Comments.

Original view. New, more simple and effective way to present the already known operations and functions, the way which raises the interface friendliness but do not provide new analytical capabilities.

Original solution! New technological solution with using of the already known operations and functions which raises the interface friendliness and provide new analytical capabilities.

In DALSolution only! Absolutely original operations and functions which are used in DALSolution only.

Constructing Dictionaries of Variables. Original Solution!

DALSolution Dictionaries use the variables of the Text (Alternative and Non-Alternative), Number and Date types.

Create and correct the Dictionaries of Variables

Support for operations with variables of the Text/Alternative type

Support for operations with variables of the Text/Non-Alternative (multiple response) type

Support for operations with variables of the Number type

Support for operations with variables of the Date type

Reorder and recode the variables

Sort text variables values

Recode text variables values

Export Dictionaries of variables to a file

Dictionaries of variables export-import

Change type of the variables already existing in the Dictionary

Operate with non-alternative (multiple response) variables

Construct secondary variables

Manual data entry. Original Solution!

Manual data entry in standard and fast modes

Control data entry correctness

Manual data entry in a specified context (subset)

Entered data correction

New data addition during analysis

Data exchange

Export and read (import) data in text formats (Windows ANSI, DOS or OS/2(PC-8))

Reads and writes SPSS files

Export and import data in MS Access 2.0, 7.0, 8.0 formats

Export and import MS Excel files via ODBC

Read and write SPSS files

Read and write data matrices

Import data from dBASE, FoxPro, Paradox via ODBC

Original Solution! Support operations with Dictionaries of variables while export-import procedures

Constructing secondary variables. Original Solution!

Special Constructor provides to create new features and variables. Constructor solves the problems of new feature construction in conditions when such methods as cluster analysis, taxonomy analysis, image recognition and automatic classifications are not effective.

Constructing contexts (subsets, subsamples). Original Solution!

Construct contexts

Automatic contexts saving

Select contexts from the Contexts List

Preview tables and charts in different contexts

Original FormuLanguage for contexts construction

Analysis of rules. In DALSolution only!

The data analysis method known as Determinacy Analysis (or DA), serves to analyze the influence of some factors (features) on anothers. The Method gives the systematic solution for the problems of statistical relations analysis between the features in conditions when regression analysis, dispersion analysis, discriminant analysis, factor analysis, log-linear analysis, chi-square, correlations and covariations coefficients and others are not effective.
