Data Modeling Made Simple will provide the business or IT professional with a practical working knowledge of data modeling concepts and best practices. This book is written in a conversational style that encourages you to read it from start to finish and master these ten objectives: Know when a data model is needed and which type of data model is most effective for each situation Read a data model of any size and complexity with the same confidence as reading a book Build a fully normalized relational data model, as well as an easily navigatable dimensional model Apply techniques to turn a logical data model into an efficient physical design Leverage several templates to make requirements gathering more efficient and accurate Explain all ten categories of the Data Model Scorecard Learn strategies to improve your working relationships with others Appreciate the impact unstructured data has, and will have, on our data modeling deliverables Learn basic UML concepts Put data modeling in context with XML, metadata, and agile development Book Review by Johnny Gay In this book review, I address each section in the book and provide what I found most valuable as a data modeler. I compare, as I go, how the book's structure eases the new data modeler into the subject much like an instructor might ease a beginning swimmer into the pool. This book begins like a Dan Brown novel. It even starts out with the protagonist, our favorite data modeler, lost on a dark road somewhere in France. In this case, what saves him isn't a cipher, but of all things, something that's very much like a data model in the form of a map! The author deems they are both way-finding tools. The chapters in the book are divided into 5 sections. The chapters in each section end with an exercise and a list of the key points covered to reinforce what you've learned. I find myself comparing the teaching structure of the book to the way most of us learn to swim.

This new book aims to provide both beginners and experts with a completely algorithmic approach to data analysis and conceptual modeling, database design, implementation, and tuning, starting from vague and incomplete customer requests and ending with IBM DB/2, Oracle, MySQL, MS SQL Server, or Access based software applications. A rich panoply of solutions to actual useful data sub-universes (e.g. business, university, public and home library, geography, history, etc.) is provided, constituting a powerful library of examples. Four data models are presented and used: the graphical Entity-Relationship, the mathematical EMDM, the physical Relational, and the logical deterministic deductive Datalog ones. For each one of them, best practice rules, algorithms, and the theory beneath are clearly separated. Four case studies, from a simple public library example, to a complex geographical study are fully presented, on all needed levels. Several dozens of real-life exercises are proposed, out of which at least one per chapter is completely solved. Both major historical and up-to-date references are provided for each of the four data models considered. The book provides a library of useful solutions to real-life problems and provides valuable knowledge on data analysis and modeling, database design, implementation, and fine tuning.

An introduction to the modeling of business information systems, with processes formally modeled using Petri nets. This comprehensive introduction to modeling business-information systems focuses on business processes. It describes and demonstrates the formal modeling of processes in terms of Petri nets, using a well-established theory for capturing and analyzing models with concurrency. The precise semantics of this formal method offers a distinct advantage for modeling processes over the industrial modeling languages found in other books on the subject. Moreover, the simplicity and expressiveness of the Petri nets concept make it an ideal language for explaining foundational concepts and constructing exercises. After an overview of business information systems, the book introduces the modeling of processes in terms of classical Petri nets. This is then extended with data, time, and hierarchy to model all aspects of a process. Finally, the book explores analysis of Petri net models to detect design flaws and errors in the design process. The text, accessible to a broad audience of professionals and students, keeps technicalities to a minimum and offers numerous examples to illustrate the concepts covered. Exercises at different levels of difficulty make the book ideal for independent study or classroom use.

