Feed: SAS Blogs. Author: Leonid Batkhan. In this post, we tackle the problem of calculating the length of overlap of two date/time intervals. For example, we might have two events — each lasting several days — and need to calculate the number of shared days between both events. In other words, we need to calculate the length of the events’ overlap. Such tasks are typical in clinical trials programming, health (and non-health) insurance claim processing, project management, planning and scheduling, etc. The length of the overlap can be measured not only in days, but also in any other units of ...

Feed: Planet MySQL; Author: Frederic Descamps; As you know, MySQL 8.0 can be used as JSON Document Store to store your documents without being linked to any schema. You can also use CRUD operations to deal with these documents using the MySQL X DevAPI. Of course in documents, it’s possible to also store temporal attributes like date, time, datetime, … Let’s see how we can deal with such attributes. This is an example of a collection of documents with a datetime attribute createdOn: As those attributes don’t have a real type, can we use the createdOn attribute as if it ... Read More

Feed: AWS Architecture Blog. Organizations are using Amazon Simple Storage Service (S3) for building their data lakes, websites, mobile applications, and enterprise applications. As the number of objects within your S3 bucket increases, you may want to move older objects into lower-cost tiers of Amazon S3. In some cases you may want to delete the objects altogether to further reduce S3 storage costs. A common practice is to use S3 Lifecycle rules to achieve this. These rules can be applied to objects based on their creation date. In certain situations, you may want to keep objects available that are still ... Read More

Feed: Planet MySQL; Author: Joshua Otwell; I recently wrote a blog post on porting over Oracle SQL to comparable MySQL queries with the purpose of counting specific weekdays occurrences in a given month. That post was inspired by this YouTube video (which I highly recommend). I published a post over on Medium about some of the Oracle Date functions available for these types of queries as I learn more Oracle SQL and wanted to share it with readers here who may be interested… Digital calendar on a tablet on a table.

Feed: Planet PostgreSQL. In my day to day, I'm surrounded by great database engineers. They talk about things like HA and raft protocol and the right and wrong approach for configuring synchronous vs. asynchronous replication. There is a lot of value in all that deep technical knowledge, but for when interacting with customers, I like to boil it down a bit. What I've seen is that for many folks the basics of key database principles can get lost in the details. What follows is a summary of  conversations I've had with customers on how to think about key tenants of ... Read More

Feed: AWS Big Data Blog. Organizations across the globe are striving to improve the scalability and cost efficiency of the data warehouse. Offloading data and data processing from a data warehouse to a data lake empowers companies to introduce new use cases like ad hoc data analysis and AI and machine learning (ML), reusing the same data stored on Amazon Simple Storage Service (Amazon S3). This approach avoids data silos and allows you to process the data at very large scale while keeping the data access cost-effective. Starting off with this new approach can bring with it several challenges: Choosing ... Read More
