Common ArcEngine topology Interfaces

Topology is a set of topological relationships between Feature classes under the same Feature set (FeatureDataset. Therefore, to participate in all the element classes of a topology, the topology check must be accurate within the same element set (that is, with the same spatial reference. One element set can have multiple topologies, but each element class can on

A dvb-based Data Broadcast System developed by the Blue topology company for cable TV networks

[Abstract]: This paper introduces the DVB-based Data Broadcast System (IP over DVB) developed by the Blue topology company for cable TV networks, which focuses on the system structure, the front-end system structure and implementation, and the design and implementation of the backend data receiving card. Key parts of the system: Front-End Server software, multi-protocol wrappers, and data receiving cards are independently developed by Alibaba Cloud an

Topology usage in arcengine (ZZ)

The spatial topology describes the spatial location relationships of geographical objects in nature-adjacent, overlapped, and connected. It is part of the spatial attributes of geographical objects. currently, in the data storage mode provided by ESRI, Coverage and GeoDatabase can establish a topology, while data in the Shape format cannot create a topology. 1.

Understanding the concurrency mechanism of storm topology

composition of runtime topology: Worker processes, executors (performer thread), and Tasks Storm distinguishes between the following three main entities and is used to run a topology on the storm cluster: 1.Worker processes 2.Executors (thread) 3.Tasks Here is a simple example of these 3 relationships: A worker process is responsible for performing partial subsets of t

Topology design for deployment of front-end servers

Topology Builder is an installation component of Microsoft Lync Server 2010. Use Topology Builder to display and adjust the topology that you plan. It also validates the topology and, when you are ready to start deployment, can be used to write topologies for your Lync Server 2010 department. When Lync Server 2010 is i

Topology (ZZ) in ArcGIS)

1. first look at the implementation of the topology in ArcInfo:Geodatabase became a new spatial data model after ArcGIS 8. It uses an open structure to store spatial data (including vector, raster, image, and three-dimensional terrain) and its related attribute data in the DBMS of the industrial standard database management system. A Feature Class, such as a river, a border, a parcel, or a pole, corresponds to a table in the DBMS, and a specific Featu

Replication topology for Active Directory-eight of the Active Directory family

In the previous blog we deployed additional domain controllers in the domain, and we already know that each domain controller has an Active Directory database with the same content, and today we are going to discuss the replication topology used by the additional domain controller for Active Directory replication. In the NT4 era, domain controllers are divided into two categories, the PDC and the BDC. The PDC is the abbreviation for the primary domai

Twitter Storm: Run topology configuration on a production cluster

Running topology on a production cluster is similar to local mode. Here are the steps: 1) Define topology (if Java is the case, use Topologybuilder) 2) Use Stormsubmitter to submit the topology to the cluster. Stormsubmitter parameters are: Topology's name, topology's configuration object, and topology itself. Like wha
