## 2. Installation <a name="installation"></a>
To use DataHive, follow these installation steps:
1. **Install python**: Python 3.x installed on your machine.
2. **Install DataHive**: Install DataHive package on your local machine:
```shell
pip install DataHive
```
## 3. Usage <a name="usage"></a>
### Schema Format <a name="schema"></a>
Below is an example of the schema format that defines the structure of the database, including the database name and tables with their respective attributes:
1. **Schema Example**:
```
{
"database_name" : "ClassA1",
"Tables" : [
{
"name" : "student",
"columns" : ["First_name", "Last_name", "CGPA", "Gender", "Age"],
"primary_key" : "Last_name",
"index_keys" : ["First_name", "Last_name", "CGPA"],
"overwrite" : "True",
}
]
}
```
2. **Table Contents**:
The schema format consists of the following elements for defining tables within the database:
| Name | Type | Nullable | Notes |
| ---- | ---- | -------- | ----- |
| Name | string | No | Name of the table. |
| Columns | List of Strings | No | List of column names, including the primary key. |
| Primary_key | String | No | The primary key for the table. |
| Index_key | List of Strings | Yes | List of column names that serve as index keys. |
| Overwrite | boolean (true/false) | Yes | Initial value is 'false'; you can set its value to 'true' to enable overwriting.|
### Command-Line Interface <a name="commands"></a>
*Note: Ensure that you have a JSON file containing your schema before creating the database.*
| Command | Parameters | Description |
|---------|------------|-------------|
| `Create` | `DatabaseSchemaPath` | Creates a database following the specified [schema](#schema).
| `Set` | `DatabaseName`, `TableName`, `InputData` | Sets a row with the provided input data.
| `Get` | `DatabaseName`, `TableName`, `InputQuery` | Utilizes the input query to retrieve specific data from the database.
| `Delete` | `DatabaseName`, `TableName`, `InputQuery` | Uses the input query to delete specific data from the database.
| `Clear` | `DatabaseName` | Resets the specified database to its initial state.
This Command-Line Interface (CLI) provides a set of commands for creating, updating, querying, deleting data, and resetting databases, offering comprehensive control over your data management tasks.
## 4. Example Usage <a name="examples"></a>
- **The general format for any command in the program is as follows**:
```python
python DataHive -c [command] [options]
```
Replace `[command]` with the desired database command and `[options]` with relevant command options.
- **Commands Examples**:
- Creating a new database:
```python
python DataHive -c create -sc <your_schema_path>
```
- Sets a row with the provided input data:
```python
python DataHive -c set -db <your_database> -t <your_table> -q '{"key": "value"}'
```
- Utilizes the input query to retrieve specific data from the database:
```python
python DataHive -c get -db <your_database> -t <your_table> -q '{"key": "value"}'
# if you didn't add -q it will get all data in the table
```
- Uses the input query to delete specific data from the database:
```python
python DataHive -c delete -db <your_database> -t <your_table> -q '{"key": "value"}'
```
- Resets the specified database to its initial state:
```python
python DataHive -c clear -db <your_database>'
```
