Luma Module

Problem Statement
E-commerce data often becomes harder to read when reports require totals, counts, averages, and category-level views. Learners may understand how to filter records but feel unsure when asked to summarize order activity or compare groups of data. It can also be difficult to know when to use raw rows and when to create grouped results. Without a clear method, reports may include too much detail or miss the main point of the question.

Solution
Luma Module introduces structured ways to summarize e-commerce data using SQL. The materials explain how grouped queries work and how summary functions can help organize large sets of records into clearer reporting views. Learners practice building reports around order counts, item quantities, customer activity, category totals, and date-based patterns. 

What’s Inside
Luma Module includes detailed materials focused on summary reporting for e-commerce data. The course begins by explaining the difference between individual records and grouped results. Learners review examples where row-level data is useful, such as checking specific orders, and examples where summaries are more helpful, such as reviewing order counts by category or customer activity by period.

The tier then introduces grouped query structure in a clear sequence. Learners study how to group data by customer, product category, order status, date field, or item type. The materials explain how summary functions can be used to count records, total quantities, calculate averages, and organize results around a reporting purpose. Each example is connected to store-style questions so learners can see why the query is being written, not only how it works.

Luma Module also includes lessons on calculated fields. Learners explore how calculated columns can support order value review, item-level totals, and simple comparison views. The materials show how to keep calculations readable and how to label output fields so reports are easier to understand.

Practice sections include guided scenarios such as reviewing total orders by status, comparing item quantities by category, counting customer order activity, checking date-based order patterns, and preparing simple summary tables. Each activity encourages learners to think about grouping choices, output readability, and report purpose.

Who is this for?
Luma Module is for learners who already understand basic SQL selection, filtering, sorting, and simple table connections. It is suitable for learners who want to improve their ability to summarize store-style data and create clearer reports from large record sets.
