Study Notes
Big Data and NoSQL
- Big data refers to large volumes of data exceeding the capacity of traditional software.
- This data is often unstructured or semi-structured, originating from various sources like social media and emails.
- Key characteristics of big data include volume (quantity), velocity (rate of entry), and variety (formats).
- NoSQL databases, a new generation, differ from traditional relational SQL databases in storing data (not in tables) and using non-SQL languages.
- NoSQL, often interpreted as 'Not only SQL,' uses alternative technologies to store big data and is particularly useful for applications requiring high availability, as seen in social media services.
- NoSQL excels in ease of use, scalability, resilience, and availability.
- NoSQL stores unstructured or semi-structured data, frequently in key-value pairs or JSON documents.
NoSQL Data Models
-
Key-Value (KV) Databases:
- Simplest NoSQL model.
- Stores data as key-value pairs.
- The key acts as an identifier for the value.
- Values can be anything like text, images, or XML documents.
- The database doesn't analyze the value; applications do.
- Lack of foreign keys simplifies processing, making KV databases fast and scalable for basic functions.
-
Column-Oriented Databases:
- Relies on traditional relational database technology but stores data column-wise (column families) instead of row-wise.
- Optimizes read operations, as often only specific columns are needed.
- Useful for storing large volumes of data where frequently accessed related columns are grouped.
-
Graph Databases:
- Based on graph theory.
- Represents data through nodes (entities) and edges (relationships).
- Edges describe node relationships with attributes.
- Useful for highly interconnected data, like social media networks.
-
Document-Oriented Databases:
- Similar to key-value databases; data in tagged documents.
- Stores data in flexible JSON format.
- Documents can have varying column structures across documents.
- Suitable for applications that require dynamic data schemas.
Document-Oriented Database Example - MongoDB
-
Data Structure:
- Documents are the basic data unit, similar to rows but with a flexible schema.
- Each document has a unique id key.
- Documents are stored in collections, analogous to tables.
-
Operations:
- New databases are created automatically if they do not already exist.
- The
db
command displays the currently selected database. - The
show dbs
command lists databases. - Inserting documents, similar to creating rows in a relational database but more flexible.
- Querying documents (e.g., using
find()
). - Removing documents or collections.
