Auto-EDA

Automated Exploratory Data Analysis. Simplifying Data Exploration.

You can check some examples in the documentation.

Basic data exploration on databases currently supporting:

• MSSQL Server
• MySQL
• SQLite
• PostgreSQL
• Oracle

Given two connections, a source and target database, it will collect metadata for a exploration such as:

• Number of rows and columns.
• Number of distinct values and nulls per column.
• Distribution of the categorical variables.
• Statistics of the numerical variables.
• Trends from time series data.

The metadata from the source database will be stored in a metadata database that it will be accesible for any visualization tool to explore it.

How To use AutoEDADB

• Clone or download the package.
• Create two connections as described here to a source database and to the metadata database.
  • Source database: This is the DB you want to explore. You don't need any additional information, just a valid connection to the database.
  • Metadata database: It can be created if not exists. This database will store the information from the source databases.
• Edit the two connection strings and then the call of describe_server(<YOUR_SERVER>) in explorer.py.
• Run it with python explorer.py

To Do

• Using samples for large tables.
• Update frequencies at once after collecting all the distinct values.
• Encapsulate SQL code and reference it by engine: 'sqlserver', 'mysql', 'postgres', 'sqlite', etc.
• Add multithreading processing to the queries.
• Resume mode, now it deletes and insert again.
