In The fundamentals of data warehouse architecture, we covered the standard layers and shared components of a well-formed data warehouse architecture. In this second part, we’ll cover the core components of the multi-tiered architectures for your data warehouse.

It's been 12 days since 61 speakers took to the stage for our 2023 Mobile DevOps Summit. There were a total of 43 sessions on day one and 13 workshops on day 2. We had a lot of content! Here are a few memorable quotes from the 2-day Summit!

Any organization that uses diverse applications and web services need a comprehensive way to manage its application programming interfaces (APIs). As two of the biggest names in technology, Oracle’s and IBM’s tools tend to stand out to people reviewing their options. Can Oracle API Manager or IBM API Management meet your needs while staying within your budget? The following review compares and contrasts the API solutions to help you make an informed decision.

In today’s data-driven world, there is a huge amount of data flowing into the business. Engineers spend a large part of their time in building pipelines—to collect the data from different sources, process it, and transform it to useful datasets that can be sent to business intelligence applications or machine learning models. Tools like Airflow are used to orchestrate complex data pipelines by programmatically authoring, scheduling, and monitoring the workflow pipelines.

Most websites are built with high-level languages like Ruby. Developers can always optimize their code for improved performance. Yet, even with top-notch optimization practices, what if your website still lags? How could WASM help improve the performance (time and speed) of your Ruby apps? Web Assembly is a technology that allows developers to compile code written in languages other than Javascript and run it on the web browser.

In the Ruby community, there's near-unanimous agreement on the importance of testing. Tests act as a safeguard, ensuring that the digital experiences we craft remain consistent, reliable, and of high quality. Many in the Ruby community claim that no code change is complete without tests. They are an integral part of the development workflow. Regular testing ensures that new features, refactors, or bug fixes do not introduce unforeseen issues or regressions.

Multi-tenancy is almost a prerequisite to provide a secure environment for each of your customers when using business intelligence (BI) tools embedded in external services. Although it is possible to control the access rights by granting individual access to user accounts without separating tenants, it is obvious that the management will become more complicated as the number of customers grows. In a previous blog, we covered what multi-tenancy means in the context of embedded analytics.

Cloudera recently released a fully featured Open Data Lakehouse, powered by Apache Iceberg in the private cloud, in addition to what’s already been available for the Open Data Lakehouse in the public cloud since last year.

Customers can deploy Open Data Lakehouse wherever the data resides—any public cloud, private cloud, or hybrid cloud, and port workloads seamlessly across deployments.

The java.io.IOException is a checked exception in Java that indicates a problem while performing Input/Output (I/O) operations. This usually happens when a failure occurs while performing read, write or search operations in files or directories. Since IOException is a checked exception, it must be explicitly handled in methods that can throw this exception - either by using a try-catch block or by throwing it using the throws clause.
