Data is no longer treated as a byproduct of business operations and has become one of the most valuable organizational assets. Every interaction on a banking application, e-commerce platform, hospital system, logistics network or social media service generates data continuously. As organizations increasingly adopt digital workflows, cloud platforms, machine learning systems and real-time applicati
In modern data-driven organizations, managing and analyzing data efficiently is critical. OLAP (Online Analytical Processing) and OLTP (Online Transaction Processing) are both integral parts of data management, but they have different functionalities. Understanding how they differ, and how they complement each other is essential for anyone working with data systems. Online Transaction Processing (
SQL is widely known for data querying and manipulation but systems do grow; data becomes larger; processes become repetitive and operations become sensitive. SQL has some features which enables it to be considered a fully fledged programming language. Some of the features which I discuss in this article are procedures, functions and transactions. Each of these concepts serve distinct purposes. Sto
Three days of guided exercises. Today — no template, no "here's the complete code, just copy and paste." Just a brief: based on what you know — build your WishList contract. A personal WishList where only the owner can fulfill a wish. Small enough to finish in one session. Not so small that the decisions made themselves. Code: github.com/alena-dev-soft/solidity-learn/contracts/04day/ The first thi
Day 3: Voting, Sybil Attacks and Identity Day 3 was the first day that felt like actual software engineering rather than syntax tourism. The task: write a voting contract. Simple enough on the surface - until you start poking at the security model and realize the whole thing has serious gaps in its logic. What looked like a toy example turned out to be a good proxy for real system design problem
Day 2: Access Control Counter.sol - a little better than "Hello World", right? The goal: write a simple Counter contract - increment, decrement, reset - // SPDX-License-Identifier: MIT pragma solidity ^0.8.0; contract Counter { uint256 public count; address public owner; constructor() { owner = msg.sender; count = 0; } function increment() public {
A .NET Dinosaur in Web3 — Day 1: First Smart Contract I've been writing .NET for many years. Today I deployed my first smart contract. I'd like to share my journey into Web3 — every single day. I love what I do — really. I'm a .NET Dinosaur and Azure-passionate developer, Instead of drowning in YouTube tutorials and boring courses, I did something Think of it as a personal trainer who never judg
選定理由 Paper: https://arxiv.org/abs/2512.01020 【社会課題】 【データの設計と従来技術の限界】 Issue Tree（法的論点ツリー）に変換し、葉ノードに対しルーブリック基準を適用可能にした。原告・被告・裁判所の主張をツリー構造で整理した約24,000インスタンスのデータセットを構築。評価軸は「論点カバレッジ」と「正確さ」の2次元。以下がサンプルである： 【原告の主張】被告は540万円を支払え └─【原告】保険金の支払い義務がある ├─【原告】死亡は突発的・偶発的な事故だった │ └─【原告】餅を食べて窒息死＝外因による傷害 │ └─【被告】死因は既往症の可能性が高い └─【裁判所の結論】突発的事故と認定 ただし窒息死は証明不十分 この
