<p>When you're trying to find a solution to your problem, think on the way the
|
||
|
|
data will flow through your code.</p>
|
||
|
|
<span id="continue-reading"></span>
|
||
|
|
<p>Instead of focusing on design patterns, a better way is to think the way the
|
||
|
|
data will flow -- and be transformed -- on your code.</p>
|
||
|
|
<p>For example, the user will input a number. You'll get this number and find the
|
||
|
|
respective record on the database. This is a transformation -- no, it's not
|
||
|
|
"I'll get the number and receive a complete different thing based upon it",
|
||
|
|
you're actually transforming the number into a record, using the database as a
|
||
|
|
transformation.</p>
|
||
|
|
<p>(Yes, I know, it's not that clear at the first glance, but you have to think
|
||
|
|
that they are the same data with different representations.)</p>
|
||
|
|
<p>Most of the time I did that, I managed to come with more clear design for my
|
||
|
|
applications. I didn't even think about how many functions/classes it would be
|
||
|
|
needed to do these kind of transformations, that was something I came up
|
||
|
|
<em>after</em> I could see the data flow.</p>
|
||
|
|
<p>In a way, this way of thinking gets things more clear 'cause you have a list
|
||
|
|
of steps of transformations you need to do, so you can write them one after
|
||
|
|
another, which prevents a lot of bad code in the future.</p>
