Discuss your requirements ↗AI CONSULTING & DATA FOUNDATIONS
Make AI useful.
Start with data you can trust.
Put your databases, documents and operational knowledge to work. CTRD helps you assess AI opportunities, design secure integrations and build focused pilots with clear success criteria.
Start with a specific task: finding the right runbook, preparing an incident summary, extracting document data or answering questions from approved business information.
Discuss an AI assessment ↗01 / ASSESS
AI readiness & roadmap
Find a useful starting point before choosing a model or platform. Review business goals, available data, access constraints and the work your team wants to improve.
What the engagement can include
- Prioritized use cases and data readiness findings
- Architecture options, risks and indicative operating costs
- A pilot scope with measurable acceptance criteria
02 / RETRIEVE
Knowledge assistants & RAG
Help staff find answers in approved runbooks, procedures and business documents. Retrieval-augmented generation (RAG) supplies relevant source material to an AI assistant.
What the engagement can include
- Permission-aware retrieval and source references
- Document ingestion, refresh and removal design
- Evaluation of answer quality and unsupported questions
03 / PREPARE
Data foundations & vector search
Prepare database and reporting data for AI use. Connect existing platforms to controlled retrieval and analytics workflows without giving a model unrestricted production access.
What the engagement can include
- Data quality, ownership and freshness checks
- Embeddings and vector search architecture, including PostgreSQL options
- Read-only access patterns, masking and workload isolation
04 / ASSIST
AI-assisted database operations
Use AI to help summarize alerts, search runbooks and draft incident updates or tuning recommendations. Keep technical validation and production decisions with your team.
What the engagement can include
- Alert and log summarization from approved sources
- Draft procedures, incident summaries and investigation steps
- Reviewed recommendations and controlled execution paths
05 / CONNECT
Workflow agents & document processing
Develop focused pilots that extract information from documents, prepare reports or coordinate tasks across approved systems. Define what an agent can read, draft and do.
What the engagement can include
- Workflow mapping and scoped system integrations
- Validation of extracted fields and exception handling
- Approval checkpoints, action logs and human handover
06 / VALIDATE
Evaluation & operational readiness
Make the decision to expand a pilot on evidence. Review answer quality, permissions, latency, operating costs and support responsibilities before production rollout.
What the engagement can include
- Representative test cases and quality thresholds
- Access, retention and model-provider configuration review
- Monitoring, fallback procedures and documented handover
FROM QUESTION TO WORKING PILOT
A clear decision at every stage.
- Define the taskAgree users, data sources, boundaries and what success means.
- Build & evaluateTest a limited pilot against real questions and approved sample data.
- Decide & hand overReview results, costs and risks. Agree the next step and operating responsibilities.
Your data. Clear permissions. Human accountability.
Agree model providers, data residency, retention and access before connecting information. Design production changes and external actions to require authorized approval. Evaluate retrieved content and model responses, with a fallback when the system cannot answer reliably.
Do we need to replace our databases or build a model from scratch?
Begin with your existing environment and the task to solve. An assessment can compare managed models, retrieval over approved data and available database capabilities. A new platform or custom model is considered only when the requirements justify it.
Delivery scope, supported platforms, provider charges and ongoing support are agreed for each engagement. Cloud and model usage costs are assessed separately.
Contingency DBA services
A second senior DBA.
When your business needs one.
Another full-time senior DBA may be difficult to justify. Yet vacations, unexpected absences and complex projects still call for experienced backup. CTRD provides a secondary resource who becomes familiar with your environment, supports your primary DBA and adds capacity when needed.
CONTINUITY & COVERAGE
Support for your primary DBA
Reduce dependency on a single person while keeping your existing team at the centre of operations.
- Planned vacation and temporary absence coverage
- Additional capacity during projects and workload peaks
- Specialist help with difficult incidents
- Vendor escalation and technical follow-through
VALUE BETWEEN COVERAGE PERIODS
Keep improvement work moving
Use agreed consulting time to advance work that daily operations can push aside.
- Runbooks, procedures and knowledge transfer
- Health reporting and alert reviews
- Backup audits and scheduled restore testing
- Performance tuning and maintenance preparation
PLANNED & PRACTICAL
Ready through onboarding
Establish environment knowledge before coverage is needed, with clear responsibilities and a documented handover.
- Review systems, dependencies and priorities
- Agree secure access and operating procedures
- Define coverage windows and escalation paths
- Schedule familiarization and ongoing updates
Availability, notice periods, coverage and response expectations are agreed in advance. Onboarding supports continuity; it does not imply automatic 24/7 or immediate emergency availability.
HOW WE WORK

PERSPECTIVES / PRACTICAL GUIDES
Better questions.
Better database decisions.
Short guides for IT leaders planning coverage, recovery and technology change. General guidance, with the details shaped around your environment.
Who covers your database when your DBA is away?
Continuity starts before an absence. Access, context and decision-making authority need preparation.
Read the guide
- Can a secondary resource securely access the environment and find current operating procedures?
- Are backup checks, scheduled work and incident escalation clearly assigned?
- Has a handover been rehearsed, with agreed availability and approval boundaries?
Start with familiarization, a current runbook and planned coverage windows. Use work between coverage periods to keep environment knowledge current.
When was your last successful restore test?
A completed backup job is useful evidence. A validated restore answers a different business question.
Read the guide
Agree what must be recovered and the acceptable interruption. Test a restore in an isolated environment, record elapsed time, validate the recovered database and check application dependencies.
Document gaps, assign owners and repeat tests on a schedule appropriate to the system. A successful test supports readiness; it is not a guarantee for every incident.
Before moving the database, map the dependencies.
A platform decision needs more than an engine name and a storage estimate.
Read the guide
Inventory application connections, jobs, integrations, code, permissions and recovery requirements. Check compatibility and tooling before setting a cutover plan.
Rehearse migration and reconciliation, validate application behavior and define rollback decision points. Treat an online timeline estimate as a discovery aid, not a delivery commitment.
PLANNING WORKBENCH
Turn a technical question
into a useful conversation.
Explore an initial migration allowance, then carry your selections into the inquiry form. The estimate is illustrative and needs a scoped review.

TECHNICAL RESOURCES
Practical questions.
Useful starting points.
Transparent diagnostic approaches and a small read-only inventory query. These are general references, not published client post-mortems or measured benchmarks.
REPLICATION / INVESTIGATION CHECKLIST
When replication lag rises, where do you start?
Separate source capture, transport and target apply. Track the backlog over time, then correlate it with workload changes and resource pressure.
Inspect the investigation sequence
- Establish when lag started and what changed.
- Check capture progress, trail growth and process errors.
- Review DNS, connectivity and transport behavior.
- Inspect target apply throughput and warehouse contention.
- Validate data consistency before declaring recovery.
Metrics to collect: capture lag, apply lag, backlog growth and target throughput. No benchmark is assumed.
