In software, a data access object (DAO) is a pattern that provides an abstract interface to some type of database or other persistence mechanism. By mapping application calls to the persistence layer, the DAO provides data operations without exposing database details. This isolation supports the single responsibility principle.
Data-centric programming language defines a category of programming languages where the primary function is the management and manipulation of data. A data-centric programming language includes built-in processing primitives for accessing data stored in sets, tables, lists, and other data structures and databases, and for specific manipulation and transformation of data required by a ...
Scaffolding is a technique supported by some model–view–controller frameworks, in which the programmer can specify how the application database may be used.The compiler or framework uses this specification, together with pre-defined code templates, to generate the final code that the application can use to create, read, update and delete database entries, effectively treating the templates ...
The Qi4j programming environment offers a way to express Role method injection into Java objects. [8] Java 8 default method on interfaces can be used to implement Roles in a typesafe way. In the above money transfer use case, for example, the Role methods in the SourceAccount and DestinationAccount enact the actual transfer.
Development with db4o database does not require a separate data model creation, the application's class model defines the structure of the data. db4o attempts to avoid the object/relational impedance mismatch by eliminating the relational layer from a software project. db4o is written in Java and .NET and provides the respective APIs. It can ...
Apache Cassandra is a free and open-source database management system designed to handle large volumes of data across multiple commodity servers.The system prioritizes availability and scalability over consistency, making it particularly suited for systems with high write throughput requirements due to its LSM tree indexing storage layer.

Harbour is a computer programming language, primarily used to create database/business programs. It is a modernised, open source and cross-platform version of the older Clipper system, which in turn developed from the dBase database market of the 1980s and 1990s.
IBM VisualAge Java is an example of an integrated development environment implementing SCID features. A more recent example of Source Code in Database is CodeOntology, an open source tool and RDF database of Java source code that supports advanced SPARQL queries, such as Select recursive methods or Select methods that compute the cube root of a double.
