{{importantNote| Be aware of the following when running IMSMA in a client/server installation:
* The server and client(s) must be running the exact same version of IMSMA.
* The gisServer.properties file on the server must be configured.
* The client(s) must be configured to connect to the server.
* Maps only need to be installed on the server.
* Data entered into the server or clients will be automatically rendered to all clients (as well as the server). However, GIS geospatial information (points, polygons) will NOT be immediately rendered to all clients. To either post your GIS-related geospatial updates to the server (thus making them available to other clients) or to receive updates from the server, you must log out of IMSMA and then log back in.
* Fonts will need to be installed on both the server and client(s)

===Server===__NOEDITSECTION__
The IMSMA<sup>NG</sup> server stores data and manages much of the data processing. The server has two main parts, the datastore and the business layer. The datastore is where data is stored for retrieval by the IMSMA<sup>NG</sup> client. IMSMA<sup>NG</sup> uses a PostGreSQL PostgreSQL relational database to store data on the server. Additionally, IMSMA<sup>NG</sup> stores other data including attachments and some configuration files on the server in file format. The PostGreSQL PostgreSQL database is accessible via a variety of database access tools designed for browsing relational databases.
{{warning|While the database contains many relational database constraints designed to preserve data integrity, all updates of data should be handled through the business layer rather than with direct SQL updates in order to maintain integrity. Failure to do so will likely cause data corruption or loss}}
===Client===__NOEDITSECTION__
The IMSMA<sup>NG</sup> client is the interface through which users can connect to the server and browse the system, enter data and generate outputs. The client includes an integrated GIS component and reporting tools. Based on ESRI’s ArcGIS Engine, the GIS component performs all geospatial calculations including distance/bearing calculation, coordinate conversion and reprojection. The GIS component also allows each client to load and manage its own maps and geographic data which the client receives from the IMSMA<sup>NG</sup> server. As a result, each client receives and locally stores a complete copy of geographic data from the IMSMA<sup>NG</sup> server when it is connected to the server. This synchronized data is stored in a client ―sandbox‖ separate from the server and can always be updated by connecting to the server.
JasperSoft’s iReport tool is built into each IMSMA<sup>NG</sup> client and allows users to access data from the database via the business layer. With iReport, users can generate reports containing tabular data, subreports and cross tabs as well as various types of charts and graphs. These reports can easily be localized into any language that IMSMA<sup>NG</sup> supports. Additional reporting options include direct connections to the IMSMA<sup>NG</sup> database via ODBC. This functionality supports tools such as Crystal Reports, Microsoft® Access®, Microsoft Excel® and various open-source reporting tools.
* Since IMSMA NG is a 32-bit application there is no effect by reserving more than total 4 GB.
* On the physical server in a client/server configuration there is need to start the client, take backup and restore so do not set the client process memory to less than 512. }}
