impertio-studio Bundle Mariadb Agents Schema ReviewerUse when reviewing a proposed MariaDB schema before it ships, auditing an existing schema for engine / indexing / naming / normalization problems, or validating a migration DDL. Prevents the common mistake of shipping a schema with MyISAM tables, UUID-text PKs, missing tenant indexes, utf8 charset, or composite indexes in the wrong column order. Covers a deterministic schema-review checklist : storage-engine choice, primary-key type, indexing strategy and column-order, charset / collation, normalization fitness, multi-tenant pattern detection, naming-convention adherence, with severity grading and cross-references to mariadb-core-storage-engines, mariadb-syntax-indexing, mariadb-impl-schema-design. Keywords: schema review, schema audit, review my schema, is this schema correct, schema checklist, design review, storage engine audit, index audit, primary key audit, normalization check, multi-tenant check, naming convention, DDL review, before I ship this schema, ENGINE=InnoDB, MyISAM, BIGINT AUTO_INCREMENT, UUI
