Prior to version 7.0, CSPro only processed data files that were represented as ASCII and later UTF-8
text files. In addition to the main text data file, CSEntry would create additional files to store information such as the notes, partial save statuses, and other case metadata. To support more dynamic data entry possibilities, there are now multiple data sources to which data can be entered and from which data can be read.
CSPro DB is now the default type for newly created data files, and future CSPro features may only be added for the CSPro DB type. When a file exists, CSPro attempts to determine what kind of file it is and then opens it with the appropriate data source handler.
There are three types of data sources:
The text data source is what was always used in CSPro prior to version 7.0. Cases are stored as text in UTF-8 format. Supporting text data sources allows CSPro to maintain backwards compatibility with existing data files. Text data sources can use any file extension with the exception of .csdb. If other programs directly use the CSPro data file (as opposed to using exported data), you may still want to use a text data source as other programs will not be able to read a CSPro DB file.
The CSPro DB data source is the default type used for newly created data entry files. Files created using this type have the extension .csdb and are not text files so they cannot be viewed in Text Viewer
. All information about a case is stored in this file, including the case contents, case labels, notes, partial save statuses, verification information, revision history, and a copy of the dictionary. The CSPro DB data source simplifies data collection, particularly if conducting a CAPI survey, as all information about cases is stored in a single place and the revision history allows CSPro, when syncing data
, to only sync data that has changed.
If you use the CSPro DB type, then the data you collect cannot be directly used with previous versions of CSPro or tools that process text files. You can use the Data Viewer
tool to convert data from the CSPro DB type to text and vice versa in case you need to use a previous version of CSPro or a preexisting tool that only works with text files.
The none data source is not associated with a file and allows you to run programs without needing to associate a dictionary with a file, usually with the assumption that the file association will be determined during the program and assigned using the setfile
function. Adding cases to a none data source will result in nothing happening and any attempt to load or write cases to the file will appear successful but nothing will happen. This data source is useful for menu programs or instances when you do not initially know what an external dictionary should be set to.
