Object Oriented API for C++ Database Samples

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 2013 or later and Linux samples require a standard Linux development environment.

Downloadable Database Samples

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.
