Mark Davis MA Datit Productions, LLC
Thirty years spent untangling databases, plotting mysteries, and chasing down songs — because apparently one kind of puzzle was never enough.
Thirty years of Oracle, most of it on systems other people depended on and nobody was allowed to break. Now retired from full-time work and available for selected engagements.
An outside consulting firm compared the utility billing architecture to SAP — favorably.
Published under the name MA Datit. The Hannah D Mysteries are middle-grade adventures set among the ruins of ancient civilizations, where every clue is planted in plain sight and the reader can check the work.
Middle grade — the Hannah D Mysteries
Adult
Breakfast with Costa Rican Critters — a travel article written while researching the second Hannah D book — was published in the Philadelphia Inquirer.
Songs about life's experiences — everyone getting a web page, a man who wanders everywhere without leaving his house, living in Philadelphia, a song about wanting to go to school with Harry Potter. All songs are copyrighted; enquiries about publication are welcome.
Mark Davis is a database engineer and architect with more than thirty years of Oracle experience. At Pedernales Electric Cooperative he spent fourteen years as project manager, architect, and lead developer of an enterprise utility billing platform — an architecture an outside consulting firm compared favorably to SAP.
From 2015 until his retirement he led database modernization at Our Town America in Clearwater, Florida, carrying production systems from Oracle 12c through 23ai and onto Oracle Cloud Infrastructure while modernizing the application stack from PHP 5 to PHP 8.
He holds an M.S. in Management Information Systems from Southern Illinois University and a B.A. in Economics from the University of Colorado.
He writes middle-grade mysteries under the name MA Datit — the Hannah D series, set among the ruins of ancient civilizations — along with an adult travel book and a catalog of songs.
The two halves are less separate than they look. A production database and a fair-play mystery are both things where every piece has to earn its place, and somebody can check your work.
He lives in Treasure Island, Florida.
