Learn SQLite with Python
This book is SQLite-based python programming for database-driven desktop projects. Deliberately designed for various levels of programming skill, this book is suitable for students, engineers, and even researchers in various disciplines. There is no need for advanced programming experience, and school-level programming skills are needed. In the first chapter, you will learn to use several widgets in PyQt5: Display a welcome message; Use the Radio Button widget; Grouping radio buttons; Displays options in the form of a check box; and Display two groups of check boxes. In chapter two, you will learn to use the following topics: Using Signal / Slot Editor; Copy and place text from one Line Edit widget to another; Convert data types and make a simple calculator; Use the Spin Box widget; Use scrollbars and sliders; Using the Widget List; Select a number of list items from one Widget List and display them on another Widget List widget; Add items to the Widget List; Perform operations on the Widget List; Use the Combo Box widget; Displays data selected by the user from the Calendar Widget; Creating a hotel reservation application; and Display tabular data using Table Widgets. In chapter three, you will learn: How to create the initial three tables project in the School database: Teacher, Class, and Subject tables; How to create database configuration files; How to create a Python GUI for inserting and editing tables; How to create a Python GUI to join and query the three tables. In chapter four, you will learn how to: Create a main form to connect all forms; Create a project will add three more tables to the school database: Student, Parent, and Tuition tables; Create a Python GUI for inserting and editing tables; Create a Python GUI to join and query over the three tables. In chapter five, you will join the six classes, Teacher, TClass, Subject, Student, Parent, and Tuition and make queries over those tables. In chapter six, you will create dan configure database. In this chapter, you will create Suspect table in crime database. This table has eleven columns: suspect_id (primary key), suspect_name, birth_date, case_date, report_date, suspect_ status, arrest_date, mother_name, address, telephone, and photo. You will also create GUI to display, edit, insert, and delete for this table. In chapter seven, you will create a table with the name Feature_Extraction, which has eight columns: feature_id (primary key), suspect_id (foreign key), feature1, feature2, feature3, feature4, feature5, and feature6. The six fields (except keys) will have VARBINARY(MAX) data type. You will also create GUI to display, edit, insert, and delete for this table. In chapter eight, you will create two tables, Police and Investigator. The Police table has six columns: police_id (primary key), province, city, address, telephone, and photo. The Investigator table has eight columns: investigator_id (primary key), investigator_name, rank, birth_date, gender, address, telephone, and photo. You will also create GUI to display, edit, insert, and delete for both tables. In the last chapter, you will create two tables, Victim and Case_File. The Victim table has nine columns: victim_id (primary key), victim_name, crime_type, birth_date, crime_date, gender, address, telephone, and photo. The Case_File table has seven columns: case_file_id (primary key), suspect_id (foreign key), police_id (foreign key), investigator_id (foreign key), victim_id (foreign key), status, and description. You will create GUI to display, edit, insert, and delete for both tables as well.
Learn SQLite with JDBC
In this book, you will learn how to build from scratch a criminal records management database system using Java / SQLite. All Java code for digital image processing in this book is Native Java. Intentionally not to rely on external libraries, so that readers know in detail the process of extracting digital images from scratch in Java. In the first chapter, you will be shown how to create SQLite database and tables with Java. In second chapter, you will be taught how to extract image features, utilizing BufferedImage class, in Java GUI. Digital image techniques to extract image features used in this chapted are grascaling, sharpening, invertering, blurring, dilation, erosion, closing, opening, vertical prewitt, horizontal prewitt, Laplacian, horizontal sobel, and vertical sobel. For readers, you can develop it to store other advanced image features based on descriptors such as SIFT and others for developing descriptor based matching. In the third chapter, you will be taught to create Java GUI to view, edit, insert, and delete Suspect table data. This table has eleven columns: suspect_id (primary key), suspect_name, birth_date, case_date, report_date, suspect_ status, arrest_date, mother_name, address, telephone, and photo. In the fourth chapter, you will be taught to create Java GUI to view, edit, insert, and delete Feature_Extraction table data. This table has eight columns: feature_id (primary key), suspect_id (foreign key), feature1, feature2, feature3, feature4, feature5, and feature6. All six fields (except keys) will have a BLOB data type, so that the image of the feature will be directly saved into this table. In the fifth chapter, you will add two tables: Police_Station and Investigator. These two tables will later be joined to Suspect table through another table, File_Case, which will be built in the seventh chapter. The Police_Station has six columns: police_station_id (primary key), location, city, province, telephone, and photo. The Investigator has eight columns: investigator_id (primary key), investigator_name, rank, birth_date, gender, address, telephone, and photo. Here, you will design a Java GUI to display, edit, fill, and delete data in both tables. In the sixth chapter, you will add two tables: Victim and Case_File. The File_Case table will connect four other tables: Suspect, Police_Station, Investigator and Victim. The Victim table has nine columns: victim_id (primary key), victim_name, crime_type, birth_date, crime_date, gender, address, telephone, and photo. The Case_File has seven columns: case_file_id (primary key), suspect_id (foreign key), police_station_id (foreign key), investigator_id (foreign key), victim_id (foreign key), status, and description. Here, you will also design a Java GUI to display, edit, fill, and delete data in both tables. Finally, this book is hopefully useful for you.
MAHIR Visual C# Dengan Membuat Animasi dan Game
Pada bab pertama, Anda akan belajar bagaimana membangun aplikasi Visual C# dan bagaimana lingkungan pengembangan (IDE, integrated development environment) Visual C# digunakan untuk mengembangkan sebuah aplikasi game sederhana. Pada bab kedua, Anda akan membangun sebuah projek agar anak-anak (orang dewasa) dapat berlatih keterampilan dasar dalam operasi penjumlahan, pengurangan, perkalian, dan pembagian. Projek Game Matematika ini dapat dipakai untuk memilih jenis soal dan apa faktor yang ingin digunakan. Projek ini memiliki tiga opsi pewaktuan. Soal-soal matematika acak menggunakan nilai dari 0 sampai 9 akan disajikan. Opsi-opsi pewaktuan disediakan untuk mengukur akurasi dan kecepatan. Pada bab ketiga, Anda akan membangun sebuah program Ujian Pilihan Berganda. Item-item acak yang diekstraksi dari sebuah file akan ditampilkan pada user. User kemudian memilih item yang cocok. Sebagai contoh, jika sebuah ibukota ditampilkan, maka user akan memilih propinsi yang bersangkutan. Jawaban disajikan dalam pilihan berganda atau diketikkan sendiri oleh user. Pada bab keempat, Anda akan membangun sebuah program game kartu BlackJack. Program ini dapat dipakai oleh seorang pemain untuk melawan bandar komputer. Ide BlackJack adalah untuk mendapatkan skor lebih tinggi dari bandar tanpa melewati poin 21. Kartu-kartu dihitung sesuai nilainya (kecuali kartu Jack, Queen, dan King bernilai 10 dan Ace bernilai satu atau sebelas sesuai keinginan Anda). Jika Anda mengalahkan bandar, Anda mendapatkan 10 poin. Jika Anda mendapatkan BlackJack (nilai 21 hanya dengan dua kartu) dan mengalahkan bandar, Anda mendapatkan 15 poin. Jika bandar mengalahkan Anda, Anda kehilangan 10 poin. Semoga buku ini bermanfaat bagi mereka yang berminat memperdalam pemrograman C#. NET.
