Part III: Write short answers to the following questions.<br /><br />1. What is a database?<br />A database is a collection of organized data that is stored and managed in a computer system. It allows for efficient storage, retrieval, and manipulation of data.<br /><br />2. What are the basic elements of ERD?<br />The basic elements of an Entity-Relationship Diagram (ERD) are entities, attributes, and relationships. Entities represent real-world objects or concepts, attributes describe the characteristics of entities, and relationships show how entities are connected to one another.<br /><br />3. What is a relational data model?<br />A relational data model is a type of database model in which data is stored in tables, and each table consists of rows and columns. The rows represent individual records, and the columns represent the attributes of the records. The relationships between tables are established through the use of keys.<br /><br />4. What is a one-to-many relationship? Give examples.<br />A one-to-many relationship is a type of relationship between two entities in which one entity can be associated with multiple instances of another entity. For example, a customer can place multiple orders, so the relationship between customers and orders is one-to-many. Another example is a teacher can teach multiple classes, so the relationship between teachers and classes is one-to-many.<br /><br />5. What is the use of table object in Microsoft Access?<br />The table object in Microsoft Access is used to store and organize data. It is the fundamental building block of a database, and it allows for the storage of multiple records, each with its own set of attributes. Tables can be used to store information about entities such as customers, products, or orders.<br /><br />6. What is the use of query in Microsoft Access?<br />A query in Microsoft Access is a tool used to retrieve specific data from one or more tables. Queries allow users to filter, sort, and manipulate data based on specific criteria. They can be used to generate reports, perform data analysis, and answer specific questions about the data.<br /><br />Part IV: Discussion questions<br /><br />1.
