As any parent of a five year old can attest, time flies when you’re having fun. Where did all the time go? That’s kind of how we feel with N1QL, the SQL for JSON query language. Today, thousands of developers, customers and modern applications use N1QL in their applications to access, analyze, and manipulate data.
A N1QL Refresher
Couchbase created N1QL to make it easier for enterprise developers to make the transition to NoSQL. While moving to NoSQL already offers significant advantages, not all NoSQL databases are equal because their query languages are different. Most other NoSQL databases have limited SQL support — or none at all.
Having limited or no SQL support makes the migration of applications very expensive because the data access layer must be rewritten and developers must be retrained. (Remember: NoSQL means “not only SQL.”) N1QL gives application developers an expressive, powerful, and complete declarative language with industry standard ANSI joins for querying, transforming, and manipulating JSON data – just like SQL. Developers can visualize and optimize complex query plans for large datasets and deliver the best performance at any scale to meet the demands of millions of users.
By combining the power of SQL with the flexibility of JSON, N1QL allows developers to
write ad hoc queries without limitations. By slicing and dicing data with select, ANSI joins,
project, nest, unnest, group, sort, window functions, CTEs, user defined functions, and other data manipulation functions within a single query, developers can improve efficiency at the speed of business.
And over the years, companies have been choosing Couchbase over other NoSQL solutions because of the SQL-like query language in N1QL.
“When Couchbase introduced me to N1QL, we quickly realized that N1QL offers the flexibility to search with a language that looks 99 percent the same as SQL. So for all developers, it was an easy transition.”
