Real-time Programming Language
Real-time Programming Language (RPL) is a compiled database programming language used on CMC/Microdata/McDonnell Douglas REALITY databases, derived and expanded from the PROC procedure language, with much extra functionality added. It was originally developed under the name "PORC" by John Timmons and Paul Desjardins in about 1975. "PORC" was then further developed by Tim Holland under the employ of George Ridgway's company Systems Management, Inc. (SMI) in Chicago. A number of large scale manufacturing applications were developed in RPL, including that which was in use at Plessey and GEC-Plessey Telecommunications limited in Liverpool Liverpool is a city and metropolitan borough in Merseyside, England.

Multidimensional Database
Online analytical processing, or OLAP (), is an approach to answer multi-dimensional analytical (MDA) queries swiftly in computing. OLAP is part of the broader category of business intelligence, which also encompasses relational databases, report writing and data mining. Typical applications of OLAP include business reporting for sales, marketing, management reporting, business process management (BPM), budgeting and forecasting, forecasting, financial reporting and similar areas, with new applications emerging, such as agriculture. The term ''OLAP'' was created as a slight modification of the traditional database term online transaction processing (OLTP). OLAP tools enable users to analyze multidimensional data interactively from multiple perspectives. OLAP consists of three basic analytical operations: consolidation (roll-up), drill-down, and slicing and dicing.O'Brien, J. A., & Marakas, G. M. (2009). Management information systems (9th ed.).
