CS 307 - Database Design and Management Quiz

A structured collection of data, organized and managed to share information effectively. Think of it as a digital filing system for all your information.

A structured way to represent data that defines relationships between different elements, like tables, columns, and rows. It's like a blueprint for your database.

A popular database model that organizes data into tables with rows and columns. It's like a spreadsheet but with powerful features for managing relationships between data.

A technique used to create a visual representation of the relationships between entities in a database. It's like a diagram showing how different things are connected.

A process of optimizing the design of database tables to reduce redundancy and improve efficiency by distributing information effectively. It's like organizing your house to avoid clutter and maximize space.

A powerful language used to interact with relational databases. It allows you to retrieve, insert, update, and delete data. Think of it as the language you use to communicate with a database.

A database system designed to manage large amounts of data distributed across multiple locations. It's like having multiple libraries connected and working together.

The ability for different users to access and modify data concurrently without causing issues. It's like managing a shared library book system ensuring everyone can access the books smoothly.

A collection of tools for storing, accessing, and managing organized information.

Data that is stored in a way that it's easily accessed, updated, and managed.

The concept of storing and managing information in a way that is consistent and efficient.

Separate applications can access and use the same data, reducing redundancy and promoting data consistency.

Databases are a vital part of computer science, with skills in their management being essential for CS graduates.

The focus is on understanding how databases work, designing database structures, and applying database management tools.

A combination of lectures, hands-on labs, and self-study helps to provide a comprehensive understanding of the subject.

The course evaluation is based on a combination of coursework and a final exam.

Data is information in a machine-readable format, like numbers, letters, or symbols, that computers can process. Imagine it as the raw ingredients for a recipe, waiting to be used to create a delicious dish.

A database is an organized collection of related data, designed for specific purposes. Think of it as a giant library where related information is categorized and easily accessible.

A database is a collection of related information that represents some aspect of the real world. It's like a mini-model of a specific area or aspect of the world.

Traditional file systems manage data in separate files within folders, like folders in a filing cabinet. It lacks the ability to connect and analyze information easily.

Data redundancy occurs in traditional file systems when the same information is stored in multiple locations, potentially leading to inconsistencies. It's like having different versions of the same document in multiple folders.

Data inconsistency occurs in traditional file systems when the same information has different values in separate locations, leading to confusion and errors. Imagine a database that says you live in two different cities.

Data can be redundant and inconsistent in traditional file systems because data is often duplicated and managed independently in various files. It's like having multiple copies of a recipe with different ingredients.

Traditional file systems had limitations like inflexibility in querying and reporting, limited security, and lack of concurrent access. Imagine a library where only one person can access a book at a time.

A software system used to manage, organize, and access data in a consistent and efficient way. It's like a librarian for your digital information, allowing you to store, retrieve, and update data easily.

The process of gathering, storing, retrieving, and manipulating data in a database. Imagine a library where you can add new books, keep them safe, find specific ones, and update details or remove books.

The ability of a database system to handle multiple users accessing and modifying data simultaneously without causing conflicts. Think of a busy library where people can borrow and return books without causing chaos.

Ensuring that the data remains intact and accessible even after hardware failures or software errors. It's like having a backup system for your library to ensure you don't lose any books in case of a disaster.

The capability of a database to protect data from unauthorized access, ensuring only authorized users can view or modify information. This ensures confidentiality and prevents tampering.

Ensuring that the data remains consistent and reliable over long periods, even when accessed by different applications. It's like having a library that keeps its books organized and accurate over time.
