get the docs up and running locally, ya see, I intend to contribute back (want to jump into them too, hit up the github repo). While I was getting these installed I made a few mistakes and ran into a few issues. Here’s the story.
The first thing I forgot was to install rvm. The basho_docs project uses rvm and I highly suggest you use it, or something like it. In this case the project has specific settings you definitely want. The simple reason I didn’t have it is that I’d forgotten that I hadn’t installed it on my new Mac Book Air! Doh! Easily fixed via https://rvm.io/. While there I also installed the Jewelry Box App, it’s pretty decent, but you’ll still want to dive into the command line where the real power is.
So with that all good I got through the next few steps.
[sourcecode language=”bash”]$ gem install bundler

At this point, the install seemed to be going great, and then BOOM, this happened!

Ok, so maybe I shouldn’t have used sudo, but wasn’t sure what the permissions issue was in the first place. Yeah, that’s a bad idea just to barge ahead, but sometimes you gotta just move on things. Maybe that was or wasn’t the issue. I didn’t know at this point so started to do some research.
The first thing I realized, was barely anyone had run into this issue. I did however find two things that seemed like they may be the root cause of this blockenspiel problem.
So which native extension did I need to install? I was missing it for some reason. Then I dug around a little more and discovered this in one of the logs.

Hmmm, dammit, new machine mistake again. I needed a C compiler ASAP! Opening up XCode I immediately got this fixed by installing the CLI tools. These tools include about a zillion things I obviously needed, including the LLVM Compiler, Linker and the universally needed Make.

Ok, I finally got that installed and moved forward again. Pulled down the bits, and ran smack into the problem again. The blockenspiel lib can’t build the native extension. Ugh! However this time I got a slightly more useful error message at least.

My first thought was, WTF didn’t I just install the developer tools?
Went digging for this problem and found this interesting and likely related Stackoverflow Entry “”. One of the suggested solutions would be found in executing the following commands. As I read this I realized it wasn’t the marked answer, but I needed MacPorts so I downloaded MacPorts! A quick few seconds later I grabbed it and tried out these commands just to at least get things updated.
[sourcecode language=”bash”]
sudo xcodebuild -license
sudo port upgrade outdated
sudo port install apple-gcc42
sudo rvm reinstall 1.9.3
[/sourcecode]
At this point, still no go. I was getting pretty pissed. At least I was getting all these things setup on my machine, but seriously, this should NOT be this hard. The next thing I did was also update my Ruby Gems, as another place on the web suggested doing that. I tried installing middleman again.
At this point I was a bit frustrated, sat back and figured, I’ll give it a go in a while. Well after a few hours to let things sort out in my head, I picked up a completely different laptop. My Mac Book Air I’ve had and been using for over a year now. I opened up iTerm2 and through these commands in bash:
After all that, it boils down to some stupid machine load issue. So I’ll come back to fixing that machine some other time. For now, it was finally time to move on to other things. But that’s a gist of week one, and week two will be starting in just about 47 minutes. Next week I’ll be diving in a bit more to all of these things plus some actual installation, setup and related skill with Riak. Until then, cheers.
Alright, just for fun I’m kicking off a new blog series. I’m going to publish a new “Deploy a Framework Friday” each week for about the next, well, bunch of weeks. There are a TON of frameworks that are available on PaaS Technologies.
This first entry I’m going to implement a simple Sinatra app with Ruby. Nothing fancy, simply a hello world and the respective deployment to a Cloud Foundry PaaS.
First, let’s whip out the super complex code (right, this isn’t complex, I just like sarcasm). The hello.rb file I created.
[sourcecode language=”ruby”]
require ‘sinatra’
get ‘/’ do
"Hello World!"
end
get ‘/route’ do
"Hello from a route URI!"
end
[/sourcecode]
Next add a Gemfile & respective Gemfile.lock as such.
That does it. Yeah, not a whole lot to get started working on a Sinatra Project. For more information on Sinatra check out the main web presence here http://www.sinatrarb.com/.
