single page of the database file. + Usually 1024. + +Number of pages in the whole file + + The number of 32768-byte pages that go into forming the complete + database + +Pages that store data + + The number of pages that store data, either as primary B*Tree pages or + as overflow pages. The number at the right is the data pages divided by + the total number of pages in the file. + +Pages on the freelist + + The number of pages that are not currently in use but are reserved for + future use. The percentage at the right is the number of freelist pages + divided by the total number of pages in the file. + +Pages of auto-vacuum overhead + + The number of pages that store data used by the database to facilitate + auto-vacuum. This is zero for databases that do not support auto-vacuum. + +Number of tables in the database + + The number of tables in the database, including the SQLITE_SCHEMA table + used to store schema information. + +Number of indices + + The total number of indices in the database. + +Number of defined indices + + The number of indices created using an explicit CREATE INDEX statement. + +Number of implied indices + + The number of indices used to implement PRIMARY KEY or UNIQUE constraints + on tables. + +Size of the file in bytes + + The total amount of disk space used by the entire database files. + +Bytes of user payload stored + + The total number of bytes of user payload stored in the database. The + schema information in the SQLITE_SCHEMA table is not counted when + computing this number. The percentage at the right shows the payload + divided by the total file size. + +Percentage of total database + + The amount of the complete database file that is devoted to storing + information described by this category. + +Number of entries + + The total number of B-Tree key/value pairs stored under this category. + +Bytes of storage consumed + + The total amount of disk space required to store all B-Tree entries + under this category. The is the total number of pages used times + the pages size. + +Bytes of payload + + The amount of payload stored under this category. Payload is the data + part of table entries and the key part of index entries. The percentage + at the right is the bytes of payload divided by the bytes of storage + consumed. + +Average payload per entry + + The average amount of payload on each entry. This is just the bytes of + payload divided by the number of entries. + +Average unused bytes per entry + + The average amount of free space remaining on all pages under this + category on a per-entry basis. This is the number of unused bytes on + all pages divided by the number of entries. + +Non-sequential pages + + The number of pages in the table or index that are out of sequence. + Many filesystems are optimized for sequential file access so a small + number of non-sequential pages might result in faster queries, + especially for larger database files that do not fit in the disk cache. + Note that after running VACUUM, the root page of each table or index is + at the beginning of the database file and all other pages are in a + separate part of the database file, resulting in a single non- + sequential page. + +Maximum payload per entry + + The largest payload size of any entry. + +Entries that use overflow + + The number of entries that user one or more overflow pages. + +Total pages used + + This is the number of pages used to hold all information in the current + category. This is the sum of index, primary, and overflow pages. + +Index pages used + + This is the number of pages in a table B-tree that hold only key (rowid) + information and no data. + +Primary pages used + + This is the number of B-tree pages that hold both key and data. + +Overflow pages used + + The total number of overflow pages used for this category. + +Unused bytes on index pages + + The total number of bytes of unused space on all index pages. The + percentage at the right is the number of unused bytes divided by the + total number of bytes on index pages. + +Unused bytes on primary pages + + The total number of bytes of unused space on all primary pages. The + percentage at the right is the number of unused bytes divided by the + total number of bytes on primary pages. + +Unused bytes on overflow pages + + The total number of bytes of unused space on all overflow pages. The + percentage at the right is the number of unused bytes divided by the + total number of bytes on overflow pages. + +Unused bytes on all pages + + The total number of bytes of unused space on all primary and overflow + pages. The percentage at the right is the number of unused bytes + divided by the total number of bytes. + +<a name="sqlx"></a>******************************************************************************* +The entire text of this report can be sourced into any SQL database +engine for further analysis.
