M Computer Database Language
The M database is a hierarchical key-value store designed for high-throughput transaction processing. Intersystems has some products which are a super-set of the M programming language. Iris Description Page Cache Description Page To install an M interpreter database on your computer, try a YottaDB Docker image. YottaDB and its
An ANSI standard computer language, M isolates VISTA Applications from the underlying hardware platform, providing real-world portability. Because of M portability over the decades, VISTA has easily migrated from 1970's minicomputers to today's high-performance servers. Note M is an alternate name for MUMPS. When you read about M or MUMPS in
Power Query M, a language commonly referred to as quotM,quot is a powerful data transformation and data preparation language designed specifically for Microsoft's Power Query, an ETL Extract, Transform, Load tool integrated into the Power BI, Excel, and other Microsoft products.
This is where M comes in. Microsoft is betting that tools have improved to the point where it's now possible to model things more directly. They've obviously learned from the mistakes of others, since M is a textual language rather than the slick boxes-and-arrows language of earlier visual modeling tools. Think of M as another version of UML
MUMPS quotMassachusetts General Hospital Utility Multi-Programming Systemquot, or M, is an imperative, high-level programming language with an integrated transaction processing key-value database.It was originally developed at Massachusetts General Hospital for managing patient medical records and hospital laboratory information systems.. MUMPS technology has since expanded as the predominant
Power Query M formula language. Microsoft Power Query provides a powerful data import experience that encompasses many features. Power Query works with desktop Analysis Services, Excel, and Power BI workbooks, in addition to many online services, such as Fabric, Power BI service, Power Apps, Microsoft 365 Customer Insights, and more.
M labelrefs are a subset of entryrefs that exclude offsets and separate indirection. Labelrefs are used with parameter passing. Indirection M provides indirection as a means to defer definition of elements of the code until run-time. Indirection names a variable that holds or quotpointsquot to the element. The indirection operator is the quotatquot symbol .
The M evaluator abides by the dependency ordering provided by expressions, but is free to perform the remaining calculations in any order it chooses. For example, the computation order could be such as the current time or the results of a query against a database that evolves over time, rendering them non-deterministic. While functions
M is the powerful language behind the scene of Power Query. Any transformation you apply will be written in M language. For many, M looks like a scary language. In this post I like to explain a bit of basics of M. Not mentioning any functions. Mainly I want to explain to you how the M language syntax is structured.
M is a reliable quotschemalessquot or quotNoSQLquot database system, conceptually similar to Amazon SimpleDB and Google BigTable, but with the advantage of a much longer, time-tested track record of success. The Language The M programming language is a structured, imperative programming language with powerful introspection and indirection facilities.
