Legacy Software Limited

Know what your systems hold. Name it once. Use it everywhere.

Your organisation runs on data that few people can see and fewer can describe the same way. We document your applications and give everyone, from developers to auditors, one agreed business vocabulary linked to every system and document.

In brief

Decisions rest on facts, not folklore.Every answer is traced to the source code and the rule that produced it, so you can sign it off and show it to a regulator.

IT and the business finally speak the same language.One agreed vocabulary is shared by systems, policies, reports and catalogues, so meetings stop arguing about what a field means.

Nothing is replaced and nothing is disrupted.Both products read what you already have, so production systems keep running untouched.

Two products, one picture

Document what you have. Agree what it means.

Use either product on its own, or both together: the Directory tells you what exists and where, and the Workbench tells everyone what it means.

Answers: what do we have, and what uses it?

The Legacy Directory

Your applications are documented automatically and kept current, because the Directory reads the source rather than relying on what people remember.

  • Change with confidence, because you can see every program, job and file a change will touch before you make it.
  • Avoid failures from lost code, because references to members that no longer exist are flagged.
  • Plan migrations on facts, because complexity is measured for every program, application and system.
About the Directory
Answers: what does it mean, and what should we call it?

Naming Workbench

Your whole organisation shares one vocabulary, because every business term is agreed once and linked to the systems and documents that use it.

  • Anyone can find the right name in seconds, because a search page turns a business term into its agreed name and its technical names.
  • Standards are kept, not just written, because names that break your rules are rejected with the reason shown.
  • Compliance and audit see the same picture as IT, because sensitive data is classified from the vocabulary itself.
About the Workbench

Who it's for

Not just for IT. For everyone who needs to trust the data.

A documented estate and a shared vocabulary pay off wherever people ask what the organisation holds and why.

Compliance & data protection

Answer "where do we hold personal data?" with evidence

Because each field is classified and traced to the programs that use it, subject-access requests and data maps start from fact.

Internal & external audit

Spend audit time on findings, not on fact-finding

Because every name, decision and approval is recorded with who made it and why, the trail is already there when auditors ask.

Business & operations

Read reports in your own words

Because the agreed vocabulary is published company-wide, the terms in policies, procedures and dashboards match the systems behind them.

IT & architecture

Change systems without surprises

Because the Directory maps how data flows between programs, jobs and databases, the impact of a change is known in advance.

Migration & modernisation

Move off the mainframe with the meaning intact

Because business names travel with the export, new systems get readable tables and code from the first day.

Data & AI teams

Give AI context it can use, not guess at

Because the glossary and semantic model are generated from approved names, AI tools work from your definitions.

Why rules-based

Explainable by construction, not by exception.

You can sign off our output because every result is produced by transparent rules you can inspect. Where AI helps, it suggests; your experts decide.

Black-box AI

  • Infers context from incomplete, unstructured code
  • Can't show its working when challenged
  • Confidence without traceability
  • Risk grows with every undocumented decision

Legacy Software

  • Scans and structures the estate before reasoning over it
  • Every output traceable to source and rule
  • Built for audit, governance and regulatory review
  • Decades of hands-on mainframe expertise behind every rule
