History[edit]

Usage of the 'alpha/beta' test terminology originated at IBM. Similar terminologies for IBM's software development were used by people involved with IBM from at least the 1950s (and probably earlier). 'A' test was the verification of a new product before the public announcement. 'B' test was the verification before releasing the product to be manufactured. 'C' test was the final test before the general availability of the product. As software became a significant part of IBM's offerings, the alpha test terminology was used to denote the pre-announcement test and the beta test was used to show product readiness for general availability. Martin Belsky, a manager on some of IBM's earlier software projects claimed to have invented the terminology. IBM dropped the alpha/beta terminology during the 1960s, but by then it had received fairly wide notice. The usage of 'beta test' to refer to testing done by customers was not done in IBM. Rather, IBM used the term 'field test'.

Stages of development[edit]

Pre-alpha[edit]

Pre-alpha refers to all activities performed during the software project before formal testing. These activities can include requirements analysis, software design, software development, and unit testing. In typical open source development, there are several types of pre-alpha versions. Milestone versions include specific sets of functions and are released as soon as the feature is complete.

Alpha[edit]

The alpha phase of the release life cycle is the first phase to begin software testing (alpha is the first letter of the Greek alphabet, used as the number 1). In this phase, developers generally test the software using white-box techniques. Additional validation is then performed using black-box or gray-box techniques, by another testing team. Moving to black-box testing inside the organization is known as alpha release.^{[1][better source needed]}

Alpha software is software that is not thoroughly tested by the developer before it is released to customers. Alpha software usually contains serious errors;^[2] therefore it can be unstable and could cause crashes or data loss. Alpha software may not contain all of the features that are planned for the final version.^[3] In general, external availability of alpha software is uncommon in proprietary software, while open source software often has publicly available alpha versions. The alpha phase usually ends with a feature freeze, indicating that no more features will be added to the software. At this time, the software is said to be feature complete. A beta test is carried out following acceptance testing at the supplier's site (alpha test) and immediately prior to general release of the software as a product.^[4]

Beta[edit]

Beta, named after the second letter of the Greek alphabet, is the software development phase following alpha. Software in the beta stage is also known as betaware.^[5] Beta phase generally begins when the software is feature complete but likely to contain a number of known or unknown bugs.^[6] Software in the beta phase will generally have many more bugs in it than completed software, speed or performance issues, and may still cause crashes or data loss. The focus of beta testing is reducing impacts to users, often incorporating usability testing. The process of delivering a beta version to the users is called beta release and this is typically the first time that the software is available outside of the organization that developed it. Software beta releases can either be public or private, depending on whether they are openly available or only available to a limited audience. Beta version software is often useful for demonstrations and previews within an organization and to prospective customers. Some developers refer to this stage as a preview, preview release, prototype, technical preview / technology preview (TP),^[7] or early access.

Beta testers are people who actively report issues of beta software. They are usually customers or representatives of prospective customers of the organization that develops the software. Beta testers tend to volunteer their services free of charge but often receive versions of the product they test, discounts on the release version, or other incentives.

Perpetual beta[edit]

Some software is kept in perpetual beta, where new features are continually added to the software without establishing a final 'stable' release.

As the Internet has facilitated rapid and inexpensive distribution of software, companies have begun to take a looser approach to use of the word 'beta'.^[8] In February 2005, ZDNet published an article^[9] about the recent phenomenon of a beta version often staying for years and being used as if it were in production level, disparagingly called 'perpetual beta'. It noted that Gmail and Google News, for example, had been in beta for a long time although widely used; Google News did leave beta in January 2006, followed by Google Apps, including Gmail, in July 2009.^[10] This technique may allow a developer to delay offering full support and responsibility for remaining issues. In the context of Web 2.0, people even talk of perpetual betas to signify that some software is meant to stay in beta state. Also, 'beta' is sometimes used to indicate something more like a release candidate, or as a form of time-limited demo, or marketing technique.^[11] Since the introduction of Windows 8, Microsoft has called pre-release software as a 'preview', rather than beta. All pre-release builds released through the Windows Insider Program launched in 2014 are termed 'Insider Preview builds'.

