+# FOCUS query library
+
+This article outlines a collection of SQL and KQL queries that can be used with a data store that hosts FinOps Open Cost and Usage Specification (FOCUS) data. Use the queries here to explore your data in [Microsoft Fabric](../fabric/create-fabric-workspace-finops.md) or [FinOps hubs](../toolkit/hubs/finops-hubs-overview.md) with Data Explorer.
+
+<br>
+
+## Prerequisites
+
+Before you can execute these queries, you must have:
+
+- A KQL or SQL database, like Azure Data Explorer or a Microsoft Fabric lakehouse or eventhouse.
+- Create a table named "Costs" that uses a FOCUS 1.0 schema.
+- Ingest cost from Microsoft and optionally other cloud or SaaS providers based on your needs.
+
+If you do not have a database, consider one of the following options:
+
+- [FinOps hubs](../toolkit/hubs/finops-hubs-overview.md) with Data Explorer
+- [Microsoft Fabric lakehouse](../fabric/create-fabric-workspace-finops.md)
+
+<br>
+
+## Account structure
+
+Different providers have different account constructs that FinOps practitioners use for allocation, reporting, and more. Organizations may have one or many accounts within one or more providers and FinOps practitioners may need to review the cost broken down by each account. FOCUS has two types of accounts: a billing account and a sub account.
+
+A billing account is the account where invoices are generated. Each billing account can have one or more sub accounts, which can be used for deploying and managing resources and services. Billing and sub accounts are often used to facilitate allocation strategies and FinOps practitioners must be able to break costs down by billing and sub account to facilitate FinOps scenarios like chargeback and budgeting.
+
+### Example: Cost breakdown by account
+
+**KQL**
+
+```kusto
+Costs
+| where BillingPeriodStart == startofmonth(now(), -1)
+| summarize
+    BillingAccountName = take_any(BillingAccountName),
+    BillingAccountType = take_any(BillingAccountType),
+    SubAccountName     = take_any(SubAccountName),
+    SubAccountType     = take_any(SubAccountType),
+    BilledCost         = sum(BilledCost)
+    by
+    BillingAccountId,
+    SubAccountId
+```
+
+**SQL**
+
+```sql
+SELECT
+  BillingAccountId,
+  BillingAccountName,
+  BillingAccountType,
+  SubAccountId,
+  SubAccountName,
+  SubAccountType,
+  SUM(BilledCost)
+FROM Costs
+WHERE BillingPeriodStart = DATEADD(month, -1, DATEADD(month, DATEDIFF(month, 0, GETDATE()), 0))
+GROUP BY
+  BillingAccountId,
+  SubAccountId
+```
