About Powerbase
Powerbase can be used to create databases of information of almost any kind
and provides powerful facilities for maintaining such databases and for
selectively retrieving and printing information from them. Using Powerbase
at an elementary level is particularly easy - you can, for example, set up a
simple address-book database in a matter of minutes - yet the needs of more
advanced users have not been neglected. Descriptions of Powerbase from
various sources have sometimes implied that it is a relational database. It
isn't, but it can provide you with some of the facilities which fall outside
the sphere of a simple flat-file (card index) type of database and for
which a relational database program might otherwise be necessary.
It is best described as a flat-file database with table-validation. This
means that text fields within the database can be linked to a list of items
in such a way that the field will not accept items unless they are on the
list. That list (called a validation table) can have many additional columns
providing extra information which may be included in printed reports from
the database if required.
Other important features of Powerbase.
- Can handle very large databases on a hard disc. The largest we have heard of
has over 30,000 records.
- Multiple indexes to provide rapid data access. A database containing details
of books could be indexed by author, title and subject.
- Subsets of records can be exported as individual functioning databases.
- Fast searching for and retrieval of individual records.
- Linking to sprite, text, draw and other files external to the database.
- Powerful query language to select records for printing.
- Reports printed in several different formats, enhanced with colour if desired.
- Direct data-merging with Impression Style and Publisher and with recent versions of OvationPro.
- Script language to automate frequently carried-out tasks.
- Data can be output as CSV (comma-separated-values) files for importing into
other programs.
- Powerbase can import CSV files created in other environments and even create a working database directly from a CSV file which has a suitable header.
- Files stored anywhere on the computer (even on a different drive or filing system from the databse) can be referenced in a database field so a click on the field retrieves the file.
- JPEG, Sprite and Draw files can be scaled to fit within a defined rectangle in the record window. This affects only the display, it does not alter the original file.
