Solve your toughest adoption and production challenges with an intuitive NoSQL query language, SQL++
High coding and migration cost
Most other JSON databases have limited SQL support, or none at all. To make matters worse, their languages are “imperative,” so the developer must specifically tell the database “how” to gather the data. This makes the migration of applications very expensive because you must rewrite the data access layer and retrain developers. It makes maintenance worse, too.
SQL and SQL++, on the other hand, is a “declarative” language. Simply ask SQL++ what to gather, and the database does all the work.
Application performance changes with volume, and when the database lacks a sophisticated query optimizer. The Couchbase Query Service includes cost-based optimization to ensure the best performance, and collection-level processing queries of indexing, sharding, and more. You will notice a speed difference as you scale.
When you use multiple databases, such as key-value for session caching and documents for product catalogs, you create unnecessary complexity that can lead to expensive trouble. Data can become inconsistent and overly duplicated. It’s a maintenance and cost nightmare to manage multiple databases for one application.
SQL++, SQL-like queries with the flexibility of JSON
Develop engaging applications with ease using a comprehensive and declarative JSON query language. Developers can rapidly adapt to changing business requirements using a schemaless JSON document store.Learn SQL++ in 10 minutes
Query without compromise, with capabilities you expect from SQL queries
SQL++ is a high-performance NoSQL query language with built-in optimizers and indexer enablers to support millions of concurrent interactions with sub-millisecond latencies. Couchbase’s multi-dimensional architecture leverages SQL++ across its query, index, search, and analytics services, partitioning to elastically scale data capacity and deliver accelerated query performance.N1QL: A practical guide
