1. Teradata SQL

Teradata SQL is the heartbeat of Vantage. It extends standard SQL with features tuned for massive parallelism, big scans, and wide joins. You use it to shape data, interrogate it, and make it sprint instead of stumble.

Why It's Important

Because a Teradata system rewards smart SQL. The optimizer is powerful, but it thrives on good signals—statistics, distribution, partitioning. Strong SQL chops turn petabytes into answers without melting spool or burning the clock.

How to Improve Teradata SQL Skills

1. Filter early: Push predicates down. Trim rows before joins. Don’t cart data around just to toss it later.
2. Tune joins: Join smaller, well-distributed tables first. Use join conditions that avoid product joins. Watch join order and data redistribution.
3. Collect stats: Keep stats current on join columns, predicates, and partitioning. The optimizer can’t guess what it can’t see.
4. Partition wisely: Use row partitioning for time ranges and common filters. Prune partitions; shrink scans.
5. Choose the right index: Pick a primary index that evens out data across AMPs. Add secondary or join indexes only when they earn their keep.
6. Mind OLAP functions: Window functions are brilliant but heavy. Use them on trimmed sets and with tight partitions/orders.
7. Right-size spool: Limit columns, avoid SELECT *, and project only what you need.
8. Volatile and temp tables: Helpful staging, but keep them lean, indexed (if needed), and short-lived.
9. Inspect plans: Read EXPLAIN. Look for redistribution, skew, single-AMP vs. all-AMP steps, and spool consumption.
10. Iterate: Measure, tweak, re-measure. Small changes cascade on large data.

2. BTEQ

BTEQ (Basic Teradata Query) is the old reliable. Scriptable, automatable, perfect for running SQL batches, exports, and quick admin tasks from the command line.

Why It's Important

It stitches environments together. From nightly jobs to ad-hoc fixes, BTEQ lets you run SQL with control, conditionals, and predictable output. Simple. Solid. Still everywhere.

How to Improve BTEQ Skills

1. Go batch-first: Automate with parameterized scripts. Keep them idempotent and restart-friendly.
2. Handle errors: Use .IF ERRORLEVEL, .LABEL, and exit codes. Trap failures fast and fail loudly.
3. Control sessions: Log on once, reuse where possible. Keep session counts sane to avoid thrash.
4. Trim output: .SET WIDTH, .SET TITLES OFF, and selective .EXPORT to reduce I/O and clutter.
5. Group work: Use BT/ET for transactional blocks when needed. Don’t overbatch; avoid runaway rollbacks.
6. Parallelize with intent: Split independent jobs into separate sessions when the system can absorb it.
7. Keep secrets safe: Externalize credentials and use secure mechanisms; never hardcode.
8. Document: Inline comments and a short header explaining inputs, outputs, and restart points.

3. FastLoad

FastLoad is built for speed—loading big volumes into empty tables. It bypasses many niceties to dump data in fast. Many teams now favor TPT Load, but FastLoad still shows up in mature estates.

Why It's Important

Bulk ingest sets the pace for downstream analytics. When loads fly, reports don’t lag and users stay happy.

How to Improve FastLoad Skills

1. Keep targets empty: FastLoad is for empty tables. Stage elsewhere if you need merges.
2. Lightweight DDL: Drop secondary indexes, referential constraints, and triggers before loading; recreate after.
3. Match data types: Align source formats to table definitions to avoid costly conversions.
4. Tune sessions: Start near the number of AMPs, adjust based on system headroom and network conditions.
5. Chunk smart: Use larger, consistent row blocks. Batch rows to cut round trips.
6. Watch skew: Poor primary index choices slow the apply phase. Distribute evenly.
7. Manage error tables: Review ET/UV tables after runs, fix root causes, and clean them up.
8. Prefer TPT when possible: For new work, TPT Load gives more control and better orchestration.

4. MultiLoad

MultiLoad handles bulk inserts, updates, and deletes. It shines on big, repeatable maintenance jobs. Many organizations are migrating this work to TPT Update or Stream operators.

Why It's Important

Because warehouses live in a state of change—late-arriving facts, dimension corrections, churn. Efficient batch maintenance keeps everything consistent without throttling users.

