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 ...

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: Neo4j Graph Database Platform. Author: Andreas Kollegger. Surely the most exciting part of Web3 is that it brings us closer to Web4j, which will be entirely based on property graphs. Past decentralization, a great thing about graphs is that they have no center, or equally that every connected member is a center (has centrality). You are a center. The web will fold around you into your own pocket universe of information, applications, and transactions.

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: Redis. Author: Ross Owens. If you believe Ralph Waldo Emerson, a foolish consistency may be the hobgoblin of little minds, but when it comes to implementing a scalable, successful enterprise-level caching strategy, there’s nothing foolish about consistency. In fact, one of the greatest challenges in managing the operation of an enterprise database is maintaining cache consistency. Why do we bother with caches in the first place? The principal advantage of an enterprise cache is the speed and efficiency at which data can be accessed. While each call to the primary database can be expensive in terms of both time ... Read More

Feed: Neo4j Graph Database Platform. Author: Enzo. Welcome back, everyone, and welcome to 2022! 2021 flew by like no other (arguably faster than 2020, I’d say).
