Application Integration Architecture. In computing, Application Integration Architecture ( AIA) is an integration framework produced by Oracle Corporation . Standards-based, AIA has pre-built common object definitions and services. Oracle AIA is built on Oracle Fusion Middleware's SOA and Business Process-Management (BPM) products.
Data integration involves combining data residing in different sources and providing users with a unified view of them. [1] This process becomes significant in a variety of situations, which include both commercial (such as when two similar companies need to merge their databases) and scientific (combining research results from different bioinformatics repositories, for example) domains.
PL/SQL includes procedural language elements such as conditions and loops, and can handle exceptions (run-time errors). It allows declaration of constants and variables, procedures, functions, packages, types and variables of those types, and triggers. Arrays are supported involving the use of PL/SQL collections.

Hierarchical and recursive queries in SQL. A hierarchical query is a type of SQL query that handles hierarchical model data. They are special cases of more general recursive fixpoint queries, which compute transitive closures . In standard SQL:1999 hierarchical queries are implemented by way of recursive common table expressions (CTEs).
An entity–attribute–value model ( EAV) is a data model optimized for the space-efficient storage of sparse—or ad-hoc —property or data values, intended for situations where runtime usage patterns are arbitrary, subject to user variation, or otherwise unforeseeable using a fixed design. The use-case targets applications which offer a ...
First normal form ( 1NF) is a property of a relation in a relational database. A relation is in first normal form if and only if no attribute domain has relations as elements. [1] Or more informally, that no table column can have tables as values. Database normalization is the process of representing a database in terms of relations in standard ...
Accounting. An accounting information system (AIS) is a system of collecting, storing and processing financial and accounting data that are used by decision makers.
