There are two main reasons to consider running your NoSQL work on a DB2 for z/OS server: The statements above are in the form that would be used in that command shell. Examples include:ĭB2 provides a command line processor for performing ad hoc queries and administration commands. It has been noted that the capabilities and syntax have many similarities with SQL itself. In June 2013, IBM and MongoDB jointly announced an informal partnership to promote and standardize the MongoDB dialect as the lingua franca of NoSQL document databases, and that is the dialect that is adopted by DB2. The query and data manipulation syntax introduced by MongoDB was already very popular for its simplicity and natural integration into dynamic programming languages.

The other applications are limited to the syntax that the client driver understands, so DB2 extensions are not enabled. This difference between Java applications and other languages means that Java programs will have access to some DB2 capabilities that these other applications cannot. This is a socket-based, daemon program written in Java that understands the network protocol spoken between a client application and a MongoDB server.

For other programming languages, you can use a MongoDB-style program, along with the proper language driver that you can download from a MongoDB community site, and then modify the connection properties to point at the DB2 JSON wire listener program. Much of the DB2 JSON API is conceptually compatible with the workings of the MongoDB JSON database.

The core of the JSON API is a set of Java classes, so native Java applications can code directly to those classes and methods.įor applications written in other programming languages, a different approach is used. Native Java applications are handled a bit differently than applications written in other languages. Applications using the same JSON API code can connect to DB2 on either platform (see figure below). This capability leverages client and application side code provided a few months earlier with the DB2 for Linux, UNIX and Windows (LUW) 10.5.0.1 delivery. DB2 11 support followed shortly after, becoming available in June. In February, DB2 10 for z/OS rolled out support for a new API for managing JSON documents. In fact, MongoDB’s JSON document store database has become nearly synonymous with the NoSQL database movement. Part of this development agility is due to the schema-less or flexible-schema nature of the storage formats.Īn example of this flexible format can be seen in JSON, which has quickly become not only the preferred messaging format for mobile and web applications but also a popular format for NoSQL document databases.

The easy install and rapid time required to get an application working have obvious appeal to developers. This NoSQL movement has in large part been driven by line of business application development efforts. This time, the technology brings not only a new storage format, but also new languages for communicating from application to database. Yet with each of these new technologies, the relational database has incorporated them and ultimately exceeded the value of the standalone offering by combining the new features with familiar relational capabilities.įast forward a bit: In the past three to four years, the term NoSQL has gone from a curiosity to a must-have component for many database development organizations. Object Databases, XML, remote procedure calls and in-memory databases are good examples. More than once in the past 20 years, it has seemed that DB2 and other relational databases would lose relevance as each new revolution in data storage format or programming approach arrived.
