There are several use cases where data extracted from live data streams such as Twitter may need to be persisted into external databases. In this example, you will learn how to filter incoming live Twitter data and write relevant subsets of Twitter data into IBM database DB2. Sample program will work against all flavors of IBM databases i.e. DB2 for z/OS, DB2 distributed, dashDB and SQLDB.…
We are seeing a trend of DB2 data being accessed by modern distributed applications written in new APIs and frameworks. JavaScript has become extremely popular for Web application development. JavaScript adoption was revolutionized by Node.js which makes it possible to run JavaScript on the server-side. There is an increasing interest amongst developers to write analytics applications in Node.js that need to…
There are several use cases where data in Spark needs to be persisted in a backend database. Enterprise wide analytics may require load of data into Spark from different data sources, apply transformations, perform in-memory analytics and write the transformed data back to a enterprise RDMS such as DB2.
In this blog, simple techniques are shown using latest Spark…
Spark SQL gives powerful API to work with data across different data sources using Python, Scala and Java. In this post, we will demonstrate how easily DB2 data (both z/OS and LUW) can be loaded into Spark and joined with JSON data using DataFrames.
We will use a standalone Java program in this example. For setup of Eclipse to work with Spark, please refer to…

My colleague Param (param.bng@in.ibm.com) and I (pallavipr@in.ibm.com) are exploring various aspects of Spark integration with DB2 and DB2 Connect drivers. We have decided to write a series of blogs capturing our experimentation for the benefit of others as we did not find any article that focuses on different aspects of DB2 access via Spark.…
Application paradigm has evolved rapidly – new programming and scripting languages geared towards Web and Mobile spring up regularly. DB2 has embraced new developments in the application space and continues to be the database…
Java has evolved into a viable alternative to COBOL for many DB2 z/OS customers. There is an emerging trend for customers to write new business logic in Java, and in some cases replace COBOL business logic with Java. This offers several advantages -
Standard Java APIs (such as JDBC) allows customers to enable applications for diverse mediums such as Web and Cloud.
Developers can…
DB2 for z/OS is the preferred Systems of Record for mission critical enterprise data. With the advent of Cloud paradigm, enterprise customers are looking for ways…