Open and closed beta[edit]

Developers may release either a closed beta also called private beta, or an open beta also called public beta; closed beta versions are released to a restricted group of individuals for a user test by invitation, while open beta testers are from a larger group, or anyone interested. Private beta could be suitable for the software that is capable to deliver value, but is not ready to be used by everyone either due to scaling issues, lack of documentation or still missing vital features. The testers report any bugs that they find, and sometimes suggest additional features they think should be available in the final version. Examples of a major public beta test include the following:

• Early customers purchased a 'pioneer edition' of the WordVision word processor for the IBM PC for $49.95. In 1984, Stephen Manes wrote that 'in a brilliant marketing coup, Bruce and James Program Publishers managed to get people to pay for the privilege of testing the product.'^[12]
• In September 2000 a boxed version of Apple's Mac OS X Public Beta operating system was released.^[13]
• Microsoft's release of community technology previews (CTPs) for Windows Vista, between September 2005 and May 2006.^[14]
• From 2009 to 2011, Minecraft was in public beta.
• From December 29, 2014, all owners of Halo: The Master Chief Collection for the Xbox One were able to download and play the Beta of Halo 5: Guardians free of charge until January 18, 2015. Users of the Beta were reminded via an in-game popup that the release was a Beta and could contain some glitches, and were encouraged to communicate them through the Halo series online community.

Open betas serve the dual purpose of demonstrating a product to potential consumers, and testing among an extremely wide user base likely to bring to light obscure errors that a much smaller testing team might not find.

Release candidate[edit]

A release candidate (RC), also known as 'going silver', is a beta version with potential to be a final product, which is ready to release unless significant bugs emerge. In this stage of product stabilization, all product features have been designed, coded and tested through one or more beta cycles with no known showstopper-class bugs. A release is called code complete when the development team agrees that no entirely new source code will be added to this release. There could still be source code changes to fix defects, changes to documentation and data files, and peripheral code for test cases or utilities. Beta testers, if privately selected, will often be credited for using the release candidate as though it were a finished product. Beta testing is conducted in a client's or customer's location and to test the software from a user's perspective.

Release[edit]

Once released, the software is generally known as a 'stable release'. The formal term often depends on the method of release: physical media, online release or a web application.

Release to manufacturing (RTM)[edit]

The term release to manufacturing (RTM), also known as 'going gold', is a term used when a software product is ready to be delivered. This build may be digitally signed, allowing the end user to verify the integrity and authenticity of the software purchase. A copy of the RTM build known as the 'gold master' or GM is sent for mass duplication if applicable. RTM precedes general availability (GA) when the product is released to the public.

It is typically used in certain retail mass-production software contexts—as opposed to a specialized software production or project in a commercial or government production and distribution—where the software is sold as part of a bundle in a related computer hardware sale and typically where the software and related hardware is ultimately to be available and sold on mass/public basis at retail stores to indicate that the software has met a defined quality level and is ready for mass retail distribution. RTM could also mean in other contexts that the software has been delivered or released to a client or customer for installation or distribution to the related hardware end user computers or machines. The term does not define the delivery mechanism or volume; it only states that the quality is sufficient for mass distribution. The deliverable from the engineering organization is frequently in the form of a golden master media used for duplication or to produce the image for the web.

General availability (GA)[edit]

Army Gold Master Software List

General availability (GA) is the marketing stage at which all necessary commercialization activities have been completed and a software product is available for purchase, depending, however, on language, region, electronic vs. media availability.^[15] Commercialization activities could include security and compliance tests, as well as localization and worldwide availability. The time between RTM and GA can be from a week to months in some cases before a generally available release can be declared because of the time needed to complete all commercialization activities required by GA. At this stage, the software has 'gone live'.

Release to web (RTW)[edit]

Release to the web (RTW) or web release is a means of software delivery that utilizes the Internet for distribution. No physical media are produced in this type of release mechanism by the manufacturer. Web releases are becoming more common as Internet usage grows.

Support[edit]

During its supported lifetime, software is sometimes subjected to service releases, patches or service packs, sometimes also called 'interim releases' or 'maintenance release' (MR). For example, Microsoft released three major service packs for the 32-bit editions of Windows XP and two service packs for the 64-bit editions. Such service releases contain a collection of updates, fixes, and enhancements, delivered in the form of a single installable package. They may also implement new features. Some software is released with the expectation of regular support. Classes of software that generally involve protracted support as the norm include anti-virus suites and massively multiplayer online games. A good example of a game that utilizes this process is Minecraft, an indie game developed by Mojang, which features regular 'updates' featuring new content and bug fixes.

End-of-life [edit]

When software is no longer sold or supported, the product is said to have reached end-of-life, to be discontinued, retired, deprecated, abandoned, or obsolete, but user loyalty may continue its existence for some time, even long after its platform is obsolete—e.g., the Atari ST and Sinclair ZX Spectrum.

After the end-of-life date, the developer will usually not implement any new features, fix existing defects, bugs or vulnerabilities (known before that date or not) or provide any support for the product.

In information systems design and theory, single source of truth (SSOT) is the practice of structuring information models and associated data schema such that every data element is mastered (or edited) in only one place. Any possible linkages to this data element (possibly in other areas of the relational schema or even in distant federated databases) are by reference only. Because all other locations of the data just refer back to the primary 'source of truth' location, updates to the data element in the primary location propagate to the entire system without the possibility of a duplicate value somewhere being forgotten.

