Agile Data - Domain Model and Persistance framemwork

Agile Data is a unique library that enforces correct design of Business Logic in your PHP application and handles persistence (interaction with database) in flexible and scalable way.

• Business Models - Implement a clean business logic [DM].
• Active Record - Use this when you need individual record access [DM].
• Explicit Loading and Saving - Don't rely on framework to do loading magic for you. Load data yourself. [PM]
• Relation Mapping - Traverse between business data [DM].
• Persistence - Design and tweak how your Business Models are mapped into tables [DM->PM].
• Derived Queries - Express your Business Models as SQL queries [PM].
• Expressions - Use Derived queries to add fields in your Business Models that are calculated in SQL [PM].
• Query Building - Build an execute complex multi-row queries mapped from your Business Models [PM].
• Unit-testing - Business Models can be decoupled from persistence layer for efficient Unit Testing [DM].
• Aggregation and Reports - Support report generation techniques, aggregation and unions for your Business models [DM].

Our design goals are: (old list)

• Design around existing challenges in ORM, ActiveRecord and SQL Builders.
• Come up with a clean concept before coding.
• Implementation must be simple for new developers and powerful enough for seasoned geeks.
• Educate developers on efficient database use instead of resorting to "hacks" (pre-fetching etc).
• Any Query. Should be usable with any database schema and produce any request.
• PDO/SQL Vendor support as well as NoSQL vendor support.
• Take full advantage of Vendor features where possible (sub-queries, derived query, expressions)
• Never execute hidden queries.
• Keep low overheads. Small code footprint.
• Allow to fully separate "Business Models" from "Persistence logic".
• Provide reliable way to Unit-test Business Logic and all operations without need of default database.
• Minimum requirements, PHP 5.5+.
• Full unit test coverage, standard compliance, detailed documentation.
• License under MIT.
