Database design and optimization

SQL, which stands for Structured Query Language, is a programming language that is used to communicate with and manipulate databases. In order to get the most of the mounds of data they collect, many businesses must become versed in SQL. The SQL programming language was first developed in the 1970s by IBM researchers Raymond Boyce and Donald Chamberlin. The programming language, known then as SEQUEL, was created following the publishing of Edgar Frank Todd`s paper, “A Relational Model of Data for Large Shared Data Banks,” in 1970. In his paper, Todd proposed that all data in a database be represented in the form of relations. It was based on this theory that Boyce and Chamberlin came up with the SQL.

PESTLE tool can be used to analyse various external factors, which impact schools.

SWOT (Appendix 3) Increase parent engagement by holding quarterly workshops: analysis clearly indicates the benefits of this objective and it will add much value to the school. It has highlighted the budget strain for additional workshops but the opportunity highlighted a possible solution parent’s contribution, another weakness could be lack of staff, however PTA involvement can tackle this.
