After logging on, Invantive Business for Windows shows the Explorer: the tree on the left names the subjects available, and what is chosen there opens on the right.
![[20260809-business-explorer.png]]
The title bar states who is working in which database, in the form `Explorer - [<user>@<group>\<database>: <full name>]`, so that it stays visible which data is on screen. A platform which knows no user, such as an XML audit file, leaves the part before the `@` empty.
## Menu
The menu bar carries five entries:
- "File": leaving the product; see [[File]].
- "Edit": refreshing the subject on screen; see [[Edit]].
- "Development": the SQL engine underneath; see [[Development]].
- "Connection": connecting elsewhere, and the settings of this device; see [[Invantive Business/Menu/Connection|Connection]].
- "Help": the documentation, the licence and the details of this installation; see [[Help]].
The whole menu is described in [[Invantive Business/Menu/Menu|Menu]].
## Company
Under the menu sits "Company" with the companies of the connected database. A company is one company, one administration or one file, depending on the platform; the choice made here decides which data the subjects below show. See [[Invantive Business/Concepts/Companies|Companies]] and [[Choose a Company]].
To the right sits a search field which searches the subject currently open.
A dot to the left of the search field says how much of the recent past was spent waiting on the platform, background traffic included.
## Subjects
The tree holds the subjects the [[Business Drivers|Business driver]] offers. Which of them carry data depends on the platform connected to: a subject a platform knows nothing of stays empty rather than disappearing.
- "Dashboard": the opening view, and the root of everything below it.
- "Persons": the people known on the platform, from `BUS_PERSONS_R`; see [[Persons]].
- "Organizations": the companies and other parties, from `BUS_ORGANIZATIONS_R`; see [[Invantive Business/Subjects/Organizations|Organizations]].
- "Documents": the documents held with the data, from `BUS_DOCUMENTS_R`; see [[Invantive Business/Subjects/Documents|Documents]].
- "Companies": the companies the connection offers, from `BUS_PARTITIONS_R`. The entry carries the name the platform uses for it, so it reads "Partitions" on a platform which offers no name of its own; see [[Invantive Business/Subjects/Companies|Companies]].
- "General Ledger": the financial administration, holding "VAT Codes", "Cost Centres", "Cost Units", "General Ledger Accounts", "General Ledger Journals", "General Ledger Years", "General Ledger Periods", "General Ledger Transactions" and "General Ledger Transaction Lines".
- "Marketing", "Sales", "Human Resource Management" and "Manufacturing": each holding "Articles".
- "Inventory": "Articles" and "Warehouses".
- "Projects": "Projects".
The nine subjects under "General Ledger" are the financial heart, and follow the order in which they build on one another: first what classifies a booking, then the accounts and journals, then the years and periods, and last the transactions and their lines.

Every subject is described in [[Subjects]].
A module which has no subject under it at all is a sign of missing rights rather than of missing data; see [[No Subjects Under a Module]].
