If you've got a Palm then you'll know how convenient it is as an information manager and for storing important stuff. If you work with databases on a regular basis, you can use your device to transport and view records wherever you go.

Palm Zlib is a piece of software designed to let you view CSV (comma-separated values) databases from your handheld. Though fairly basic in its interface design, the app allows you to quickly access any supported databases from both your internal memory or from any expansion cards it detects.

You can conduct searches for information within a database, and specify values or characters to look for. Searching is slow, but exhaustive. Databases are displayed clearly and can be easily scrolled through using the slider at the right of the interface.

I would emphasise that this is a basic viewer - there are no tools for editing data whatsoever, and you can't even beam data from your device.

Nevertheless, as a way of viewing data on the fly, Palm Zlib enables you to do so with minimal hassle.

Palm ZLib DB Viewer (pzdbView) is a PalmOS application for PalmOS 3.5 or higher. It can be used to view (and search in) CSV-like databases which are stored in compressed form on your Palm Storage Memory.

The whole application requires a bit less than 12K of storage memory, excluding databases, of course. On most Palm devices you will as well need SysZLib (which will need about 30K extra space). Most users will already have it (for ebook readers, for example); if not, 42K of storage are still far less than any other database viewer I know needs.

Since all data are decompressed on the fly (and the decompressed form is not stored anywhere), searching is quite slow (because it has to transparently decompress the whole database every time). A full text search on a database of Germany's calling codes takes about 8 seconds on a Palm Vx. On the other hand, if you have larger databases you rarely need (but sometimes you need them), trading storage RAM (pzdb databases need about 20% of the space an equivalent Pilot-DB database needs) for search time is an acceptable compromise.
