data base management system
This document discusses entity-relationship (ER) diagrams and database modeling. It defines key concepts like entities, attributes, and relationships. An entity represents a person, place, or object of interest. Attributes are properties of entities like name and address. Relationships show how entities are connected. The document provides examples of an ER diagram for a basketball game with entities like teams, players, and games. It also explains different relationship types like one-to-one, one-to-many, and many-to-many.

Entity relationship diagram
In software engineering, an entity–relationship model (ER model) is a data model for describing the data or information aspects of a business domain or its process requirements
Database design
1. The document discusses database design and normalization. It provides examples of product, order, and store tables.
2. The tables are normalized to first normal form by extracting repeating groups into separate tables and ensuring each cell contains a single value.
3. Primary keys are assigned to uniquely identify each record in tables. Foreign keys are also included to link related data across tables.
Business Computer Project 4
The document discusses database design concepts including entities, attributes, and relationships. It explains that entities can have a one-to-one, one-to-many, or many-to-many relationship. A one-to-one relationship means each record in one entity is linked to one and only one record in the other entity. An example given is a relationship between an order and its shipping details, where each order would have a single set of shipping details.
Object-Oriented Programming 10
This document discusses GUI and event handling in Java. It begins by introducing GUI components like frames, panels, buttons, labels, text fields, lists, scroll panes, checkboxes, comboboxes and menus. It then covers various layout managers including flow, border, grid and gridbag layouts. Finally, it discusses event handling in Java by adding event listeners to components to trigger actions when events like button clicks occur.
Object-Oriented Programming 9
The document discusses exception handling in Chapter 9. It introduces different types of errors like syntax errors and logical errors. It then defines exceptions and different types of exceptions like RuntimeException, ArrayIndexOutOfBoundsException, and ArithmeticException. The document explains different IOExceptions and how to use try, catch, and finally blocks to handle exceptions in Java code.
Object-Oriented Programming 8
This document discusses abstract classes, interfaces, and multiple inheritance in Java. It includes definitions and examples of abstract classes and methods, how abstract classes can be extended, and how interfaces define abstract methods that implementing classes must implement. It notes that abstract classes can include both abstract and concrete methods while interfaces only contain abstract methods. The document also explains that Java supports multiple inheritance through interfaces, allowing classes to implement multiple interfaces, but not extend multiple classes.
Object-Oriented Programming 7
This document discusses inheritance and encapsulation in chapter 7. It explains key concepts of inheritance including subclasses inheriting from superclasses. Methods can be overridden in subclasses. The final keyword is used to prevent overriding of methods. The document also covers encapsulation, which involves restricting access to members and hiding implementation details in an object.
Object-Oriented Programming 6
This document discusses different types of methods in programming including instance methods, static methods, constructor methods, overloading methods, and overriding methods. It was written by Mr. Warawut Khangkhan and provides his contact information including an email address and social media profile. The document contains 4 pages or sections about methods.
Management Information System 6
The document discusses different types of data communication and telecommunication technologies. It describes data transmission and various components involved, including sender, receiver, messages, and communication protocols. It then covers different communication mediums such as twisted-pair cable, coaxial cable, fiber-optic cable, microwave transmission, satellite, infrared, radio, and cellular networks. Specific details are provided on the bandwidth and characteristics of each technology type.
Management Information System 5
The document discusses database systems and database management systems (DBMS). It describes the key components of a DBMS, including the data repository that stores data, the data dictionary that contains metadata, and the DBMS software. It also explains the three levels of schema in a database system - the external level visible to users, the conceptual level that defines the structure, and the internal level that defines how data is stored physically.
Management Information System 4
This chapter discusses different types of computer software, including system software like operating systems and utility programs, as well as application software for general use or specific tasks. It describes programming languages from early machine code to modern languages like JavaScript and Python. Open source software and licensing models are also covered.
Object-Oriented Programming 5
This document discusses arrays and strings in Java. It covers one-dimensional and two-dimensional arrays, ArrayLists, methods for arrays like sort() and binarySearch(), and enum types. For strings, it explains string methods such as equals(), compareTo(), concat(), substring(), replace(), toUpperCase(), and indexOf(). It also covers StringBuffers and StringBuilders.
Business Computer Project 3
The document discusses AJAX and XML. It defines AJAX as Asynchronous JavaScript and XML, which allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes. It also defines XML as a markup language that is commonly used to transport data in AJAX applications. Finally, it discusses how the XMLHttpRequest object allows JavaScript code in a web page to communicate with web servers to request and receive back data without interfering with the display and behavior of the existing page.
Management Information System 3
1) The document discusses different types of computer hardware, including supercomputers, mainframe computers, minicomputers, and microcomputers.
2) It describes the central processing unit (CPU) and its main components: the control unit, arithmetic/logical unit, and memory unit.
3) The document outlines different types of computer memory, including ROM, RAM, SDRAM, and DDR SDRAM.
