Free and open source database software provides a compelling option for storing and managing data without incurring expensive licensing fees. From hobbyists working on personal projects to startups launching new products, open source databases empower you with enterprise-grade capabilities that can scale from small datasets to massively distributed cloud infrastructure.

This definitive guide explores the world of free database software and equips you with expert knowledge to select the right platform for your needs. Let‘s dive in!

Overview of Core Database Architectures

When evaluating database options, you‘ll encounter two primary architectural models:

SQL Databases: These traditional relational databases organize data into tables with predefined schemas. They provide simplicity and robust tools for structured data but can require more planning as needs evolve.

NoSQL Databases: Also known as non-relational databases, these more flexible platforms store unstructured or semi-structured data using models like key-value pairs, graphs, and documents. NoSQL scales well but may lack some features of mature SQL systems.

Both open source SQL and NoSQL come in a variety of flavors with unique capabilities. Your application‘s specific requirements around transactions, reporting, scalability, and data types will determine the best approach.

Key Benefits of Using Open Source Databases

Choosing open source over proprietary databases offers several clear advantages:

• Significant cost savings – Avoid vendor lock-in and expensive commercial licensing fees.
• Flexibility – Modify and extend databases to suit your needs.
• Access to source code – Enhance security and troubleshoot issues.
• Control – Take charge of upgrades rather than being forced into them.
• Community support – Leverage knowledge and contributions from a global community.

Of course, open source lacks official support services, which may be unacceptable for mission-critical workloads. However, many vendors offer support packages at additional cost on an as-needed basis.

Evaluating SQL Database Options

SQL databases remain a versatile, battle-tested choice for many applications because of their maturity and rich tooling. Let‘s explore leading open source relational database options…

The world‘s most popular open source database, MySQL offers proven performance, reliability, and ease of use. Its relational model provides effective tools for both operational applications and analytics use cases. MySQL scales well through sharding techniques that horizontally partition data across servers.

• High traffic web apps
• Ecommerce platforms
• Datastore for programming languages
• Battle-tested reliability
• Feature-rich ecosystem of GUI tools
• Widely supported across industry
• Lacks full compliance with SQL standards
• Sharding adds complexity
• Risk of Oracle changing license terms

Over 50% of all websites leverage MySQL. Its accelerated development cycles also allow rapid innovation for emerging needs.

However, PostgreSQL has emerged as a leading open source alternative – one that prides itself on standards compliance and extensibility. Let‘s compare the two…

MySQL vs PostgreSQL Comparison

Based on db-engines.com rankings, PostgreSQL and MySQL have very similar adoption globally, with PostgreSQL growing faster annually.

A powerful open source relational database, PostgreSQL prides itself on standards compliance, extensibility, security, and modern feature sets including JSON support, multi-version concurrency control, and streaming replication. An enterprise-grade solution trusted by Apple, Reddit, Instagram and more, PostgreSQL rivals top commercial databases.

• Business analytics
• Scientific data analysis
• Custom applications
• Highly extensible and customizable
• Great performance via advanced indexing
• Committed community of global developers
• Initial setup/administration can be complex
• Risk of compatibility issues across major updates
• Not as turnkey as MySQL

Given its enterprise capabilities and passionate community, PostgreSQL offers a compelling route as needs grow in complexity. Companies rarely outgrow its robust platform.

If seeking a minimalist, embeddable database, SQLite is another compelling open source option.

With origins tracing back to 2000, SQLite provides a remarkably compact yet full-featured SQL engine. Unlike client-server database models, SQLite does not run as a separate process. It instead operates as an embedded component directly integrated within end-user applications. The entire database exists as a single cross-platform disk file.

• Mobile apps
• Embedded devices
• Internal application data storage
• Zero configuration – no complex installation
• Cross-platform ACID-compliant transactions
• Small disk and memory footprint
• Lacks some advanced SQL features
• Not ideal for enterprise applications
• Risk of data corruption if not shut down properly

For mobile apps and devices, SQLite helps developers avoid obstacles with minimal footprint and solid performance. But for more complex reporting needs, other SQL options are recommended.

