Not all applications are equally suited to start your database migration journey.ДЇirst, you want to identify those current applications that no longer meet the evolving needs of the business. With all these capabilities Couchbase now makes it possible for enterprises to modernize their slow-performing, rigid applications that are relying on aging relational databases. This makes it possible to modify the database documents inside a transaction and then commit or rollback all of the changes in the transaction depending on the application logic, making it fully ACID compliant. In addition, distributed SQL transactions have been added to the N1QL query language.

See the table below for a full comparison. Using this hierarchy, you can map a relational database to a bucket, in which a JSON document represents a row, the collection represents a table, and the scope being the grouping of related collections. Multiple JSON documents can be brought together into a collection, which in turn can be grouped together into a scope, which is stored into a bucket.

With the introduction of scopes and collections in Couchbase 7.0 itвЂ™s now possible to organize data in such a way it easily maps to rows and columns of tables from an RDBMS. However, pulling multiple JSON documents into buckets to set up a data model doesnвЂ™t provide the granular hierarchy needed to easily map relational tables into a NoSQL database. The document database architecture вЂ“ which stores information in JSON documents вЂ“ provides the schema flexibility that is lacking in relational databases. Legacy Modernization Made Simple with Couchbase The introduction of Couchbase 7.0 put an end to that assumption by adding ACID-compliant SQL transaction capabilities and a Dynamic Data Containment model that adds multiple logical organization layers called scopes and collections. ACID compliance for transaction-oriented workloads has been uniquely associated with relational databases and was considered incompatible with a NoSQL distributed architecture. In addition, Couchbase provides SQL query capabilities on JSON data with the N1QL query language, so that database administrators, architects and developers can re-use their existing SQL expertise in a NoSQL environment.Д«ut thatвЂ™s not enough to be a viable alternative to legacy databases. Couchbase is unique in combining all the advantages of a NoSQL database architecture paired with enterprise class capabilities that ensures reliability and performance companies expect from a data technology platform. NoSQL databases deliver the flexibility and scalability modern applications need while flexing with a fluid data structure. Amadeus improved query performance by over 1000% by switching to Couchbase from Oracle.Sky replaced the limitations of their legacy Oracle RDBMS with the flexibility of NoSQL to improve customer experience during peak traffic.Marriott deployed NoSQL to modernize its hotel reservation system that supports $38 billion in annual bookings.NoSQL databases have successfully been used to address the major shortcomings of relational databases, and NoSQL has achieved a track record with production deployments in the most demanding business environments. Such a dynamic environment requires companies to adapt fast without the constraints of an aged IT infrastructure. They not only want to consume information, but also want to share their insights and experiences for the benefit of others. Users and consumers have gotten used to instantaneous access to the latest information when and where they need it. The corporate world is littered with companies who failed to quickly adapt to a changing environment. In this article, weвЂ™ll cover what makes Couchbase a better alternative to rigid and costly relational databases, and why enterprises use the erwin Data Modeler to migrate their applications to Couchbase. Digital transformation driven by mobile technology, ecommerce, IoT and personalized interactions requires a new approach to how applications interact with data stores. However, the past success of relational databases (RDBMS) is no measure for whatвЂ™s needed in todayвЂ™s economy. The relational database has been foundational to the information economy just like the steam engine enabled the industrial revolution.
