Feed: Planet NoSQL. Author: Keshav Murthy. As part of data remodeling, while moving from the relational model to the JSON model, you’ll have to consider the data type mapping. In Oracle, you’ll have to create and declare the types of each column explicitly before you load the data or write queries. In Couchbase, you simply conform to JSON syntax and the data type interpretation is automatic and implicit. Here’s the overview of mappings, conversion, and arithmetic on these data types.[Here’s the home page for the series: http://blog.planetnosql.com/2022/01/introduction-to-couchbase-for-oracle.html]ReModeling: From relational to Document model OracleCouchbaseModelRelational, Object-relationalJSON model with N1QL (SQL for JSON)Data TypesLong list of ...

Feed: SAS Blogs. Author: David Shannon. One of the most discussed tech topics in the last 12 months has been hyperautomation. It has led to so many conversations that I now get episodes of déjà vu in the middle of meetings. I think this is a good thing, as organisations recognise the need for flexible innovation, rapid product development and putting customers in control of how they consume to create a truly valuable customer experience. So it is time to highlight some critical thinking on hyperautomation. In a series of blogs and supporting activities throughout 2022, I am going to discuss why hyperautomation has become an essential focus and could be key for survival ... Read More

Feed: Planet NoSQL. Author: Keshav Murthy. Oracle DBAs work with physical clusters, machines, instances, storage systems, disks, etc. All of Oracles users, developers and their applications work with logical entities: databases, tables, rows, columns, partitions, users, data types.  There are a lot of similarities and some differences.  Let’s compare and contrast how this is done on Couchbase.Here’s the home page for the series: http://blog.planetnosql.com/2022/01/introduction-to-couchbase-for-oracle.htmlORACLE OrganizationFull list of Oracle schema objects are listed here.

Feed: Planet MySQL; Author: Frederic Descamps; Today we are already at the post number ten of the series of articles related to extending MySQL with the Component Infrastructure, the list above will be updated as new articles are published: Today we will keep improving our component by adding some status variables. What I have in mind is to add the following status variables: clamav_signatures (integer): the amount of signatures loadedclamav_engine_version (varchar): the ClamAV Engine Versionvirus_found (integer): counter of detected viruses Once again, we will use a MySQL Component Service to handle our status variables: the Status Variable Registration service. In ... Read More

Feed: Planet NoSQL. Author: Keshav Murthy. INTRODUCTIONYou know Oracle, but need to a good overview of Couchbase, a modern NoSQL database? You're in the right place. This will speed up your understanding of Couchbase.  It’s not intended to evaluate all the features or performance.  Since Oracle is a relational database with SQL as the main query language, it's normal for developers to view other databases from SQL point of view. In this article, we'll compare and contrast Oracle with Couchbase from SQL point of view.  You'll get a good feel for the architecture and capabilities of Couchbase. We won't do ... Read More

Feed: R-bloggers. Author: R on The broken bridge between biologists and statisticians. This is a follow-up post. If you are interested in other posts of this series, please go to: https://www.statforbiology.com/tags/drcte/ In the previous post we have shown that time-to-event curves (e.g., germination or emergence curves) can be used to describe the time course of germinations/emergences for a seed lot (this post). We have also seen that the effects of experimental factors on seed germination can be accounted for by coding a different time-to-event curve for each factor level (this post). In this post, we would like to consider the ... Read More

Feed: Planet PostgreSQL. If PostgreSQL had the ability to give to a privileged non-superuser the right to administer objects belonging to some designated group of superusers just as if the privileged account were superuser, it would get us much closer to a world in which the database can be effectively administered by a non-superuser. A highly privileged user - let's call him sauron - could be given the right to administer tables, schemas, functions, procedures, and a variety of other objects owned by dependent users witchking and khamul just as if sauron were superuser. sauron might indeed feel himself to be virtually ...
