Relational Database Design 1 10 Relational Database Design Anomalies can be removed from relation designs by decomposing them until they are in a normal form. Several problems should be investigated regarding a decomposition. A decomposition of a relation scheme, R, is a set of relation schemes {R1, . . . ,Rn} such that Ri⊆R for […]

Normal Forms Normal Forms for Relational Databases 1 Normal Forms for Relational Databases • criteria for a good database design (i.e., to resolve update anomalies) • formalized by functional (or other) dependencies 2 Normal Forms: • 1NF, 2NF, 3NF (Codd 1972) • Boyce-Codd NF (1974) • Multivalued dependencies and 4NF (Zaniolo 1976 and Fagin 1977)

Hash-Based Indexes 23/3/20 1 Introduction As for any index, 3 alternatives for data entries k*: 1. Data record with key value k 2. 3. § Choice orthogonal to the indexing technique § Hash-based indexes are the best for equality selections. Cannot support range searches. § Static and dynamic hashing techniques exist; trade-offs similar to ISAM

T ransactions, Recovery and Concurrency (II) Concurrency Control 3/30/20 1 Concurrency Control Methods • Locking Mechanism The idea of locking some data item X is to: • give a transaction exclusive use of the data item X, • do not restrict the access of other data items. This prevents one transaction from changing a data

Robust Odometry Estimation for RGB-D Cameras Christian Kerl, Jürgen Sturm, and Daniel Cremers Abstract— The goal of our work is to provide a fast and accurate method to estimate the camera motion from RGB-D images. Our approach registers two consecutive RGB-D frames directly upon each other by minimizing the photometric error. We estimate the camera
