Greetings to all of my friends who work in the area of computerized decision support. This blog is a way for me to share stories from my encounters related to decision support, to comment on industry events, and to comment on other blogger's comments, especially those of my friends on the Business Intelligence Network. I'll try to state my opinions clearly and provide an old professor's perspective on how computers and information technology are changing the world. Decision making has always been my focus, and it will be in this blog as well. Your comments, feedback and questions are welcomed.

Amazon Web Services (AWS) hosts many popular Web applications including: Instagram, Vine, IFTTT, Netflix, Heroku and Airbnb. AWS delivers a set of services that together form a "reliable, scalable, and inexpensive computing platform 'in the cloud'". On Sunday, August 25, 2013, AWS Server issues crashed a number of applications including Instagram (instagram.com), a photo and video sharing service. Chris Velazco at http://techcrunch.com/ reported AWS was having problems at the north Virginia data center. AWS was "reporting issues with its EC2, relational database, and load-balancing services". Can companies rely on Amazon Web Services for relational database transaction processing and online analytical processing?

This past week (Aug. 20-22, 2013), I attended a great conference in San Jose, CA on NoSQL technologies.  The URL is http://nosql2013.dataversity.net/ .

Tony Shaw, President of Dataversity, and Dan McCreary, Principal Kelly-McCreary & Associates, created a stimulating agenda.  Overall the presenters were knowledgeable, the vendors were excited and helpful and the facilities, support and food were excellent.

I prefer the term Post-relational databases rather than NoSQL, but ... 

The talks and sessions discussed four product categories.  McCreary identified them as 1) Key-Value databases, 2) Document databases, 3) Graph databases, and 4) Column-Family databases.

Database technology must fit the purpose of the database and the data.  The relational data model and relational database remain the best for transaction databases.  New data models and new DB technologies are useful for decision support and other data storage, analysis and retrieval needs.

Change is definitely occurring in our global society. Some changes are minor and seemingly insignificant. Other changes linked to mobile computing and "smart" software seem more disruptive. The forces creating the changes are difficult to discretely identify. We live in a multi-causal world of pressures that are tugging, pushing and interacting. One cannot say definitively that the Internet or social networks or even computers are having or have had a profound impact on how we live. Perhaps we live in an emerging hyperconnected, digital or information age. Perhaps the change process has just begun. We can certainly interact easily with people from most countries often in real-time. Most data is now digital and we are creating and capturing enormous amounts of data. Where are we headed?

I will be attending the NoSQLNow! 2013 conference in San Jose August 20-22. On the first day,Tuesday, I'm planning to attend two tutorials: 1) Introduction to the Hadoop Ecosystem with Vladimir Bacvanski, SciSpike and 2) NoSQL Database Patterns: Architecture and Design Patterns of Non-Relational Databases with Srini Penchikala, InfoQ. The entire tutorial offering seems useful.

The keynote presentation on Wednesday morning by Andrew Mendelsohn, Oracle, is titled "Oracle NoSQL Database".  Prior to lunch, Adrian Cockcroft, Netflix, will present on Managing Scale and Complexity.  The entire schedule is at http://nosql2013.dataversity.net/agenda.cfm?confid=74&scheduleDay=PRINT .

I'll blog about what I learn and do at NoSQLNow! http://nosql2013.dataversity.net/
