What is the difference between a File Geodatabase and a Personal Geodatabase in an ArcGIS software environment???

When talking about geographical databases specifically within the ArcGIS software environment, we are talking about the place where all types of data are stored, stored and analyzed, whether with regard to aerial photographs, satellite visuals, map images (Raster) and data digitization, which is represented through The drawing and adding data (Attribute Table) comes in the form of a polygon, a line and a point (Vector) in addition to the metadata represented by tables not linked to a geographical location (Table).

• Geographical database, which preserves and stores geographical data that are somewhat similar in one database, for example, a geographical database for a city that contains data on water and sewage lines, land boundaries and geographical areas, and maps on analysis and management of firefighting and places affected by floods.
• When opening any project within the ArcMap program, and to ensure the preservation, storage and analysis of data, we create a geodatabase or transfer files outside ArcGIS to the geodatabase. From here, the types of geodatabases are identified:

1. Geodatabase File: It has a .gdb format and has a storage capacity to save data of unlimited size. This type of geodatabase allows to compress all the saved geographical data and create spatial indexes to quickly identify features, as well as modify the data more efficiently.
2.  Personal Geodatabase: .mdb format The storage capacity to save the data does not exceed 2 GB, it has many restrictions in managing, saving, storing and analyzing the data when compared with the geographical database file.

• It is recommended that you use the geodatabase file in any project within your ArcGIS software.

Data that geodatabases store within an ArcGIS environment:

1. Feature Dataset
2. Attribute Table
3. Vector classes named Feature Class
4. Cartographic Representation
5. Annotation texts
6. Dimensions
7. Define relationships between data Relationship Class
8. Raster Dataset . Raster Dataset
9. Raster Catalog
10. Engineering Correction Topology
11. Geometric Network Analysis
12. Network Dataset
13. Terrain
14. Locating Locator
15. Survey Dataset
16. Toolbox
