| **2d.** | Data interface: Deployment | We will provide developers with the ability to schedule their customer view’s deployment (automatically at recurring times in the future milestones). The deployment action will be a UI module, and the propagation/consensus will occur via GitHub at first and via a PGSQL query in future milestones.|


### Milestone 4 — Interactive SQL Query Engine for Views

- **Estimated Duration:** 1.5mos
- **FTE:** 4
- **Costs:** 7,500 USD

- Summary: This milestone covers a SQL editor as a new option for developers/users to productionize views on FiDi via specific squids on GiantSquid.
- Success: developer UI supports FiDi SQL-powered views.

| Number | Deliverable | Specification |
| -----: | ----------- | ------------- |
| **0a.** | License | Apache 2.0
| **0b.** | Documentation | We will provide documentation on querying methodology, e.g., functions, operators, data types, and statement reference; as well as an educational tutorial explaining the typical way to run the queries, associate them with the views, interpret the data, navigate the developer UI, and share the views. |
| **0c.** | Testing | Core functions will be fully covered by a unit and integration tests suite to ensure robustness, deployment, and serving times. |
| **0e.** | Article | We will publish an announcement article capturing the work completed in the grant along with the educational guides and success stories, enabling users to further leverage and expand DotSight’s functionality. |
| **1.** | FiDi SQL implementation | We will provide a query engine for blockchain data. Initially forked from [TrinoSQL](https://trino.io/) and/or [harmonizer](https://github.com/duneanalytics/harmonizer), we will extend the functionality to support variable views and embed GraphQL upstream queries. We'll simialrly rely on Typescript + Nest + CloudSQL (PGSQL) for the query engine's implementation. ![FiDi SQL Engine UI Example](https://storage.googleapis.com/fidi-tech-static1/w3f/FiDi%20SQL%20Engine.png "FiDi SQL Engine UI Example")|
| **2.** | SQL Editor View UI | We will augment the no-code view developed in Milestone 2 with SQL functionality allowing users to rehash the existing views as well as create new ones. The Editor UI will include the runner log, a tree of dependencies and suggested resources, and the editor interface itself. See the UI direction in the following wireframe:|
| **3.** | Advanced Querying Documentation | We will provide a comprehensive guide for optimizing the queries, both language- and database-specific, along with real-world examples |


## Future Plans
DotSight will provide a scalable, incentivized platform for developers to contribute to the Polkadot ecosystem's growth by integrating new protocols and on-chain metrics. We aim to continue extending the number of parachains with advanced analytics supported on FiDi, the breadth and depth of analytical dashboards, and the pre-developed squids available.