Deployment of an SSOT architecture is becoming increasingly important in enterprise settings where incorrectly linked duplicate or de-normalized data elements (a direct consequence of intentional or unintentional denormalization of any explicit data model) pose a risk for retrieval of outdated, and therefore incorrect, information. A common example would be the electronic health record, where it is imperative to accurately validate patient identity against a single referential repository, which serves as the SSOT. Duplicate representations of data within the enterprise would be implemented by the use of pointers rather than duplicate database tables, rows, or cells. This ensures that data updates to elements in the authoritative location are comprehensively distributed to all federated database constituencies in the larger overall enterprise architecture.^{[citation needed]}

SSOT systems provide data that are authentic, relevant, and referable.^[1]

• 1Implementation

Implementation[edit]

The 'ideal' implementation of SSOT as described above is rarely possible in most enterprises. This is because many organisations have multiple information systems, each of which needs access to data relating to the same entities (e.g., customer). Often these systems are purchased 'off-the-shelf' from vendors and cannot be modified in non-trivial ways. Each of these various systems therefore needs to store its own version of common data or entities, and therefore each system must retain its own copy of a record (hence immediately violating the SSOT approach defined above). For example, an ERP (enterprise resource planning) system (such as SAP or Oracle e-Business Suite) may store a customer record; the CRM (customer relationship management) system also needs a copy of the customer record (or part of it) and the warehouse dispatch system might also need a copy of some or all of the customer data (e.g., shipping address). In cases where vendors do not support such modifications, it is not always possible to replace these records with pointers to the SSOT.

For organisations (with more than one information system) wishing to implement a Single Source of Truth (without modifying all but one master system to store pointers to other systems for all entities), three supporting technologies are commonly used:^{[citation needed]}

• Enterprise service bus (ESB)
• Master data management (MDM)
• Data warehouse (DW)

Enterprise service bus (ESB)[edit]

An enterprise service bus (ESB) allows any number of systems in an organisation to receive updates of data that has changed in another system. To implement a Single Source of Truth, a single source system of correct data for any entity must be identified. Changes to this entity (creates, updates, and deletes) are then published via the ESB; other systems which need to retain a copy of that data subscribe to this update, and update their own records accordingly. For any given entity, the master source must be identified (sometimes called the Golden Record). Any given system could publish (be the source of truth for) information on a particular entity (e.g., customer) and also subscribe to updates from another system for information on some other entity (e.g., product).^{[citation needed]}

An alternative approach is point-to-point data updates, but these become exponentially more expensive to maintain as the number of systems increases, and this approach is increasingly out of favour as an IT architecture.^{[citation needed]}

Master data management (MDM)[edit]

An MDM system can act as the source of truth for any given entity that might not necessarily have an alternative 'source of truth' in another system. Typically the MDM acts as a hub for multiple systems, many of which could allow (be the source of truth for) updates to different aspects of information on a given entity. For example, the CRM system may be the 'source of truth' for most aspects of the customer, and is updated by a call centre operator. However, a customer may (for example) also update their address via a customer service web site, with a different back-end database from the CRM system. The MDM application receives updates from multiple sources, acts as a broker to determine which updates are to be regarded as authoritative (the Golden Record) and then syndicates this updated data to all subscribing systems. The MDM application normally requires an ESB to syndicate its data to multiple subscribing systems.^[2]Customer Data Integration (CDI), as a common application of Master Data Management, is sometimes abbreviated CDI-MDM.^{[citation needed]}

Data warehouse (DW)[edit]

Army Gold Master Software List

While the primary purpose of a data warehouse is to support reporting and analysis of data that has been combined from multiple sources, the fact that such data has been combined (according to business logic embedded in the data transformation and integration processes) means that the data warehouse is often used as a de facto SSOT. Generally, however, the data available from the data warehouse are not used to update other systems; rather the DW becomes the 'single source of truth' for reporting to multiple stakeholders. In this context, the Data Warehouse is more correctly referred to as a 'single version of the truth' since other versions of the truth exist in its operational data sources (no data originates in the DW; it is simply a reporting mechanism for data loaded from operational systems).^{[citation needed]}

SOLID & Source Code[edit]

In software design, the same schema, business logic and other components are often repeated in multiple different contexts, while each version refers to itself as 'Source Code'. To address this problem, the concepts of SSOT can also be applied to software development principals using processes like recursive transcompiling to iteratively turn a single source of truth into many different kinds of source code, which will match each other structurally because they are all derived from the same SSOT.
