Consistency Models in New Generation Databasesiammutex
Roger Bodamer talks about consistency models in NoSQL databases and how they compare to traditional RDBMS solutions, showing how different products deal with replication, multiple copies of information, consistency, failover, high availability.
Big Challenges in Data Modeling: NoSQL and Data ModelingDATAVERSITY
Big Data and NoSQL have led to big changes In the data environment, but are they all in the best interest of data? Are they technologies that "free us from the harsh limitations of relational databases?"
In this month's webinar, we will be answering questions like these, plus:
Have we managed to free organizations from having to do Data Modeling?
Is there a need for a Data Modeler on NoSQL projects?
If we build Data Models, which types will work?
If we build Data Models, how will they be used?
If we build Data Models, when will they be used?
Who will use Data Models?
Where does Data Quality happen?
Finally, we will wrap with 10 tips for data modelers in organizations incorporating NoSQL in their modern Data Architectures.
Coherence and consistency models in multiprocessor architectureUniversity of Pisa
Cache coherence and consistency model in multiprocessor architecture. These slide show the introduction of multiprocessor and cache multilevel and then describe the basic mechanism of coherence and consistency protocols. In particular the protocols describe are the following: snooping and directory protocols for the coherence part and sequential protocol for the consistency part. There are also example of (in)consistency and (in)coherence.
A stable data model provides numerous advantages in developing Big Data and NoSQL systems, especially when sharing data over the cloud. Adopting an immutable model eases much of the pain of achieving consistency, especially at great scale. There can be trade-offs however that you need to be aware of.
This webinar will present details and examples of immutable data models as applied to various NoSQL systems, including MongoDB, Cloudant, Riak and Cassandra. The emphasis will be on the impact to application designers and architects, as well as the technical trade-offs and advantages. The discussion will be well-grounded in real world examples from within and beyond the enterprise.
