1.More accurately represents shape of features 2.Many users can edit geophic data 3.Modern orgs prefer a database approach to working with map layers 4.Provides a uniform and IT compliantrepository for geophic data 5.Geodatabase is ESRI preferred format | Geodatabases Advantages |
1.Putting two tables together to makeone table 2.Join two tables one-to-one by row 3.Join on primary key attributes 4.Primary key attributes do not need to have the same names 5.Must have the same values and datatypes | data table joins |

1.ESRIs highly compressed format2.directly readable by ArcGIS software3.many ESRI data and map datasets are natively in SDC format | Smart Data Compression SDC |
TIFF (Tagged Image File Formats), GIF (Graphic Interchange Format), JPG (Joint Photographic Experts Group) | digital File formats |
high quality images, commonly used in publishing, sizes are large because uncompressed | TIFF |
ideal for schematic drawing that have relatively large areas with solid color fill and few color variations, small file sizes | GIF |
most widely-used format for photographs and other images that have a lot of color variations, uses file compression at the expense of picture detail | JPG |
