What is difference between fixed length record and variable length record?
A file where all the records are of the same length is said to have fixed length records.Advantage : Access is fast because the computer knows where each record starts.Eg If each record is 120 bytes long thenthe 1st record starts at [Start of File] + 0 bytesthe 2nd record starts at [Start of File] + 120 bytesthe 3rd record starts at [Start of File] + 240 bytes etc.....Disadvantage : Using Fixed length records, the records are usually larger and therefore need more storage space and are slower to transfer (load or save).One or more of the fields can be of differing lengths in each record, called variable length recordsAdvantages:the records will be smaller and will need less storage spacethe records will load fasterDisadvantages:The computer will be unable to determine where each record starts so processing the records will be slower.
What is the difference between char and varchar data types?
The CHAR datatype uses a fixed length, where as the VARCHAR datatype can be variable in length up to the maximum value specified for the length. If you insert "Hello" into a CHAR(10) field, the column would actually contain "Hello " with 5 trailing spaces. The same value inserted in a VARCHAR(10) field would contain "Hello". char datatype is fixed length data type and it store maximum 255 characters while varchardatatype store up to 4000 character of variable length datatype
How much is 10 months in days?

What is difference between fixed overhead and variable overhead?
The difference between fixed overhead and variable overhead is that fixed overheads are the ones that do not change regardless and variable overheads are the ones that vary depending on the number of units that it produces. An example of fixed overhead is a managers salary.

What is fixed length?
A fixed length record is a data structure that contains a standard amount fields, within the actual record.
What are the advantage of using fixed length fields instead of variable length fields in a database?
A fixed length field is one which contains a set number of characters.With fixed length fields, the fields may need to be padded out to the right length, eg with characters.eg If a Surname field is set at 10 characters then the name SIMPSON would need 3 s added on to the end of it.Advantage - Every record is the same size, so it is possible for the computer to calculate exactly where each record starts in the file and therefore it is quicker for the computer to find a particular record.
What is Relative file names?
An organization in which all records are a fixed logical record length and records are extracted through the specification of their relative record number.

What is a record-based data model?
-> A record based data model is used to specify the overall logical structure of the database.-> In this model the database consists of a no. of fixed formats of different types.-> Each record type defines a fixed no. of fields having a fixed length.-> There are 3 principle types of record based data model. They are :1. Hierarchical data model.2. Network data model.3. Relational data model.
Are all fixed length files are of the same length?

What is a fixed jurisdictional area?
A fixed area of a rectangle is an area that doesn't change. An area is a quantity that measures the space of a shape.Consider this example:A = length x width, which is the formula of a rectangleIf A is fixed, then it depends on what values length and width are. Then, length is indirectly proportional to width in order for A to remain fixed.
