PostgreSQL & its key features

PostgreSQL

PostgreSQL, or Postgres for short, is an advanced, open-source relational database system that has been continuously developing now for over three decades.

Focusing on standard compliance, extensibility, and robustness, PostgreSQL is fundamentally applied in applications that require complex data manipulation, high availability, and scalability.

Some of the main companies using PostgreSQL for analytics and data storage are Apple, Fujitsu, and Cisco.

Key features that set PostgreSQL apart

PostgreSQL is well known for its rich sets of features, which help developers implement and handle various complex data and application needs.

Advance Data Types

JSONB: It stores JSON data in a binary format to speed up computations and give superior indexability.
Arrays and Hstore: Multidimensional arrays are supported, and there are also two very well-implemented types for storing key-value pairs. PostgreSQL is ideal for applications that require the flexibility of storing certain types of data.
Geospatial Data with PostGIS: The PostGIS extension turns PostgreSQL into a very handy geospatial tool, providing geospatial operations.

Full-Text Search

PostgreSQL comes with built-in full-text search capabilities that support extremely complex search queries without relying on any kind of search engine. Content-heavy applications take full advantage of this feature.

Rich Indexing Options

GIN, GiST, BRIN Indexes: PostgreSQL offers several index types, each optimized differently for various query patterns and data. For example, GIN is designed particularly for JSON data; BRIN is better suited for large data when the data has a natural order.

Foreign Data Wrappers

Foreign data wrappers allow PostgreSQL to access external databases and sources of data, enabling remote direct queries for data sources in external data sources from within PostgreSQL. It’s extremely useful for ETL operation as well as data warehousing.

MariaDB & its Key Features

MariaDB

MariaDB was created as an alternative to MySQL because people were worried about Oracle purchasing MySQL.

MariaDB is mostly compatible with MySQL, which makes the movement for users easy between both, and this has brought great improvements in performance and new features.

Having gained popularity as an open source, MariaDB has found its way to becoming one of the preferred databases used in web applications, especially those built on MySQL.

Key features of MariaDB

MariaDB is MySQL-compatible but a bit different from its ancestor, offering many more unique features.

Storage Engines

Aria: It is the crash-safe version of MyISAM, Aria is good for applications performing high-speed read operations.
ColumnStore: ColumnStore is analytics-oriented to store the data. This ColumnStore engine will allow for fast, parallel processing. Thus, for applications such as data warehousing and OLAP data, MariaDB would work very well.
XtraDB: This is a version of InnoDB optimized and highly capable of serving other transaction processing-intensive platforms.

Dynamic Columns

MySQL Dynamic Columns-MariaDB provides dynamic columns, which makes flexible designs of the schema very feasible. Users can easily store different columns in one table because of the type of data.

This pattern is useful when there are some attributes that change significantly across the different records in a given table.

Thread Pooling

The thread pooling feature in MariaDB improves its capability to hold a large number of concurrent connections, making it suitable for web applications that have heavy traffic.

JSON Functions and Virtual Columns

JSON Functions: Similar to PostgreSQL’s JSON support, MariaDB includes functions for manipulating JSON data, though it lacks PostgreSQL’s JSONB indexing.
Virtual Columns: Virtual columns allow the creation of derived data without taking up additional storage, useful for calculated fields.

Interesting Facts about PostgreSQL & MariaDB

PostgreSQL and ACID Compliance

PostgreSQL takes ACID compliance (Atomicity, Consistency, Isolation, Durability) so seriously that it’s sometimes called the “Swiss Army Knife” of databases. It’s a favorite for applications requiring strict data consistency, especially in fields like banking and healthcare.

MariaDB’s Storage Engines that are pluggable

MySQL was based on allowing multiple storage engines, so it’s fairly flexible in terms of performance. For example, the Aria storage engine exists only under MariaDB and is optimized for complicated transactions, while InnoDB is meant for high-performance applications.

Open Source Royalty: PostgreSQL

PostgreSQL is affectionately known as the “most advanced open source database” to many members of the PostgreSQL community. Since 1986, this database has been developed from the passion of enthusiastic community members and is thus considered to be a “veteran” with an uninterrupted flow of improvements.

Parallel Query Processing in PostgreSQL

An important characteristic of PostgreSQL is its ability to perform parallel query processing. This allows for very significant performance improvements when running queries that are quite complex, as the processing can be spread work to many CPU cores. This is a huge asset for any data-intensive application and is one of the main reasons that many data scientists love PostgreSQL.

NoSQL Hybrid: PostgreSQL’s JSONB

With PostgreSQL, you get the SQL as well as NoSQL capabilities all packed into one by including both capacities within a single data type known as JSONB. This may also be combined with relational data with JSON documents in a single database; hence, it is highly versatile for hybrid data needs.

MariaDB’s Geographic Information Systems (GIS) Support

MariaDB supports GIS (Geographic Information Systems), ideal for mapping applications and other projects involving spatial data. It is also used popularly in web-based applications wherein speed and agility are becoming the norm.
