Piggydb Use Case: Relationships(Links) for Quick Reference

Piggydb user David Shrader kindly shared his experience of using Piggydb for his study. He utilizes piggydb’s relationships(links) to allow him to quickly access basic information to learn via Fragment Quick View.


I was in class training to earn my Oracle OCA certification, and I was having a lot of trouble studying for the 1z0-151. I had my notes in a notebook, and I found that if I read over the “key facts” I was reading a lot more than necessary about certain elements, and not enough about others. I passed my test, but only by 4 points.

Fast forward to studying for my 1z0-152, and I knew that I had to do something different to learn the material. In addition to staying up many late nights studying, I also began using piggydb to take notes and link pieces of knowledge together. The most beneficial thing for me was being able to create links (example syntax [fragment:99 BASIC INFO]) to knowledge fragments, allowing me to hover over the links to glance at information I already knew, and if I realized I didn’t understand something well enough I was able to open the link and read over the entire concept in depth. This may not sound very helpful, but for my learning style it was perfect. I was able to include charts and tables in the fragments for each key term, and I wasn’t forced to have them in the same (illogical) order as the books. I displayed storage charts from the largest to smallest element, etc. Then I was able to link the knowledge fragments together when they were related, which also helped cement the information in my mind.

So what was the final outcome you might ask? I scored a 93 on the 1z0-152. My instructor was shocked. Just for the sake of comparison, I scored a 64 on the first exam. That’s a 29% improvement thanks to piggydb, lol.


Thanks, David!

Let’s Play: Piggydb Knowledge Creation #4 – “Metaphors We Live By” by George Lakoff, Mark Johnson

It’s been a while since the last installment. It is partially because this time I took up a book with structure-rich content: an academic essay.

Metaphors We Live By” is the book I selected this time. It is one of the cornerstone books of cognitive linguistics, dealing with conceptual metaphor, which, according to this book, plays a central role in defining our everyday realities.

I’m not a specialist in this field at all and haven’t studied it before. So it was a time-consuming task for me to digest the content and somehow restructure it on Piggydb.

As a result, it produced far more knowledge fragments and a complex structure than before. And it’s also the most abstract topic in this series because it deals with the cause of our intelligence.

As the number of the fragments grew, I felt it was important to try to make a title for each fragment. It’s good for both to grasp your knowledge-base later and understand what you have quoted from a book. A shorter title would be better, and if a title becomes a noun, you should consider to put the fragment in a higher place. A key to comprehend a complex idea is to rearrange the content in a concept(noun)-oriented way. If you look into the example in the above links, you’ll see most of the top level fragments have a noun as their title.

In the course of dealing with such a complex content, I felt Piggydb should become more expressive. The book contains many new ideas found after it was first published and updates of the old ideas explained in the original content. To express these subtle relationships, I think it needs to improve in terms of fragment’s relationships.

Piggydb V6.16 – Fragment Quick View

Piggydb has provided you with ways to easily navigate through a knowledge-fragment network, for example, the tree and list views. This release adds another alternative to these navigation features: Fragment Quick View.

It allows you to move through a network, fragment by fragment, more lightly.

Mouse hovering over a link to a fragment for a second brings up a pop-up view for the fragment:


In the pop-up view, you can move to another fragment via links (the parents, children or links in the fragment content):

Piggydb V6.15 Supporters Edition: Embed Ustream Videos

Finally, though it is a small one, I’ve added a new feature, which is exclusive to the Supporters Edition.

You can now embed Ustream videos into your knowledge fragments just by putting video URL like: http://www.ustream.tv/recorded/38909163


With this as a starting point, I’m going to add further Wiki-formatting extensions in coming versions of Supporters Edition.

Piggydb V6.15 – Tag Icons for Each Type of Tags

This release changes the tag icons to have different colors according to the types of tags:

System Tag (starting with ‘#’ and used for management purposes):


Plain Tag:


Tag Fragment:


This update would be important more than you think, because tag-fragments are the most important parts of Piggydb database and the new version allows you to easily recognize your tag-fragments from the others.

Piggydb V6.14 – Expand Sub-fragments After Reading Content

Have you ever encountered a situation that you had read a long fragment and subsequently wanted to read its sub-fragments, but it was quite frustrating to scroll back to the fragment header to click on the tree toggle button?

This version fixes this problem by adding a button at the bottom of the content:


Clicking on this button expands the sub-fragments like the tree toggle button does:



This version also adds support for non-ascii file names when you upload files as file fragments.
