What is the difference between MDX and MDX a-spec?
MDX is the established language for querying multidimensional data in OLAP systems, while “MDX a-spec” is not a universally recognized standard and often points to vendor-specific variants, drafts, or mislabeling in documentation. In practice, the difference hinges on which engine or project is being referenced and how that implementation extends or interprets MDX.
What is MDX?
MDX stands for Multidimensional Expressions. It is the query language designed to interrogate multidimensional data stored in OLAP cubes, enabling analysts to slice, dice, and aggregate across multiple dimensions. There is no single globally adopted modern MDX standard that all engines follow in lockstep; instead, the language is defined by the implementations provided by major vendors and open-source projects, with some variations in features and syntax.
Key concepts you typically work with in MDX include:
- Axes, primarily COLUMNS and ROWS, with optional PAGES/SLICER to filter data.
- Members, tuples, and sets to select elements from dimensions.
- Measures and calculated members to produce numeric results and on-the-fly calculations.
- A library of functions for navigation, time intelligence, filtering, and aggregation across hierarchies.
In practice, MDX is used in BI tools and OLAP servers such as Microsoft SQL Server Analysis Services, Mondrian, Apache Kylin, and other engines to craft pivot-like queries, custom calculations, and cross-tab reports.
What MDX a-spec could refer to
There is no widely recognized standard named “MDX a-spec.” When you encounter the phrase, it is usually one of several possibilities:
- An abbreviation in vendor-specific documentation for an MDX variant that adds extensions or altered syntax.
- A draft, internal, or project-specific specification labeled as “a-spec” or “abstract-spec,” indicating an early or non-official version.
- A mislabeling or shorthand for referring to MDX-related specifications, tools, or libraries that parse or generate MDX queries.
- A confusion with related terms (for example, a vendor’s MDX dialect) that is not part of a formal, universally adopted standard.
Because MDX is implemented across many platforms—SSAS, Mondrian, Apache Kylin, and other OLAP engines—the exact features and syntax can vary. If you see “MDX a-spec” in documentation, check the source context or contact the vendor or project maintainers to clarify which dialect, version, and extensions are being referenced.
Practical guidance for handling MDX references
Encountering the term MDX a-spec in documentation or code calls for careful verification. Here’s how to approach it:
- Identify the target engine or product cited (for example, SSAS, Mondrian, or an in-house analytics platform) and consult its official MDX reference for exact syntax and supported features.
- Look for notes about extensions or dialect differences that might align with a non-standard “a-spec” terminology.
- Test representative MDX queries in the actual environment to see which elements (functions, axes, or syntax) are supported.
- Ask the documentation authors or the project team for a precise definition of “a-spec,” including version numbers and any extensions involved.
Clarity on this point helps ensure that analysts author portable queries and that dashboards behave consistently across environments.
Summary
MDX is the established language for querying multidimensional data in OLAP systems, with a flexible set of constructs for axes, sets, and calculations. The term “MDX a-spec” does not correspond to a single, widely recognized standard and is typically a vendor-specific extension, an informal draft, or a mislabeling. Always verify the exact dialect and version with the engine’s official documentation and test queries in the target environment to avoid confusion.
