Writing a database. The strucure of storage format

I'm writing a database and i need help with the file strucure of the database.
Can anyone analyse my file structure ??? Any ideas, suggestions etc. ?

I'm thinking in this format:

[Header]

 Tables - Offset to tables description
 FreeSpaces - Offset to free spaces description

[FreeSpaces]

 Start - The offset to start of the free space  Length - The length of the free space
 NextFreeSpace - Offset to next FreeSpace description

[Tables]

 Table Data - The name of table etc.
 Fields - Offset to fields description
 Data - Offset to data description
 NextTable - Offset to next Table description

[Fields]

 FieldData - The name, type etc.
 NextField - Offset to next field description

[DataDescription]

 Data - Offset to the data of table
 NextData - Offset to next Data Description

[Data]

• for each field DataLength - The length of the data Data - The data
