Interview on JQuery

2010-02-07, Chariot Solutions

Two weeks ago, Chariot Solutions had a day long event for our consulting team. With the original name of Chariot Day, our team has a series of talks on all different subjects. Some of the talks are on topics which may never see the light of day in the enterprise, some are about more accepted tools. Some of those talks and presentations will be the beginnings for seminars we will host for the public. I thought I would take advantage of having so many topics to choose from for interviews. I will be posting them as I have the time to edit them. This first one, with Lyle Anderson, is on JQuery. Lyle gave a two-part presentation which was well attended by our architects. When I see that much interest from the team, I know this is a technology worth watching. We are still waiting to confirm, but it looks like we will be having a talk at ETE 2010 (www.phillyemergingtech.com) by Yehuda Katz. [...Read More...]

Why You Need NoSql in Your Toolbox

2010-01-30, Chariot Solutions

Even if you work for Oracle, you still need NoSql databases in your toolbox. One size does not fit all for programming languages, operating systems, IDEs, shoes, bailouts, or anything else. But for a long time now, many developers have been told that relational databases are really the only choice for persistence. If you need to store some data -- any data -- shove it in a relational database. It is the safe choice, and gives us developers one less thing to worry about, right? Well actually, wrong. RDBMS' are great solutions to many problems, but there are better alternatives for others. Quick overview of NoSql A simple definition of a NoSql database is a schema-less database that does not support joins or ACID transactions. In a broad simplification, there are 2 types of NoSql databases: Key/value -- A "giant hash table in the sky" that stores key value pairs. Pros : * very fast * very scalable * simple model * many are distributed Cons : many data structures (objects) can't be easily modeled as key value pairs Schema-less -- Databases somewhere in-between key/value and relational including: column-based (different rows in same table can have different columns), document-based, and [...Read More...]
