Book Description
Discover the fundamental concepts of object-relational mapping (ORM) design, Aurelius’ basic features, and the practical applications of those features. In a series of tasks, you will be exposed to techniques and best practices that make the use of Aurelius easy and efficient. Furthermore, you’ll refine your analytical skills to sharpen your understanding of Delphi (Pascal), helping you write better code along the way. Introducing Delphi ORM explains that while database design is difficult, database programming (i.e., manipulating, extracting, filtering, and manipulating data) is even more difficult. ORM frameworks provide a simpler way for you to access and manage data in databases. You’ll see how they offer different levels of abstraction and tools to code data access in a database-agnostic way by introducing a layer between the application and the data access language (SQL, LINQ, and so on). By the end of the book, you will be confident in using a wide range of Aurelius features to allow you to get started with databases in a very short space of time. What You Will LearnGain the fundamentals of ORM frameworks and Aurelius for DelphiAchieve basic tasks, such as connecting to the database and adding, deleting, and updating records, using Aurelius Employ advanced database queries Use the TAureliusDataSet component Integrate with mobile platforms such as Android and iOSWork with the data modeler application Who This Book Is For Software developers starting with Aurelius or those who have some exposure to the framework.

Book Description
Object-relational mapping (ORM, O/RM, and O/R mapping) in computer software is a programming technique for converting data between incompatible type systems in object-oriented programming languages. This creates, in effect, a ""virtual object database"" that can be used from within the programming language. There are both free and commercial packages available that perform object-relational mapping, although some programmers opt to create their own ORM tools. This book is your ultimate resource for Object-relational mapping (ORM). Here you will find the most up-to-date information, analysis, background and everything you need to know. In easy to read chapters, with extensive references and links to get you to know all there is to know about Object-relational mapping (ORM) right away, covering: Object-relational mapping, AgileFx, Apache Cayenne, Apache OpenJPA, AutoFetch, Bold for Delphi, Comparison of object-relational mapping software, Datamapper, Doctrine (PHP), Ebean, Hibernate (Java), IBATIS, Java Data Objects, Java Object Oriented Querying, Java Persistence API, List of object-relational mapping software, LLBLGen Pro, MyBatis, Object-relational impedance mismatch, ODB (C++), OpenAccess ORM, ORMLite, PdoMap (PHP), Propel (PHP), IBM PureQuery, Quick Objects, QuickDB ORM, Signum Framework, SQLAlchemy, TopLink, Active database, ADO.NET, ADO.NET data provider, AllegroGraph, Altibase, Animation database, Database application, ArchiveGrid, Associative Entities, Autocommit, Back-end database, BigTable, Binary large object, BioSearch, BrandZ, Brapci, Canada GE3LS, Centralized database, Centralised Information Service for Complementary Medicine, Checkpoint restart, China Economic Databases, Clinical data repository, CLSQL, Collection database, Commitment ordering, The History of Commitment Ordering, Comparison of ADO and ADO.NET, Comparison of database access, Comparison of OLAP Servers, Comparison of structured storage software, Comprehensive Microbial Resource, ConceptBase, Concurrency control, Configuration management database, Connection string, Consensus CDS Project, Covers, Titles, and Tables: Anthologies and The Formations of American Literary Canons, Crystallographic database, CSQL, CSQL Cache, Current database, Current Index to Statistics, DAD-IS, Data administration, Data Composite, Data Description Specifications, Data event, Data item, Data masking, Data pack, Data pool, Data redundancy, Data store, Data system, Database, Database audit, Database caching, Database connection, Dbclient, Java Database Connectivity, Database Deployment Manager, Database design, Database forensics, Database management system, Database Marketing Agency, Database normalization, Database publishing, Database Source Name, Database storage structures, Database virtualization, Datasource, DBMail IMAP and POP3 server, Declarative Referential Integrity, Deductive language, Devgems Data Modeler, DEX (Graph database), DeZign for Databases, Diablo Data Systems, Digital curation, Diplomatic Documents of Switzerland, Directory (databases), Distributed concurrency control, Distributed database, Domain relational calculus, DUAL table, Dynamo (storage system), Dynaset, EJB QL, Elasticity (data store), Emissions & Generation Resource Integrated Database (eGRID), Endgame tablebase, Enterprise database management, Entity-attribute-value model, ER/Studio, ERROL, ESPRID, Event condition action, Federation of International Trade Associations, FlockDB, Fluidinfo, Foreign key, Geodatabase, Glass databases, Global concurrency control, Global serializability, GlobalTrade.net, Graph database, Halloween Problem...and much more This book explains in-depth the real drivers and workings of Object-relational mapping (ORM).

