The third stage in designing a database is when we analyze our tables more closely and create a ___________ between tables.
Explanation
In the third stage of designing a database, we analyze our tables more closely and create a relationship between tables. This means that we establish a connection or association between different tables in the database. By creating relationships, we can define how the data in one table is related to the data in another table. This allows us to efficiently organize and retrieve information from the database, ensuring data integrity and avoiding redundancy.
2.
In a database table, the category of information is called ____________.
Explanation
In a database table, the category of information is called a field. A field represents a specific piece of data that is stored in a table. It is used to define the type of data that can be stored in a particular column of the table. Each field typically has a name and a data type associated with it, which determines the kind of information that can be stored in that field. Fields are essential for organizing and categorizing data within a database table.
3.
Computerized database is __________; since records stored in filing cabinets can be stored in just a single floppy disk.
Explanation
A computerized database is considered compact because it can store a large number of records in a very small space, such as a single floppy disk. This is in contrast to storing records in filing cabinets, which would require a significant amount of physical space. The compact nature of a computerized database allows for efficient storage and retrieval of information.
4.
Data definition is the stage when one gathers and list all necessary ___________ for our database.
Explanation
In the data definition stage, one collects and lists all the necessary fields for the database. Fields are the individual pieces of information that will be stored in the database, such as name, age, address, etc. By identifying and defining the fields, we are determining the specific data that will be stored and organized in the database. This step is crucial in creating a well-structured and functional database.
5.
In creating an effective database management system, careful _____________ is crucial.
Explanation
In creating an effective database management system, careful planning is crucial. Planning allows for the organization and structuring of the database, ensuring that it meets the needs and requirements of the users. It involves determining the goals and objectives of the system, identifying the data that needs to be stored, and designing the overall structure and layout. Without proper planning, the database may lack coherence, efficiency, and may not effectively serve its intended purpose. Therefore, planning is essential in creating an effective database management system.
6.
This key uniquely identifies each record in table.
Correct Answer
A. Primary key
Explanation
A primary key is a field or combination of fields in a database table that uniquely identifies each record in the table. It ensures that there are no duplicate records and allows for efficient retrieval and manipulation of data.
7.
It is an association established between common fields (columns) in two tables.
Correct Answer
B. Relationship
Explanation
A relationship is a connection or association between common fields (columns) in two tables. It allows for the linking of related data between the tables, enabling the retrieval and manipulation of information from multiple tables simultaneously. By establishing relationships, data can be efficiently organized and accessed, ensuring data integrity and reducing redundancy.
8.
It is stage where we break down some fields to more specific fields so we can store information in the smallest logical parts.
Correct Answer
B. Data refinement
Explanation
Data refinement is the correct answer because it refers to the process of breaking down larger fields into smaller, more specific fields. This allows for the storage of information in the smallest logical parts, making it easier to manage and analyze the data. The other options, such as data definition and establishing relationships, do not directly relate to this process of breaking down fields.
9.
This is the stage in database design where one gathers and list all the necessary fields for the database project.
Correct Answer
A. Data definition
Explanation
The stage in database design where one gathers and lists all the necessary fields for the database project is called data definition. This involves identifying and specifying the data elements or attributes that need to be stored in the database. Data refinement refers to the process of improving the quality and structure of the data. Establishing relationships involves defining the connections or associations between different data entities in the database. None of the above options accurately describe the stage of gathering and listing necessary fields.
10.
A column in a table is called a _________________.
Correct Answer
C. Field
Explanation
A column in a table is called a field. In a database, a field represents a specific piece of information within a record. Each field is assigned a specific data type, such as text, number, or date, and holds a value that corresponds to the type. Fields are used to organize and categorize data within a table, allowing for efficient storage and retrieval of information.
11.
It refers to row in a database table.
Correct Answer
A. Record
Explanation
A record refers to a row in a database table. In a database, information is organized into tables, and each table consists of rows and columns. Each row represents a record, which contains a set of related data. Therefore, the correct answer is "record" because it accurately describes a row in a database table.
12.
It is a type of database where one or more tables are connected to other tables in the database, such as in the library system .
Correct Answer
A. Relational database
Explanation
A relational database is a type of database that uses tables to store and organize data. In this type of database, tables are connected to each other through relationships, such as in the library system where tables for books, authors, and borrowers may be connected. This allows for efficient storage and retrieval of data, as well as the ability to perform complex queries and analysis on the data.
13.
What do you call the database that works with one set of database records at a time, such as the list of products in a Microsoft Excel file?
Correct Answer
C. Flat file database
Explanation
A flat file database is the correct answer because it is a type of database that works with one set of database records at a time, such as the list of products in a Microsoft Excel file. Unlike a relational database, which allows for relationships between multiple sets of data, a flat file database is a simple, single-file database that stores all information in a single table. It is commonly used for small-scale applications or when the data does not need to be linked or manipulated in complex ways.
14.
It stands for POS in a checkout counter.
Correct Answer
C. Point-of-Sales
Explanation
"POS" stands for "Point-of-Sales." It refers to the location or system where a retail transaction is completed. At the POS, a customer makes payment for goods or services they have received. The POS system typically includes hardware like a cash register or terminal and software that processes transactions, manages inventory, and generates receipts. It's a critical point in retail operations where sales are finalized, making it essential for businesses to efficiently manage and track transactions.
15.
It is a collection of data that is related to a particular subject or purpose.
Correct Answer
A. Database
Explanation
A database is a collection of data that is organized and stored in a structured manner, allowing for efficient retrieval, manipulation, and management. It is designed to hold information related to a specific subject or purpose, such as customer records, inventory data, or financial transactions. A database provides a centralized and coherent storage solution, enabling users to easily access and analyze the data it contains.
