WGU C175 - Chapter 2: Data Modeling Latest 2022 Graded A+ 3 Vs (3 basic characteristics of Big Data databases) ✔✔Volume, velocity, and variety Abstract Data Type (ADT) ✔✔Data type that desc... ribes a set of similar objects with shared and encapsulated data representation and methods. An abstract data type is generally used to describe complex objects American National Standards Institute (ANSI) ✔✔The group that accepted the DBTG recommendation and augmented database standards in 1975 through its SPARC committee Application Programming Interface (API) ✔✔Software through which programmers interact with middleware. An API allows the use of generic SQL code, thereby allowing client processes to be database server-independent Attribute ✔✔A characteristic of an entity or object. An attribute has a name and a data type Balancing ✔✔Ensuring that the processing load is distributed evenly among multiple servers Big Data ✔✔A movement to find new and better ways to manage large amounts of web-generated data and derive business insight from it, while simultaneously providing high performance and scalability at a reasonable cost Class ✔✔A collection of similar objects with shared structure (attributes) and behavior (methods). A class encapsulates an object's data representation and a method's implementation. Classes are organized in a class hierarchy Class Diagram Notation ✔✔The set of symbols used in the creation of class diagrams in UML object modeling Class Diagrams ✔✔A diagram used to represent data and their relationships in UML object notation Class Hierarchy ✔✔The organization of classes in a hierarchical tree in which each parent class is a superclass and each child class is a subclass Client ✔✔Any process that requests specific services from server services processes in a client/server environment Client Node ✔✔One of three types of nodes used in the Hadoop Distributed File System (HDFS). The client node acts as the interface between user application and the HDFS. Complex Object ✔✔An object formed by several different objects in complex relationships Conceptual Model ✔✔The output of conceptual design process. Provides a global view of an entire database and describes the main data objects, avoiding details [Show More]