Book Description
Grails is a full stack framework which aims to greatly simplify the task of building serious web applications for the JVM. The concepts within Grails, like interceptors, tag libs, and Groovy Server Pages (GSP), make those in the Java community feel right at home. Grails’ foundation is on solid open source technologies such as Spring, Hibernate, and SiteMesh, which gives it even more potential in the Java space: Spring provides powerful inversion of control and MVC, Hibernate brings a stable, mature object relational mapping technology with the ability to integrate with legacy systems, and SiteMesh handles flexible layout control and page decoration. Grails complements these with additional features that take advantage of the coding–by–convention paradigm such as dynamic tag libraries, Grails object relational mapping, Groovy Server Pages, and scaffolding. Graeme Rocher, Grails lead and founder, and Jeff Brown bring you completely up–to–date with their authoritative and fully comprehensive guide to the Grails 2 framework. You’ll get to know all the core features, services, and Grails extensions via plug–ins, and understand the roles that Groovy and Grails are playing in the changing Web.

Book Description
The practice of enterprise application development has benefited from the emergence of many new enabling technologies. Multi-tiered object-oriented platforms, such as Java and .NET, have become commonplace. These new tools and technologies are capable of building powerful applications, but they are not easily implemented. Common failures in enterprise applications often occur because their developers do not understand the architectural lessons that experienced object developers have learned. Patterns of Enterprise Application Architecture is written in direct response to the stiff challenges that face enterprise application developers. The author, noted object-oriented designer Martin Fowler, noticed that despite changes in technology--from Smalltalk to CORBA to Java to .NET--the same basic design ideas can be adapted and applied to solve common problems. With the help of an expert group of contributors, Martin distills over forty recurring solutions into patterns. The result is an indispensable handbook of solutions that are applicable to any enterprise application platform. This book is actually two books in one. The first section is a short tutorial on developing enterprise applications, which you can read from start to finish to understand the scope of the book's lessons. The next section, the bulk of the book, is a detailed reference to the patterns themselves. Each pattern provides usage and implementation information, as well as detailed code examples in Java or C#. The entire book is also richly illustrated with UML diagrams to further explain the concepts. Armed with this book, you will have the knowledge necessary to make important architectural decisions about building an enterprise application and the proven patterns for use when building them. The topics covered include · Dividing an enterprise application into layers · The major approaches to organizing business logic · An in-depth treatment of mapping between objects and relational databases · Using Model-View-Controller to organize a Web presentation · Handling concurrency for data that spans multiple transactions · Designing distributed object interfaces

Book Description
Essential SQLAlchemy introduces a high-level open-source code library that makes it easier for Python programmers to access relational databases such as Oracle, DB2, MySQL, PostgreSQL, and SQLite. SQLAlchemy has become increasingly popular since its release, but it still lacks good offline documentation. This practical book fills the gap, and because a developer wrote it, you get an objective look at SQLAlchemy's tools rather than an advocate's description of all the "cool" features. SQLAlchemy includes both a database server-independent SQL expression language and an object-relational mapper (ORM) that lets you map "plain old Python objects" (POPOs) to database tables without substantially changing your existing Python code. Essential SQLAlchemy demonstrates how to use the library to create a simple database application, walks you through simple queries, and explains how to use SQLAlchemy to connect to multiple databases simultaneously with the same Metadata. You also learn how to: Create custom types to be used in your schema, and when it's useful to use custom rather than built-in types Run queries, updates, and deletes with SQLAlchemy's SQL expression language Build an object mapper with SQLAlchemy, and understand the differences between this and active record patterns used in other ORMs Create objects, save them to a session, and flush them to the database Use SQLAlchemy to model object oriented inheritance Provide a declarative, active record pattern for use with SQLAlchemy using the Elixir extension Use the SQLSoup extension to provide an automatic metadata and object model based on database reflection In addition, you'll learn how and when to use other extensions to SQLAlchemy, including AssociationProxy, OrderingList, and more. Essential SQLAlchemy is the much-needed guide for every Python developer using this code library. Instead of a feature-by-feature documentation, this book takes an "essentials" approach that gives you exactly what you need to become productive with SQLAlchemy right away.