How to Improve MultiLoad Skills

1. Minimize conversions: Align file layouts to table columns; pre-clean before ingest.
2. Right-size sessions: Enough to feed AMPs, not so many that you fight for locks and memory.
3. Reduce locking pain: Group changes by target table and primary index. Avoid hot rows.
4. Balance work tables: Monitor phases and spool; adjust job size to keep apply phases steady.
5. Use checkpoints: Design restartable batches. Partial progress should be recoverable.
6. Purge errors with intent: Triage error tables, fix patterns, reprocess rejects in small, surgical batches.
7. Plan for fallback: Fallback and journaling add overhead; enable only where recovery requires it.
8. Migrate to TPT: New builds should prefer TPT Update/Stream for flexibility and longevity.

5. TPT (Teradata Parallel Transporter)

TPT is the modern toolbox for high-speed data movement. Operators (Load, Update, Stream, Export) run in parallel, pipeline data, and give you fine-grained control over throughput and restartability.

Why It's Important

It replaces a zoo of legacy utilities with one scalable framework. You get consistent logging, better tuning knobs, and jobs that can grow with your platform.

How to Improve TPT (Teradata Parallel Transporter) Skills

1. Pick the right operator: Load for empty-table bulk, Update for DML at scale, Stream for continuous trickle, Export for fast reads.
2. Shape the pipeline: Balance producer and consumer instances. Increase operator instances until you hit system limits, then back off.
3. Tune buffers: Bump buffer sizes and data packing to reduce network chatter.
4. Filter upstream: Push predicates to sources. Move less, win more.
5. Schema discipline: Define SCHEMA blocks precisely; keep layout and table DDL in sync.
6. Design for restart: Use job variables, checkpoints, and clear log paths. Make partial reruns safe.
7. Orchestrate: Break monoliths into smaller, dependency-aware jobs. Parallelize where tables don’t contend.
8. Watch the meters: Track rows/sec, AMP skew, CPU, I/O, and spool. Tune, retest, repeat.

6. Teradata Studio

Teradata Studio is your IDE for Vantage. Query, browse objects, run EXPLAIN, debug scripts, and manage connections without juggling a dozen tools.

Why It's Important

Because fast feedback loops matter. A good workspace helps you iterate SQL, review plans, and keep schemas tidy—without fighting the tooling.

How to Improve Teradata Studio Skills

1. Customize the workspace: Connection profiles, result-set limits, formatting, and color themes that keep you focused.
2. Live in EXPLAIN: Use Visual Explain and query history to find skew, redistributions, and heavy steps.
3. Snippets and templates: Build reusable blocks for DDL, common joins, and diagnostics.
4. Shortcuts: Learn the keystrokes for run, explain, format, and navigate. Seconds saved, hours gained.
5. Result control: Paginate, stream, and export with intent. Don’t dump millions of rows to the grid.
6. Version your SQL: Keep scripts in source control. Treat DDL and DML like code.

7. QueryGrid

QueryGrid lets Teradata reach out—query other systems and blend the results on the fly. Think cross-platform joins with predicate pushdown, not clumsy data shuffles.

Why It's Important

Data sprawls. QueryGrid taps it where it lives, cutting copies and latency. You analyze across engines without building fragile pipelines for every question.

How to Improve QueryGrid Skills

1. Reduce data movement: Push filters and projections to the source. Join small-to-large, not large-to-large.
2. Use smart join strategy: Reorder joins so the smallest sets move. Broadcast when tiny, shuffle when you must.
3. Maintain stats: Keep statistics fresh on participating tables to help the optimizer choose sane paths.
4. Tune links: Right-size bandwidth, concurrency, and timeouts per connector and workload.
5. Parallel transfers: Enable parallelism between systems, but watch for network saturation.
6. Secure credentials: Centralize secrets, rotate them, and audit access.
7. Observe and adjust: Monitor latency, rows pushed down, data returned, and AMP impact. Fix hotspots quickly.

8. Data Warehousing

Warehousing means corralling data from many places into a model that answers questions fast and reliably. On Teradata, that means designs that play nicely with parallel hardware and heavy concurrency.

Why It's Important

Good models reduce work for every query. Bad ones waste cycles forever. The difference shows up on every dashboard and every SLA.

