Any experienced developer will tell you that soft skills makes the difference, if you want to move up in the ranks … maybe become a tech lead, or software architect.
Our culture used to idolize the cowboy. That loner who does things his own way and to hell with the consequences. He doesn’t say much unless he’s telling people what’s what, and rides off into the sunset with everyone all the better for having come into contact with him…
And what did we used to say about anyone who didn’t automatically strike out as a tough guy? Anyone who used words and diplomacy? We’d say they were “emotionally intelligent”; that they has a set of “soft skills”… oddly patronizing, no?
Well, the truth is that the “cowboy” is a blowhard that can’t work well in the group, and “the group” is the better way to get things done. Talking to people, working with them and making them feel their opinion/input matters. That’s how you build relationships (business or otherwise) that will last.
Check out the video, it expertly touches on what we’ve hinted at, but it’s pretty much what you’d expect:
“…being self aware both emotionally and intelligently.” Knowing your strengths and weakness (and being confident or humble about them accordingly). In other words, “Know where you suck” and also “realize where you’re good too”. In the end “being self-aware like this, both emotionally and intellectually is a very good thing to be; it’s good to be in that state of mind…it’ll have a tremendous positive impact in your life.” Enjoy!
There are plenty of articles on how to build an e-commerce website. The problem is that they speak to web-nerds and not to the business people who want to build on online business.
This article speaks to those not so tech savvy entrepreneurs.
What we want to do:
The goal is to create an e-commerce website that builds a business using all the cheap and free tools available in the market today. One great thing about the nerd driven computer revolution, is the strong sense of community and desire to give opportunity to the masses.
Because of this freely available cheap and/or free technology, it is just so much easier today to start a business than it was just 15-20 years ago.
These are some of the questions this article will answer:
What are the components of an e-commerce site, and how do you best get those components into your web site?
I always wondered why on Windows, ‘alert’ boxes looked so ugly?
… they probably looked good on Macs though.
Since then, I’ve written software for business purposes in perhaps 8-9 languages. Over the years, I’ve come across many ways in which people classify languages:
Object Oriented vs. Procedural vs. Prototype
Scripting vs. Programming
Compiled vs. dynamic
… and many more.
Recently a more practical way of classifying languages has come to my attention – classifying languages by problem-domain or in other words, context.
I like this list, because it really conveys a sense of practical use for a language. I’ve hammered out the details below:
… best used to build operating systems, hardware drivers etc. Fast and gives you low level (close to the core) access to the computer. These languages are used when speed is critical.
These languages include:
… best used to build frameworks that support (make easy) application building. Not as fast (at run-time) as system level languages, but they provide a higher level of abstraction that makes writing software quicker and more productive.
These languages include:
… best used to build the actual business applications like web shopping carts/stores, connecting to databases and creating the screens for users to interact with the database.
These languages include:
These language all allow for extremely fast development.
Programmers are freed from the low-level details that you have to contend with when working with architectural and system level languages.
The fact that they’re all scripting languages (that don’t need to be compiled,) adds to the ease of use and speed of development.
It makes for an interesting way to look at languages … and our choice of what language(s) to use for a given project.
You can think of each type of database as a different way (conceptual and practical) to store and manage information.
Each type of database has its advantages and disadvantages. That said, by far, the most popular database type is the ‘relational database’. That’s why we concentrate on them here.
WHAT ARE ‘RELATIONAL’ DATABASES?
As I hinted at above, each database type has a different concept on how data/information should be stored and organized.
A relational database stores (and organizes) its data/information by creating relationships between different pieces of information (stored in virtual containers) that are â€¦ uh, related to each other.
To illustrate the point: if you had a brother, your mother would be the ‘key’ that forms the relationship between you and your brother.
With this analogy in mind, we can say that a relational database stores and tracks data by establishing relationships by using ‘keys’ (in this case, your mother) that are consistent between two pieces of information – you both have the same mother.
Popular relational databases include:
Â· MySQL (often used with PHP because it’s free)
Â· Microsoft SQL Server
WHAT ARE VIRTUAL CONTAINERS?
