Newsletter Changes – from the desk of the Managing Editor
The Database Application Developer Newsletter is changing. This is the first newsletter of that change, and you probably don’t notice much difference. It’s true. Slight tweaks from previous editions, but this one is not too different. BUT! Change is coming. Change to make it better, and more relevant to the topics and news you need. My name is Bill Sawyer, and I am joining as Managing Editor. I have been planning some exciting changes. But, this doesn’t have to be a one-way conversation. Do you have thoughts on what you want to see? Email me at bill.sawyer@oracle.com |

Code You Can Use
Martin Bach wrote a nice piece titled, Generating Table DDL in Oracle Database. This blog showcases how you can easily generate DDL statements using SQLcl 22.1.1.0 connecting to a 19c Autonomous Transaction Processing. There are lots of new features in SQLcl 22.1.1.0, and this is some code you probably want to keep in your bookmarks. If you want to know more about SQLcl 22.1.1.0, check out Jeff Smith’s blog post, Oracle SQLcl 22.1 is now available & featuring Data Guard!, on the topic.
Tools You Can Use
Daniel Cuadra gives you the latest on Oracle Spatial Studio in his blog, Upgrading to Oracle Spatial Studio 22.1. Oracle Spatial Studio provides no-code access to spatial data preparation, analysis and visualization. It allows you to work with data already in Oracle Database or load from common spatial and non-spatial formats. Non-spatial data can be prepared by address geocoding or coordinate indexing and then used for spatial analysis and mapping. Results may be shared as interactive maps as well as GeoJSON endpoints for programmatic integration. |

Developer Success Story Pablo Duque’s NeuroBase helps neurorehabilitation experts improve the patient experience. Neurorehabilitation is a physician-supervised program designed for people with diseases, trauma, or disorders of the brain, such as Parkinson’s disease, and it generates a lot of data. Pablo saw a need to process that data and, in his words, “There was really no good software available to do that.” So Duque made his own tool: NeuroBase using Oracle APEX. |
