Butler SQL
{{Notability, Products, date=February 2023 Butler SQL is a now-defunct SQL-based database server for the classic Mac OS from EveryWare Development. For much of its history, it was partnered with another EveryWare product, Tango, that built dynamic database pages from SQL data. The product eventually ended up with Pervasive Software, although it is no longer sold. Butler was introduced to take advantage of new a Mac OS component known as the Data Access Manager (DAM), which was similar in concept to ODBC, allowing end-user client programs to access various data sources. DAM, however, worked at a lower level than ODBC and did not contain any inherent query language. To address the concern that a single DAM program might want to work with different back-end databases, Apple used a second system known as the Data Access Language (DAL), which was a variant of SQL that included additional flow-control and data manipulation instructions. DAL queries were converted to the target database u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Database Server
A database server is a server which uses a database application that provides database services to other computer programs or to computers, as defined by the client–server model. Database management systems (DBMSs) frequently provide database-server functionality, and some database management systems (such as MySQL) rely exclusively on the client–server model for database access (while others, like SQLite, are meant for use as an embedded database). Users access a database server either through a " front end" running on the user's computerwhich displays requested dataor through the " back end", which runs on the server and handles tasks such as data analysis and storage. In a master-slave model, database master servers are central and primary locations of data while database slave servers are synchronized backups of the master acting as proxies. Most database applications respond to a query language. Each database understands its query language and converts each submitted ...

Classic Mac OS
Mac OS (originally System Software; retronym: Classic Mac OS) is the series of operating systems developed for the Macintosh family of personal computers by Apple Computer from 1984 to 2001, starting with System 1 and ending with Mac OS 9. The Macintosh operating system is credited with having popularized the graphical user interface concept. It was included with every Macintosh that was sold during the era in which it was developed, and many updates to the system software were done in conjunction with the introduction of new Macintosh systems. Apple released the Macintosh 128K, original Macintosh on January 24, 1984. The System 1, first version of the system software, which had no official name, was partially based on the Lisa OS, which Apple previously released for the Apple Lisa, Lisa computer in 1983. As part of an agreement allowing Xerox to buy Share (finance), shares in Apple at a favorable price, it also used concepts from the Xerox PARC Xerox Alto, Alto computer, which ...

Data Access Manager
{{short description, Classic Mac OS API The Data Access Manager (DAM) was a database access API for the classic Mac OS, introduced in 1991 as an extension to System 7. Similar in concept to ODBC, DAM saw little use and was eventually dropped in the late 1990s. Only a handful of products ever used it, although it was used for some extremely impressive demoware in the early 1990s. More modern versions of the classic Mac OS, and macOS, use ODBC for this role instead. Concepts DAM and ODBC are similar in many ways. The primary purpose of both systems was to send "query strings" to a data provider, who would respond (potentially) with a "result set" consisting of rows of data. Both systems were expected to convert data to and from the system's respective formats, integers and strings for instance. Additionally, both provided a communications subsystem that hid the details of sending queries and data between the client and server. Like most Apple software, DAM attempted to make the query ...

ODBC
In computing, Open Database Connectivity (ODBC) is a standard application programming interface (API) for accessing database management systems (DBMS). The designers of ODBC aimed to make it independent of database systems and operating systems. An application written using ODBC can be ported to other platforms, both on the client and server side, with few changes to the data access code. ODBC accomplishes DBMS independence by using an ''ODBC driver'' as a translation layer between the application and the DBMS. The application uses ODBC functions through an ''ODBC driver manager'' with which it is linked, and the driver passes the query to the DBMS. An ODBC driver can be thought of as analogous to a printer driver or other driver, providing a standard set of functions for the application to use, and implementing DBMS-specific functionality. An application that can use ODBC is referred to as "ODBC-compliant". Any ODBC-compliant application can access any DBMS for which a driver is ...

Data Access Language
Data Access Language for the Macintosh, or simply DAL, was a SQL-like language and application programming interface released by Apple Computer in 1990 to provide unified client/server access to database management systems. It was known for poor performance and high costs, something Apple did little to address over its short lifetime, before it was sold off in 1994. DAL is used as the native SQL dialect of the PrimeBase SQL server, as well as the now-defunct Butler SQL. History DAL started as a 3rd-party product, CL/1 (''Connectivity Language One''), from a small vendor, Network Innovations. Apple purchased the company in 1988, during a time that client/server databases were becoming a hot issue in the industry. They released their first version of the re-branded software in 1989, for MVS, and followed with other versions over the next year or so. DAL suffered from most Apple problems of the early 1990s, notably an alternating level of support in which Apple would aggressivel ...

Discontinued Software
Abandonware is a product, typically software, ignored by its owner and manufacturer, and for which no official support is available. Within an intellectual rights contextual background, abandonware is a software (or hardware) sub-case of the general concept of ''orphan works''. Museums and various organizations dedicated to preserving this software continue to provide legal access. The term "abandonware" is broad, and encompasses many types of old software. Definitions of "abandoned" vary, but in general it is like any item that is abandoned – it is ignored by the owner, and as such product support and possibly copyright enforcement are also "abandoned". Types ;Commercial software unsupported but still owned by a viable company: The availability of the software depends on the company's attitude toward the software. In many cases, the company which owns the software rights may not be that which originated it, or may not recognize their ownership. Some companies, such as Bor ...

Classic Mac OS Software
A classic is an outstanding example of a particular style; something of lasting worth or with a timeless quality; of the first or highest quality, class, or rank – something that exemplifies its class. The word can be an adjective (a ''classic'' car) or a noun (a ''classic'' of English literature). It denotes a particular quality in art, architecture, literature, design, technology, or other cultural artifacts. In commerce, products are named 'classic' to denote a long-standing popular version or model, to distinguish it from a newer variety. ''Classic'' is used to describe many major, long-standing sporting events. Colloquially, an everyday occurrence (e.g. a joke or mishap) may be described in some dialects of English as 'an absolute classic'. "Classic" should not be confused with ''classical'', which refers specifically to certain cultural styles, especially in music and architecture: styles generally taking inspiration from the Classical tradition, hence classicism. ...
