Whittington Idaho National Engineering Laboratory Special Applications Unit P.O. Box 1625, Idaho Falls ID 83415-1609 January 1, 1993 Abstract AdaSAGE is an application development tool for Ada programmers implemented as a set of Ada packages and a set of executable programs used as support utilities during application development and operation. Many questions have been asked regarding the characteristics of AdaSAGE (i.e. Is AdaSAGE relational?). Herein several such questions are posed and answered. AdaSAGE is an application development tool that provides facilities for creating an application specific relational data base. What is the purpose of AdaSAGE? ------------------------------- AdaSAGE was designed to provide tools and an environment for Ada programmers to develop major non-proprietary systems completely in Ada which are as good as or better than systems developed using alternate methods. Who uses AdaSAGE? ----------------- The SAGE system began at the INEL (Idaho National Engineering Laboratory) in 1982. In 1987, it was made available in the Ada programming language for use on U.S. Marine Corps projects. Since then, it has been used by all of the major services of the DOD (Department of Defense) and for system development within the DOE (Department of Energy). It has been made available through a variety of distribution channels to both government and private industry. Does AdaSAGE require a license? ------------------------------ AdaSAGE is a non-proprietary government domain product which does not require a license for development or application sites. It may be acquired from one of the following sources (a user group fee or handling fee may be required): AdaSAGE Users' Group -------------------- Idaho National Engineering Laboratory (208)526-0656 RAPID Center ------------ Sgt. Stephen St. Espirit (703)285-9007 Office Of Scientific Technology Information ------------------------------------------- P.O. Box 62 Oak Ridge, TN 37831 (615) 576-1166 Is AdaSAGE written in Ada? -------------------------- AdaSAGE reusable Ada packages are 100% Ada code. In the MS-DOS environment, approximately 5% of AdaSAGE is written in assembly language to provide optimal interface to low level hardware that is not readily available to MS-DOS. How extensive is AdaSAGE? ------------------------- During AdaSAGE development, extensive effort is expended to create application development tools and associated system development methodologies that maximizes the effectiveness and productivity of Ada system developers. The AdaSAGE system is comprised of over 300,000 lines of code representing over 250 person-years of effort with an average cyclomatic complexity of 4, as measured by a standard code metric analysis tool. Does AdaSAGE support the Open System Environment? ------------------------------------------------- The AdaSAGE development team is committed to supporting the Open System Environment standard. At the current time AdaSAGE provides support in the following ways: Ada AdaSage is written in Ada. SQL Interactive and imbedded SQL is provided. GKS Standard GKS is provided. POSIX AdaSAGE is available on POSIX systems. GOSIP AdaSAGE supports multi-user development on GOSIP networks On what platforms is AdaSAGE available? --------------------------------------- Versions of AdaSAGE tools and reusable packages are available within a variety of environments. AdaSAGE is now available or will be available soon on the following hardware platforms: Intel 8088 Intel 8086 Intel 80286 Real and Protected Mode Intel 80386 Real and Protected Mode Intel 80486 Real and Protected Mode AT&T 3B2 Sun SPARC RS/6000 AdaSAGE runs under the following operating systems: MS-DOS UNIX AIX The AdaSAGE application development system is available for the following Ada compilers: Alsys Meridian Verdix Is training and support available? ---------------------------------- Beginning, advanced and graphics training courses are available at the INEL or at a requested location if a sufficient number of students is available. The AdaSAGE Users' Group supports registered users with a technical support line, new release upgrades, a bulletin board, a newsletter and other training and assistance. For more information, contact the AdaSAGE Users' Group at (208)526-0656. Is AdaSAGE maintained? ---------------------- AdaSAGE is supported by the Idaho National Engineering Laboratory (a DOE laboratory) with funds supplied by the AJPO (Ada Joint Program Office) and other DOD agencies. A long term agreement is in place between the DOE and DOD for continual support in the future. Work is currently underway for conversion to other computer platforms, open system architecture adherence, and other areas. Does AdaSAGE have a Data Dictionary? ------------------------------------ A data dictionary contains the data structure (schema) and often other ancillary information about the data and its structure. AdaSAGE supports an independent data dictionary and a facility for defining, modifying, and reporting on this information. This capability allows many different applications to access the same data dictionary and provides physical and logical data independence as specified in rules 8 and 9 of Codd's Rules. What security support is included in AdaSAGE? --------------------------------------------- AdaSAGE provides many levels of security. Even though data integrity checks are a form of security and provided by AdaSAGE, they will not be discussed here. Access security is provided by password protection at the database, relation (flat file), and the individual attribute (column) level. These are defined within the data dictionary and