MarkLogic 7 Unveiled
MarkLogic Corporation today announced the latest version of its Enterprise NoSQL database platform, MarkLogic 7. To help organizations gain better operational agility and optimize storage costs, MarkLogic 7 supports cloud computing, can run natively on the Hadoop Distributed File System (HDFS), and has new features that enable database elasticity and searchable tiered storage. Additionally, to help users understand and gain more meaning from their data, MarkLogic 7 introduces MarkLogic Semantics. MarkLogic Semantics combines the power of documents, data and RDF triples (also known as Linked Data) to enable analysts to understand, discover and make better informed decisions, and to power the delivery of the most comprehensive, contextually relevant information to users.
MarkLogic automates the process of segregating data into different storage tiers allowing for the cost of storage to reflect the value, relevancy and timeliness of the data, whether it is for real-time operational applications, archiving, batch applications, or batch analytics. The data remains readily available with sub-second query performance, so it can still adhere to governance, compliance and security policies over the entire lifetime of the data, even while leveraging cost-effective public or private cloud platforms.
In addition to local disk, SAN, NAS and other traditional file systems, MarkLogic can run directly on top of the Hadoop Distributed File System (HDFS) for either operational or archived data. This eliminates the need for costly and time-intensive extract, transform and load (ETL) process each time data needs to be used, and allows the cost of indexing to be amortized over the life of the data.
A combination of advanced performance monitoring, programmatic control of cluster size, sophisticated data rebalancing and granular control of resources bring agility and elasticity to the data layer whether it is on-premise or in the cloud. MarkLogic can also leverage Amazon S3 either as a native storage tier or for cloud backup from an on-premise deployment, enabling hybrid on-premise/cloud architectures. All of this is possible because MarkLogic supports ACID transactions, which are table-stakes for any database that will be used for mission-critical applications.
The new Semantics option stores the RDF triples, documents and data in the same proven Enterprise NoSQL database, maintaining context and making the facts available for decision-making. In addition, MarkLogic Semantics, with a specialized triple index, enables industry-standard SPARQL queries combined with queries against documents and data, so that all relevant information can be delivered in applications and analytic reports.
Although still early in the adoption cycle, semantic technologies enable organizations to gain additional insights by allowing users to leverage facts from many sources, including Linked Data.
