DMDW Extra Lesson – NoSQL and MongoDB

On 06, Mai 2011 | 2 Kommentare | inDMDW lecture, NoSQL | vonJohannes Hoppe

This Friday I introduced you (== my students) to the wonderful new world of databases that are “not only SQL“ (NoSQL). Later on we played with the MongoDB shell and created, read, updated and deleted some documents.

For the MongoDB workshop we used some training data that you can find here. Please don’t forget to solve the exercises! You can contact me by blog-comment or mail, in case of further questions!

DMDW – Presentation of your ETL project

On 03, Mai 2011 | 2 Kommentare | inDMDW lecture | vonJohannes Hoppe

Hello Students,

as you know, every student
has to present his ETL project.

The task:

  1. Please Extract the content of the room-plan excel file
    (write me a mail if you don’t know the password)
  2. then Transform it to a new structure.
    (e.g. normalize the content, clean it, deal with typos, parse the dates…)
  3. and finally Load it to a new target.
    (In most cases this target will be a database system.)
  4. Present your solution to the other students, give me your materials. Don’t forget you name on the slides.

MongoDB – Training Data

My favourite next topic will be a short excursion to MongoDB. MongoDB (from „humongous“) is a scalable, high-performance, open source, document-oriented database. It has no SQL, JSON-style documents and is fast as hell! 👿

Please install MongoDB as described here: Quickstart Windows
And please download these files with sample data: dba-training-data.zip

These MongoDB Quick Reference Cards can be very helpfull:




Update:
Here are the slides for of NoSQL presentation and the MongoDB workshop!

RIA Presentations 2 – Time and Room

On 13, Apr 2011 | Keine Kommentare | inRIA lecture | vonJohannes Hoppe

This Friday, the 15th of April (2011-04-15), I will be happy to see your presentations.
Leets meet at 10 o’clock AM in the foyer; too search for a suitable room!

I like presentations that are well prepared and where all team members are presenting. There is no fixed format ore time box!
It’s up to you how you want to convince me that you’ve created an amazing project. But please keep in mind that too long or too boring presentations won’t be very convincing!  😉
