Providing variables in prompts is crucial for creating flexible, reusable, and contextually accurate prompts. Here are best practices for integrating variables into prompts, along with examples: --- ### **1. Use Descriptive Variable Names** - Ensure variable names clearly describe their purpose or content. - Avoid ambiguous or generic names. **Example**: ```plaintext "Generate a summary of the article titled '{article_title}' published on {publish_date}." ``` --- ### **2. Use Placeholders for Variables** - Represent variables as placeholders (e.g., `{variable_name}`, `[variable_name]`, or ``). - Clearly distinguish placeholders from static text. **Example**: ```plaintext "Provide a detailed report about [product_name] including its features, price, and customer feedback." ``` --- ### **3. Define Default Values for Optional Variables** - Assign default values for variables that may not always be provided to avoid incomplete prompts. **Example**: ```plaintext "Translate the text '{text_to_translate}' into {target_language:English}." ``` (Default value: English) --- ### **4. Specify Input Types for Variables** - Indicate the expected type of input (e.g., string, number, date). - This ensures the variables are correctly formatted and meaningful. **Example**: ```plaintext "Calculate the monthly payment for a loan of {loan_amount:float} at an interest rate of {interest_rate:float}% over {loan_term:int} months." ``` --- ### **5. Use Context-Specific Variables** - Tailor variables to the domain or application context for clarity and relevance. **Example (E-commerce)**: ```plaintext "List the top 5 best-selling products in the {category_name} category for the month of {month}." ``` --- ### **6. Provide Context for Variables** - Include additional details in the prompt to clarify how the variable should be used. **Example**: ```plaintext "Create a marketing tagline for a product named '{product_name}', which is aimed at {target_audience}, and emphasizes {key_feature}." ``` --- ### **7. Avoid Overloading Prompts with Variables** - Use only the variables necessary to achieve the task. - Avoid overly complex or crowded prompts. **Example (Simple)**: ```plaintext "Write a short description for the item '{item_name}'." ``` **Example (Complex - Avoid):** ```plaintext "Describe the item '{item_name}' with features '{feature_1}', '{feature_2}', and '{feature_3}' for the audience '{audience}', considering the context '{context}'." ``` --- ### **8. Validate and Sanitize Variables** - Ensure that variables are properly validated and sanitized before inclusion in the prompt to prevent malicious inputs or errors. **Example**: ```plaintext "Generate a travel itinerary for the city '{city_name}' for {number_of_days:int} days." ``` --- ### **9. Use Variables in Structured Formats** - For structured outputs, include variables as keys to guide the format. **Example (JSON-like Prompt)**: ```plaintext "Provide a JSON output for the employee details:/n{/n 'name': '{employee_name}',/n 'age': {employee_age:int},/n 'position': '{job_title}'/n}" ``` --- ### **10. Test Prompts with Multiple Variable Scenarios** - Ensure prompts work with all possible variable combinations, including edge cases (e.g., empty or default values). **Example**: ```plaintext "Generate a weather update for {city_name}. If {city_name} is not provided, use 'New York'." ``` --- ### **Advanced Examples** 1. **Personalized Assistance:** ```plaintext "Schedule a meeting for {user_name} with {meeting_subject} on {meeting_date} at {meeting_time}." ``` 2. **Dynamic Filtering:** ```plaintext "Retrieve a list of all employees in the department '{department_name}' hired after {hire_date:YYYY-MM-DD}." ``` 3. **Creative Writing:** ```plaintext "Write a story set in {location}, featuring a character named {character_name} who is on a mission to {mission}." ``` 4. **Data Retrieval:** ```plaintext "Find the {metric_name} for {company_name} from {start_date} to {end_date} and display it in a table." ``` --- By following these best practices, you can make prompts more robust, easier to manage, and adaptable to diverse use cases.

Data Product Approach

Why Build Data Products

Companies should build data products because they transform raw data into actionable, reusable assets that directly drive business outcomes. Instead of treating data as a byproduct of operations, a data product approach emphasizes usability, governance, and value creation. Ultimately, they turn data from a cost center into a growth engine, unlocking compounding value across every function of the enterprise.
