IBM DB2 vs MarkLogic: What are the differences?
Developers describe IBM DB2 as "A family of database server products developed by IBM". DB2 for Linux, UNIX, and Windows is optimized to deliver industry-leading performance across multiple workloads, while lowering administration, storage, development, and server costs. On the other hand, MarkLogic is detailed as "Schema-agnostic Enterprise NoSQL database technology, coupled w/ powerful search & flexible application services". MarkLogic is the only Enterprise NoSQL database, bringing all the features you need into one unified system: a document-centric, schema-agnostic, structure-aware, clustered, transactional, secure, database server with built-in search and a full suite of application services.
IBM DB2 and MarkLogic can be categorized as "Databases" tools.
"Rock solid and very scalable" is the primary reason why developers consider IBM DB2 over the competitors, whereas "RDF Triples" was stated as the key factor in picking MarkLogic.
