# Data Processing

{% hint style="info" %}

#### Overview 

You can extract meaningful insights and ensure the effective utilization of data with Data Catalog processing. The significant stages in the processing of data are:

1. **Metadata Ingest**
2. **Data Profiling** (for structured data) and **Data Discovery** (for unstructured data)
3. **Data Identification** for structured data, including delimited files
4. **Usage Statistics** for the Microsoft SQL and Oracle databases
5. **PII Detection**

{% hint style="warning" %}
For optimal performance, keep your selection within a practical limit. Processing a very large number of tables, i.e. 100,000, can drastically reduce speed. The default settings on the Configure Data Profiling page generally fulfill most needs and are recommended.

4. Click 'Process'.