How to Improve Data Warehousing Skills

1. Model for access: Normalize where write-speed and integrity matter; denormalize where read-speed wins. Star schemas shine for analytics.
2. Partition for time: Row partition large fact tables by date or range. Prune, compress, and archive with grace.
3. Index with restraint: Sensible primary index choice first; secondary and join indexes only when measured benefits appear.
4. Compress: Use multi-value and block-level compression to cut I/O. It’s free speed when chosen wisely.
5. SLA-driven zones: Separate workloads and service levels with proper resource groups and workload management.
6. Governance: Add lineage, audit columns, and clear naming. Future you will thank present you.

9. ETL Processes

ETL (or ELT, more and more) is the plumbing. Extract data, shape it, land it, and keep it clean. On Teradata, parallelism is your friend, and idempotency is your shield.

Why It's Important

Without robust pipelines, beautiful models starve. ETL quality dictates data quality, and data quality dictates trust.

How to Improve ETL Processes Skills

1. Lean into parallel: Split big jobs by time slices, keys, or tables. Let AMPs do the heavy lifting.
2. Incremental over full: CDC, hashes, high-water marks. Move only what changed.
3. Stage smart: Land raw, refine to curated, publish for consumption. Clear contracts between layers.
4. Validate relentlessly: Row counts, checksums, referential checks, and anomaly flags. Fail fast, fail loudly.
5. Idempotent design: Safe reruns with upserts, merge patterns, and checkpointing.
6. Right tool for the job: TPT for movement, SQL for transforms, BTEQ for orchestration glue. Keep it simple.
7. Batch sizing: Tune batch sizes to balance throughput and resource pressure. Measure, don’t guess.
8. Error isolation: Quarantine bad records, log context, and reprocess in tiny, targeted retries.

10. Viewpoint

Viewpoint is the web console for monitoring and managing Teradata. Dashboards, portlets, alerts, workload controls—the nerve center.

Why It's Important

You can’t tune what you don’t see. Viewpoint surfaces the signals: CPU, I/O, skew, spool, long runners, blocked locks. It’s where you spot trouble and prove improvements.

How to Improve Viewpoint Skills

1. Curate dashboards: Build role-based views—operations, DBA, developer. Only the metrics that matter.
2. Set alert thresholds: Proactive notifications for skew, spool pressure, CPU spikes, and runaway sessions.
3. Workload management: Tune rules so critical dashboards stay snappy while heavy ETL waits its turn.
4. Query drill-down: Follow a bad query from session to step to object. Coach developers with evidence.
5. Capacity trends: Track growth, spot seasonality, plan headroom before it’s gone.
6. Housekeeping: Rotate logs, review top offenders, and retire stale portlets and dead alerts.

11. Teradata Aster

Teradata Aster powered advanced analytics—SQL-MR, graph, path—across big data sets. Many of those capabilities have since moved into Teradata Vantage, but Aster skills still translate.

Why It's Important

It blends SQL with analytic engines, letting teams run complex patterns close to the data. If your shop still runs Aster or has ported workloads to Vantage, this background pays off.

How to Improve Teradata Aster Skills

1. Design for MPP: Partition data where your algorithms slice naturally. Keep nodes busy, not waiting.
2. Use built-ins: Prefer native SQL-MR and graph functions before rolling custom code.
3. Optimize access: Columnar storage and selective projections cut I/O dramatically.
4. Stage features: Precompute features for heavy models; cache intermediate results where stable.
5. Migrate with purpose: Map Aster functions to Vantage equivalents and validate with side-by-side tests.

12. Unity Director

Unity Director (now part of Teradata Unity) manages multi-system routing, availability, and consistency. It keeps users online during failures and balances workload across clusters.

Why It's Important

High availability isn’t optional. Unity steers queries to healthy systems, coordinates failover, and protects consistency across environments.

How to Improve Unity Director Skills

1. Know your topologies: Active/active vs. active/standby, sync vs. async. Design to the SLA, not wishful thinking.
2. Craft routing rules: Route by user, app, workload, or object. Keep critical traffic on the shortest path.
3. Tune heartbeats: Right-size timeouts and probes so failovers are fast but not flappy.
4. Plan consistency: Choose commit and replication behaviors that match tolerance for staleness.
5. Drill failover: Rehearse. Validate client transparency, transaction safety, and recovery times.
6. Watch lag: Monitor replication delay, apply queues, and conflict handling. Fix drift early.
