Conceptual information

What business information does the application manage, and how are those concepts related?

This view models the named business information concepts supported by generated record artifacts, form fields, help text, and invoice-related structures. The evidence supports separate customer, order, order-item, stock-item, and invoice concepts, but it does not prove a live database schema or runtime persistence. E0004E0006

Relationships are shown only where the evidence supports a specific semantic connection. No multiplicity is stated because the supplied evidence does not establish reliable cardinalities, except that documented order entry supports up to ten line items; this is an interface limit, not necessarily a database cardinality. E0004

Elements

Customer

Kind: entity

Basis: reported

Description: A customer record includes customer number, names, company, address, city, state, ZIP code, and phone information. The order structures also carry a customer number. E0004E0006

Evidence: E0004E0006

Order

Kind: entity

Basis: reported

Description: An order record includes order number and date, customer number, shipping instructions, backlog, purchase-order number, ship date, shipping weight and charge, and paid date. E0004E0006

Evidence: E0004E0006

Order Item

Kind: entity

Basis: reported

Description: The generated item structure includes item number, stock number, manufacturer code, description, quantity, unit price, and total price. The order-form structure presents these as order-line information. E0006

Evidence: E0006

Stock Item

Kind: entity

Basis: reported

Description: Stock-related structures include stock identifiers and item attributes such as description, unit, unit price, and manufacturer information. The evidence describes stock management as a separate module responsibility. E0004E0006

Evidence: E0004E0006

Invoice

Kind: entity

Basis: reported

Description: The generated X_Invoice structure combines order-, item-, stock-, and manufacturer-related fields, supporting an invoice-oriented business record distinct from the order and stock-item records. E0006

Evidence: E0006

Relationships

Customer places Order

From: Customer

To: Order

Relation: relates_to

Basis: reported

Description: Order structures contain a customer number, and the documented order-entry flow supports adding orders for existing customers. E0004E0006

Evidence: E0004E0006

Order has Order Item

From: Order

To: Order Item

Relation: relates_to

Basis: inferred

Description: Order-form structures expose order-line fields for item number, stock number, description, quantity, price, and total, while the generated item structure contains the corresponding item attributes. This supports an order-to-order-item relationship, but no database foreign-key declaration is supplied. E0006

Evidence: E0006

Order Item references Stock Item

From: Order Item

To: Stock Item

Relation: relates_to

Basis: inferred

Description: The order-item structure contains a stock number, and the stock-related structures contain stock and item attributes. This supports a conceptual reference from an order item to a stock item, without establishing persistence or referential constraints. E0004E0006

Evidence: E0004E0006

Invoice summarizes Order

From: Invoice

To: Order

Relation: relates_to

Basis: inferred

Description: The invoice-oriented generated structure combines order-related fields with item and stock information, supporting an invoice relationship to an order. The evidence does not establish whether an invoice is generated for every order or only for selected orders. E0006

Evidence: E0006

Invoice includes Order Item

From: Invoice

To: Order Item

Relation: relates_to

Basis: inferred

Description: X_Invoice combines invoice-related data with item fields such as item number, quantity, unit price, and total price, supporting a conceptual invoice-to-order-item relationship. E0006

Evidence: E0006

Invoice references Stock Item

From: Invoice

To: Stock Item

Relation: relates_to

Basis: inferred

Description: The invoice-oriented structure also combines stock-related fields with order and item fields, supporting a conceptual relationship between an invoice and stock items. E0006

Evidence: E0006

Gaps

The supplied evidence does not establish live database tables, keys, foreign-key constraints, persistence behavior, or successful SQL execution; the generated record classes are only schema-like evidence. E0006

No multiplicities are established for customer-to-order, order-to-item, item-to-stock, or invoice relationships. The documented limit of up to ten order line items describes order entry, but does not prove a persistent cardinality. E0004

The evidence distinguishes Order.java and Orderform.java as different order-form variants, so their relationship to one another and to the runtime model remains unresolved. E0006

Customer behavior is incompletely assessable because one analysis reports customer form fields, while another states that the expected Customer.java.svn-base contents are absent from the supplied evidence. E0004E0006

The evidence does not define whether invoices are generated, stored, or merely represented by a generated record structure. Further source coverage for persistence, invoice processing, and record relationships is required. E0006
