Plotly<\/strong> inside a notebook cell.<\/li>\n<\/ul>\n\n\n\nHands-On Data Analysis with Databricks<\/h2>\n\n\n\n The best way to understand Databricks for data analysis is to work through a small dataset. In this example, we will analyze a retail sales dataset to find sales trends, identify the best-performing products, and understand customer behavior.<\/p>\n\n\n\n
Databricks notebooks let you combine Python, PySpark, SQL, and visualizations in the same workspace, making them useful for exploratory data analysis and larger datasets.<\/p>\n\n\n\n
Step 1: Create a Databricks Notebook<\/h3>\n\n\n\n Create a new notebook in your Databricks workspace and select Python<\/strong> as the default language.<\/p>\n\n\n\nYou can either upload your own CSV dataset or use a sample dataset available in Databricks.<\/p>\n\n\n\n
For this walkthrough, assume the dataset contains these columns:<\/p>\n\n\n\n
\norder_id<\/code><\/li>\n\n\n\norder_date<\/code><\/li>\n\n\n\nproduct<\/code><\/li>\n\n\n\ncategory<\/code><\/li>\n\n\n\nquantity<\/code><\/li>\n\n\n\nsales<\/code><\/li>\n\n\n\nregion<\/code><\/li>\n<\/ul>\n\n\n\nStep 2: Load the Dataset<\/h3>\n\n\n\n Once the CSV file is available in your Databricks environment, load it into a Spark DataFrame.<\/p>\n\n\n\n
df = spark.read.csv(\n \"\/path\/to\/sales.csv\",\n header=True,\n inferSchema=True\n)\n\ndisplay(df)<\/code><\/pre>\n\n\n\nThe display()<\/code> function helps you quickly inspect the data and view it in a tabular format.<\/p>\n\n\n\nStep 3: Understand the Data<\/h3>\n\n\n\n Before analyzing the data, check its structure and identify potential data-quality issues.<\/p>\n\n\n\n
df.printSchema()\ndf.describe().show()<\/code><\/pre>\n\n\n\nYou can also check the number of records:<\/p>\n\n\n\n
print(\"Total records:\", df.count())<\/code><\/pre>\n\n\n\nAt this stage, look for:<\/p>\n\n\n\n
\nMissing values<\/li>\n\n\n\n Incorrect data types<\/li>\n\n\n\n Duplicate records<\/li>\n\n\n\n Unusual sales values<\/li>\n\n\n\n Incorrect dates<\/li>\n<\/ul>\n\n\n\nStep 4: Clean the Data<\/h3>\n\n\n\n Remove duplicate orders and rows where important values are missing.<\/p>\n\n\n\n
df = df.dropDuplicates([\"order_id\"])\n\ndf = df.dropna(\n subset=[\"order_date\", \"product\", \"quantity\", \"sales\"]\n)<\/code><\/pre>\n\n\n\nConvert the order date into a proper date format if necessary:<\/p>\n\n\n\n
from pyspark.sql.functions import to_date\n\ndf = df.withColumn(\n \"order_date\",\n to_date(\"order_date\")\n)<\/code><\/pre>\n\n\n\nCleaning the data before analysis helps prevent inaccurate results.<\/p>\n\n\n\n
Step 5: Find Total Sales<\/h3>\n\n\n\n Now calculate the total sales generated by the business.<\/p>\n\n\n\n
from pyspark.sql.functions import sum\n\ntotal_sales = df.select(\n sum(\"sales\").alias(\"total_sales\")\n)\n\ndisplay(total_sales)<\/code><\/pre>\n\n\n\nThis gives you a basic business metric that can be used as a starting point for further analysis.<\/p>\n\n\n\n
Step 6: Analyze Sales by Category<\/h3>\n\n\n\n You can use PySpark to identify which product categories generate the most revenue.<\/p>\n\n\n\n
from pyspark.sql.functions import sum\n\ncategory_sales = (\n df.groupBy(\"category\")\n .agg(sum(\"sales\").alias(\"total_sales\"))\n .orderBy(\"total_sales\", ascending=False)\n)\n\ndisplay(category_sales)<\/code><\/pre>\n\n\n\nThe resulting table can help you identify the strongest and weakest product categories.<\/p>\n\n\n\n
Step 7: Analyze Regional Performance<\/h3>\n\n\n\n You can also compare sales across different regions.<\/p>\n\n\n\n
region_sales = (\n df.groupBy(\"region\")\n .agg(sum(\"sales\").alias(\"total_sales\"))\n .orderBy(\"total_sales\", ascending=False)\n)\n\ndisplay(region_sales)<\/code><\/pre>\n\n\n\nThis can answer questions such as:<\/p>\n\n\n\n
\nWhich region generates the most revenue?<\/li>\n\n\n\n Which regions need improvement?<\/li>\n\n\n\n Are sales concentrated in a particular location?<\/li>\n<\/ul>\n\n\n\nStep 8: Analyze Monthly Trends<\/h3>\n\n\n\n To understand how sales change over time, extract the month from the order date.<\/p>\n\n\n\n
from pyspark.sql.functions import month, year\n\nmonthly_sales = (\n df.withColumn(\"year\", year(\"order_date\"))\n .withColumn(\"month\", month(\"order_date\"))\n .groupBy(\"year\", \"month\")\n .agg(sum(\"sales\").alias(\"total_sales\"))\n .orderBy(\"year\", \"month\")\n)\n\ndisplay(monthly_sales)<\/code><\/pre>\n\n\n\nYou can then create a line chart from the result using Databricks’ built-in visualization features. Databricks supports creating charts directly from notebook and SQL query results.<\/p>\n\n\n\n
Step 9: Use SQL for Analysis<\/h3>\n\n\n\n Databricks also allows analysts to work with SQL. For example:<\/p>\n\n\n\n
SELECT\n category,\n SUM(sales) AS total_sales\nFROM sales_data\nGROUP BY category\nORDER BY total_sales DESC;<\/code><\/pre>\n\n\n\nThis is particularly useful for data analysts who are already comfortable with SQL.<\/p>\n\n\n\n
Databricks SQL provides a SQL editor, dashboards, alerts, jobs, and other tools for querying and analyzing data.<\/p>\n\n\n\n
Step 10: Turn the Analysis into Insights<\/h3>\n\n\n\n The final step is not just creating charts. You should explain what the results mean.<\/p>\n\n\n\n
For example:<\/p>\n\n\n\n
\nElectronics generated the highest sales among all categories.<\/li>\n\n\n\n The South region contributed the lowest revenue.<\/li>\n\n\n\n Sales increased during the final quarter.<\/li>\n\n\n\n A small number of products contributed a large share of total revenue.<\/li>\n<\/ul>\n\n\n\nThis is where data analysis becomes useful for business decision-making.<\/p>\n\n\n\n
