When your company needs answers from big data in real time, the data is streamed so it can be filtered or sampled, aggregated and correlated—all to bring about a real-time answer to an important business question. “Streaming data is table stakes for the most interesting future use cases,” said Mark Brewer, CEO at Lightbend. “And that’s giving rise to the number of programming languages, frameworks and tools for building and running streaming data-centric applications.” However, streaming data—especially unstructured big data like what comes from Internet of Things (IoT) devices—can require knowledge of sophisticated processing architectures and investments in tools as well.

1. Be aware of distractions

Distraction was a key element in the first presidential debate and likely served as a means of confusion for listeners. It blanked the entire debate and made it difficult for the audience and the two candidates. The result was a lost opportunity to share their intended messages and plans for the future with stakeholders.

Distraction can be a strategy of some to reduce the effectiveness of others. Project leaders should

For decades developers would build applications using the same database tools. They might opt for Oracle over IBM’s DB2, or for an open source database like MySQL or PostgreSQL, but they were nearly always all using a relational database, speaking SQL. 

My, how times have changed.

Must-read developer content

Today developers have a smorgasbord of options from which to choose, whether document or key-value or columnar or relational or multi-model. But over the past two years, no database category has seen more growth than time series databases, something evident a year ago but now glaring in its obviousness. When I asked Timescale CEO Ajay Kulkarni why this once niche, now prevalent approach has gained in popularity, he explained it as a matter of data fidelity: “Time

Though life has resumed a measure of normalcy for many in the wake of COVID-19, earlier in 2020 life came to an abrupt stop. No more travel. Tightly restrained social interaction. Widespread adoption of work-from-home policies. Everything changed.

Must-read developer content

Everything, that is, except open source software development. 

Despite the difficulties of WFH arrangements (increased childcare duties, social isolation, unfamiliar work arrangements, etc.), open source software developers didn’t miss a beat. In fact, as evidenced by data from the Apache Software Foundation (ASF), code commits increased in the wake of the global pandemic. As ASF president David Nalley related in an interview during Apacheon 2020, “The asynchronous, distributed communications and decision-making of open

The digitization of the modern business enterprise has created a seemingly never-ending stream of raw data. Gleaning actionable nuggets of information from terabytes upon terabytes of data requires systems that can store, retrieve, and process data quickly and efficiently. One of the most common of these systems is called a data warehouse.

Data warehouses are central repositories of integrated data obtained from one or more disparate sources. These systems store current and historical data in one single place, which can then be retrieved for the development of analytical reports and other actionable information for employees throughout an enterprise. A well-designed and comprehensive data warehouse can unleash the power of institutional collected data.
