Main objects Tables – Data collection objects Queries – Questions of your data Forms – Predefined format to display or enter data Reports – Printable version of database information Field (Column): a single piece of information. Could be a name, or a number. Record (Row): a collection of related fields. A number of pieces of information that relate to the same object. Records on an employee, their name, address, social security number, phone number, etc. This would be the employee’s record. Table (File): a collection of related records. If you put all the employee records together, you have a table of employees.

MySQL - Data Types MySQL uses many different data types broken into three categories − Numeric Date and Time String Types.

Numeric Data Types MySQL uses all the standard ANSI SQL numeric data types, so if you're coming to MySQL from a different database system, these definitions will look familiar to you. The following list shows the common numeric data types and their descriptions: INT  TINYINT  SMALLINT  MEDIUMINT  BIGINT  FLOAT(M,D)  DOUBLE(M,D)  DECIMAL(M,D)

Date and Time Types The MySQL date and time datatypes are as follows − DATE − A date in YYYY-MM-DD format DATETIME − A date and time combination in YYYY-MM-DD HH:MM:SS format TIMESTAMP - A timestamp between midnight, January 1st, 1970 and sometime in 2037. This looks like the previous DATETIME format, only without the hyphens between numbers; 3:30 in the afternoon on December 30th, 1973 would be stored as 19731230153000 (YYYYMMDDHHMMSS ). TIME − Stores the time in a HH:MM:SS format. YEAR(M) − Stores a year in a 2-digit or a 4-digit format

String Types Although the numeric and date types are fun, most data you'll store will be in a string format. This list describes the common string datatypes in MySQL. CHAR(M) − A fixed-length string between 1 and 255 characters VARCHAR(M) − A variable-length string between 1 and 255 characters in length. BLOB or TEXT − A field with a maximum length of 65535 characters. TINYBLOB or TINYTEXT − A BLOB or TEXT column with a maximum length of 255 characters MEDIUMBLOB or MEDIUMTEXT − A BLOB or TEXT column with a maximum length of 16777215 characters. LONGBLOB or LONGTEXT − A BLOB or TEXT column with a maximum length of 4294967295 characters.
