Study Notes
Programming Languages
- In modern software solution stacks such as LAMP, LAPP, and WAMP, the "P" does not stand for Python, Perl, or Pascal, but rather for PHP.
Database Catalog Metadata
- Metadata found in a database catalog includes table and view names, relationship descriptions, and index definitions, but excludes values in a primary key field.
Data Consistency
- Data consistency means giving each user a consistent view of the data, including changes, and can be achieved by using properties such as the Validation Rule property to improve data entry accuracy.
Access Database Recovery
- The compact and repair feature potentially helps recover data in an Access database.
SQL Statement Permissions
- The GRANT ALL on STUDENTS to cyclone1 SQL statement gives user cyclone1 the ability to select, insert, update, or delete records from the Students table.
Primary Key Field Constraints
- The primary key field constraints include no null values, unique values, but do not include a requirement for all values to have a matching value in the foreign key field of the table in which it has a one-to-many relationship, or to contain data within the data type assigned to that field.
Database Changes
- Changing relationships between tables would most likely require the most rework to existing programs and queries.
Version Control
- GitHub and BitBucket are popular websites for hosting projects that use the Git language for version control.
