It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using ‘Content here, content here’, making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for ‘lorem ipsum’ will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

Unmatched Cloud Database Management

Raima delivers unmatched data management on the backend with a direct dialect offered to connect directly to the SymmetricDS replication solution. Developers can both embed Raima’s linkable library database solution directly into their application, to manage data nearly maintenance-free, and use the published APIs for extension, embedding into applications and remote management.

				
					create database students;
create table class (
    class_id char(5) primary key,
    class_name char(29)
);
create table student (
    name char(35) primary key
);
create table intersect (
    begin_date integer,
    end_date integer,
    status char(9),
    current_grade integer,
    my_students char(5) references class,
    my_classes char(35) references student
);

Multiple Indexing Methods

RDM supports the use of B-tree, Hash, R-tree and AVL-tree indexes. B-tree, AVL -tree and Hash indexes are optimal for various types of numerical and character data, while R-Tree indexes are perfect for geospatial data. Raima supports whichever index type is most optimal for the mobile database developer.

Multiple Indexing Methods

Multi-Computer (Client/Server)

Multi-Thread Single Computer

Single-Thread (exclusive access)

Single-Thread In-Memory

Multi-Computer (Client/Server)

Multi-Computer Configuration - Amazingly Fast

When multiple computers are involved, they communicate through TCP/IP. If client and server are instead on the same computer, shared memory is used to speed it up.

Multi-Thread Single Computer

Multi-Thread Single Computer Configuration - Even Faster

But when the runtime and TFS are in the same process, the inter-process communication is avoided, resulting in even more speed.

Multi-threaded applications are great for handling multiple windows on a screen, each with independent contents.

Single-Thread (exclusive access)

Single-Thread (exclusive access) - Faster than that!

Simpler, single-user applications have an advantage because there is no concurrent access to the database, hence no locking or waiting.

Single-Thread In-Memory

Single-Thread, In-Memory Database - The Absolute Fastest

Now, load the database from disk into memory and you have database management with all the stops pulled.

The RDM in-memory database option allows for volatile (it goes away when the application stops) and persistent (loaded from disk and saved to disk) databases.

It’s faster because there is no disk latency for reading and no waiting for disk writes during a transaction commit.

These are vulnerable to data loss if the application terminates without saving the data. Sometimes it’s a risk worth taking!