enforced throughout the system for both programmers and users. Additional security is often required within applications. Many such applications have been provided using AdaSAGE with additional protection through user tables which contain user identification information, statistical information, and network and system information concerning user logon identifiers and privileges. Does AdaSAGE speak SQL? ----------------------- Speaking SQL usually refers to an RDBMS, AdaSAGE is not an RDBMS. AdaSAGE is an application development tool that provides facilities for creating an application specific relational data base. There are two aspects of SQL dialog to consider. First is listening to SQL and responding by executing the requested command. Second is issuing SQL to get a foreign system to execute some process on your behalf. In the first case AdaSAGE provides both an imbedded SQL technology and an interactive SQL system adapted to comply with ANSI-SQL DML Level 1. In the second case AdaSAGE does not provide any capabilities for creating SQL commands, but since AdaSAGE is a set of Ada packages there is no reason that a package could not be developed to do so. Does AdaSAGE support multiuser system development? -------------------------------------------------- AdaSAGE provides for both single user and multiuser systems. Both types of systems have been represented in fielded applications. A unique feature of the AdaSAGE multiuser system (MultSage) is the distribution of not only the data to be shared by many users, but also the distributed processing concept where each user contributes his CPU to the multiuser database management and locking functions. This concept is used for LAN (local area network) type applications. Are there audit trail and recoverability features in AdaSAGE? ------------------------------------------------------------- The capability to record all transactions and roll forward from previous dates gives an audit trail and recover capability. These features are often provided within data base management systems, and are provided with AdaSAGE as a logging option, but seldom if ever are they used in final applications because of the excessive time and data storage requirements. An application using AdaSAGE may be developed to provide full or partial capabilities in this area using the Ada language and AdaSAGE provided packages. More often, applications regularly backup or copy current data to another device to provide data recoverability. As well, AdaSAGE provides a facility to rebuild or recover current data base information in place. Will AdaSAGE interface to DBMS's? --------------------------------- Neither Codd's rules for a relational system nor ANSI SQL specifies the physical storage format of data. Logically, it must appear to be two dimensional and is often referred to as being composed of relations (or a less precise term, flat files). Each data base system, therefore, tends to have its own unique method of physical data storage. A method to move data between different systems is often required. There are some commonly used formats of files from which many DBMS's load and unload data. This is one method of interface between two DBMS's and is supported by AdaSAGE. With AdaSAGE, the Ada language may also be used to directly and much more quickly move data from a DBMS into an AdaSAGE relation or in the reverse direction. The only requirement is that the DBMS support an Ada interface. Is AdaSAGE a code generator? ---------------------------- Currently there are no components of the AdaSAGE system that generate code. The application paradigm supported by AdaSAGE results in applications that are data driven. This data is contained in a data dictionary containing information about the relational structure of the application's data, the application's user presentation and various other application specific information. Are AdaSAGE packages reusable? ------------------------------ AdaSAGE provides many Ada packages, all of which are reusable. Many of them are independent and may be used within any Ada system without causing the inclusion of the data base or user interface facilities. These include libraries for sorting, data movement, binary operations, bit manipulations, graphics, string manipulation, and others. There are also packages which directly access the data base system and others which access the user interface facilities. AdaSAGE adheres to the concept of "black box" modularity which emphasizes the reuse of code through data encapsulation and extensibility through inheritance. All of the provided Ada packages are designed to be understandable, useful and usable, and are loosely coupled and highly cohesive at their level of abstraction. Does AdaSAGE support graphics development? ------------------------------------------ AdaSAGE graphics support is available on some platforms. The graphics support includes the following: Low level support ANSI-GKS Level ma Intermediate level support Primitive Calls - Rotatable Arc, PolyLine, Rectangle, Rotatable, Scalable Text and Bit-Mapped Text Input Calls - Keyboard and Mouse System Calls Window Calls Device Calls Font Calls Locator Calls PCX Graphics File Calls High level support 2-D Graphing Package - Pie, Bar, X-Y, Area and Line Charts Graphical User Interface Package - Menu bar, Pull-down Menus and Pop-up Menus Data driven graphical reports edited in THOR Device support Video - CGA, EGA, VGA Printers - EPSON-FX, EPSON-LQ, HPCL, Postscript Mouse - Microsoft Mouse Driver Support Utilities Resource Compiler Stroke Font Editor Bit-Mapped Font Editor Cursor Editor ------------------------------ 5.
