This presentation discusses the top 5 reasons as well as various technology updates to provide a reasonable answer to the rather common question: "Why should one use an Oracle Database?". This "2020 "C-Edition" was first presented during the IOUG / Quest Forum Digital Event: Database & tech Week in June 2020 and subsequently updated based on feedback received.

5. Flexible Based on Strong Fundamentals
Structured Query Language
(SQL)
Oracle supports ANSI standard
SQL
Has extensions to the SQL
language for features that are
not included in ANSI standard.
Multiversion
Read Consistency
The data returned by a query is
committed and consistent for a
single point in time.
Nonblocking queries
Readers and writers of data do
not block one another.
Non-escalating
row level locking
Transactions
Supporting transactions means
the database ensures A.C.I.D.

Pluggable Databases (PDBs) providing
- Rapid deployment with Hot Clone
- Refresh / incremental refresh
- Relocation with no downtime
- PDB upgrades (using plug / unplug)
• PDBs enable transparent, simplified online
lifecycle operations for any application
• PDBs speed up database migration to
new container databases (in the cloud)

12. Converged Database
Use cases are converging
12 Copyright © 2020, Oracle and/or its affiliates
Phone calls, messaging, photos, etc.
originally required separate products
• Now they are features of Smartphones
Similarly, ML, JSON, Blockchain, etc.
originally required separate databases
• Now they are features of a Converged Database

13. Use Cases are Converging for Good Reasons
Developers innovate faster with converged
It is dramatically simpler for developers to invoke extended SQL to execute ML, graph, spatial,
blockchain, IoT, etc. in one converged database
Instead of implementing distributed execution and data movement across multiple
fragmented databases

23. Application Continuity
Protect your applications from any interruption
Application outage protection
• For planned & unplanned outages
• System outage protection alone does not
ensure applications are uninterrupted
• Application Continuity continues reads
and replays in-flight database requests
• 100% transparent to the users and
applications – fully automatic
• Unique to Oracle!
• Available with Oracle RAC and Active Data Guard

32. Benefit from Cloud Sizing
All workloads exhibit variation – “normal” to “peak”
• Annual/quarterly/weekly/daily seasonal variations
• Retail/other seasonal transactions,
periodic reports and compliance, full backups
• But also intraday variation
• End-of-day reports, analytics workloads, day/night (e.g., lower daytime workload on
sparsely populated landmasses/Pacific Ocean), incremental backups
• On-premises common to see “peak” sized “2x normal”
• If 16 cores are “normal”, the system may get sized with 32 cores
On cloud, it is safe to provision for normal workloads and burst up as needed
32 Copyright © 2020, Oracle and/or its affiliates

33. Production Workload Sizing
On-premises, size for the peak,
plus additional buffer = lots of idle CPU
