Data Applications

Data applications deal with the acquisition and manipulation of data, but do not have the capacity for any statistical analysis. Most of the data applications allow you to convert from one file type to another.

Current data applications available on lab computers (Windows only):

DBMSCopy and Compare

Please Note: DBMS/Copy and Compare is no longer being sold and not supported by any vendor. Use Stat Transfer first for any file conversions. DBMS/Copy and Compare is still useful for older (pre-2000) file type conversions.

Lab Version: v8.0.0A & v7.0.0 (both on all Windows based lab workstations)

DBMS/Copy is a general purpose conversion software. It translates and transfers data between over 70 different data management systems, spreadsheets, statistical software, ODBC, and other application packages. DBMS/Copy is a very useful program for converting data from one format, such as an Excel spreadsheet, to another format such as a Stata ".dta" file. It has an easy-to-use graphical interface and can convert among dozens of different file types.

DBMS/Compare is that it is a multiple file comparison, data audit and analysis program. The program can scan any directory tree (including an entire disk), grab a list of all the variables in all the data files from multiple file formats, build views showing all variables across all databases and all databases across all variables. From there you can get value lists across multiple databases and do record by record comparisons across any number of databases. All information can be saved to Excel, HTML and ASCII files.

Common file types:

File type (extension): DBMS/Copy pseudo-extension:
ASCII (dat) (*) ascii2
Excel 5 (xls) xls5
Excel 97/2000 (xls) xls7
Gauss (dat, dht) gauss
Limdep binary (sav) limsav
Limdep ASCII (dat) limdat
Stata v6 8 byte doubles (dta) stata6
Stata v6 4 byte doubles (dta) stata64
Stata v7 8 byte doubles (dta) stata7
Stata v7 4 byte doubles (dta) stata74
Stata SE 8 byte doubles (dta) statase
Stata SE 4 byte doubles (dta) statase4
SAS for Windows v6 (sd2) sd2
SAS for Windows v7 (sd7) sd7
SAS for Windows v8 (sas7bdat) sas7bdat
SAS for Unix v7/v8 (sas7bdat) sas7sun

(*) To read an ASCII file you will need the interactive session (in order to specify the file's structure). If you write a file as ASCII, DBMS will write it as a comma-delimited file with a first row of headers (variable names).


Lab Version: 11

Stat/Transfer is designed to simplify the transfer of statistical data between different programs.  Stat/Transfer will automatically read statistical data in the internal format of one of the supported programs and will then transfer as much of the information as is present and appropriate to the internal format of another.  Stat/Transfer preserves all of the precision in your data, while automatically minimizing the size of your output data set.  Stat/Transfer also allows control over the storage format of your output variables.  In addition to converting the formats of variables, Stat/Transfer also processes variable names, missing values and value and variable labels automatically.   Stat/Transfer allows you to select just the variables and cases you want to transfer.  In addition to the standard Windows interface, a command processor on Windows and Unix allows you to run a transfer in batch mode.  This makes it straightforward to set up fully automatic batch procedures for repetitive tasks.

Supported Formats

Stat/Transfer’s ODBC support allows you to also read and write to such relational databases as Oracle, Sybase, Informix, and DB/2.

TextPipe Pro

Lab Version: 7.8.11

TextPipe Pro is a text processing application that takes a group of files and applies a set of operations or filters to each file in turn. Each filter performs an operation such as a search and replace, adding text to the left margin, converting end of line characters etc, and then passes the result on to the next filter, just as though the entire file had been processed using that filter first. TextPipe Pro has an extensive range of over 100 filters for adding, deleting, replacing, sorting and transforming text. Common tasks like converting files between PC, Macintosh, Mainframe and Unix formats are well catered for. With TextPipe's command-line automation or COM interface, complex processing tasks can be performed without user intervention. Filters included can also split and join files, add line numbers, word wrap, convert between OEM and ANSI and remove duplicate lines/HTML/columns/binary characters/ANSI codes.

Web sites can be maintained easily with multi-file search and replace, and the ability to add standard text (such as copyright messages or banner advertising) to the start and end of each file. Multiple spaces and blank lines can be quickly removed to improve download times.

TextPipe Pro replaces a substantial set of smaller text utilities with a unified and easy-to-use GUI. General users, web authors, administrators and programmers can readily perform complex text-processing with a minimum of technical knowledge.

TextPipe Pro makes it fast and easy to convert, transform and re-purpose data in text files, including

  • HTML, XML and other structured documents from the WWW
  • Fixed length or delimited files (CSV, Tab, Pipe, etc)
  • Unix, Mainframe and PC/Windows end-of-line formats
  • Inside Zip files, and the new Microsoft Office 2007 formats DOCX, XLSX, PPTX
  • ASCII, ANSI, Unicode and EBCDIC files
  • Security log files from firewalls, web servers etc
  • EDIFACT, HL7, SWIFT and other structured formats
  • Spooled print files
  • Structured and unstructured reports of any size or dimension