We all know that it’s much easier to store and find stuff/things (in your home) if you put the stuff into boxes and then label the boxes â€¦ much better than just leaving all your junk on the floor.
Though naturally a messy bunch, nerds have picked up on that fact, and realized that computer information should also be stored in boxes (virtual containers) that are labeled. In a relational database, we call these ‘boxes’: tables.
In a nutshell: the virtual containers in relational databases are called ‘tables’ and information is stored in tables.
MORE ABOUT TABLES
Database tables are virtual containers designed to hold and organize data. In many ways they look like spreadsheets where database tables have both rows and columns.
The difference between a spreadsheet (like Excel,) and a relational database table, is that the spreadsheet is designed (has built in capability) to manipulate data for the purposes of presentation – creating charts and reports etc.
Where on the flip side, a database table is designed (has built in tools/capability) to organize and maintain information and it can hold much, much more information than a spreadsheet.
So yes, you can store information in a spreadsheet, but it lacks many capabilities (and capacity) that you would find in a database.
We will learn more about the makeup of a table (purpose of the rows and columns) when we actually build one.
THE ‘RELATIONSHIPS’ IN RELATIONAL DATABASES
As I mentioned above, a relational database stores information in tables (the virtual containers) and then creates relationships/connections between the tables (and thus the data that is stored in the tables.)
This system/method of storing information (by creating relationships,) is efficient because of a few reasons; the most important being is that this style of storing information (in tables that are related to each other,) helps to prevent information from being duplicated needlessly.
A FUNDAMENTAL PRINCIPLE OF DATABASE DESIGN
One of the fundamental rules in database theory/design, is that information should not be duplicated:
â€¦ if you have multiple copies of the same information floating around, it takes up more disk space and can easily become a nightmare to organize.
By storing information in different tables, and linking that information to each other (that are related,) you avoid duplicating information. This will become clear when we actually build our first database â€¦ I know (that for now,) many of you are probably unclear about a few things â€¦ have faith, it will come!
The Internet is buzzing these days about the emergence of what people call ‘Web 2.0’. It’s important for web designers to understand what this is, because it affects all web design.
IN A NUTSHELL: Web 2.0 is a combination of factors/elements that leads to a much more social, interactive Web. Here is a short list of some of the key elements that make Web 2.0 possible:
AJAX allows for the rise of the truly ‘rich’ Web user experience: web pages that act like desktop programs … no need to refresh entire pages to see new content on the page.
Auto-syndication (sharing of content) via RSS/XML feeds – and software that allows you to easily create and access these XML feeds.
New ways to mass-communicate over the Web – podcast (mp3) and video.
BLOGS GOT THE WHOLE THING GOING
Blogging tools like WordPress and TextPattern got the whole thing going: most blogs automatically create RSS feeds.
Blogs also make it easier than ever before, for people to write content for the Web. No need for Web design software like FrontPage or Dreamweaver and no need to know HTML.
As such, there has been an explosion of content creation of the Web: people are writing like crazy! The three points to take away from this is:
Blogs make it simple to (essentially) create web pages.
Blogs automatically syndicate/share content via RSS.
Blogs make it easy for readers to interact with blogger’s (the authors,) via a built-in system that allows people to make comments … the social aspect enabled.
WEB 2.0 IS MORE THAN JUST BLOGGING
Another major characteristic of Web 2.0 is the remixing and combining of information from many different sources.
A Web 2.0 web site may grab many RSS feeds and massage them into a new filtered presentation. The advantage is that users can now access this information from one spot, instead of having to visit many different sites.
This (automated) sharing and mixing of content/information (between people and websites,) along with ‘rich’ Web user experience is Web 2.0.
More and more web designers are interested in taking the jump into learning how to build database driven websites.
These days, the language of choice is PHP (with some adventurous nerds jumping into Ruby,) because it is easy to use, easy to learn and is very popular.
Regardless of what technology/programming language (PHP, ASP, JSP, Cold Fusion) you use to build database driven websites, there are some (common) basic concepts that have to be understood before you can move forward.
