Databases are primarily used to store and link data. They provide a structured way to organize and store large amounts of data, allowing for efficient retrieval and manipulation of information. Databases also enable the establishment of relationships between different sets of data, making it easier to analyze and extract meaningful insights. By storing and linking data, databases facilitate data management, data integration, and data sharing across various applications and systems.

In a spreadsheet, each box that holds data is referred to as a "cell". A cell is the basic unit of a spreadsheet and is identified by a unique combination of a column letter and a row number. It can hold different types of data such as numbers, text, or formulas. Cells are used to organize and manipulate data within a spreadsheet, allowing for calculations, data analysis, and presentation of information.

When creating a database, the computer program does not automatically detect the data type. The user needs to explicitly specify the type of data that will be stored in the database. This is because different data types require different storage mechanisms and operations. Therefore, it is necessary to inform the computer program about the data type to ensure proper handling and manipulation of the data within the database.

In Microsoft Excel, the "=" symbol is used to start a calculation. When you type "=" followed by a formula or function, Excel will evaluate the expression and provide the result. This symbol is essential for performing calculations in Excel and is the standard way to initiate any mathematical operation or formula in a cell.

Microsoft Access is the correct answer because it is a database management system that allows users to create, manage, and manipulate databases. It provides tools and features specifically designed for database creation and management, such as table design, data entry forms, queries, and reports. Microsoft Publisher, Microsoft Excel, Microsoft Word, and Microsoft PowerPoint are all office productivity programs that do not have the same database functionality as Microsoft Access.

Spreadsheets are primarily used to perform calculations. They are designed to handle numerical data and perform various mathematical operations, such as addition, subtraction, multiplication, and division. Spreadsheets also have built-in functions and formulas that can be used to perform more complex calculations, analyze data, and generate reports. They provide a grid-like structure that allows users to organize and manipulate data in a tabular format, making them an essential tool for financial analysis, budgeting, data analysis, and other numerical tasks.

Once your database is full of data, you can create a report using the database program. A report allows you to display and print the data in a structured and organized manner. Reports are commonly used to summarize and present data in a format that is easy to read and understand.

The data in a database is stored in a table. A table is a structured collection of data organized in rows and columns. Each row represents a record, and each column represents a field or attribute. Tables are used to store and organize large amounts of data in a structured and efficient manner, allowing for easy retrieval and manipulation of the data.

The given question asks for an option that is NOT an in-built function in Excel. Among the options provided, SUM, COUNT, COUNTIF, and AVERAGE are all in-built functions in Excel that perform mathematical calculations and data analysis. However, GRAPH is not an in-built function in Excel. Excel does provide various charting and graphing tools, but there is no specific function called GRAPH.

The use of the $ symbol in an equation tells Excel to lock the address of the cell it is looking at. This means that when the formula is copied or dragged to other cells, the cell reference with the $ symbol will not change. This is useful when you want to keep a specific cell reference constant in a formula while allowing other cell references to adjust relative to their new location.
