This data model is very similar to the structure of a table and uses java.util.Map "hash" in which there is a single key and an indicator of a given or a value of a particular item. The key-value model is the simplest and easiest to implement.
This is similar to storing the key type / value. Except that databases of documents permitting a document as a whole and not divide a document into its key / value constituents. This allows the development of a diverse set of documents into a single collection. The indexing virginia metalcrafters of documents is based not only on its primary identifier, but also on their properties. In the scheme virginia metalcrafters below, one can observe how the data is stored in this model.
The graph-oriented model has three basic components: nodes (are the vertices of the graph), relationships (are the edges) and the properties (or attributes) of nodes and relationships. In this case, the database can be seen as a labeled, directed multigraph virginia metalcrafters where each pair of nodes can be connected by more than one edge.
This model was developed to store and process large amounts of data distributed across many machines. There are keys, but they point to multiple columns. The columns are arranged virginia metalcrafters by family column. The storage virginia metalcrafters column allows virginia metalcrafters data to be stored efficiently. Avoid consuming space to store null values by simply not storing a column when a value does not exist for that column. virginia metalcrafters
Congratulations Eliane's initiative blog, some time looking for references of Apache Cassandra. I found this blog via NoSQL Br and I've read about four matters ... all very clear and objective! Delete Reply
