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. ![[20260903-business-general-ledger.png]] 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]].