أيهما أشد خطراً، المسدس أم حوض السباحة؟ ما هي الأشياء المشتركة بين معلمي المدارس ومصارعي السومو؟ لماذا ما يزال تجار المخدرات يعيشون مع أمهاتهم؟ ما هو مقدار اهتمام الوالدين حقاً؟ ما هو تأثير قضية «رو» و«ويد» في جرائم العنف؟ قد لا تبدو هذه الأسئلة مثل الأسئلة النمطية التي يسألها الاقتصادي، لكن ستيفن د. ليفيت ليس اقتصادياً نمطياً؛ إنه عالم شجاع أكثر من أي شيء آخر، يدرس المادة والأحاجي في الحياة اليومية ــ من الغش والجريمة إلى الرياضة وتربية الأطفال ــ وتقوم استنتاجاته عادة على قلب الحكمة التقليدية رأساً على عقب. وغالباً ما يبدأ بتل كبير من المعطيات وبسؤال بسيط لم يطرح من قبل. إنه يهتم ببعض هذه الأسئلة مثل قضايا الحياة والموت، وبعضها الآخر ذو ميزات استثنائية دون شك. وهكذا يحتوي هذا الكتاب على حقل جديد من الدراسة، وهو (الاقتصاد العجيب). ومن خلال سرده للقصص الآسرة ومن النظرة العميقة غير المباشرة، يبين ليفيت وزميله ستيفن ج. دوبنر أن الاقتصاد -في جذوره- دراسة للحوافز ـــ كيف يحصل الناس على ما يريدون أو يحتاجون، لاسيما عندما يريد الناس الآخرون الشيء ذاته أو يحتاجونه. في كتابهما (الاقتصاد العجيب)، يشرع المؤلفان في استكشاف الجانب الخفي ـــ من كل شيء؛ الأعمال الداخلية لعصابة مخدرات، وحقيقة الوسطاء العقاريين، وأساطير تمويل الحملات. وقصص الغش لدى معلمي المدارس. وأسرار جمعية كوكلوكس كلان (العرقية). ومن هنا فإذا كانت الأخلاق تمثل كيف نريد للعالم أن يسير، فإن الاقتصاد يمثل كيف يعمل العالم فعلاً. صحيح إن قراء هذا الكتاب سيتسلحون بقصص وأحاجٍ تكفي لتروى في آلاف الحفلات، لكن كتاب (الاقتصاد العجيب) يستطيع أن يقدم أكثر من ذلك، إنه يعيد تعريف الطريقة التي ننظر بها إلى العالم الحديث تعريفاً حرفياً. العبيكان للنشر

ظل يُقال لنا طيلة عشرات السنوات إن التفكير الإيجابي هو المفتاح إلى حياة سعيدة ثرية. لكن مارك مانسون يشتم تلك " الإيجابية " ويقول: " فلنكن صادقين، السيء سيء وعلينا أن نتعايش مع هذا ". لا يتهرّب مانسون من الحقائق ولا يغفلها بالسكّر، بل يقولها لنا كما هي: جرعة من الحقيقة الفجِّة الصادقة المنعشة هي ما ينقصنا اليوم. هذا الكتاب ترياق للذهنية التي نهدهد أنفسنا بها، ذهنية " فلنعمل على أن يكون لدينا كلنا شعور طيب " التي غزت المجتمع المعاصر فأفسدت جيلًا بأسره صار ينال ميداليات ذهبية لمجرد الحضور إلى المدرسة. ينصحنا مانسون بأن نعرف حدود إمكاناتنا وأن نتقبلها. وأن ندرك مخاوفنا ونواقصنا وما لسنا واثقين منه، وأن نكفّ عن التهرب والفرار من ذلك كله ونبدأ مواجهة الحقائق الموجعة، حتى نصير قادرين على العثور على ما نبحث عنه من جرأة ومثابرة وصدق ومسؤولية وتسامح وحب للمعرفة. لا يستطيع كل شخص أن يكون متميزًا متفوقًا. ففي المجتمع ناجحين وفاشلين؛ وقسم من هذا الواقع ليس عادلًا وليس نتيجة غلطتك أنت. وصحيح أن المال شيء حسن، لكن اهتمامك بما تفعله بحياتك أحسن كثيرًا؛ فالتجربة هي الثروة الحقيقية. إنها لحظة حديث حقيقي صادق لشخص يمسكك من كتفيك وينظر في عينيك. هذا الكتاب صفعة " منعشة لهذا الجيل حتى تساعده في عيش حياة راضية مستقرة.
