Phần Phụ lục B giải thích cách tái sử dụng chúng từ sơ đồ này sang sơ đồ khác. Nói cách khác, nếu bạn tạo lớp cho một sơ đồ thì bạn nên có thể sử dụng lại bằng cách chọn lớp đó từ từ điển và kéo rồi thả vào sơ đồ khác. Cuối cùng, một số công cụ tạo mô hình cao cấp (có giá "đắt") cho phép bạn tạo mã từ mô hình của mình. Khi viết những phiên bản trước của cuốn sách này, chỉ có một vài công cụ tạo mô hình UML và tôi đã thảo luận về 3 loại. Kể từ những phiên bản trước, số lượng công cụ tạo mô hình đã tăng đáng kể. Ví dụ có 2 công cụ tôi nghĩ đến là, Together, một công cụ Borland mua gần đây, và Poseidon, sản phẩm của Gentleware. Thay vì khảo sát toàn bộ các loại tôi nghĩ lần này tôi sẽ cho bạn biết cảm giác làm việc với công cụ tạo mô hình như thế nào: tôi sẽ hướng dẫn bạn thực hiện một số bước với một trong số chúng: Microsoft Visio Professional Edition. Nếu bạn quen với Visio thì sẽ hữu ích. Ngay cả khi bạn không hiểu biết gì cả cũng không sao. Làm việc với UML trong Visio Professional Edition Visio Professional Edition, một trong những công cụ lập biểu đồ nổi tiếng nhất, bổ sung thêm một số khả năng liên quan đến UML giúp nó trở thành công cụ tạo mô hình mạnh mẽ một cách đáng ngạc nhiên. UML chỉ là một trong những khả năng của Visio. Tôi sẽ hướng dẫn bạn tạo biểu đồ lớp, biểu đồ đối tượng và biểu đồ tuần tự. Trong quá trình này, tôi sẽ chỉ ra các tính năng của công cụ này. Để cung cấp cho bạn ý tưởng về hướng đi, tôi sẽ bắt đầu bằng cách trình bày những sơ đồ mình sẽ tạo. Các sơ đồ sẽ tạo thành một mô hình sơ bộ về hệ mặt trời của chúng ta. Vì tôi tập trung vào công cụ chứ không phải vào UML, nên tôi sẽ giữ cho các sơ đồ đơn giản. Vì hệ mặt trời cụ thể của chúng ta là một trường hợp của hệ hành tinh nên bạn sẽ bắt đầu bằng mô hình lớp của hệ hành tinh như thể hiện ở Hình B.1. Hình B.2 là biểu đồ đối tượng của Trái đất và mặt trời. Nếu bạn muốn, bạn có thể điền vào các hành tinh còn lại.
