# AGDB Time Series Graphs and Query Structure

Active Graph Databases (AGDBs) are an innovative framework designed for efficiently managing and querying time-series data. By leveraging **Active Graph Theory (AGT)** and **Active Graph Networks (AGN)**, AGDBs enable the creation of structured and synthetic relationships that can scale across various domains while maintaining efficiency in both small and large datasets.

## Overview of AGDB Architecture

AGDB utilizes a hierarchical time-based structure combined with synthetic relationships to enable efficient querying and scalable handling of complex data. This design facilitates cross-domain contextual relationships, supporting advanced data interactions, rule-based querying, and scalable, efficient processing.

## Structure of AGDB Time Series Graphs

AGDB structures time-series data through hierarchical **Time Nodes** and **Data Nodes**. Synthetic relationships within the database enable efficient traversal and retrieval of specific time points or patterns, allowing AGDB to act as a powerful framework for scalable time-series querying.

### AGDB Structure Diagram

```mermaid
graph TD
  TimeHierarchy[Time Hierarchy]
  Year[Year]
  Month[Month]
  Day[Day]
  Hour[Hour]
  Minute[Minute]
  Checkpoints[Predefined Checkpoints]
  Data[Data Nodes]

  TimeHierarchy --> Year
  Year --> Month
  Month --> Day
  Day --> Hour
  Hour --> Minute
  Minute --> Data
  TimeHierarchy --> Checkpoints
  Checkpoints --> Minute
  Checkpoints -->|Synthetically link| Hour
```

- **Hierarchical Structure**: Organized from Year down to Minute, each node level enables efficient time-based navigation.
- **Checkpoints**: Serve as reference points within the hierarchy, allowing quicker access to relevant data via synthetic pathing.
- **Data Nodes**: Store attributes for each time interval, making each data point easily accessible.

## Query Structure for AGDB

The query structure for AGDBs supports flexible access to data across predefined and synthetic relationships. Using a path-based syntax, AGDB queries are intuitive and efficient for time-series and context-rich data.

### Example Query Structure

```mermaid
graph LR
  Year2024[2024]
  Month11[November]
  Day04[4th]
  Hour10[10:00 AM]
  Minute45[10:45 AM]
  DataNode[Data Node]

  Year2024 --> Month11
  Month11 --> Day04
  Day04 --> Hour10
  Hour10 --> Minute45
  Minute45 --> DataNode
  Checkpoint1040[Checkpoint 10:40 AM]
  Checkpoint1040 -->|+5 Minutes| Minute45
```

- **Direct Navigation**: Queries traverse through the year, month, day, hour, and minute levels until reaching the target node.
- **Synthetic Pathing**: Checkpoints at predefined intervals enable rapid traversal, allowing queries to skip to approximate points and increment from there.

## Definitions and Components

### AGT (Active Graph Theory)

AGT provides the foundational logic for defining and managing relationships within AGDB, modeling data as interconnected nodes with contextual relationships.

```mermaid
graph LR
  AGT[Active Graph Theory]
  Nodes[Data Nodes]
  Relationships[Relationships]
  ContextualInference[Contextual Inference]

  AGT --> Nodes
  AGT --> Relationships
  Relationships --> ContextualInference
```

- **Nodes**: Represent data entries or entities.
- **Relationships**: Define connections between nodes.
- **Contextual Inference**: Adds depth to data by inferring relationships based on contextual cues.

### AGN (Active Graph Networks)

AGN utilizes AGT’s principles to support querying and interaction within AGDB. Through rules and policies, AGN automates and simplifies navigation through AGDB.

```mermaid
graph TD
  AGN[Active Graph Network]
  QueryEngine[Query Engine]
  TraversalRules[Traversal Rules]
  SyntheticPathing[Synthetic Pathing]
  Checkpoints[Checkpoints]

  AGN --> QueryEngine
  QueryEngine --> TraversalRules
  TraversalRules --> SyntheticPathing
  SyntheticPathing --> Checkpoints
```

- **Query Engine**: Processes requests by applying AGN’s traversal rules.
- **Traversal Rules**: Define how nodes are accessed based on AGDB structure.
- **Synthetic Pathing**: Creates shortcuts between nodes, improving query efficiency.
