ICT - Database Questions

A database is a collection of data or information that is stored in a logical and structured way. It allows for efficient storage, retrieval, and manipulation of data, making it easier to organize and manage large amounts of information. Databases are commonly used in various applications and industries, such as business, finance, healthcare, and education, to store and manage data effectively.

Tables can contain many records, and records run in rows. In a table, each row represents a single record, and multiple rows make up the entire set of records in the table. Therefore, the correct answer is "rows."

In a database, data or information is stored in tables. Tables are structured collections of related data organized into rows and columns. Each row represents a record or instance of data, while each column represents a specific attribute or characteristic of the data. Tables provide a systematic way to store, organize, and retrieve data, allowing for efficient data management and analysis.

A field is a single piece of information that is stored about a thing or person. It can be a specific attribute or characteristic that describes the thing or person in question. Fields are commonly used in databases to organize and store data in a structured manner. Each field corresponds to a specific data type and holds a particular value related to the thing or person being stored.

A record in a database refers to all of the data about one person or item. It represents a complete set of information related to a specific entity in the database. This can include various fields and attributes that describe the characteristics and properties of the entity. Each record is unique and serves as a single unit of data within the database system.

The given answer, "Fields," is correct because all the listed items (First name, Last name, Date of Birth, Height, Eye color, and Address) are types of data that can be stored in separate fields within a database or spreadsheet. Fields are used to categorize and organize data, making it easier to search, sort, and analyze.

Paper-based databases have several advantages. Firstly, they are portable, meaning they can be easily carried and accessed anywhere. Secondly, they generally do not require special training, as most people are familiar with using paper and writing. Additionally, paper-based databases can still function during a powercut, unlike electronic databases that rely on electricity. However, the statement "They can be updated easily" is not mentioned in the given options.

Paper-based databases have several disadvantages. Firstly, they can be easily lost or damaged, leading to the loss of valuable data. Secondly, updating or copying information in a paper database is a time-consuming and cumbersome process. Additionally, keeping paper databases up to date can be expensive as it requires constant printing and manual entry of data. Lastly, paper databases require a significant amount of physical space for storage, which can be costly and inefficient.
