A computer monitor, likely a laptop screen, is captured displaying the MySQL Workbench application with an Enhanced Entity-Relationship (EER) Diagram in view. The screen's upper section shows the application title "MySQL Model | EER Diagram | Modelo1.mwb - MySQL Workbench." The EER diagram occupies the majority of the display's right side, rendered on a light grey grid background. Four distinct entity tables are depicted: "Productos," "Compras_has_Productos," "Clientes," and "Compras." The "Productos" table lists attributes including `idProductos` (INT, Primary Key), `Descripcion` (VARCHAR(45)), `Existencia` (INT), `Pcompra` (DECIMAL), `Pventa` (DECIMAL), `Incremento` (FLOAT), `Numcat` (INT), and `Categorias_idCategorias` (INT, Foreign Key). The "Clientes" table includes `idClientes` (INT, Primary Key), `Nombre` (VARCHAR(45)), and `Telefono` (VARCHAR(45)). The "Compras" table contains `idCompras` (INT, Primary Key), `Clientes_idClientes` (INT, Foreign Key), and `Clientes_idClientes1` (INT, Foreign Key). The "Compras_has_Productos" table, acting as a junction, has composite primary and foreign keys: `Compras_idCompras` (INT), `Compras_Clientes_idClientes` (INT), `Compras_Clientes_idClientes1` (INT), and `Productos_idProductos` (INT). Lines with cardinality notations illustrate relationships between these tables: "Clientes" relates to "Compras" (one-to-many), and "Productos" and "Compras" are linked via "Compras_has_Productos" (many-to-many resolved). The left vertical panel of the MySQL Workbench interface shows a "Navigator" section and options for "Layers" and "User Types," with a zoom level indicator at "100." The screen's surface exhibits minor dust or smudges. The bottom edge of the screen reveals a macOS Dock, displaying icons for various applications including Finder, App Store, Mail, Safari, Chrome, Microsoft Word, Excel, PowerPoint, Photos, Preview, Calendar (showing "SEP 2"), and Messages. The scene is located in the city of San Bernardino Tlaxcalancingo, Mexico.
