Econometric Modeling Software (EMS) EMS is Economic Sciences Corporation's high performance, fourth generation language containing comprehensive facilities for: Application Development Database Management Reporting Analysis Graphical Display It is a powerful tool, yet easy to use and will support all corporate applications -- small and large, simple and complex. The developers of EMS recognize that, in the real world, most corporate data is related in one way or another to time. Transactions, and therefore data records, are associated with specific dates. Accounting and Financial Data Customer Data Financial Instruments Stocks Bonds -- Purchase date, maturity date, current price Interest Earned -- over some time period Management Information Summary of Transactions Income EMS is uniquely structured to store data in relation to time, permitting the manipulation, consolidation, storage, and retrieval of time-dependent data while automatically and correctly aligning all data values. It eliminates the drudgery and complexity of programming a date orientation from scratch for each application. EMS's time/date facilities are the most powerful and comprehensive available in any fourth generation language. EMS's built-in database management system fully supports hierarchical, relational, and network data structures, yet Economic Sciences Corporation has moved beyond, to the next advance -- recognizing and capitalizing on the time relation of business data. Database Management EMS's built-in database management capability allows physical and logical data structures to be entirely independent. Hierarchical, relational, and network data structures are fully supported. EMS provides on of the most complete and efficient model inversion capabilities available today. An unlimited number of differing user views are permitted for a single database. These views can be stored in the referenced database or independently. Once a user view is formed, it can be manipulated without further reference to either the database index or the underlying data records themselves. The EMS database management system permits effective control over the factors which affect machine efficiency, including physical and logical data structures, record access menthols, and the use of computer memory and buffers. Powerful Report Writer The EMS Report Writer is the most flexible and comprehensive reporting tool of its kind. It has logical standard settings which permit the easy production of basic reports. Every aspect of report formatting and layout can be changed to allow the most exacting requirements to be met. Single Level Command Environment for Application Development EMS's single level command environment contains specialized commands for application development. These include commands for user inquiry and response prompting, including full-screen facilities, comprehensive error checking, complete terminal input/output control, powerful programming control structures, including DO ...WHILE, REPEAT...Until, IF...THEN...ELSE, and SELECT ...WHEN, numeric and alphanumeric string manipulation, and batch processing. EMS command files, as program instruction files are named, can call other command files to any level of depth, thereby permitting program modularity. Pre-Programmed Functions EMS has hundreds of pre-programmed functions. These include functions for arithmetic and financial computations, data record manipulation, including set theory operations, and programming functions which utilize internal system information to allow virtually any operation to be conducted under program control. Analysis Tools EMS contains a complete selection of analysis techniques, including regression and econometric analysis, financial modeling, and statistical tools. In addition, any data can be downloaded in Microsoft Excel and Lotus 1-2-3 spreadsheet formats. Ease of Use EMS is exceptionally user friendly. Problem resolution is greatly simplified, since EMS prints one of over 2500 specific English error messages when a problem is detected. When possible, EMS prompts for missing information. The EMS syntax is very flexible, with only a few simple rules which are recognized consistently throughout the language. Data Security Data security for the information in your database is provided by an elaborate security mechanism. In addition to general computer logon passwords and passwords for each EMS database or database partition, up to 253 data security classes can be established to protect data to any level of specificity. Availability EMS is available under IBM's VM/CMS operating system and can be installed on the IBM PC Server 500 System/390, the new IBM R/390, and all IBM mainframes and compatible processors. VM/CMS is an ideal operating environment for interactive computing. EMS has been specifically optimized to take advantage of VM's highly advanced memory, disk management, and terminal control capabilities. VM/CMS is both extremely powerful and flexible, yet easy to maintain. To order or for more information, send e-mail to: sales@econsci.com Economic Sciences Corporation