Cloud-Hosted SQL Database Options

Increasingly, databases are deployed to the cloud to reap benefits like elastic scalability, high availability configurations, and reduced hardware management.

Top cloud data platforms include:

Azure SQL Database

Fully managed PaaS by Microsoft built on latest stable SQL Server database engine. Available in single, pooled, and hyperscale resource models.

Amazon Relational Database Service (RDS)

RDS simplifies deploying scaled MySQL, PostgreSQL, Oracle, SQL Server, and MariaDB databases in AWS. RDS handles infrastructure provisioning, software patching, backups, and failover.

Both options provide turnkey availability, security protections, and flexibility – at an added cost over self-managed open source deployments.

Benchmark Comparison of Top SQL Solutions

Figure: SQL Platform Benchmark via selectstar.io, higher is better

As shown above, PostgreSQL and MySQL offer leading price/performance – but consider your own use case patterns.

Now let‘s shift gears to…

Review of NoSQL Database Options

Sometimes relational models are overkill. For modern apps dealing with semi-structured data, NoSQL databases provide welcomed flexibility. I‘ll overview top options…

A wildly popular document store NoSQL database, MongoDB provides dynamic schema design that allows storing data in flexible JSON-like documents rather than rows/columns. Developed by MongoDB Inc., the platform delivers extensive tooling, commercial support options, and a robust ecosystem.

• Content management
• Real-time analytics
• IoT data storage
• Intuitive data model based on BSON documents
• Rich querying and indexing capabilities
• Easy horizontal scaling w/ built-in replication
• No multi-document ACID transactions
• Administration can be challenging
• Requires capacity planning

For many modern apps, MongoDB strikes a great balance between scalability and ease of use – minus some data integrity guarantees. Over 100,000 organizations use MongoDB in production, including Adobe, Forbes, and eBay.

Apache Cassandra

Designed for scalability across commodity servers with no single point of failure, Cassandra offers top performance for write-intensive applications. Its distributed architecture provides enterprise-grade durability and fault tolerance. However, complex data models can become cumbersome.

• High volume IoT messaging
• Time series data
• Product catalog
• Proven extreme scalability
• Tunable consistency levels
• Multi-data center support
• No native aggregation features
• Steep learning curve
• Stagnant community innovation

If your application demands unprecedented scalability, Cassandra warrants a deep look – despite its steeper learning curve. Leading companies depending on Cassandra include Netflix, Apple, Instagram, Spotify, and DirecTV.

An open source in-memory data store, Redis excels at ultra-fast operations involving static data access and mutable data structures like strings, lists, maps, sets, sorted sets and more. By persisting data to disk, it combines high performance with durability.

• Caching layer
• Message brokering
• Gaming leaderboards
• Exceptional benchmark performance
• Rich set of data structures
• High availability configurations
• Advanced administration required
• Risk of losing data if no persistence
• No built-in clustering

If your use case fits, Redis offers blazing speed and unique capabilities. However, its niche as a non-durable datastore mandates redundancy planning for production systems.

NoSQL Database Capabilities Overview

Figure: How leading NoSQL databases compare by features

As shown above, multiple NoSQL platforms merit consideration based on the specific types of unstructured data your application relies on.

Next let‘s switch gears to cover…

Choosing the Right Open Source Database

With so many database options to evaluate, focus first on your primary requirements around:

• Data Models – Do object vs. table structure matter? Graph?
• Functionality – Which access patterns are essential?
• Scale – Read/write throughput needed today and in future?
• Performance – Read/write latency thresholds?
• Availability – Clustering? Failover speed? Durability levels?
• Ecosystem – Tooling and support ecosystem maturity?

Seeking community advice can be invaluable during your selection process. Documentation quality also varies greatly across platforms.

Invest time upfront determining proof of concept needs and avoid over-engineering prematurely. You can always migrate to more robust infrastructure later as adoption evolves.

When to Consider a Polyglot Persistence Architecture

In some cases, a hybrid relational and NoSQL architecture makes sense:

• Use SQL for critical transactional data requiring ACID compliance
• Embed a NoSQL database like MongoDB to store session state or less critical data
• Or ingest data into a data lake built on HDFS, then analyze via Spark SQL

Choose the right tool for each specific data storage and processing challenge.

