Validation Workflow

How the Data Validation Process Works

The workflow starts with the rules that make your data acceptable, then applies those checks in a controlled sequence so exceptions can be reviewed and traced.

STEP 01

Scope & Rule Capture

Confirm the dataset, purpose, critical fields, expected values, tolerances and output required.

STEP 02

Data Intake & Profiling

Review structure, columns, types, null patterns, duplicates and obvious integrity issues before deeper checks.

STEP 03

Rule Configuration

Translate agreed quality and business requirements into clear, testable validation conditions.

STEP 04

Validate & Reconcile

Run structural, field, relationship and comparison checks according to the confirmed validation scope.

STEP 05

Exception Review

Organize mismatches and rule failures so the issues can be checked against context and source evidence.

STEP 06

Deliver & Handover

Provide the agreed validation output, exception evidence and practical notes for the next action.

Validation Rule Coverage

What Data Validation Can Check

The right validation design depends on what the data represents and how it will be used. Checks can be combined into a rule set that separates structural errors, data-quality issues and business-rule exceptions.

  • Rules are defined before testing so the result has a clear basis.
  • Exceptions can be retained for review instead of silently changing source data.
  • Validation can be scoped for a one-off file, migration check or recurring data flow.

Completeness & Required Fields

Identify blanks, missing mandatory attributes and incomplete records based on the agreed field requirements.

Example rule: customer_id and transaction_date must not be blank.

Types, Formats & Ranges

Check dates, numbers, codes, text patterns, boundaries and field structures against accepted formats.

Example rule: order_date must be a valid date; amount must be non-negative.

Duplicates & Uniqueness

Find repeated identifiers, duplicate rows or combinations that should occur only once.

Example rule: invoice_number must be unique within the supplied dataset.

Allowed Values & Reference Data

Compare fields against approved code lists, categories, master values or reference datasets.

Example rule: status must match the approved status catalogue.

Key & Relationship Integrity

Check whether related records, parent-child keys or lookup values connect as expected across data structures.

Example rule: every order customer_id must exist in the customer reference file.

Cross-Field Business Logic

Test relationships between fields when valid data depends on more than one value or condition.

Example rule: closed_date cannot be earlier than opened_date.

Source-to-Target Reconciliation

Compare mapped source and target records to identify missing rows, mismatches or transformation differences.

Example rule: mapped account_id and approved balance should reconcile across extracts.

Exception Classification

Organize findings by rule, field, severity or review status so the next action is easier to prioritize.

Example output: rule failure, affected field, record key and review note.
Validation by Data Flow

Match the Validation Method to Where the Data Is Going

Validation for a one-off spreadsheet is different from validation for a system migration or reporting feed. The service can be structured around the stage where data quality needs to be proven.

File & Spreadsheet Validation

Useful before uploads, reporting, sharing or analysis when a file needs a defined quality check.

  • Excel and CSV structure
  • Nulls, duplicates and formats
  • Rule and exception review

Database Extract Validation

Useful when SQL or system extracts need consistency checks before downstream use or comparison.

  • Key integrity and allowed values
  • Record-level consistency
  • Reference matching

Migration & ETL Validation

Useful when data moves between systems and source-to-target evidence is needed for mapped fields.

  • Record counts and missing records
  • Mapped field comparisons
  • Transformation exceptions

Reporting & Analytics Validation

Useful before dashboards, models or recurring reports consume data that must meet agreed rules.

  • Critical field checks
  • Business logic consistency
  • Repeatable validation criteria
Data Validation Deliverables

What You Receive After the Validation Review

Deliverables are selected according to the plan and agreed rules. The goal is to give you traceable findings that can be reviewed, corrected or used as evidence for the next data step.

Validation SummaryOverview of the checks performed, scope, assumptions and main findings.
Flagged Dataset / Exception FileRecord-level flags or a separate issue file showing where agreed rules failed.
Mismatch & Reconciliation LogSource-to-reference or source-to-target differences when comparison is included.
Rule Outcome RegisterClear view of rule names, fields tested, pass/review status and relevant notes.
Review NotesContext for exceptions that need a business decision rather than an automatic correction.
Handover GuidancePractical next steps for remediation, retesting or repeatable validation where included.
Before & After Validation

Move From Unchecked Data to Traceable Validation Evidence

Data validation does not guarantee that every source value is correct. It creates a defined basis for identifying where data meets the agreed rules and where review is still required.

Before Validation

  • 1
    Acceptance criteria are unclearTeams may interpret valid values, formats or thresholds differently.
  • 2
    Duplicates and missing values remain hiddenQuality issues can surface later in reporting, migration or operations.
  • 3
    Source and target differences are hard to traceMismatches may be noticed without a structured record of where they occurred.
  • 4
    Issue review is inconsistentExceptions can be handled ad hoc without a common rule or evidence trail.

