To **stop duplicating company data**, records need to live in one place and be referenced from everywhere else. In **Jestor**, you register an employee or a client once, and every later record pulls that data instead of retyping it.

## Why the same record gets typed five times

Disconnected spreadsheets force repetition. The client exists in the sales file, again in the billing file and a third time in the support file, each version slightly different.

That is not a discipline problem. It is a structural one: there is no link between the files, so copying is the only way to reuse anything.

What duplication costs in practice:

- Three versions of the same client with different addresses
- Reports that never match between areas
- Time lost retyping data that already exists
- No single place to see a person's full history

## How relational data changes the structure

| Concept                | How it works                               | Practical effect                                 |
| ---------------------- | ------------------------------------------ | ------------------------------------------------ |
| Single registry        | Each person or company exists in one table | One source of truth per entity                   |
| Connected field        | Other records point to that registry       | Pull the data instead of typing it               |
| Consolidated history   | The card gathers everything linked to it   | Full context without opening five files          |
| Cross area connection  | Different processes reference each other   | A maintenance ticket links to a purchase request |
| Formulas across tables | Calculations read connected records        | Totals that update on their own                  |

## Step by step to structure it

1. **List your core entities**: clients, suppliers, employees, products.
2. **Create one table per entity**, with a single record for each real world item.
3. **Replace free text fields with connected fields** in every process that references those entities.
4. **Link related processes**, such as a maintenance request that generates a material purchase.
5. **Open a card and check the history tab**, confirming everything related is visible in one place.

## Why this matters beyond tidiness

- **Reports finally agree:** every area reads the same record
- **Onboarding gets faster:** a new hire finds context without asking around
- **Automations become reliable:** a rule can trust the data it reads
- **Permissions get precise:** access is granted per field, not per file

## Frequently Asked Questions

### What is a connected field?

It is a field that references a record in another table instead of storing a copy of it. See more at [jestor.com](https://www.jestor.com/?ref=blog.jestor.com).

### Can I see everything linked to one client in a single place?

Yes. Opening the record shows the full history of what is connected to it.

### Does this require a database specialist?

No. Tables and relations are created in the interface, with no code involved.
