I Provide High quality work at a low price. You may find other documents on the Internet or this website however they don't always cover all the BTEC Criteria. This is why my work has the best standards and COVERS ALL THE CRITERIA, i go into a lot of detail from pass to distinction tasks, so you can use it as a guide/ template. Each piece of works takes around 3-4 hours and I only ask for a small contribution of your money.

M3- Export data to an external source
M3 requires learners to export the results of either a query or report to another application. To evidence this, learners could provide a screen print of a directory containing the exported data in a suitable file format or a print of the data in its new format. Alternatively, for M2 and M3, an appropriately documented demonstration of learners exporting and importing data would be appropriate. The tutor could ask for a particular set of data to be exported to a particular application.

P1- Explain the features of a relational database
For P1, they must explain the features of a relational database. Evidence for this could be, for example, a written report, a presentation or a written discussion. Note that the features include benefits and learners need to be able to quote aspects that relate to the efficiency of storage of information with a minimum of data redundancy and also the ease by which information can be extracted from the database as required.

M1- Explain referential integrity and the purpose of primary keys in building the relationships between tables
For M1, learners should show evidence that they understand the concept of referential integrity and the mechanisms that exist to support the enforcement of referential integrity within a database package. They should also be able to explain the purpose of primary keys and how they are used to build the relationships between tables. Reference should also be made to foreign keys.

P4- Create features in data entry forms to ensure validity and integrity of data
For P3, learners will have implemented their design and populated the tables. Relationships should have been established and referential integrity enforced, this will allow cascaded updating and deletion of linked records. Evidence will come from annotated screen prints.

D1- Design a control system that uses different types of sensors
For D1, learners need to design a control system that uses different types of sensors. ‘Different’ in this case should be taken to mean the most diverse set possible, less is definitely not more in this case. Evidence could include plans, designs, sketches, presentations, user feedback and written reports.
