The NoSQL acronym suggests it's the SQL language that is the key difference between traditional relational and newer non-relational data stores. However, an equally significant divergence is in the NoSQL consistency and transaction models. Indeed, some have suggested that NoSQL databases would be better described as "NoACID" databases - since they avoid the "ACID" transactions of the relational world.

Karmasphere has introduced Karmasphere Analyst, productivity software for data professionals working with massive data sets. "Karmasphere is focused on providing software for developers and analysts to work with Big Data in Hadoop clusters. Over the past 12 months, we have been introducing products specifically focused on developers who are early adopters of Hadoop and are working on Big Data in Hadoop, but what we have heard time and time again from enterprise organizations is the need to unlock access to data in Hadoop clusters for enterprise analysts," Martin Hall, CEO of Karmasphere, tells 5 Minute Briefing.

Because any database that does not support the SQL language is, by definition, a "NoSQL" database, some very different databases coexist under the NoSQL banner. Massively scalable data stores like Cassandra, Voldemort, and HBase sacrifice structure to achieve scale-out performance. However, the document-oriented NoSQL databases have very different architectures and objectives.

There has been a lot of interest lately in NoSQL databases and, of course, many of us have strong backgrounds and experience in traditional relational "SQL" databases. For application developers this raises questions concerning the best way to go. One recurring truth that eventually surfaces with all new software technologies is that "one size does not fit all." In other words, you need to use the right tool for the job, as each has its own strengths and weaknesses. In fact, a danger of many new architectural approaches is one of "over-adoption" - using a given tool to address a wide array of situations when originally they were designed for the specific problem domain in which they excel.

The relational database - or RDBMS - is a triumph of computer science. It has provided the data management layer for almost all major applications for more than two decades, and when you consider that the entire IT industry was once described as "data processing," this is a considerable achievement. For the first time in several decades, however, the relational database stranglehold on database management is loosening. The demands of big data and cloud computing have combined to create challenges that the RDBMS may be unable to adequately address.

InterSystems Corporation has rolled out a new version of its Caché high-performance object database. The new release targets the growing demand by CIOs for economical high availability by introducing database mirroring, while also addressing Java developers' need for high-volume high-performance processing combined with persistent storage for event processing systems. Robert Nagle, InterSystems vice president for software development, recently chatted with DBTA about the release and the new features it offers. Commenting on the growing interest in NoSQL databases, Nagle observes that many of the beneficial characteristics people see in NoSQL are in fact true of Caché - a flexible data model and zero DBA cost. "But for us, what is unique is that it is not NoSQL, it is that it needs to be SQL - without the overhead of relational technology - because I think SQL is extremely important for almost every class of application that is deployed."

In Greek mythology, Cassandra was granted the gift of prophesy, but cursed with an inability to convince others of her predictions - a sort of unbelievable "oracle," if you like. Ironically, in the database world, the Cassandra system is fast becoming one of the most credible non-relational databases for production use - a believable alternative to Oracle and other relational databases.

NoSQL - probably the hottest term in database technology today - was unheard of only a year ago. And yet, today, there are literally dozens of database systems described as "NoSQL." How did all of this happen so quickly? Although the term "NoSQL" is barely a year old, in reality, most of the databases described as NoSQL have been around a lot longer than the term itself. Many databases described as NoSQL arose over the past few years as reactions to strains placed on traditional relational databases by two other significant trends affecting our industry: big data and cloud computing.

Quest Software, Inc. has introduced a beta program for Toad for Cloud Databases, a new data access and management tool for non-relational data stored in cloud databases, also known as NoSQL databases. Toad for Cloud Databases is intended to help users unlock data stored in the cloud by using the familiar SQL language or Toad's popular visual query and data access capabilities. Users can query and report on non-relational data, migrate data in both cloud and relational databases from one to the other, and create queries that combine the two.

VoltDB, LLC, has begun shipping the VoltDB OLTP database management system that is intended to offer faster transaction processing capabilities due to lower overhead. VoltDB, developed under the leadership of Postgres and Ingres co-founder, Mike Stonebraker, is a next-generation, open source DBMS that, according to the company, has been shown to process millions of transactions per second on inexpensive clusters of off-the-shelf servers. The VoltDB design is based on an in-memory, distributed database partitioning concept that is optimized to run on today's memory-rich servers with multi-core CPUs. Data is held in memory (instead of on disk) for maximum throughput, which eliminates buffer management. VoltDB distributes data - and a SQL engine to process it - to each CPU core in the server cluster. Each single-threaded partition operates autonomously, eliminating the need for locking and latching. Data is automatically replicated for intra-cluster high availability, which eliminates logging.

If you spend any time at all reading IT trade journals and websites, you've no doubt heard about the NoSQL movement. In a nutshell, NoSQL databases (also called post-relational databases) are a variety of loosely grouped means of storing data without requiring the SQL language. Of course, we've had non-relational databases far longer than we've had actual relational databases. Anyone who's used products like IBM's Lotus Notes can point to a popular non-relational database. However, part and parcel of the NoSQL movement is the idea that the data repositories can horizontally scale with ease, since they're used as the underpinnings of a website. For that reason, NoSQL is strongly associated with web applications, since websites have a history of starting small and going "viral," exhibiting explosive growth after word gets out.

The concept of database sharding has gained popularity over the past several years due to the enormous growth in transaction volume and size of business-application databases. Database sharding can be simply defined as a "shared-nothing" partitioning scheme for large databases across a number of servers, enabling new levels of database performance and scalability. If you think of broken glass, you can get the concept of sharding—breaking your database down into smaller chunks called "shards" and spreading them across a number of distributed servers.

Database sizes have grown exponentially, with more than half of all databases in use globally projected to exceed 10TB by 2010, according to The Data Warehouse Institute. But as the size of data warehouses has exploded and business requirements have forced companies to conduct more ad hoc queries on those warehouses, response times have slowed, requiring increasingly expensive database hardware investments.

The data explosion driving data warehouse equipment purchases in the last few years has just begun. Equipment proliferation already pressurizes data center energy requirements. Fortunately, a column-based analytics server can help companies with both kinds of green - the environment and money - by offering enormous energy and cost reductions while significantly boosting performance.
