To provide query access to feature data in a map format, publish an ArcGIS Server map service.

The two main types of spatial data you share in this way are feature and imagery data. In most cases, you publish web services to allow people to visualize and query your spatial data in a map format. Functionality, web services, and data resources You need to grant ArcGIS Server permissions to the data in these locations and register these data sources with the ArcGIS Server site before you publish. For example, maps and geoprocessing models reference various feature classes stored in a database, geodatabase, or shapefiles in a folder. Some resources references additional data. The ArcGIS Server site must have access to the location of the resource to copy it. Similarly, maps you publish are copied to the ArcGIS Server machine. For example, if you publish a locator as a geocode service, a copy of the locator is placed on the ArcGIS Server machine to ensure that ArcGIS Server has sufficient permissions to access it. When you publish a resource such as a map, tool, or locator as a web service, that resource is placed on the ArcGIS Server machine. Web services access the data from directories, databases, and geodatabases you make accessible to the ArcGIS Server site. How ArcGIS Server stores and accesses data The type of data you want to make available to others and what you want people to do with that data determine the type of web service you publish. If the data is relatively static, you can cache the data in a location separate from your data source to improve drawing performance. In the case of feature and imagery data, you can publish web services that access the data without duplicating it. They access the data in your storage locations, allowing you to share that data without giving people direct access to the storage locations. Web services, essentially, are your data.
