ADD XY DATA TOOL Takes a table containing XY data & Creates a layer from it. The table must alreadty contain two separate fields containing X & Y ( these X & Y fields must be Numeric data type ) coordinate data. The new layer will contain one point for each record in the table.
Exercise : - Provided RO details along with the Coordinates. Plot these RO locations
Go to Tools & click Add XY data tool.
Add XY window appears

TOPOLOGY Topologies maintain high-quality spatial data by ensuring that your features conform to simple rules. When you set up a geodatabase with a topology, you specify which feature classes participate in the topology and define rules that control when and how features can share geometry. For example, in a geodatabase of states and coastlines, you might have a rule stating that polygons cannot overlap each other and another rule that the coastline must coincide with the boundaries of the states. These rules would help you ensure, when updating the state boundaries to match the coastline, that you don't inadvertently create places where the states overlap or where a state's coastal edge doesn't match the shape of the coastline.
For Using this option all the layers must be in Featureclasses & should be inside a dataset.
This option is not available in ARCVIEW license.
Right click on the dataset having the layers for which the topology is to be checked.
Go to New topology option.
TOPOLOGY – DEFINE RULES ENTER TOPOLOGY NAME & DEFINE THE TOLERENCE ( GENERALLY KEEP THE TOLERENCE AS THE DEFAULT VALUE ) SELECT THE LAYERS FOR WHICH THE TOPOLOGY IS TO BE CHECKED ASSIGN RANKS TO THE LAYERS ( FOR OUR PURPOSE DON’T CHANGE THE RANK, KEEP THE DEFAULT VALUES ) CLICK ON THE ADD RULE BUTTON TO ADD THE TOPOLOGICAL RULES ONCE THE ADD RULE BUTTON IS CLICKED THE WINDOW SHOWN ABOVE APPEARS & THE USER CAN DEFINE THEIR RULES ON THE LAYERS. ONCE RULES ARE DEFINED CLICK NEXT & FINISH BUTTON. THE USER WILL RECEIVE A MESSAGE AS SHOWN ABOVE. CLICK ON YES BUTTON
TOPOLOGY – VIEWING THE TOPOLOGICAL ERRORS ONCE THE PROCESS IS COMPLETE, A TOPOLOGY LAYER IS CREATED INSIDE THE DATASET. ADD THIS TOPOLOGY LAYER IN ARCMAP & THE TOPOLOGICAL ERRORS WILL BE DISPLAYED

GEOMETRIC NETWORK A geometric network is a connectivity relationship between a collection of feature classes in a feature dataset. Each feature has a role in the geometric network of either an edge or a junction. Multiple feature classes may have the same role in a single geometric network.
