The correct answer is: C. Schema<\/strong><\/p>\n A schema is a description of the structure of a database. It defines the tables, columns, and relationships between the data in the database. A schema is used to create a database and to define the data that can be stored in the database.<\/p>\n A module is a self-contained unit of code that can be reused in multiple applications. A module is typically used to encapsulate a set of related functions or data.<\/p>\n A relational model is a way of representing data in a database. In a relational model, data is stored in tables, and each table has a set of columns and rows. The columns represent the attributes of the data, and the rows represent the instances of the data.<\/p>\n A sub-schema is a subset of a schema. A sub-schema is used to define a view of the data in a database for a particular application.<\/p>\n In conclusion, the way a particular application views the data from the database that the application uses is a schema.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Module” option2=”Relational model” option3=”Schema” option4=”Sub-schema” correct=”option3″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[672],"tags":[],"class_list":["post-15747","post","type-post","status-publish","format-standard","hentry","category-ms-access","no-featured-image-padding"],"yoast_head":"\n
