Resident Database Manager

The Resident Database Manager (RDM) is a software tool set for applications that access and update information residing in main-memory. Traditionally, the code responsible for handling main-memory data is handwritten. RDM allows developers to declaratively specify objects and operations on them using a SQL-like language to generate an embedded main-memory database in C. The workflow is as follows.

1. The LDM compiler compiles the logical data model into a physical plan.
2. The PDM compiler translates the physical data model into the database in C.
3. The CDB compiler takes the application written in an extended C language called C/DB and compiles it to C.
4. A C compiler is invoked to compile and link the application and the database.

Installation

This version of the RDM tool requires the following to be installed.

• sbcl
• bison
• flex
• a C compiler
• indent (C code beautifier)

To compile, run make from the src/ directory.

Usage

Included in the samples folder are examples of how RDM could be used. The frv example is used.

1. Run ./lpdmc frv.ldm to get frv.c and frv.h.
2. Run ./cdbc -f frv.pdm frvMain.cdb to get frvMain.c.
3. Run gcc -o frv frvMain.c frv.c.

The application is then compiled and ready to run: ./frv.