After Validation

  • Rules are explicitly definedCritical fields, accepted values and comparison logic have a clear test basis.
  • Exceptions are organized for reviewMissing, invalid, duplicate or mismatched records are easier to locate and assess.
  • Reconciliation findings are traceableSource-to-target differences can be linked to specific records, fields or rules.
  • The next action is clearerTeams can decide what needs correction, acceptance, retesting or additional investigation.
Common Data Validation Use Cases

Where a Structured Validation Review Is Most Useful

Validation can be applied whenever data must meet known requirements before it is loaded, shared, reconciled or used to support a business process.

Data Migration

Compare source and target extracts to identify missing records, mapping differences and field-level mismatches.

CRM & Customer Data

Check identifiers, contact fields, duplicates, required values and allowed statuses before upload or use.

Reporting & BI Inputs

Validate critical fields and business rules before data is consumed by dashboards, models or recurring reports.

Product & Catalogue Data

Check required attributes, category values, identifiers, duplicate records and formatting consistency.

Finance & Operational Files

Apply agreed field, amount, date and reference rules before reconciliation, reporting or downstream processing.

Survey & Research Datasets

Review completeness, valid response codes, duplicates and structural consistency before analysis begins.

What We Need From You

Give the Validation Rules a Clear Business Context

Good validation depends on knowing what the data is meant to represent. The more clearly the expected rules are defined, the more useful the exception output can be.

  • The dataset, extract or representative sample to be reviewed.
  • Field definitions, data dictionary or basic column meaning where available.
  • Approved values, mandatory fields, ranges, tolerances and cross-field rules.
  • Reference data, source-to-target mapping or comparison file when reconciliation is required.
  • The intended downstream use so critical checks can be prioritized appropriately.
Practical Outcomes

Why Validate Data Before It Moves Downstream?

A structured validation step can help teams see issues earlier, apply rules consistently and reduce ambiguity when data is handed to another process or system.

Earlier Issue VisibilitySpot rule failures before they are buried in later processing.
More Consistent Quality ChecksUse the same agreed rules across the reviewed dataset.
Clearer ReconciliationOrganize source-to-target differences around records and fields.
Better Review EvidenceKeep a readable record of what was checked and what needs attention.
Easier RepeatabilityDefined rules can support future retesting or recurring validation scopes.
Data Validation FAQ

Questions Before You Start a Data Validation Project

These answers cover the practical details buyers usually need before deciding the right validation scope.

What is data validation?

Data validation is the process of checking whether data follows agreed structural, quality and business rules before it is used for reporting, analysis, migration, automation or operational decisions. Checks can cover completeness, formats, duplicates, valid values, relationships, reconciliation and custom rules.

What types of data can be validated?

The service can be scoped around common business datasets such as Excel or CSV files, database or SQL extracts, reporting exports, source-to-target migration files, CRM or customer records, product data and other structured tabular data. Final scope depends on the file structure, rules and access available.

What checks are included in a data validation project?

Depending on the selected plan and agreed scope, checks can include required fields, nulls, duplicates, data types, formats, ranges, allowed values, key integrity, cross-field logic, reference-data matching, source-to-target reconciliation and custom business rules.

How much does Rudrriv data validation cost?

Data Validation plans start at $15 USD for a focused entry-level dataset check. The $30 and $50 plans add deeper rule testing, reconciliation and reporting. Larger datasets, recurring validation, multiple sources or complex business rules are quoted after scope review.

How long does data validation take?

The standard delivery window is 5–7 working days. Timing can vary with dataset size, file quality, number of validation rules, source-to-target comparisons and how quickly the required business rules or reference data are supplied.

What do I need to provide before validation starts?

Please provide the dataset or a representative sample, the purpose of the data, important field definitions, known business rules, accepted values or tolerances, reference data where relevant and any source-to-target mapping needed for reconciliation.

Can you validate data during a migration or system change?

Yes. A validation scope can compare source and target extracts, record counts, key fields, required values and mapped attributes to identify missing, mismatched, duplicate or invalid records. The exact checks depend on the migration design and evidence available.

Do you fix the data or only identify validation issues?

The primary service is validation and exception identification. Agreed low-risk corrections or a flagged output can be included where appropriate, but large-scale remediation, enrichment or transformation should be scoped separately so changes remain controlled and traceable.

Can you apply our own business rules and tolerances?

Yes. Custom rules can be included when they are clearly defined and testable, such as valid status values, date relationships, amount thresholds, mandatory combinations, uniqueness requirements or reference-data mappings.

What will I receive at the end of the service?

Deliverables depend on the selected plan and can include a validation summary, flagged dataset or exception file, mismatch log, reconciliation findings, rule outcome report and practical notes explaining what was checked and which issues need attention.

Can the service be used for recurring data quality checks?

Yes. If the same dataset or feed needs regular checks, Rudrriv can scope a repeatable rule set, recurring validation cadence and reporting format as a custom engagement after reviewing the data flow and operating requirements.

Should I send sensitive or confidential data in the first enquiry?

No. Use the first enquiry to describe the dataset, approximate size, data type and validation requirement without attaching highly sensitive information. Appropriate file-sharing and handling arrangements can be agreed after the scope is reviewed.
