What is a Database Sample?
It’s a taste of the real thing. These are fully contained, downloadable database functionality samples of our Raima Database Manager (RDM) , and each download highlights a certain feature within RDM. Click on the Database Samples links to view the complete series for each API. Duration = 5 minutes or less.
Note: Windows samples require Visual Studio 2008 or 2010 and Linux samples require a standard Linux development environment.
- Download the sample.
- Build it – it’s all set up.
- Run it in your debugger & watch.
- “Oh, That’s easy!”

|Windows||Linux 32-bit||Linux 64-bit||Description|
|Hello World||Hello World||Hello World||Hello World. Pre-initialized database. Create one record, read all records & print string.|
|OBJ02||OBJ02||OBJ02||Hello World. If database doesn’t exist (first time), it will be created and initialized. If it does exist, new records will be added. Same create/read algorithm as in HelloWorld.|
|OBJ03||OBJ03||OBJ03||Set instance. Create/initialize a new database containing two record types and a set between them. Create one owner, several members, then scan owner(s) obtaining record scan cursors from the Db class and the Cursor class navigation methods.|
|OBJ04||OBJ04||OBJ04||Hierarchy. Create/initialize database if it doesn’t exist. Build on previous sample but make it two levels with three record types.|
|OBJ05||OBJ05||OBJ05||Indexing. Create/initialize database if it doesn’t exist. Create 10 records with random index. Scan through index & print records in order using the Cursor class key scan cursors.|
|OBJ06||OBJ06||OBJ06||Mixed model. Rather than the Cursor classes Table scan methods like the two previous samples, use the Cursor classes Keyscan methods to scan through top of hierarchy, then scan members as sample 4 does.|
|OBJ07||OBJ07||OBJ07||Many-to-many. Three record types, two sets constructing a many-to-many relationship. Populate with a few records. Using the Cursor classes Set Member navigation methods scan from one side, then scan from the other side.|
|OBJ08||OBJ08||OBJ08||Multiple databases. Create/initialize two databases. Populate them. Incrementally open them in the same task. Use dbn to demonstrate usage of both databases from same task.|
|OBJ09||OBJ09||OBJ09||Multiple databases opened in a union. Demonstrate key scan through the union.|
|OBJ10||OBJ10||OBJ10||Currency. Using hierarchical database, find a leaf record through an index, make it the current member of its set, navigate up. Show other members of owner records.|
|OBJ11||OBJ11||OBJ11||Transaction. Create records in a transaction. Commit. Navigate through created records.|
|OBJ12||OBJ12||OBJ12||Transaction abort. Commit ont transaction, then begin another transaction and abort it. Navigate through created records to see only committed records.|
|OBJ13||OBJ13||OBJ13||Shared mode. All previous databases were using ‘x’ mode. This one creates two tasks. In the first one, a database is created and populated. In the second one, the database is opened and read is attempted but times out.|
|OBJ14||OBJ14||OBJ14||Multi-user. Begin multiple writer threads that will use transactions. Begin multiple reader threads that will use read locks.|
|OBJ15||OBJ15||OBJ15||TFServer. Spawn tfserver. Begin multiple writer and reader threads that use tfserver.|
|OBJ16||OBJ16||OBJ16||Multi-process. Spawn tfserver. Begin multiple writer and reader processes that use tfserver in client/server mode.|
|OBJ17||OBJ17||OBJ17||Read-Only-Transactions. Spawn tfserver. Begin multiple writer and reader processes, but readers use MVCC read-only-transactions.|
