Anyone know about Pick D3 database? (Tigerlogic)

Hi, can anyone able to help me?

Anyone know about this Pick D3 database? (company now known as TigerLogic/RainingData)
http://www.rainingdata.com/products/dbms/d3/index.html

http://www.rainingdata.com/products/dbms/d3/d3.pdf

This database called itself as multidimensional database system, and it accept MultiValue and dynamic data type.

QUOTE

Limitless:
Files may consist of an unlimited number of records. Records may have up to two billion fields. Fields may be up to 2GB (numeric or string). A process may open up to 32,000 files.

Dynamic:
Fields can change dynamically, thus having no length or data type restrictions. Adding fields to a file does not require reformatting or restructuring.

Multlti-value:
Transcending the limitations of the two-dimensional relational model, TigerLogic’s multi-value model adds additional dimensions to reflect true business data modeling. These multi-values along with their possible sub-values and associated sub-multi-values permit the stacking of data and/or keys within a field or fields. This eliminates the need for dependent tables and joins.

Secondary Indexing:
Cross-indexing is supported for fast access to records via secondary keys. Balanced-tree index maintenance and synchronization is performed automatically by the system during all updates.

Is this database obselete? how reliable is it if the database need to be implement on say 20 branches and 50 concurrent users, storing 1000 records per day.

Also, how does it compared to opensource database likes MySQL, PostgreSQL, Firebird?

Thanks.

My NDSL Bottom Screen seems cannot touch anymore?

1st please pardon my poor english. Hope u can understand what i am trying say.

Yesterday, I try to replace my DS Lite screen protector. After replacing, I use a bit of water to clean up the bottom screen. However it leave a very small watermark on the upper left of the screen.

1st, I thought the water got inside the screen protector. So I try to use the a card to press it out. But the watermarks seems spread and become bigger. So I decide to re-apply the screen protector.

So I take out the screen protector again. Oh Shit!! the the watermark is under the LCD, not screen protector. I wonder whether how the water get into the screen.

Below is the photos I took for my NDSL Bottom LCD. Can u judge whether water get inside the LCD or the Liquid inside LCD leak out (maybe I wipe too hard when cleaning with water)?

The bubble is belong to the screen protector, while the watermark are darker color.

The watermark a little bit visible when gameplay.

Now the screen cannot calibrate and touch, however it seems to have "invisible pen" touching continuously varies point of the screen. So now I can only play the game which dont need to touch. So can anyone tell me whether what actually happened? Anything spoilt?

Also anyone know where can I buy Tri-wing Screwdriver so I can take out the screw of NDSL. It look like this (right):-

Also anyone know where can I buy spare parts of the Nintendo DS Lite Touch Screen and Bottom LCD in case they spoilt?
