What is a DBMS?

“A Data Base Management System (DBMS) is a computer program (or more typically, a suite of them) designed to manage a database, a large set of structured data, and run operations on the data requested by numerous users.”

(source :From Wikipedia, the free encyclopedia)

For Whom

• Small centre that don’t have any DBMS or outdated solutions to digitize, store and process large amount of data.

• Small centre looking for a simple, customizable and license free solution to store, analyse and generate reports and maps on large amount of data.

System Requirement for MCH:

Work station (stand-alone) Stand-alone configuration (typically for small centre ):

• Processor speed of 1.5 GHz or faster

• A video resolution of at least 1024 x 768

• 1 GB of RAM (minimum 500 MB)

• Operating system, Windows XP or later

• Disk space 5 GB

System Requirement for MCH:

Network configuration (client-server):

Network configuration, typical configuration for NMHSs with regional offices:

• Two servers are recommended, 1 operational and 1 mirror.

• Processor speed of 2 GHz or faster,

• A video resolution of at least 1024 x 768, 2 GB of RAM

• A 250 GB hard disk

• 100 GB of free space for the database

• Operating system Windows 2000 professional, Windows XP, Windows 2000 server or Windows 2003 server or later.

Advantages

• OPEN SOURCE based

• No fees for the licenses.

• Full access to the source code.

• A configurable system (you define your variables

and stations etc.), and allows you to connect external modules.

• Manages Hydrological, Climatological and

Meteorological data under a unique platform.

• Multilingual, using an external text file, currently

available in Spanish, French and English.

Disadvantages

• Configurable System

• Few developers

How and where can you get MCH?

• An official request signed by the

Permanent Representative of your

country with WMO.
