I'm not technical. Can I work with iDev?

Absolutely. Most of our clients are non-technical. Just tell us what you want the end result to look like — we handle all the technical details.

How much does it cost to hire iDev?

We quote individually based on project scope and complexity. Initial consultation is completely free — we give you a clear quote after understanding your needs. No fit, no charge.

How big is the iDev team?

A few core members, each capable of delivering full-stack independently. We flexibly assign people based on project scale and can run multiple projects simultaneously.

What happens after project delivery?

We provide complete code and documentation at handover. For ongoing feature development or maintenance, we offer monthly or per-project arrangements. Most clients choose long-term collaboration.

What if I'm not satisfied with the project midway?

We confirm with you at every stage before moving forward. If the direction is off, we adjust immediately. If it truly can't continue, completed work is settled normally and all code is yours.

我完全不懂技术，能合作吗？

当然可以。我们的大部分客户都不是技术背景。你只需要告诉我们你想要什么效果，技术实现的事情完全由我们来处理。

费用大概是多少？

根据项目复杂度和功能范围单独报价。初次沟通完全免费，我们会在了解需求后给出明确报价，合适再开始，不合适不收费。

团队有几个人？

核心团队几个人，都是能独立交付的全栈开发者。根据项目规模灵活安排人手，可以同时推进多个项目，不用等排期。

项目做完以后怎么维护？

交付时会提供完整的代码和文档。后续如果需要功能迭代或维护，可以按月或按次合作。大部分客户选择了长期合作。

做到一半不满意怎么办？

每个阶段交付前都会和你确认。如果方向不对，我们及时调整。如果实在无法继续，已完成的部分正常结算，代码归你。

iDev SchemaEvolve 发布：数据库模式迁移的安全利器

iDev SchemaEvolve Launch: The Safe and Reliable Database Schema Migration Tool

| iDev Product | 2026-09-01T09:43:17

iDev 推出 SchemaEvolve 数据库模式迁移工具，提供零停机迁移、自动回滚、影响分析与多数据库支持能力。

iDev launches SchemaEvolve, a database schema migration tool offering zero-downtime migration, automatic rollback, impact analysis, and multi-database support.

iDev SchemaEvolve：让数据库变更不再令人恐惧数据库模式变更是软件开发中风险最高的操作之一。一次不当的 ALTER TABLE 可能导致长时间的锁表、服务中断甚至数据丢失。iDev SchemaEvolve 是一款专注于安全、可靠数据库模式迁移的工具，让 DBA 和开发者可以自信地执行模式变更。核心功能零停机迁移：采用影子表策略（Shadow Table）和在线 DDL 技术，大表变更不锁表影响预分析：执行前自动评估迁移对查询性能、索引和外键的影响自动回滚计划：每次迁移自动生成逆操作脚本，支持一键回滚迁移编排：支持多步迁移的依赖编排和条件执行审计日志：完整记录谁在何时执行了什么变更，满足合规要求安全机制SchemaEvolve 内置多重安全检查：阻止没有 WHERE 条件的 UPDATE/DELETE、检测可能导致数据截断的列类型变更、拒绝在业务高峰期执行大规模迁移。所有迁移操作在沙箱环境中预演通过后才允许在生产环境执行。数据库支持SchemaEvolve 支持 MySQL 5.7+、PostgreSQL 12+、SQL Server 2019+ 和 Oracle 19c+。每种数据库引擎都有针对性的优化策略，例如 MySQL 使用 pt-online-schema-change 算法，PostgreSQL 利用其原生的并发索引创建能力。iDev SchemaEvolve 提供开源社区版（单数据库支持）与企业版（多数据库、团队协作、审批流）。

iDev SchemaEvolve: Making Database Changes FearlessDatabase schema changes are among the highest-risk operations in software development. An improper ALTER TABLE can lead to prolonged table locks, service outages, or even data loss. iDev SchemaEvolve is a tool focused on safe, reliable database schema migration, enabling DBAs and developers to execute schema changes with confidence.Core FeaturesZero-Downtime Migration: Shadow table strategy and online DDL techniques ensure large table changes without lockingPre-Migration Impact Analysis: Automatically evaluates migration impact on query performance, indexes, and foreign keys before executionAutomatic Rollback Plans: Automatically generates reverse operation scripts for each migration with one-click rollback supportMigration Orchestration: Supports dependency orchestration and conditional execution for multi-step migrationsAudit Logging: Complete records of who executed what changes and when, meeting compliance requirementsSafety MechanismsSchemaEvolve includes multiple built-in safety checks: blocking UPDATE/DELETE without WHERE conditions, detecting column type changes that may cause data truncation, and refusing large-scale migrations during peak business hours. All migration operations must pass sandbox rehearsal before being permitted in production.Database SupportSchemaEvolve supports MySQL 5.7+, PostgreSQL 12+, SQL Server 2019+, and Oracle 19c+. Each database engine has targeted optimization strategies; for example, MySQL uses the pt-online-schema-change algorithm, while PostgreSQL leverages its native concurrent index creation capabilities.iDev SchemaEvolve is available as an open-source Community Edition (single database support) and an Enterprise Edition (multi-database, team collaboration, approval workflows).