Anti-Patterns to Avoid

Conversely, common missteps to sidestep when getting started:

• Premature optimization without real-world bottlenecks
• Overusing NoSQL “just because”
• Building lifecycle logic into the database layer
• Locking into proprietary software without exploring open source options

Set yourself up for success by aligning business goals with practical data realities.

Migrating to Open Source Databases

Transitioning legacy systems to open source databases reaps tremendous rewards but requires planning. Here is an overview of best practices…

Extract, Transform & Load Data

Leading open source ETL tools include Pentaho, Talend, and Apache Airflow. Use these to…

• Export data from commercial databases
• Cleanse records with custom logic
• Load into desired open source data platforms

Port Applications for Cross-Platform Support

To abstract applications from underlying database volatility, leverage ORM frameworks like Hibernate, Django ORM, or SQLAlchemy. These minimize disruption when transitioning between storage engines.

Instrument & Validate Performance

As you conduct load testing, keep a close eye on key application metrics around:

• Requests per second
• Read/write latency
• Memory utilization
• Query response times

Compare metrics against benchmarks for expected platform performance limits.

Model Future Scalability Needs

Specific capabilities to evaluate when projecting growth:

• Vertical scaling potential via beefier single nodes
• Read replicas for spreading read workloads
• Sharding strategies for horizontal partitioning
• NoSQL caching tiers to reduce database load

Right-size migrations to meet current demands while allowing headroom for the future as adoption increases over time.

Emerging Open Source Database Trends

While traditional databases remain prevalent, surprising new innovations continue disrupting the industry:

Containers & Kubernetes

Packaging databases like PostgreSQL and MySQL into Linux containers helps isolate apps, deliver portability, and speed up deployment. Popular container orchestration platforms like Kubernetes then auto-scale infrastructure across on-prem or cloud infrastructure.

Serverless Architectures

Leveraging serverless platforms like AWS Lambda to run code snippets on-demand without managing underlying resources also applies to databases. Purpose-built serverless databases like Aurora Serverless offer event-driven invocation with auto-scaling capacity.

Graph databases

Graph databases like Neo4j optimize storage and queries based on highly connected data points and relationships most naturally modeled as nodes and edges in graphs. Powering fraud detection and recommendation engines, graph databases continue gaining adoption in specialized use cases involving complex interconnections.

Understanding these bleeding edge trends helps future-proof decisions and stay at the forefront of lightning fast innovation.

The database landscape offers extreme diversity – along with endless opportunities to capitalize on the unique strengths across both SQL and NoSQL options.

I hope this guide has demystified the world of open source database software and illuminated pathways to tremendous value. Avoid vendor lock-in, leverage community innovation, and unlock next-generation data platforms.

The time is now to migrate your application or prototype ideas using freely available tools aligned with your technical and business requirements. Master these technologies and seat yourself at the leading edge of the data landscape!

Irkutsk Oblast, in particular the capital Irkutsk and the shores of Lake Baikal , is likely Siberia 's top travel destination.

Russian is understood and spoken by all; some members of ethnic minorities (especially the Buryat) are bilingual and speak their native languages with one another.

Irkutsk Airport ( IKT   IATA ) is one of Russia 's most important and receives international flights from Mongolia , China , South Korea , Thailand , and Uzbekistan . Domestic flights are available from most major Russian airports, including: Saint Petersburg , Moscow , Khabarovsk , Yekaterinburg , Vladivostok , and many others.

Despite the importance of Irkutsk Airport, most travellers still arrive via the Trans-Siberian Railway , which stops at (from west to east): Taishet (junction with the Baikal-Amur Mainline ), Nizhneudinsk , Usolye-Sibirskoe , Angarsk , Irkutsk , among other less frequented settlements.

Baikal Highway crosses the region from west to east. A bus from Ulan-Ude connects Irkutsk with Buryatia.

Bratsk and Ust-Orda are accessible via the Baikal-Amur Mainline from the Trans-Siberian Railway junction at Taishet.
