With so many SQL and NoSQL databases out there – MongoDB, PostgreSQL, MySQL, etc. – you may wonder why we chose to implement CouchDB instead of the others. We have two very good answers to that question: HTTP and sync. HTTP: the little protocol that could When working with databases...
PostgreSQL allows users to define objects, and use encapsulation and inheritance. It also permits users to define their own data types and has added a few NoSQL features, including built-in JSON support. This extends its capabilities and makes it better for processing complex queries and storing...
You can also send Prolog queries to the server using e.g. Java or HTTP. More on AllegroGraph Federation We have already talked about federation in the context of querying very large databases using the FedShard™ facility. In this section, we give more details about federation in general....
To meet these needs, NoSQL approaches and distributed file systems for the management of Big Data were born, the current reference technologies are Mongo DB, Hadoop File System and Cassandra DB. 1.1.1.5. Data abstraction In this level methodologies and technologies for assigning a meaning to the...
SQL Server also supports PolyBase, which is a data virtualization solution in SQL Server. It allows you to create external tables in your database that point to external data sources like Hadoop clusters, Oracle, Teradata, NoSQL databases, and SAP HANA. You'll be able to query all your dat...
We have already talked about federation in the context of querying very large databases using the FedShard™ facility. In this section, we give more details about federation in general. AllegroGraph uses that same programming API to connect to local triple stores (either on-disk or in-memory...
