Working with Oracle Database in enterprise systems
Oracle Database is a long-established commercial database used in banking, government, telecoms and large corporate systems. We most often work with it when integrating new applications into an existing Oracle estate.
Oracle is powerful and highly configurable, with strong features for high availability, partitioning and very large data volumes. It is also expensive to license and administer, and much of its value sits in specialist features that smaller projects never use. For new builds we rarely recommend it unless an organisation already has Oracle expertise and contracts. Where it is in place, we build APIs and services around it, modernise PL/SQL carefully and plan migrations to PostgreSQL where the business case is clear.
What we build with Oracle Database
- API layers over existing Oracle data
- PL/SQL review and refactoring
- Reporting and data extraction pipelines
- Performance investigation
- Migration planning to PostgreSQL
Oracle Database questions
Can you build a modern app on top of our Oracle database?
Yes. A common approach is a service layer that exposes Oracle data through a clean API, so new web and mobile apps never touch the database directly.
Is migrating from Oracle to PostgreSQL realistic?
Often, though effort depends heavily on how much PL/SQL and Oracle-specific functionality is involved. We assess that first and migrate in stages to limit risk.
How are Oracle databases backed up?
Oracle Recovery Manager (RMAN) handles full and incremental backups and supports point-in-time recovery using archived redo logs. We verify that backups restore cleanly rather than trusting job success messages.
What is Data Guard in Oracle?
Data Guard maintains standby databases that stay in sync with the primary and can take over after a failure or during maintenance. It is a common basis for disaster recovery in Oracle estates.
How do you investigate Oracle performance problems?
We use execution plans and Oracle's workload reports, where licensed, to identify the statements and waits consuming most resources. Fixes typically involve indexing, statistics, SQL rewrites or partitioning.
How does Oracle licensing affect our architecture?
Oracle licensing is often tied to processor counts and specific options, so adding servers or features can change costs. We check licence implications before proposing changes such as extra replicas or cloud moves.
Can Oracle data feed a modern analytics platform?
Yes. We extract data through scheduled jobs or change data capture into a warehouse or lake, so reporting no longer loads the transactional database. The source system stays unchanged.
How do you make PL/SQL code easier to maintain?
We put packages under version control, add automated tests around critical procedures and document behaviour before refactoring. Logic that belongs in the application is moved out gradually.
How is sensitive data protected in Oracle?
Oracle offers transparent data encryption, fine-grained access control and auditing, though some are separately licensed options. We combine what you hold with least-privilege accounts and encrypted connections.
Can Oracle run in the cloud?
Yes. Oracle runs on Oracle's own cloud and on other major clouds, either self-managed on virtual machines or through managed offerings. Licensing rules differ between these options, so we check them early.
