Therefore Personal Geodatabases can be opened directly in Microsoft Access, but the entire geodatabase can only have 2 GB of storage. On the other hand, Personal Geodatabases were originally designed to be used in conjunction with Microsoft Access and the Geodatabase is stored as an Access file (.mdb).

When a shapefile is opened in Windows Explorer it will look different than when opened in ArcCatalog. dbf – this file stores the attribute information for the featureĪll files for the shapefile must be stored in the same location with the same name or else the shapefile will not load. shx – this file stores the index of the geometry shp – this file stores the geometry of the feature One shapefile must have at least 3 files but most shapefiles have around 6 files. Users are allowed to create points, lines, and polygons with a shapefile.

Do not store NULL values in a field when a value is NULL, a shapefile will use 0 instead.Cannot store date and time in the same field.Do not support names in fields longer than 10 characters.Takes up more storage space on your computer than a geodatabase.Therefore, shapefiles have many limitations such as: Shapefiles are simple storage formats that have been used in ArcMap since the 1990s when Esri created ArcView (the early version of ArcMap 10.3). Ever wonder what the difference between a shapefile and a geodatabase is in GIS and why each storage format is used for different purposes? It is important to decide which format to use before beginning your project so you do not have to convert many files midway through your project.
