ECPG is the standard, in the PostgreSQL database built-in, client programming interface for embedding SQL in programs written in the C programming language. [1] It provides the option for accessing the PostgreSQL database directly from the C code in the application, using SQL commands.
PostgreSQL can be expected to work on any of the following instruction set architectures (and operating systems): 64-bit x86-64 and 32-bit x86 on Windows and other operating systems; these are supported on other than Windows: 64-bit ARM [93] and the older 32-bit ARM, including older such as ARMv6 in Raspberry Pi [94]), RISC-V, z/Architecture, S ...
The database schema is the structure of a database described in a formal language supported typically by a relational database management system (RDBMS). The term " schema " refers to the organization of data as a blueprint of how the database is constructed (divided into database tables in the case of relational databases ).

Web frameworks like Django, Pylons, Pyramid, TurboGears, web2py, Tornado, Flask, Bottle, and Zope support developers in the design and maintenance of complex applications. Pyjs and IronPython can be used to develop the client-side of Ajax-based applications. SQLAlchemy can be used as a data mapper to a relational database.
A document-oriented database is a specialized key-value store, which itself is another NoSQL database category. In a simple key-value store, the document content is opaque. A document-oriented database provides APIs or a query/update language that exposes the ability to query or update based on the internal structure in the document. This ...
MongoDB uses JSON-like data for its document-oriented database. Some relational databases, such as PostgreSQL and MySQL, have added support for native JSON data types. This allows developers to store JSON data directly in a relational database without having to convert it to another data format.
