■ Relational Database Management System
・Data consistency & integrity: Ensure that data remains consistent and accurate across the database.
・Scalability: Scale vertically by adding more resources to a single server, and horizontal scaling through sharding or partitioning.
・Flexibility: Handle various data types and structures, and can be customized to meet specific business needs.
・ACID properties: Transactions are Atomic, Consistent, Isolated, and Durable, providing a reliable foundation for data management.
■ NoSQL Database
・Document Store: Stores and retrieves data as semi-structured documents, typically using formats like JSON or BSON.
・Key-Value Store: Stores data as pairs of unique keys and their corresponding values, enabling fast and efficient lookups.
・Column Store: Stores data in columns instead of rows, optimizing for read-heavy workloads and allowing efficient compression and querying.
・Graph Database: Designed for storing and querying complex relationships and interconnected data using nodes and edges in a graph structure.
■ NewSQL Database
Designed to provide the ACID properties and SQL support of RDBMS,
while offering the scalability and performance advantages of NoSQL systems.
・ACID compliance: Ensure data consistency and reliability by adhering to ACID properties for transactions.
・SQL support: Providing a familiar interface for developers and database.
・Horizontal scalability: By adding more nodes, enabling them to handle increasing amounts of data and transaction loads efficiently.
・Distributed architecture: Use distributed consensus algorithms, data sharding, and replication techniques.
■ Time-Series Database
Efficiently store, retrieve, and analyze large volumes of time-stamped data with high write and query rates.
Its unique architecture and indexing mechanisms enable fast data ingestion and time-based querying,
making it ideal for handling time-sensitive data and performing time-based analytics.
・Time-based indexing: Allowing for efficient querying and aggregation of data over specified time intervals.
・compression: Reduce storage overhead and improve query performance, as time-series data can be highly repetitive.
・Retention policies: Automatically expire or downsample older data, optimizing storage and resource usage.
■ In-Memory Database
Designed to handle high-performance, low-latency workloads, such as real-time analytics, caching,
and high-speed transaction processing.
・High performance: By storing data in memory, IMDBs can offer significantly faster read and write operations compared to disk-based databases.
・Real-time analytics: Real-time data processing and analysis, making them suitable for applications that require immediate insights.
・Scalability: In-Memory Databases can scale horizontally and vertically to accommodate increased data volumes and processing demands.
・Data persistence: Optional disk-based storage for data persistence and recovery, ensuring data durability in case of system failures or restarts.

ゆるっとしたスタイルが好きなので、やや大きめにMサイズを選んで肩を落として着るのが定番です。だらしなくなりすぎないように裾はインすることが多いです。厚すぎず薄すぎずでちょうどよい生地です。
夏はこれ1枚で過ごすこともあるので、透けないよう暗めの色で着ています。素材は着ていて涼しいものだと感じます。ジャケットや上着にも合わせやすいので気に入っています。
普段はモノトーンになりがちですが、思い切ってピンクを購入しました!カラーバリエーションが豊富なのが嬉しいです。Lサイズで少し大きめサイズで着ています。柔らかい素材で着心地がとても良いので、シーンを問わずアクティブな場面でもリラックスしたい時間にも着たくなる一枚です。
ラフに着るのが好きで思いきってXXXLを選びました。ただ大きいだけになりがちなビッグサイズですが、スタンダードTシャツはダボダボになりすぎないサイズ感で見た目もキレイなままラフに着れます。素肌にそのまま着心地もよく気に入っています。
