For the Microsoft technology also known as structured storage, see COM Structured Storage. A NoSQL (often interpreted as Not Only SQL[1][2]) database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases. Motivations for this approach include simplicity of design, horizontal scaling and finer control over availability. The data structure (e.g. key-value, graph, or document) differs from the RDBMS, and therefore some operations are faster in NoSQL and some in RDBMS.
There are differences though, and the particular suitability of a given NoSQL DB depends on the problem it must solve (e.g. does the solution use graph algorithms?). History[edit] There have been various approaches to classify NoSQL databases, each with different categories and subcategories. A more detailed classification is the following, by Stephen Yen:[9] Performance[edit] Examples[edit] Graph[edit] Oracle's NoSQL Database Overview. Oracle. Oracle Database 12c Release 1 (12.1) New Features. The following sections describe the new business intelligence and data warehousing features for Oracle Database 12c Release 1 (12.1). 1.2.1 Oracle Advanced Analytics The following sections describe new Oracle Advanced Analytics features. 1.2.1.1 Decision Tree Mining Text Data The Decision Tree algorithm now supports nested data and can be used for text mining.
Decision Tree is popular due to its transparency and prevalence, therefore, it is important to enable the algorithm to handle unstructured data. 1.2.1.2 Expectation Maximization (EM) Clustering and Density Estimation In Release 11g, Oracle Data Mining offered two clustering algorithms. In bringing analytics to applications, Oracle Data Mining provides different types of clustering capabilities currently being used by multiple applications. 1.2.1.3 Feature Extraction Using Singular Value Decomposition PCA can be viewed as a special scoring method under the SVD algorithm. 1.2.1.5 Native Double in Data Mining Functions ALTER TABLE ...
